1. IMPORTANT NOTE

Congratulations! You are the owner of a carefully designed and manufactured equipment. We thank you for
trusting on us and choosing our amplifier eLPA.
In order to obtain maximum operability 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 must 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 type of intervention and/or connection-disconnection 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 200Vpp.
The output cabling should be connected by a qualified technician. Otherwise only use pre-made flexible
cables.
There are no user or 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

eLPA series amplifiers offers the classical and acknowledged professional reliability of Ecler amplifiers with
a new aesthetic style and at an affordable price. The range consists of 4 stereo models of 350, 650, 950 and 1400
WRMS per channel over 4Ω. All models are 2 rack units high and are based on a robust chassis. Thanks to their
oversize power supply, the amplifiers can work comfortably at loads of 4 Ω.
eLPA series includes balanced inputs via XLR3 connectors. eLPA2-350 model also includes a ¼" jack,
and non-balanced inputs via RCA connectors. Their outputs offer complete versatility, thanks to the dual format
used: connectors of the safety terminal type with a normalized distance and Speakon
include an electronic limiter system to prevent clipping due to signal saturation. eLPA2-350 also includes a practical
cut filter or switchable crossover, which permits a single amplifier to provide the low and high signals of a two-way
mono loudspeaker system (with one eLPA amplifier on each channel for a stereo configuration).

2.1. Main features:

• Efficient system of progressive ventilation with a flow adaptable to the internal temperature of the amplifier.
Air is taken in at the rear and throws it out at the front panel
• The rotary input attenuation controls are easily accessible on the front panel.
• Indicators for power-on indicators (POWER ON), signal presence (SIGNAL), clipping (CLIP), and activation
of protections (PROTECT).
• Efficient system of protections against short-circuits, overheating and the presence of a continuous signal,
to prevent damage to the amplifier itself and/or to the loudspeakers connected to it.
• Integrated anticlip circuit (clipping or saturation of the signal) which is permanently activated.
Operating mode selector: STEREO, PARALLEL and BRIDGE.
Input sensitivity selector.
• Symmetrical inputs via XLR3 connectors.eLPA2-350 model also includes a ¼" jack type and asymmetrical
inputs via RCA connectors.
• Outputs amplified with terminal-type connectors and Speakon
Operation at 8 and 4Ω, or 8Ω in bridge mode.
Warranty: 3 years.
