1 Standby/On	LED indicators
Switches the unit between Standby mode (indicated by dim power LED)	Stereo output:
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.

Mono output:

2Output

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).

3Protection

If this LED is constantly on the 840W has detected a fault on either the

Left or Right channel and is protecting itself.

4 Clipping Bridged Mono output:

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.

Clipping

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.

5Bridged

This LED indicates that the 840W is being used in Bridged mode. (The

Mono LED will also be illuminated.)

6Mono

This LED indicates that the 840W is being used in a Mono mode.
