AMPLIFIER SETTINGS
Signal Input and Output Configurations
The input section of the amplifier consists of a phase switch that sets the output configuration,
gain controls, and RCA inputs. The input section makes it easy to adapt this amplifier to most
system configurations.
Input Gain
The Orion Cobalt CO500.1 and CO800.1 amplifiers have level adjustments to allow for easy
integration with any source unit. The input sensitivity can be adjusted from 200mV to 5V. Refer
to Testing the System and Adjusting the Sound of the System sections of this guide for detailed
instructions on setting the gain.
Phase Switches
0° - leaves output unaffected. The output signal is in phase with the input signal.
180° - inverts the output. The channel is 180° output of phase. This configuration is
useful for inverting the phase of subwoofers to improve staging in a vehicle. This is
also used when bridging two amplifiers into one speaker.
Auxiliary Output Configurations
The auxiliary outputs on Orion Cobalt amplifiers offer easy, unlimited system expansion. Routing
signal from a source unit, pre-amplifier, or equalizer is a matter of connecting RCAs to the RCA
Inputs and the RCA outputs to your next Orion Cobalt amplifier in the signal chain. The signal
passes through a buffer stage so that several amplifiers can be daisy chained without signal loss
or overloading of the source unit. This maximizes the signal output and minimizes the potential
for system noise.
Internal Crossover
The crossover section of the Orion Cobalt CO500.1 and CO800.1 amplifiers is continuously vari-
able and extremely flexible.
When using Orion Cobalt loudspeakers, minor deviations from the recommended frequency
ranges can provide superior results depending on your speaker locations and your vehicle
acoustics. Setting crossover frequencies higher than recommended will not cause damage and
may provide superior sonic results depending on your system's performance goals. Refer to your
6 © 2007 directed electronics—all rights reserved
loudspeaker owner's manual for assistance in choosing the proper crossover frequencies for
your system.
Low-Pass Crossover
The low-pass crossover is active with a 2nd order (12dB per octave) slope. The low-pass crossover
is continuously variable from 50Hz to 500Hz.
Remote Bass Operation
The remote bass port provides easy remote access to the internal bass gain structure of the
power amplifier. The bass gain is centered at 44Hz. The RGC-2 plugs into the amplifier via the
1/8" mini jack plug. The RGC-2 can be installed in the front of the vehicle to control the ampli-
fier bass gain level. The RGC-2 can be used as a bass level control when used on an amplifier
dedicated to subwoofers.

Bridging
For bridging into a single speaker load, the Orion Cobalt CO500.1 and CO800.1 have the ability
to be bridged with another amplifier of the same model. To do this you must set the PHASE
switch on the (slave) amp, move the phase switch from 0 to 180, exactly opposite of the master
amp. Refer to the Phase Switch section of this guide.
Be sure to set all adjustment on both amplifiers exactly the same except for the phase switch.
The phase switch on the master amplifier should be 0 and the slave amplifier should be 180.
For the speaker connections, connect the positive (+) speaker lead from the speaker to the posi-
tive (+) speaker terminal of the master amplifier. On the negative (-) speaker connection, take
the negative (-) speaker terminal of the master amplifier and connect it directly to the nega-
tive (-) speaker terminal of the (slave) amplifier. The remaining positive (+) speaker terminal of
the (slave) amplifier must be connected to the negative (-) speaker lead from the speaker. The
impedance of the speaker must not be less than 4 ohms
NOTE: For best results, connect both negative speaker terminals on the master amp to both
negative terminals on the slave amp using at least 12 AWG cable.

AMPLIFIER INSTALLATION
Choosing Mounting Locations
The location of your amplifier will depend on several important issues. Due to the low profile
size of the Orion Cobalt amplifiers, there are many possible installation locations that will yield
satisfactory amplifier performance. Always mount the amplifier in a place that protects the
amplifier from the elements. In addition, mount the amplifier on a stable, flat surface.
NOTE: Mounting amplifiers upside down is not recommended and may cause premature
thermal shutdown.
WARNING! Do not mount any amplifier in the engine compartment. Amplifiers are not
designed to endure the harsh environment of the exterior elements.
Passenger Compartment
If you are going to mount the amplifier in the passenger compartment, make sure you have
adequate room for ventilation. The amplifiers have been designed to make under-seat mount-
ing possible. When mounting your amplifier under a seat or similar area, keep a minimum of 1"
of clearance around the amplifier for adequate cooling.
8 © 2007 directed electronics—all rights reserved
Trunk Compartment
Mounting your amplifier in the trunk provides excellent performance as long as you do not
restrict the airflow around the heatsink of the amplifier. For optimal results, mount the amplifier
with as much clearance as possible. This type of mounting will yield the best cooling due to the
convection effect of the amplifier chassis.
General Precautions and Installation Tips
WARNING! Be careful not to cut or drill into gas tanks, fuel lines, brake lines, hydraulic lines,
vacuum lines, or electrical wiring when working on your vehicle.
Disconnect the vehicle's ground wire at the battery before making or breaking connections to
the audio system's power supply terminals.
Do not use this amplifier unmounted. Failing to securely mount the amplifier can result in
damage or injury, particularly in the event of an accident. An unmounted amplifier becomes a
dangerous projectile in the event of a crash. Never mount the amplifier where it might get wet.
Mount the amplifier so the wire connections will not be pulled. Route the wires where they will
not be scraped, pinched or damaged in any fashion.
The +12V power supply wire must be fused as close as possible to the battery terminal, ideally
within 18". Use the recommended fuse size or circuit breaker listed in the Power Connections
section of this manual.
If you need to replace the fuse plugged into the side of the amplifier, replace the fuse with the
same size ATC / MAXI type fuse that came with the amplifier. If you are not sure as to the correct
value, refer to the Power Connections section of this manual for details. Using a higher current
fuse may result in damage to the amplifier that is not covered under warranty.
NOTE: Make sure all the equipment in the system is turned off when making or breaking con-
nections to the input RCAs or speaker terminals. Turn on the system and slowly turn up
the volume control only after double checking all wire connections.
Power for systems with a single amplifier can be supplied by most automotive electrical systems.
Systems with multiple amplifiers may require a higher capacity battery, alternator or the use of a
storage capacitor. We strongly recommend the use of a Directed Audio Essentials power capaci-
tor with an extra battery in larger stereo systems.
Orion Cobalt amplifiers generate a certain amount of heat as part of normal operation. Be sure
the area around the amplifier is unobstructed to allow adequate air circulation. Remember,
beach blankets, last week's laundry, school books and homework papers located on top of the
amplifier do not improve air flow and may become damaged.
Step By Step Installation
Step 1 Determine the location for the amplifier. Refer to the Choosing Mounting
Locations section of this guide for detailed information.
Step 2 Decide on the system configuration for your amplifier. For system suggestions,
refer to the Speaker Connections section of this guide.
Step 3 Run all the wires from the amplifier location to the speakers, source unit, and bat-
tery. Do not connect the battery at this time. Be sure to run RCAs and power and
speaker wires away from factory electrical wires and system as they pose a great
potential for induced system noise.
Step 4 Pre-drill amplifier mounting holes. Be sure to "think before you drill". Gas tanks,
fuel lines, and other obstructions have a nasty way of hiding themselves. For best
© 2007 directed electronics—all rights reserved 9
results use a marking pen to mark the mounting holes and pre-drill these holes
with a standard 1/8" drill bit.
Step 5 Mount the amplifier. Make sure the amplifier is mounted on a flat surface. If this
is not possible, do not over tighten the screws so that the chassis of the amplifier
is twisted or bent.
Step 6 Turn the vehicle's key switch to the off position.
Step 7 Disconnect the vehicle's battery ground terminal.
Step 8 Connect power wires to the amplifier (ground first, then 12 V(+) and REM).
Step 9 Connect the RCA and speaker wires to the amplifier. Check the quality of your
speakers and signal connections. This will determine the ultimate performance of
your Orion Cobalt amplifier. Refer to the Signal Input and Output Level Controls
and Speaker Connections sections of this guide for correct wiring instructions.
Step 10 Reconnect the ground terminal to the battery after power, speaker, and RCA con-
nections are completed.
Step 11 Set crossovers. Refer to the Internal Crossover Configuration section of this manual
for detailed instructions.
Step 12 Once satisfied that all connections and settings are correct, install the fuse located
near the vehicle's battery and proceed to the Testing the System section of this
manual.
WARNING! Never exceed the recommended fuse size of this amplifier. Failure to do so will
result in the voiding of your warranty and possible damage to the amplifier.
SET UP AND TROUBLESHOOTING
Testing the System
After you have completed the installation, you need to test the system. This will help ensure years
of trouble-free operation. Please refer to the listed steps below when testing the sound of your
Orion Cobalt system.
Step 1 Check all the wiring connections to be sure they are correct and secure.
Step 2 Turn the signal source volume control all the way down. Set any tone controls to
their flat or defeated positions. This includes the loudness control.
Step 3 Turn the level controls of the amplifier to their minimum positions.
Step 4 Turn the source unit on. Check to see if the power LED located on the connection
side of the amplifier is on. If not, please refer to the Power Connections and the
Troubleshooting Tips sections of this manual for instructions.
Step 5 If using an aftermarket source unit, turn the level controls of the amplifier about
one quarter of a turn. Slowly increase the volume level of the source unit to so that
you can hear the output of the system. If no sound is heard or if the output is dis-
torted, turn the system off immediately. Refer to the Power Connections and the
Troubleshooting Tips sections of this manual to solve your installation problems.
Step 6 Check to make sure the output for each channel is correct. If the active crossovers
are used, check to make sure that each output is correct from the amplifier. When
using active crossovers on midrange and tweeters, do not use crossover frequen-
cies lower than recommended. If the system is not configured properly, refer to
the Internal Crossover Configuration section of this manual and take corrective
action.
Step 7 If the output is clear and undistorted, continue to the Adjusting the Sound of the
10 © 2007 directed electronics—all rights reserved
System section of this manual.
Adjusting the Sound of the System
Once you have checked the system's operation, adjust the sound of the system. Adjusting the
sound of the system is accomplished by setting the level controls and adjusting the internal
crossovers.
Step 1 Turn the signal source volume control all the way down. Set any tone controls to
their flat or defeated positions. This includes the loudness control.
Step 2 Turn the level controls of the amplifier to their minimum positions.
Step 3 Choose music with high dynamic content that you like, with which you are famil-
iar, and will be used most often in the system.
Step 4 Turn the source unit's volume control up to its highest undistorted output level. If
you lack test equipment, this point occurs between 3/4 to full volume depending
on the quality of your source unit. Listen for any audible distortion. If any distor-
tion is audible, reduce the volume of the source unit until you have an undistorted
output. Leave the volume control at this position during your system tuning.
Step 5 While listening to your chosen dynamic music, turn up the level control corre-
sponding to the midrange output until you hear slight distortion and turn the
level control back slightly for an undistorted output. Depending on your system,
the midrange and tweeter output may be on the same output channels.
Step 6 Turn up the level control corresponding to the tweeter output until you hear
slight distortion and turn back the level control slightly for an undistorted output.
Depending on your system the midrange and tweeter output may be on the same
output channels.
Step 7 Fine-tune the output level between midrange and tweeters. Refer to the Internal
Crossover Configuration section of this manual for detailed instructions.
Step 8 Repeat Steps 5-7 for the rear speakers. If you do not have rear speakers continue
to Step 10.
Step 9 Set levels between the front and rear midrange and tweeters for optimum front/
rear balance.
Step 10 Turn up the level control corresponding to the woofer output until you hear slight
distortion and turn back the level control slightly for an undistorted output.
Step 11 Fine-tune the output level between satellite speakers and the woofers. Refer to
the Internal Crossover Configuration section of this manual for detailed instruc-
tions. If using an RGC-2, adjust the level to the bass output of the woofer to match
the sonic requirements of the system.
Step 12 Enjoy your awesome Orion Cobalt sound system.

RÉGLAGES DE L'AMPLIFICATEUR
Configurations d'entrée et sortie du signal
La section d'entrée de l'amplificateur comporte un commutateur de phase qui règle la configura-
tion de sortie, les contrôles de gain et les entrées RCA. Elle facilite l'adaptation de l'amplificateur
à la plupart des configurations de systèmes.
Gain d'entrée
Les amplificateurs Orion Cobalt CO500.1 et CO800.1 peuvent ajuster leurs niveaux pour s'intégrer
facilement à tout récepteur. La sensibilité d'entrée est réglable de 200 mV à 5 V. Consultez les
sections Essai du système et Réglage sonore du système du présent guide pour des instructions
détaillées sur le réglage du gain.
© 2007 directed electronics—all rights reserved 17
Commutateurs de phase
0° - ne change pas la sortie, qui reste en phase avec le signal d'entrée.
180° - inverse la sortie. La sortie du canal est déphasée de 180°. Cette configuration
sert à inverser la phase des caissons de basses pour améliorer l'activation dans un véhi-
cule. Elle permet aussi de brancher en pont deux amplificateurs dans un haut-parleur.
Configurations des sorties auxiliaires
Les sorties auxiliaires des amplificateurs Orion Cobalt permettent une expansion facile et illimi-
tée du système. Il suffit pour acheminer le signal d'une source, d'un préamplificateur ou d'un
compensateur de raccorder des fiches RCA aux entrées RCA et les sorties RCA à l'amplificateur
Orion Cobalt suivant dans la chaîne. Le signal passe par un étage-tampon pour permettre de
relier plusieurs amplificateurs en guirlande sans perte de signal ni surcharge du récepteur. Ceci
maximise la sortie du signal et minimise le risque de bruit généré par le système.
Configuration du répartiteur interne
La répartition des amplificateurs Orion Cobalt CO500.1 et CO800.1 offre une variation continue
et est extrêmement flexible.
Avec les haut-parleurs Orion Cobalt, des déviations mineures des gammes de fréquence recom-
mandées peuvent donner des résultats supérieurs, selon l'emplacement des haut-parleurs et
l'acoustique de votre véhicule. Des fréquences de répartition supérieures aux recommandations
ne causeront aucun dommage et pourraient produire des résultats supérieurs selon les objectifs
de rendement de votre système. Consultez le manuel de votre haut-parleur pour vous aider à
choisir les fréquences de répartition appropriées pour votre système.
Répartiteur passe-bas
Le répartiteur passe-bas est actif sur une pente au second degré de 12 dB par octave. Le répar-
titeur passe-bas est réglable en continu de 50 Hz à 500 Hz.
Contrôle à distance des basses
Le port de contrôle à distance des basses permet un accès à distance facile à la structure interne
de gain des basses fréquences de l'amplificateur. Le gain de basses est centré à 44 Hz. Le RGC-2
se branche dans l'amplificateur par la mini-prise 1/8". Le RGC-2 peut être installé à l'avant du
véhicule pour contrôler le niveau de gain de basses de l'amplificateur. Le RGC-2 peut servir de
contrôle du niveau des basses sur un amplificateur dédié aux caissons de basses.
CÂBLAGE DE L'AMPLIFICATEUR
Raccords d'alimentation pour les Orion Cobalt CO500.1 et CO800.1
Fusibles Orion Cobalt CO500.1: 2 x 20 AMP ATC / Fusibles CO800.1: 2 x 30 AMP ATC
Les raccords d'alimentation acceptent du câble jusqu'à 4 AWG.
Câbles d'alimentation et mise à la masse 4 AWG recommandés pour rendement opti-
mal.
Raccordez 12V+ à la batterie par le porte-fusible pour fournir une alimentation princi-
pale +12V à l'amplificateur.
Le fusible du câble d'alimentation doit être au maximum à 18" de la batterie.
Utilisez une bonne mise à la masse au châssis pour l'amplificateur, aussi près que pos-
sible de l'amplificateur.
18 © 2007 directed electronics—all rights reserved
Raccordez la borne REM à la borne d'allumage à distance du récepteur pour fournir
l'alimentation +12V requise pour allumer l'amplificateur.
Mettez du câble de mise à la masse supplémentaire entre la borne négative de la bat-
terie et le châssis.
Câblage des haut-parleurs CO500.1/CO800.1
Les amplificateurs Orion Cobalt CO500.1 and CO800.1 disposent de deux bornes positives et deux bornes
gatives de sortie pour le raccord des haut-parleurs à l'amplificateur. Ces amplificateurs étant mono, les
raccords de haut-parleur sont mis en parallèle à l'interne. Chaque amplificateur est stable à 2 Ω.
Diagramme de référence: page 6 (figure 3)
Branchement en pont
Pour le branchement en pont d'un seul haut-parleur, les Orion Cobalt CO500.1 et CO800.1
peuvent être branchés en pont avec un autre amplificateur du même modèle. Pour cela, vous
devez changer le commutateur PHASE de l'amplificateur asservi de 0 à 180, à l'opposé de
l'amplificateur maître. Consultez la section Commutateurs de phase du présent guide.
Assurez-vous que tous les réglages (sauf la commutation de phase) soient les mêmes sur les
deux amplificateurs. La phase de l'amplificateur maître doit être à 0 et celle de l'amplificateur
asservi à 180. Pour ce qui est des haut-parleurs, raccordez la borne positive (+) du haut-parleur à
la borne de haut-parleur positive (+) de l'amplificateur maître. Raccordez directement la borne
de haut-parleur négative (-) de l'amplificateur maître à la borne de haut-parleur négative (-) de
l'amplificateur asservi. La borne de haut-parleur positive (+) de l'amplificateur asservi doit être
raccordée à la borne négative (-) du haut-parleur. L'impédance du haut-parleur doit être d'au
moins 4 ohms.
NOTE: Pour de meilleurs résultats, raccordez les deux bornes négatives de haut-parleur de
l'amplificateur maître aux deux bornes négatives de l'amplificateur asservi avec du câble d'au
moins 12 AWG.
Diagramme de référence: page 7 (figura 4)
INSTALLATION DE L'AMPLIFICATEUR
Choix de l'emplacement du montage
L'emplacement de votre amplificateur dépend de plusieurs facteurs importants. Le profil bas des
amplificateurs Orion Cobalt permet le choix de plusieurs emplacements pour un bon rendement.
Assurez-vous de monter l'amplificateur de manière à le protéger des éléments. Montez-le sur
une surface stable et plate.
NOTE: Le montage sens dessus dessous n'est pas recommandé: il pourrait causer un arrêt
à la surchauffe.
ATTENTION! Ne montez aucun amplificateur dans le compartiment moteur. Ils ne sont pas
conçus pour endurer les épreuves des éléments extérieurs.
Espace du passager
Pour monter l'amplificateur dans l'espace du passager, assurez-vous qu'il y a assez d'espace pour
la ventilation. Il est possible de le monter sous le siège. Pour ce faire, ou pour tout emplacement
similaire, assurez-vous de disposer d'un espace minimum de 1" autour de l'amplificateur pour
© 2007 directed electronics—all rights reserved 19
un refroidissement adéquat.
Coffre
Le montage dans le coffre produira d'excellents résultats pourvu que vous ne limitiez pas la
circulation d'air autour du dissipateur thermique de l'amplificateur. Pour de meilleurs résultats,
donnez à l'amplificateur autant d'espace libre que possible. L'effet de convection du châssis de
l'amplificateur assurera un refroidissement optimal pour ce type de montage.
Précautions générales et conseils d'installation
ATTENTION! Faites attention à ne pas couper ni percer le réservoir de carburant, les conduits
d'essence, les conduites de frein, les conduites hydrauliques, les conduites à
dépression ou le câblage électrique quand vous travaillez sur votre véhicule.
Déconnectez le câble de mise à la masse de la batterie du véhicule avant de faire ou défaire des
raccords aux bornes d'alimentation du système audio.
N'utilisez pas cet amplificateur avant de l'avoir monté. Faute d'un montage sécuritaire, des
dégâts et blessures sont possibles, surtout en cas d'accident. Un amplificateur non monté est un
projectile dangereux en cas de collision. Ne montez jamais un amplificateur là où il pourrait être
mouillé. Assurez-vous qu'on ne pourra tirer sur les câbles raccordés. Placez les câbles là où ils ne
pourront être raclés, pincés ou endommagés en aucune manière.
Le fusible du câble d'alimentation +12V doit être aussi près que possible de la borne de la bat-
terie, idéalement 18" ou moins. Utilisez le calibre de fusible ou disjoncteur recommandé dans la
section Raccords d'alimentation du présent manuel.
S'il faut remplacer le fusible branché sur le côté de l'amplificateur, utilisez le même type et le
même calibre de fusible ATC / MAXI que celui que vous remplacez. Si vous n'êtes pas sûr de la
valeur correcte, Consultez la section Raccords d'alimentation pour plus de détails. Un fusible de
calibre plus élevé peut causer à l'amplificateur des dégâts non couverts par la garantie.
NOTE: Assurez-vous que tout l'équipement du système est éteint avant de faire ou défaire des
raccords aux bornes d'entrée RCA ou de haut-parleur. Allumez le système et montez
lentement le volume seulement après avoir revérifié tous vos raccords de câbles.
La plupart des systèmes électriques d'automobiles peuvent alimenter un système à un seul
amplificateur. Des amplificateurs multiples pourraient exiger une batterie à capacité plus élevée,
un alternateur ou un condensateur-magasin. Pour les plus gros systèmes, nous recommandons
fortement un condensateur de puissance Directed Audio Essentials et une batterie supplémen-
taire.
Les amplificateurs Orion Cobalt génèrent une certaine chaleur en fonctionnement normal.
L'espace entourant l'amplificateur devrait être libre pour permettre une circulation d'air adé-
quate. Les serviettes de plage, la lessive de la semaine dernière, les manuels scolaires et les
devoirs empilés sur l'amplificateur nuisent à la circulation et peuvent subir des dommages.
Installation étape par étape
Étape 1 Choissez l'emplacement de l'amplificateur. Consultez la section Choix de
l'emplacement du montage du présent guide pour plus de détails.
Étape 2 Choissez la configuration de système pour votre amplificateur. Consultez la sec-
tion Câblage des haut-parleurs du présent guide pour des suggestions.
Étape 3 Acheminez tous les câbles de l'amplificateur aux haut-parleurs, à la source et
à la batterie. Ne raccordez pas la batterie maintenant. Faites passer les câbles
