Front Panel Controls; Cleaning - Ecler NXA4-80 Notice D'utilisation

4.3. Front panel controls

The front panel includes a series of knobs and a on/off button.
The equipment can be locally switched on by holding down the POWER key until the startup sequence
begins. Shutdown also requires holding down the same key during a brief period.
The POWER key has an integrated LED that lights up in orange when the amplifier is in standby mode
(STANDBY), in green during operation (ON), and in red during the startup sequence or when the amplifier is in
protection mode.
After turning on and once the boot sequence completed, the device is available for use in normal
conditions.
Each front panel LEVEL knob (4 or 6, depending on the model) can be linked to the volume control of one
or more audio inputs or one or more audio outputs of the unit. The linking, like the other device setup settings, is
made from the EclerNet Manager application. See the EclerNet Manager manual for more information.
Moreover, the EclerNet Manager application allows the DSP processing management (volume, phase, EQ,
compression, delay, customised input mixes for each output channel, priority or DUCKER function, etc..) for each
channel, each channel being used independently (SINGLE) or in pairs (BRIDGE, PARALLEL modes) and remotely
managed individually or by groups of channels and / or amplifiers from a remote Ethernet location.
In BRIDGE and PARALLEL modes, the output level control of each channel pair from a front LEVEL knob
is done using the first channel of the pair only (CHANNEL 1 for 1 & 2, CHANNEL 3 for 3 & 4 and Channel 5 for 5 &
6).
GPI ports also allow to remote control the input or output volume from a potentiometer or another external
hardware device. Remember that the final level of each amplifier channel or output volume is determined by the sum
of values of:

its front rotary control (if it has one assigned)

its channel fader (in EclerNet Manager)

its GPI remote control port (if it has one associated with its volume control)

5. CLEANING

The front panel should not be cleaned with dissolvent or abrasive substances because silk-printing could
be damaged. To clean it, use a soft cloth slightly wet with water and neutral liquid soap; dry it with a clean cloth. Be
careful that water never gets into the amplifier through the holes of the front panel.
