Note: The front panel is common for all models.
1: Analogue level controls: These function in both analogue input and network audio input mode.
2: Signal meters: These will show the level of the respective amplifier's output channel. The red LED in the
meter will illuminate when the limiter threshold has been reached and limiting is occurring.
3: Link LED: This indicates if the channel is linked to its immediate neighbour. If this is illuminated, the
attenuation control of the channel to the immediate right will not function as both channels are being fed
from the left hand channel. Linking is disabled in Network Audio mode and Link LEDs will be extinguished.
4: PROTECTION LED: If a condition exists, either internally or externally, that could cause damage to either
the amplifier or the speakers, the protection circuit will disengage the outputs and this LED will
illuminate/flash.
Typical conditions that could cause the protection to be triggered include very high frequency or
subsonic input signals, DC in the inputs, short-circuited outputs, or internal high temperatures.
The protection circuit can affect all channels or a 'channel pair' depending on the type of fault. This is
indicated by the combination of Protection LED illuminating and a corresponding message on the LCD. In
this way, it is possible for two channels (a channel pair) to remain functioning even though a fault has caused
the other channel pair to mute. A channel pair would be 1+2 or 3+4.
Temperature related faults will reset automatically if the unit has cooled sufficiently. Output short circuits
will require manual reset after clearing the fault (switching off at the mains switch and then on again after a
few seconds). Short circuits on either channel of a channel pair will only affect that channel pair.
5,6: BRIDGE pair LEDs: The channel pair LED will illuminate if these channels have been switched into
bridged (mono) mode. See page 11 for details of how to connect your speaker to a bridged channel pair,
and page 12 for how to enable bridge mode.
7: STBY LED: The
DX
amplifiers can be powered down leaving just the input circuitry and Dante network
audio card (if fitted) active. This LED illuminates when the power amplifier sections are turned OFF.
8: Power Switch: This double pole switch turns the amplifier fully off and isolates it from the mains supply.
