Speaker Outputs

To avoid damage to the a15.3, make sure it is NOT plugged into an AC outlet while connecting up or disconnecting speaker wire to the speaker outputs. The a15.3 has one pair of speaker outputs on the back labeled + R (right speaker) and L + (left speaker).

Use a suitable pair of speaker cables for connecting the speakers.

Consult with your dealer if you need advice.

Connect the right speaker to the R connectors and the left speaker to the L connectors.

Pay careful attention to match the positive (red or +) connector on your speaker to the positive (+) terminal on the a15.3.

Likewise, match the negative (black or -) speaker connector to the negative (black or -) terminal on back of the a15.3. This will insure your loudspeakers are playing in phase.

Connecting to the Mains - Plugging In

Check that the on/off button on front of the a15.3 is in the off position. Push the plug

(IEC line socket) of the power cable supplied with the a15.3 into the socket (AC IN) on back of the unit. Make sure it is pressed in firmly. Plug the other end of the power cable into an AC wall outlet.
