1 pcs AC power cord
1 Owner's Manual
1 pcs Spare fuse, 10.0 AT slow-blow 5x20mm (120V AC)

Connecting the AW 250 DMB-R

Connecting to mains

Check that the mains voltage printed on the rear panel of the amplifier corresponds with
the line voltage in the territory were you intend to use your amplifier.

How to avoid damages

A good operating practice is to turn off all equipment before any connections or
disconnection’s are made. Do not under any circumstances connect or disconnect
equipment when power is turned on. If you insist on connecting or disconnecting while
power is turned on, you should be aware that the design of the RCA plug generates a
large transient when inserting the plug. This could damage both the speakers and the
amplifier.

The rear panel

The rear panel of the Ampliwire AW 250 DMB is equipped with two sets of RCA input
sockets, marked + and -, and one XLR female socket, for each channel.

Single-ended (RCA) input and operation

Upon arrival, the amplifier is set for single-ended use with a shorting plug in the negative
RCA input.This will short the negative (-) input of the amplifier to ground. With shorting
plugs in position, the amplifier is ready to be connected in a normal way with a single
ended preamplifier.
