DESCRIPTION
400 W RMS power amplifier for professional audio applications.
Its mechanical and electronic design are based on the criteria of functionality, toughness and reliability
required in any professional sound application. Its standard sizes (standard 19", 3U) allow it to be linked
to other elements in the UDE range or others, such as music sources, etc…. making up a homogeneous
compact unit with reasonable space-saving. Its surround housing is protected by a special anticorrosion
treatment.
The most innovative features of this unit are:
- Controlled power-up
The system limits the power crest absorbed by the power supply mains which takes place when the
amplifier is powered up. In this way it prevents damage and other trouble, such as the activation of
magnetothermal protection breakers or the blowing of fuses in the electrical panel, which are typical in
other high-power units.
- Forced horizontal ventilation system
This makes it possible to mount the EP-400TMV amplifier on a rack using accessory WX-3, with
maximum space optimisation.
- Acoustic correction device (ACD) build-in, protected against accidental manipulations.
- Automatic test device
As an option, it is possible to incorporate in the booster amplifier an automatic self checking unit (thanks
to module WX-106), and interconnect the booster amplifier with the monitoring unit SA-106 allowing
monitoring management and as well, if necessary, automatic switching of the faulty amplifier on the hot
standby one. When monitoring board WX-106 detects a failure, the "ON" signalising led located on the
front panel is blinking.

GENERAL CHARACTERISTICS
AMPLIFIER SECTION:
- Electronic protection against output short-circuits.
- Overheating detector. A safety device is triggered off in the event of overheating caused by
ventilator clogging. This status is indicated by "ON / OFF" blinking signalising lamp. When
temperature conditions revert to normal, the device switches off automatically.
- Volume control.
- Acoustic correction device (ACD).
This unit allows an equalisation for each booster amplifier according to the acoustic requirements
for each zone, in order to improve the sound reproduction. Protection against accidental
manipulations.
INDICATORS:
- On/off pilot light / Failure indication (blinking).
- Modulation pilot light.
POWER SUPPLY:
230 VAC 50/60 Hz
OPTIONAL FUNCTION
Automatic monitoring (module WX-106).
