ACU16-C/NHB32-C

Owner’s Manual Addendum

Please make the following changes and additions to the ACU16-C/NHB32-C owner’s manual. Some of

these are due to the ACU16-C/NHB32-C system software upgrade, while others are corrections and

supplementary explanations.

Changes due to the software upgrade

❏ Support for CobraNet “Low Latency” (system software v1.10)

In conjunction with the upgrade to system software V1.10, the latency setting that had been ﬁxed at 5.33 ms can now be

selected from three choices (5.33 ms/2.67 ms/1.33 ms). This allows even lower-latency distribution of audio signals. In

addition, you can now make connections at the desired latency to digital mixers such as the PM5D or digital mixing engines

such as the DME64N/24N via the Yamaha “MY16-C” card.

Changing the latency can be done in conjunction with NetworkAmp Manager V1.1.0E. For the procedure, refer to the

NetworkAmp Manager owner’s manual (PDF format).

The latency and audio bit depth settings will determine the limits on the number of channels that can be distributed in one

bundle, and the number of bundles that can be distributed.

• NHB32-C

•ACU16-C

If two or more different latencies exist in a CobraNet network, it may become impossible for the various devices to

communicate correctly. You must make sure that all CobraNet devices in a single network have the same latency setting.

Additions and corrections

❏ Cable Length & Switching Hubs

The maximum length of a cable used in a 100Base-T Ethernet network is 100 m (a maximum of 2 km for a multimode optical

ﬁber cable), but depending on the type of cable used and on the performance of the switching hub, there are cases in which

this length cannot be guaranteed. Three or four switching hubs can be connected, but this also will depend on the

performance of the switching hub.

❏ “System Requirements (NetworkAmp Manager)” (page 10)

The following items have been added to the operating requirements for NetworkAmp Manager.

•If your computer has HyperThreading Technology, you must disable it when connecting via USB.

•This software cannot be used on a computer that has multiple CPUs (e.g., Intel’s Xeon processor or AMD’s Opteron

processor).

•This software cannot be used on a computer that has a dual core CPU (e.g., Intel’s Pentium-D processor or AMD’s

Athlon64 x2 processor).

•This software cannot be used on a computer running Windows XP x64 Edition.

❏ “Installing Acrobat Reader” (page 12)

Incorrect—To view the Network Amp Manager Owner’s Manual, you’ll need to install the Adobe Acrobat Reader

software, which is included on the CD-ROM. If you already have this software installed, skip this section.

Correct—To view the NetworkAmp Manager Owner’s Manual (PDF format), Adobe Reader software (free of charge)

must be installed. If you don’t have Adobe Reader, please download it from the Adobe Corporation’s website.

http://www.adobe.com

❏ “PRIMARY & SECONDARY CobraNet ports” (page 22)

Incorrect—Primary and secondary can be used to build redundancy into systems. Under normal conditions, the

ACU16-C uses the PRIMARY port. However, if communication via that port fails, it will automatically switch to the

SECONDARY port and operation will continue uninterrupted.

Correct—Primary and secondary can be used to build redundancy into systems. Under normal conditions, the ACU16-

C uses the PRIMARY port. However, if system problems such as port malfunction or broken cable occur in the PRIMARY

port, it will automatically switch to the SECONDARY port. The audio signal will be momentarily interrupted, but the

duration of the interruption will depend on the performance and settings of the hub, and on the structure of the system.

❏ “Introduction” (page 25)

Incorrect—Up to eight NHB32-Cs can be used on a single CobraNet network, providing bridging between 512

CobraNet audio channels and 512 AES/EBU format inputs and outputs.

Correct—Up to eight NHB32-Cs can be used on a single CobraNet network, providing bridging a maximum (total

inputs and outputs) of 256 channels of CobraNet audio and AES/EBU audio.

❏ “CobraNet Primary & Secondary” (page 35)

Incorrect—In the ﬁrst example, if a primary connection fails, the system automatically switches to secondary and

operation continues uninterrupted. However, if the switching hub fails, the entire system stops working. In the second

example, individual switching hubs are used for primary and secondary, so even if switching hub A fails, operation

continues on secondary via switching hub B.

Correct—In the ﬁrst example, if a primary connection fails, the system automatically switches to secondary. However if

the switching hub fails, the entire system stops working. In the second example, individual switching hubs are used for

primary and secondary, so even if switching hub A fails, operation continues on secondary via switching hub B.

Be aware that with either connection, the time required in order to switch between primary and secondary will depend on

the performance and settings of the hub.

❏ “CobraNet Primary & Secondary, Ex. 2” (page 35)

In consideration of a case in which the primary connection fails, connect switching hub A and switching hub B.

Notes on rack-mounting the unit

If you install the ACU16-C/NHB32-C along with another

ACU16-C/NHB32-C or other device in a rack that is not well

ventilated, the temperature inside the rack may rise due to the

heat generated from the devices and the devices may be unable

to perform properly. When you rack-mount the unit, be sure

to keep a gap of 1U (4.5cm) above and below the unit for better

ventilation. Also, install the ventilation panels in these gaps or

remove the partition panels.

If the temperature inside the rack is expected to be 40°C or

higher (in this case, the room temperature is generally about

30°C or higher), install the fan kit on the top shelf of the rack,

and install the ventilation panels between devices or remove

the partition panels. The fan kit must generate a maximum

wind of 1.6m

/min or higher and a maximum static pressure

of 5mmH

O or higher.

Anmerkungen zum Rackeinbau des Geräts

Wenn Sie den ACU16-C/NHB32-C gemeinsam mit einem

anderen ACU16-C/NHB32-C oder einem Gerät mit

mangelhafter Lüftung in ein Rack einbauen, könnte die

Te mperatur im Innern des Racks rapide ansteigen und Ausfälle

der vorhandenen Geräte verursachen. Lassen Sie über und unter

Geräten in einem Rack jeweils 1HE (4,5cm) frei, um eine

ausreichende Luftzirkulation zu gewährleisten. In diesen

Öffnungen müssen Lüftungsblenden angebracht werden.

Außerdem sind eventuell vorhandene Trennplatten zu entfernen.

Wenn die Temperatur im Innern des Racks die 40°C-Marke zu

übersteigen droht (was der Fall ist, wenn die Raumtemperatur

mindestens 30°C beträgt), müssen Sie ganz oben im Rack eine

Lüftereinheit und zwischen den Geräten Lüftungsblenden

einbauen. Trennplatten zwischen diesen Partien müssen

entfernt werden. Die Lüftereinheit muss einen Luftstrom von

mindestens 1,6m

/min und einen statischen Druck von

5mmH

O oder mehr erzeugen.

Remarques concernant l’installation de l’unité dans un rack

Si vous installez l’ACU16-C/NHB32-C dans le même rack

qu’un deuxième ACU16-C/NHB32-C ou tout autre dispositif

avec une ventilation autonome plutôt limitée, la température au

sein du rack pourrait très vite monter à des valeurs qui

empêchent les unités de fonctionner correctement. De ce fait,

pour le montage en rack, il convient de laisser un espace d’1U

(4,5cm) au-dessus et en dessous de tels dispositifs pour assurer

une bonne circulation d’air frais. De plus, il faut couvrir les

ouvertures ainsi laissées avec des panneaux de ventilation.

Retirez toute cloison éventuellement présente entre deux unités.

Si la température au sein du rack risque de monter au-delà de

40°C (auquel cas la température ambiante s’élève à 30°C ou

plus), installez un kit de ventilation en haut du rack et des

panneaux de ventilation entre les unités. Retirez en outre les

cloisons qui les séparent. Le kit de ventilation doit générer un

ﬂux d’air supérieur à 1,6m

/min et une pression statique de

5mmH

O ou plus.

Notas acerca de la instalación en rack de la unidad

Si instala el ACU16-C/NHB32-C junto con otro ACU16-C/

NHB32-C u otro dispositivo en un armario rack que no esté

correctamente ventilado, la temperatura en el interior del

armario puede elevarse debido al calor generado por los

propios dispositivos y afectar al correcto funcionamiento de

los mismos. Cuando instale la unidad en rack, asegúrese de

dejar una separación de 1U (4.5cm) por encima y por debajo

de la unidad con el ﬁn de conseguir una correcta ventilación.

Además, instale los paneles de ventilación en estas

separaciones o elimine los paneles de partición.

Si se calcula que la temperatura en el interior del rack sea de

40°C o más (en este caso, cuando la temperatura de la

habitación es de 30°C o superior), instale el kit de ventilación

en la parte superior del armario rack e instale los paneles de

ventilación entre los dispositivos o elimine los paneles de

división. El kit de ventilación debe generar un caudal mínimo

de 1.6m

/min o superior con una presión estática mínima de 5

mm H

O o superior.

Important Note for PC-N Series Power

Ampliﬁer Users

When you are using the ACU16-C connected to a PC9500N or

PC4800N power ampliﬁer, the NetworkAmp Manager's meter

may not display the correct value, depending on your power

ampliﬁer. Please check your power ampliﬁer for the following

items to ﬁnd out whether the problem has been ﬁxed on your

ampliﬁer:

Locate the product serial number label on the packing container

or on the rear panel of the power ampliﬁer.

•If the ﬁrst two alphabetical letters in the serial number are IL,

IM, IN, IO, IP, IX, IY, IZ, or JH, the problem may not have

been ﬁxed on the ampliﬁer. Otherwise, you can assume that

the problem has been ﬁxed on your ampliﬁer.

• On units that have a serial number that begins with any of the

letter combinations described above, if there is a green round

sticker adjacent to the serial number label, the problem has

been ﬁxed on the unit.

If the problem has not been ﬁxed on your power ampliﬁer,

contact your Yamaha dealer.

Wichtiger Hinweis für den Einsatz von

Endstufen der PC-N-Serie

Wenn Sie den ACU16-C an eine Endstufe des Typs PC9500N

oder PC4800N anschließen, zeigen die Meter von NetworkAmp

Manager eventuell nicht den richtigen Wert an. Wenn das bei

Ihnen der Fall ist, können Sie folgendermaßen ermitteln, ob das

Problem der Endstufe behoben werden muss:

Bringen Sie die Seriennummer Ihrer Endstufe in Erfahrung.

Diese ﬁnden Sie auf dem Lieferkarton und dem rückseitigen

Typenschild.

•Wenn die ersten beiden Buchstaben der Seriennummer „IL”,

„IM”, „IN”, „IO”, „IP”, „IX”, „IY”, „IZ” oder „JH” lauten,

bedarf die Endstufe eventuell noch einer Aktualisierung.

Andernfalls können Sie davon ausgehen, dass das Problem

bereits behoben wurde.

•Auf Geräten, deren Seriennummer mit den oben erwähnten

Buchstaben beginnt und bei denen das Problem bereits

behoben wurde, beﬁndet sich neben dem Typenschild ein

runder grüner Aufkleber.

Fehlt dieser Aufkleber auf Ihrer Endstufe, so wenden Sie sich

Remarque importante à l’attention

des utilisateurs d’un ampliﬁcateur de

puissance de la série PC-N

Quand l’ACU16-C est branché à un ampliﬁcateur de puissance

PC9500N ou PC4800N, il se peut (selon l’ampli de puissance)

que l’afﬁchage de niveau de NetworkAmp Manager n’indique

pas la valeur correcte. Contrôlez alors le numéro de série de

votre ampliﬁcateur comme suit pour vériﬁer si ce problème doit

être corrigé ou non:

Vériﬁez le numéro de série de l’ampliﬁcateur sur l’emballage ou

le panneau arrière de l’appareil.

•Si les deux premières lettres du numéro de série

correspondent à “IL”, “IM”, “IN”, “IO”, “IP”, “IX”, “IY”, “IZ” ou

“JH”, le problème n’a peut-être pas été corrigé sur

l’ampliﬁcateur. Si les lettres initiales du numéro de série

diffèrent des caractères ci-dessus, vous pouvez partir du

principe que le problème a été corrigé sur votre

ampliﬁcateur.

•Certains ampliﬁcateurs dont le numéro de série commence

par une paire de lettres mentionnée ci-dessus pourraient

comporter une vignette ronde et verte collée à côté de

l’étiquette du numéro de série. La présence de cette vignette

signiﬁe que le problème a été corrigé sur l’appareil en

question.

Si le problème n’a pas été corrigé sur votre ampliﬁcateur de

puissance, contactez votre revendeur Yamaha.

Nota importante para los usuarios de

los ampliﬁcadores de la serie PC-N

Si utiliza el ACU16-C conectado a un ampliﬁcador PC9500N o

PC4800N, el indicador NetworkAmp del Manager puede que no

visualice el valor correcto, dependiendo de su ampliﬁcador.

Compruebe los siguientes elementos en su ampliﬁcador para

saber si el problema se ha solucionado:

Localice la etiqueta del número de serie del producto en el

embalaje o en el panel posterior del ampliﬁcador.

•Si las dos primeras letras del número de serie son “IL”, “IM”,

“IN”, “IO”, “IP”, “IX”, “IY”, “IZ” o “JH”, es posible que el

problema no se haya solucionado en el ampliﬁcador. De lo

contrario, puede asumir que el problema se ha solucionado

en el ampliﬁcador.

• En las unidades con números de serie que empiecen por

cualquier serie de letras mencionada, si observa un punto

verde al lado de la etiqueta del número de serie, el problema

se ha solucionado en la unidad.

•Connect this unit’s power cord only to an AC outlet of the type stated in this

Owner’s Man-

ual

or as marked on the unit. Failure to do so is a ﬁre and electrical shock hazard.

•Do not allow water to enter this unit or allow the unit to become wet. Fire or electrical shock

may result.

•Do not place heavy objects, including this unit, on top of the power cord. A damaged power

cord is a ﬁre and electrical shock hazard. In particular, be careful not to place heavy objects

on a power cord covered by a carpet.

•Do not place a container with liquid or small metal objects on top of this unit. Liquid or

metal objects inside this unit are a ﬁre and electrical shock hazard.

Operation

•Do not scratch, bend, twist, pull, or heat the power cord. A damaged power cord is a ﬁre

and electrical shock hazard.

•Do not remove the unit’s cover. You could receive an electrical shock. If you think internal

inspection, maintenance, or repair is necessary, contact your dealer.

•Do not modify the unit. Doing so is a ﬁre and electrical shock hazard.

•If lightning begins to occur, turn off the power switch of the unit as soon as possible, and

unplug the power cable plug from the electrical outlet.

•If there is a possibility of lightning, do not touch the power cable plug if it is still connected.

Doing so may be an electrical shock hazard.

•Use only the included power cord with this unit. Using other types may be a ﬁre and elec-

trical shock hazard.

In case an abnormality occurs during operation

•If the power cord is damaged (i.e., cut or a bare wire is exposed), ask your dealer for a

replacement. Using the unit with a damaged power cord is a ﬁre and electrical shock hazard.

•If you notice any abnormality, such as smoke, odor, or noise, or if a foreign object or liquid

gets inside the unit, turn it off immediately. Disconnect the power cord. Consult your dealer

for repair. Using the unit in this condition is a ﬁre and electrical shock hazard.

Cautions

Installation

•Keep this unit away from the following locations:

—Locations exposed to oil splashes or steam, such as near cooking stoves, humidiﬁers, etc.

—Unstable surfaces, such as a wobbly table or slope.

—Locations exposed to excessive heat, such as inside a car with all the windows closed, or

places that receive direct sunlight.

—Locations subject to excessive humidity or dust accumulation.

•Hold the power cord plug when disconnecting it from an AC outlet. Never pull the cord. A

damaged power cord is a potential ﬁre and electrical shock hazard.

•Do not touch the power plug with wet hands. Doing so is a potential electrical shock hazard.

•This unit has ventilation holes to prevent the internal temperature from rising too high. Do

not block them. Blocked ventilation holes are a ﬁre hazard. In particular, do not operate the

unit while it’s on its side, is upside down, or while it’s covered with a cloth or dust sheet.

•When installing the unit in a rack, you must use the rack-mounting screw holes at the rear

in addition to those on the front panel.

•When rack-mounting or stacking several units, always leave at least 1U (i.e., about 4.5 cm)

of free space above and below the unit for normal ventilation. If the airﬂow is restricted, the

unit may overheat, which could cause a ﬁre.

•To relocate the unit, turn the power switch off, remove the power plug from the AC outlet,

and remove all connecting cables. Damaged cables may cause ﬁre or electrical shock.

•This unit is equipped with a dedicated ground connection to prevent electrical shock.

Before connecting the power plug to an AC outlet, be sure to ground the unit. If the power

cord has a three-pin plug, it will provide sufﬁcient grounding so long as the AC outlet is

grounded correctly.

Operation

•If you know you will not use this unit for a long period of time, such as when going on vaca-

tion, remove the power plug from the AC outlet. Leaving it connected is a potential ﬁre haz-

ard.

Maintenance

•To prevent electrical shock when cleaning the unit, remove the power plug from the AC out-

let.
