Standby/On
Switches the unit between Standby mode (indicated by dim power LED)
and On (indicated by bright power LED). Standby mode is a low power
mode where the power consumption is less than 10 Watts. The unit
should be left in Standby mode when not in use.
When the 840W is switched out of Standby mode it will automatically
check for faults and allow the power amplifier stages to stabilise before
un-muting the speaker outputs.
Note: The protection LEDs will flash whilst this check is being done.
Output
Indicates that the Left or Right output is active. The LED (light-emitting
diode) is on for an active output, off for inactive (i.e. muted).
Protection
If this LED is constantly on the 840W has detected a fault on either the
Left or Right channel and is protecting itself.
Clipping
This LED indicates that the 840W has detected that either the Left or
Right channel is being overdriven or clipped.
Clipping distortion is caused at high volume levels when the output
signal attempts to go outside the maximum voltage that the connected
pre-amplifier can provide, causing the tops of the signal to flatten off.
When the 840W detects clipping this LED will briefly flash. If the clipping
reaches a dangerous amount that could damage the amplifier or
attached speakers the unit will then go into protection.
Bridged
This LED indicates that the 840W is being used in Bridged mode. (The
Mono LED will also be illuminated.)
Mono
This LED indicates that the 840W is being used in a Mono mode.
