Wi SERIES - Professional stereo amplifiers

4 - Description

4.1 - Front panel

[1] - Mounting brackets

Allow you to insert your amplifier into 19" (482 mm)

racks.

[2] - Cooling vents

Wi series amplifiers (apart from the Wi640) are

equipped with two fans located at the rear.

The air flow goes from the rear to the front and

lowers the temperature of internal components.

Never obstruct these vents and clean them on a

regular basis to make sure your device benefits from

the longest possible lifespan.

[3] - Power Button

Activates the device.

[4] - Signal LEDs

These green and yellow LEDs light up when an

incoming signal is detected.

[5] - LED Clip

Lights up when the clip threshold has been reached,

to indicate the input is saturated and the outgoing

signal distorted.

Adjust the output level of your source to go back to

adequate sound levels and prevent serious damages

to your speakers and amplifier. The sound quality

will be highly improved as well.

Note : Wi amplifiers feature 2 identical

channels (1 and 2), the description below

only refers to one channel for legibility

concerns.

[6] - On LED

This blue LED lights up when the amplifier is

connected to an electrical outlet and the power

switch positioned onto ON.

[7] - Protect LED

This LED lights up to indicate the channel is in

protection mode, the output signal is interrupted by

an internal relay. The protection mode is activated

when the channel is overheating or a serious

problem has been detected. Its aim is to protect the

speakers connected to the channel in default.

Usually, this LED briefly lights up upon activation of

your device but should light off quite slowly. This is

to protect your speakers against current peaks when

your amplifier is initialising.

[8] - Input attenuator

Each channel features an input attenuator allowing

you to limit the incoming signal level.

This attenuator features 21 notches. On its left, it

attenuates the incoming signal by 80dB, on its right,

the signal is not attenuated and the amplifier works

at full power. When activating the "mono bridge"

mode, attenuator 1 only will affect the sound level,

whereas each attenuator adjusts the sound level of

the corresponding channel in "Parallel" mode.
