84.3. Front panel controlsThe 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 sequencebegins. 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 inprotection mode.Once the amplifier is turned on and the startup is complete, the unit is available for normal operation.The front panel knobs (one per channel) allow to independently adjust the maximum output volume of eachamplifier channel. Moreover, EclerNet Manager application allows the DSP processing management (volume,phase, equalization, compression, delays, etc.) of each channel independently (SINGLE mode) or by pairs(BRIDGE & PARALLEL modes) and the Ethernet remote management, individually or by groups of channels and /or amplifiers. Please refer to the EclerNet Manager software manual for more information.Note: NZA amplifiers are setup with the following factory default parameters: Channels in SINGLE mode Inputs directly linked to the outputs (1 to 1, 2 to 2, etc.). Channel gain selector: 26 dB Channel Volume: 0 dB Crossover filters, EQ, compressor and delay deactivated (off)In this way, it’s possible to directly use the amp (without DSP processing or adjustments made throughEclerNet Manager) as a classic multichannel amplifier.In PARALLEL & BRIDGE modes, the maximum output level for each pair of channels can only be set fromthe first of the two knobs of each pair (CHANNEL 1 for the 1 & 2 pair, Channel 3 for the 3 & 4 pair and Channel 5for the 5 & 6 pair).Remote control ports also allow the volume adjustment of each amplifier channel (or pair of channels) froma potentiometer or another external hardware device, the maximum volume being determined by the position of thefront rotary control for each channel.In the device packaging, you’ll find a bag with clear caps to be inserted on the front panel knobs. Theyprotect the input attenuation settings from unsolicited tampering. Once inserted, you must use a flatheadscrewdriver or a similar tool to remove them.5. CLEANINGThe front panel should not be cleaned with dissolvent or abrasive substances because silk-printing couldbe damaged. To clean it, use a soft cloth slightly wet with water and neutral liquid soap; dry it with a clean cloth. Becareful that water never gets into the amplifier through the holes of the front panel.
