3. PRODUCT OVERVIEW
Helvia Zeus CA series is designed for the world of small-medium commercial au-
dio systems, both on 70V or 100V constant voltage lines, and low-impedance lines
from 4 to 16 ohm. It oers 1, 2 and 4 channels Class-D ampliers with 120W, 240W
and 350W RMS powers.
Each channel is independent and equipped with its own line transformer, there-
fore it is possible to choose between 70/100V or 4-16 ohm low-impedance for
each of them, oering maximum versatility according to the specic needs of
each zone.
Each channel is equipped, in addition to volume, Led VU-meter and clip indicator,
with gain adjustment on the rear panel. There is also an HPF lter with a cut-o
frequency at 400Hz. Both inputs and outputs are balanced with XLR connectors;
all power outs are with Phoenix (Europlug) connection. The versions with 1 and 2
channels are also equipped with DC 24V auxiliary power input for any emergency
purposes.
Helvia paid high attention to safety, reliability and duration over time of these
ampliers. Each channel is equipped with muting system at power on, signal lim-

iter, thermal protection and current limitation. The cooling system with fan speed
controlled by internal temperature, is also reinforced thanks to the 19” 2U Rack
standard size that increases the thermal dissipation.
The quality is not only based on the accurate selection of active and passive com-
ponents, but also on the quality of raw materials used for line transformers, and
in the use of digital processing to oer stability, reliability and high-level sound
performance.

1. AC Power Connector and Fuse
ZEUS CA series ampliers are designed to operate at 230V - 50/60Hz. Check that
the socket to which the amplier is connected provides this voltage before plug-
ging the power cord (included) and turning on the unit.
Note: If you happen to lose the AC line-cord, always use a three-pin
plug with a ground pin. The wire correspondence is as follow:
Cable Pin International
Brown Live L
Blue Neutral N
Yellow/Green Earth
ZEUS CA Series
Multipurpose Power Amplifiers

ATTENTION: Always connect the earth! Pay attention to your safety!
Before taking into operation for the first time, the installation has to
be approved by an expert.
In case of fuse burn, to prevent the risk of re and damaging the unit, please use
only T10AL-250V (5x20mm) fuses. Before replacing the fuse, make sure the unit
turned o and disconnected from the AC outlet.
2. DC +24V Power Input
These ampliers can also be powered by DC 24V. This function is very useful in
those installations where an auxiliary power line is provided at 24V which, in the
case of blackout or other, powers the audio system mainly for emergency mes-
sages.
WARNING: When these amplifiers are powered by DC 24V, the
current consumption ranges from 6A up to 40A. Please take into
consideration this data when choose power cables thickness and pay
attention to the polarity of the terminals of this connector.
3. Output Connectors
1 2 3 4 5
Each channel has a 5-pole Phoenix (Europlug) connector for connecting to loud-
speakers.
• 1. It is the output positive pole for constant voltage lines at 100V.
• 2. It is the output positive pole for constant voltage lines at 70V.
• 3. It is the output positive pole for low-impedance speaker systems from 4 to
16ohms.
• 4. Output ground to be used as negative pole for both 70/100V lines and
4-46ohm systems.
• 5. Same as pin 4.
4. Channel Output Connector
Each channel has one balanced male XLR connector, which accepts an XLR-F con-
nector to almost any type of equipment with a balanced or unbalanced line-level
input.

5. Channel Input Connector
Each channel has one balanced female XLR connector, which accepts an XLR
plug from almost any type of equipment with a balanced or unbalanced line level
output.
6. High-Pass Filter
This 2-position switch, when in ON position, activates an high-pass lter with cut-
o frequency set to 400Hz.
It is useful in case of sound systems with subwoofers, of to reduce the bass-fre-
quency response in case of speakers with limited broadband (e.g. ceiling or
column speakers for vocal announcement only, etc.)
7. Channel Gain
This trimmer allows you to adjust the sensitivity of the input signal so that you al-
ways have an adequate margin (Headroom) between the nominal level of a signal
and the maximum level that the amplier can handle correctly before saturation
occurs with consequent signal reduction.
6. AUDIO CONNECTIONS
You will need XLR cables for the connections to the amplier. See the picture be-
low that shows the internal wiring of these cables. Be sure to use only high-quality
cables.
Balanced use of XLR connectors
1= Ground/Shield
2= Hot (+)
3= Cold (-)
INPUT OUTPUT
In case of unbalanced use Pins 1 and 3 will be jumped
You can, of course, also connect unbalanced equipment to balanced inputs. Use
either mono and stereo jack, making sure ring and collar are connected together
(or pins 1 & 3 in the case of XLR connectors).
7. RACK MOUNTING AND DIMENSIONS
Use four screws and washers to mount the amplier to the equipment rack rails.

3. PANORAMICA DEL PRODOTTO
La serie Zeus CA di Helvia è progettata per il mondo degli impianti audio com-
merciali di piccole e medie dimensioni, sia su linee a tensione costante da 70V o
100V, sia su linee a bassa impedenza da 4 a 16 ohm. Ore amplicatori in classe-D
a 1, 2 e 4 canali con potenze di 120W, 240W e 350W RMS.
Ogni canale è indipendente e dotato di un proprio trasformatore di linea, pertan-
to è possibile scegliere tra 70/100V o 4-16 ohm a bassa impedenza per ciascuno
di essi, orendo la massima versatilità in base alle esigenze speciche di ogni
zona.
Ogni canale è dotato, oltre che di volume, Vu-meter a Led e indicatore di clip, di
regolazione del gain sul pannello posteriore. È presente anche un ltro HPF con
frequenza di taglio a 400Hz. Entrambi gli ingressi e le uscite sono bilanciati con
connettori XLR; tutte le uscite di alimentazione sono dotate di connessione Phoe-
nix (Europlug). Le versioni a 1 e 2 canali sono inoltre dotate di ingresso di alimen-
tazione ausiliaria a 24V per eventuali sistemi di emergenza.
Helvia ha prestato grande attenzione alla sicurezza, all’adabilità e alla durata nel
tempo di questi amplicatori. Ogni canale è dotato di sistema di muting all’ac-
censione, limitatore di segnale, protezione termica e limitazione di corrente. Il
