Connection and setup
Connect the rear IEC inlet (17) to the mains using the supplied mains lead (or an equivalent
approved type). Ensure that the mains voltage is correct and that the mains outlet is switched on.
Connect any line level audio inputs to the Aux input (12) on the rear panel using RCA leads.
Connect a microphone (if required) to the front panel jack input (10).
Further amplifiers can be connected from the rear Out RCA sockets (11).
The DM25 can be used either with 100V line or standard low impedance speakers.
Speaker connections are provided as spring terminals on the rear panel (13, 14, 15)
Next to the speaker connections is a spring terminal for FM Antenna (16)
This should be connected to the core of an antenna cable for good FM radio reception (if required)
NOTE: Do not connect a speaker output to the antenna by mistake. This may carry high voltage.
These 2 configurations cannot be used together, so it is important to decide which method will be
used at the start.
