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 XPA20000.
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 XPA20000 amplifier have a power consumption of 1866 VA (at 1/8 of maximum power output, as
specified by regulation EN 55103-1). We recommend a 2.5mm
magnetothermic circuit breaker that can handle at least 32A@230VAC (these values are for one amplifier).
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 or serviceable parts inside the amplifier.

2. INTRODUCTION

High efficiency mosfet amplifier.
Ecler XPA Power Amplifier series offers the renowned professional reliability of all Ecler amplifiers at an
affordable price. The line consists of five models with power outputs of 300, 500, 700, 1100 and 1980 WRMS per
channel at 4Ω (1980 WMRS @ 4 ohms for XPA20000). Thanks to their oversized power supply, these amplifiers
can operate comfortably with 4Ω and even 2Ω loads.
XPA20000 amplifier features balanced input connections via XLR3. The outputs offer total versatility thanks
to secure connection posts with standardized separation and Speakon® sockets. An electronic limiting system for
avoiding signal overloads and a switchable subsonic and LPF filters are also on board.

2.1. Main features

- Highly effective progressive cooling system. Air flow rises as a function of amplifier temperature. "Front to
Back" cooling system takes air from the front and throws it out to the rear panel.
- Easily accessible input attenuation controls on the front panel may be locked with Ecler exclusive system.
- Indicators for Signal Present (SP), Clipping (CLIP) and activation of protection circuits (PROT).
- Effective protection systems against short-circuit, excessive temperature due to accidental blocking of air
flow or other circumstances, DC at the output... to protect the amplifier and loudspeakers.
- Built-in, switchable active anticlip circuit.
- Switchable subsonic filter, 30 Hz 18dB/oct slope.
- Switchable LPF filter, 150 Hz.
- Operating mode selector: STEREO, PARALLEL and BRIDGE.
- Input sensitivity selector (0.775 / 1 / 1.4V).
- Balanced inputs via XLR3.
- Outputs on connection posts and Speakon® connectors.
- Operation with 8, 4 and 2Ω or 4Ω in bridged mode.
- 2 years warranty.
