LED indicatorsStereo output:Mono output:Bridged Mono output:Standby/OnSwitches the unit between Standby mode (indicated by dim power LED)and On (indicated by bright power LED). Standby mode is a low powermode where the power consumption is less than 10 Watts. The unitshould be left in Standby mode when not in use.When the 840W is switched out of Standby mode it will automaticallycheck for faults and allow the power amplifier stages to stabilise beforeun-muting the speaker outputs.Note: The protection LEDs will flash whilst this check is being done.OutputIndicates that the Left or Right output is active. The LED (light-emittingdiode) is on for an active output, off for inactive (i.e. muted).ProtectionIf this LED is constantly on the 840W has detected a fault on either theLeft or Right channel and is protecting itself.ClippingThis LED indicates that the 840W has detected that either the Left orRight channel is being overdriven or clipped.Clipping distortion is caused at high volume levels when the outputsignal attempts to go outside the maximum voltage that the connectedpre-amplifier can provide, causing the tops of the signal to flatten off.When the 840W detects clipping this LED will briefly flash. If the clippingreaches a dangerous amount that could damage the amplifier orattached speakers the unit will then go into protection.BridgedThis LED indicates that the 840W is being used in Bridged mode. (TheMono LED will also be illuminated.)MonoThis LED indicates that the 840W is being used in a Mono mode.BridgedClippingOutputStandby / On MonoProtectionLeft RightClippingOutput Protectionazur 840WClass XD Power Amplifier6Front panel controls1212 3 4 2 3 45 66543ClippingBridgedClippingOutputStandby / On MonoProtectionLeft RightClippingOutput Protectionazur 840WClass XD Power AmplifierBridged MonoBridgedClippingOutputStandby / On MonoProtectionLeft RightClippingOutput Protectionazur 840WClass XD Power AmplifierBridged MonoBridgedClippingOutputStandby / On MonoProtectionLeft RightClippingOutput Protectionazur 840WClass XD Power AmplifierBridged Mono
