Operating Instructions
• 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 situated 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).
• Plug the mains plug into a mains outlet.
• Switch the master ON/OFF switch to ON. The LEDs on the front and rear of the
amplifier will glow red. This indicates that 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.
•
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 dm38. However the
amplifier may be left on in the standby mode for prolonged periods. If you wish to
turn the mains power off, the amplifier has a very minimal warm up period.
