Graphic Symbol Explanation
The lightning 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 liter ature
accompanying the appliance.
The lightning flashes printed next to the OUTPUT terminals of the amplifier are intended
to alert the user to the risk of hazardous energy. Output connectors that could pose a risk
are marked with the lightning flash. Do not touch output terminals while amplifier power is
on. Make all connections with amplifier turned off.
WARNING: To prevent fire or shock hazard, do not expose this equipment to rain or moisture.
IMPORTANT SAFETY INSTRUCTIONS
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8. Do not install near any heat sources such as radiator s, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has
two blades with one wider than the other. A grounding type plug has two blades and a third
grounding prong. The wide blade or the third prong are provided for your safety. If the provided
plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at the plugs, convenience
receptacles, and at the point where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Unplug the apparatus during lightening sorts or when unused for long periods of time.
13. Refer all servicing to qualified personnel. Servicing is required when the apparatus has been
damaged in any way, such as power supply cord or plug is damaged, liquid has been spilled or
objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does
not operate normally, or has been dropped.
14. Disconnecting from mains: Switching off the POWER switch all the functions and light indicators
of the amplifier will be stopped, but fully disconnecting the device from mains is done unplugging
the power cord from the mains input socket. For this reason, it always shall remain readily
operable.

1. IMPORTA NT NOTE
Congratulations! You are the owner of a carefully designed and manufactured equipment. We
thank you for trusting on us and choosing our amplifier eGPA.
In order to obtain maximum operativity and perfect functioning order, it is most important to carefully
read all considerations taken into account in this manual before connecting this amplifier.
We recommend our authorised Technical Services if any maintenance task should be needed so
that optimum operation shall be achieved.
1.1. Precautions
The amplifier should have an earth connection in good conditions (earth resistance, Rg=30Ω or
less). The environment m ust be dry and dustless. Do not expose the unit to rain or water splashes, and
do not place liquid containers or incandescent objects like candles on top of the unit. Do not obstruct the
ventilation shafts with any kind of material. In case there is some t ype of intervention and/or connectiondisconnection of the amplifier, it is most important to previously disconnect the mains power supply.
Do not manipulate the output terminals to the loudspeakers when the amplifier is switched on,
there are voltages up to 400Vpp. The output cabling should be connected by a qualified
technician. Otherwise only use pre-made flexible cables. There are no user serviceable parts
inside the amplifier.
Failure to do so may result in malfunction of the device and may even damage the device:
1. Avoid turning on the device without speakers connected to its outputs and without
setting the volume / gain controls to the minimum.
2. Always use shielded cables to make the connections between devices.
2. INTRODUCTION
The Ecler Essentials eGPA amplifier series offers the renowned professional reliability of Ecler
amplifiers at an affordable price. It consists of 4 models: with a power of 2 x 150W RMS @ 4Ω (eGPA2-
150), 4 x 150W RMS @ 4Ω (eGPA4-150), 8 x 150W RMS @ 4Ω (eGPA8
-150) and a last one with a
power of 2 x 310W RMS @ 4Ω (eGPA2
-300). All models use very high-performance technology, auto
standby and convection cooling, with a height of 1 rack unit.
Equipped with balanced inputs on Euroblock connectors. Outputs also feature Euroblock
connectors. It has an electronic limitation system to avoid signal saturation and a thermal protection, as
well as a protection system against overload.
2.1. Main features
- Easily accessible input attenuation controls on the front panel.
- Switchable auto standby circuit (energy saving mode when there is no input signal)
- Signal presence (SP), clipping (CLIP), protection against overload (PROT) and thermal
protection (TH) indicators.
- Built-in, always active ant ic lip c ircuit
- Operating mode selector: STEREO, MONO - BRIDGE
- Balanced inputs on Euroblock connectors
- Outputs on Euroblock connectors
- Accepts 8 or 4Ω loads (1 or 2 speakers (8Ω) in parallel)
