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 eHSA.
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 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 eHSA amplifier series offers the renowned professional reliability of Ecler
amplifiers at an affordable price. It consists of 2 models: one with a power of 2 x 150W RMS @ 70/100V,
high impedance (eHSA2-150) and a second one with a power of 4 x 150W RMS 70/100V, high
impedance (eHSA4-150). 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 anticlip circuit
- Operating mode selector: STEREO, MONO - BRIDGE
- Balanced inputs on Euroblock connectors
- Outputs on Euroblock connectors
- Accepts high impedance loads on 70/100V line
