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 HSA2-400.
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=30 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.

2. INTRODUCTION

The HSA2-400 is a stereo amplifier with both high and low impedance outputs, offering the
proven professional reliability of Ecler amplifiers at an affordable price. It uses very high-performance
technology, auto standby and convection cooling, with height of 2 rack units.
Equipped with balanced inputs on XLR3 and Euroblock connectors and Euroblock output
connectors. It has an electronic limitation system to avoid signal saturation as well as a thermal
protection.

2.1. Main features

- Easily accessible input attenuation controls on the front panel may be locked with Ecler
exclusive system.
- REMOTE ports to remote control the volume of each channel using WPm series wallpanels (0-
10VDC)
- Switchable auto standby circuit (energy saving mode when there is no input signal)
- Signal presence (SP), clipping (CLIP) and thermal protection (TH) indicators.
- Built-in, always active anticlip circuit
- Switchable subsonic filter, 40Hz 18dB/oct slope
- Operating mode selector: STEREO, MONO - BRIDGE
- Balanced inputs via XLR3 and Euroblock connectors
- Outputs on Euroblock connectors
- Operating at low impedance (8/4/2.66Ω) and high impedance (70/100 V, for speakers with high-
impedance transformer)
- Accepts 8, 4 or 2.6Ω loads (1, 2 or 3 speakers (8Ω) in parallel) when operating at low
impedance
