Operation
All or some of the input sockets may have
active sources simultaneously connected to
them. The selector switch selects the input to
be amplified.
o
Once the external cables are connected
to the unit, ensure the master ON/OFF
switch is in the OFF position.
The master ON/OFF switch is on the
base of the lower compartment, near the
mains socket on the unit. You will have to
kneel on the floor at the back of the unit
to access the switch.
o
Plug the mains plug into a mains outlet.
o
Switch the master ON/OFF switch to ON.
The LEDs on the front and rear of the
amplifier will glow red. This indicates the
unit is in Standby mode. In this mode a
small current is drawn from the mains
supply, but the unit will not drive the
loudspeakers.
o
Press the mode switch once to switch
between Standby and ON modes.
The mode switch is a small pressure
switch accessed when standing at the
front of the unit. It is located under the
bottom lip of the top compartment.
When the amplifier has been switched to ON,
the LEDs on the front and rear will glow green.
The amplifier is now ready to drive your
loudspeakers.
It is recommended that the unit be switched
to Standby when not in use.
It is safer to turn the mains power off when not
using the dm78 or dm88 monoblock
amplifiers for extended periods. However the
amplifier may be left on in the Standby mode
for periods between active use. If you wish to
turn the mains power off, the amplifier has a
minimal warm up period.
