PRECAUTIONS

Important Safety Symbols

The above warning is located on the unit

• The lightening flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
• The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product

Important Safety Instructions

• Read these instructions
• Keep these instructions
• Heed all warning
• Follow all instructions

1. Water and Moisture
   The apparatus should be protected from moisture and rain and can not be used near water; for example near a bathtub, a kitchen sink, a swimming pool, etc.

2. Heat
   The apparatus should be located away from heat sources such as radiators, stoves or other appliances that produce heat

3. Ventilation

PRODUCT OVERVIEW

Helvia Zeus CA series is designed for the world of small-medium commercial audio systems, both on 70V or 100V constant voltage lines, and low-impedance lines from 4 to 16 ohm. It offers 1, 2 and 4 channels Class-D amplifiers with 120W, 240W and 350W RMS powers. Each channel is independent and equipped with its own line transformer, therefore it is possible to choose between 70/100V or 4-16 ohm low-impedance for each of them, offering maximum versatility according to the specific 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 filter with a cut-off 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 amplifiers. Each channel is equipped with muting system at power on, signal limiter, 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 components, but also on the quality of raw materials used for line transformers, and in the use of digital processing to offer stability, reliability and high-level sound performance.

Main Features

• 1, 2 and 4 channels from 120W to 350W each
• 70V – 100V and 4-16ohm operation
• 2U 19” Rack Standard for maximum heat dissipation
• High-quality components for maximum reliability
• 24VDC Auxiliary Power Supply for EMC purposes (only 1-Ch and 2-Ch models)
• Full protection system including signal limiter, thermal protection, and current limiting
• Variable-speed fans for quiet and efficient cooling

FRONT PANEL

1. Signal LED Bar (Green)
   This bar, present on all channels, lights up when the signal level ranges from -30dB to about 0dB. If these LEDs remain on, you might need to reduce the channel volume or reduce the incoming audio signal.

2. Clip LED (Red)
   This LED, present on all channels, lights up when the corresponding channel has an output overload. Some flashing may be normal but if these LEDs remain on for a long time, please reduce the input signal levels until the LEDs turn off.

3. Power LED
   The POWER indicator lits whenever power is ON.

4. Power Switch
   Press this switch to (1) position to turn the amplifier ON, and to (0) position to turn it OFF.

5. Volume Control
   This knob adjusts the volume of each channel.

6. Front Panel Ventilation Grid
   It allows constant ventilation inside the amplifier. When the amp works harder, the fan will speed up and expel more hot air. It is suggested not to obstruct this grill

REAR PANEL

AC Power Connector and Fuse
ZEUS CA series amplifiers are designed to operate at 230V – 50/60Hz. Check that the socket to which the amplifier is connected provides this voltage before plugging 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:

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 fire and damaging the unit, please use only T10AL-250V (5x20mm) fuses. Before replacing the fuse, make sure the unit turned off and disconnected from the AC outlet.

DC +24V Power Input
These amplifiers 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 messages.

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

Output Connectors

Each channel has a 5-pole Phoenix (Europlug) connector for connecting to loudspeakers.

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.

Channel Output Connector
Each channel has one balanced male XLR connector, which accepts an XLR-F connector to almost any type of equipment with a balanced or unbalanced line- level input.

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.

High-Pass Filter
This 2-position switch, when in ON position, activates an high-pass filter with cutoff frequency set to 400Hz. It is useful in case of sound systems with subwoofers, of to reduce the bass-frequency response in case of speakers with limited broadband (e.g. ceiling or column speakers for vocal announcement only, etc.)

Channel Gain
This trimmer allows you to adjust the sensitivity of the input signal so that you always have an adequate margin (Headroom) between the nominal level of a signal and the maximum level that the amplifier can handle correctly before saturation occurs with consequent signal reduction

AUDIO CONNECTIONS

You will need XLR cables for the connections to the amplifier. See the picture below that shows the internal wiring of these cables. Be sure to use only high-quality cables.

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).

RACK MOUNTING AND DIMENSIONS

Use four screws and washers to mount the amplifier to the equipment rack rails.  To use the amplifier outside a rack, attach the self-adhesive rubber feet to the bottom. In the applications where the rack assembly may be moved, we strongly recommend supporting the rear of the amplifier. Optional rack handles provide finger grips at each end, making lifting and setting into the rack more comfortable.
