Configuring the a 23 for Bridged Mono Operation

CONFIGURING THE A 23 FOR BRIDGED MONO OPERATION 6

In certain applications, you may require your A 23 to power a single 8 Ω speaker by using its bridged mono feature. In most instances, you won’t use the A 23 this way and you can skip this section.

What You’ll Need:

•One length of speaker wire with banana plugs, spade lugs, or bare wires

•One shielded balanced or unbalanced interconnect cable for each A 23 used in bridged mono

•One loudspeaker with an impedance of 8 Ω or higher

Before Connecting

Remove power to all the components in your audio system.

Set the A 23 Stereo - Mono Switch to its Mono (up) position.

To Connect: From the Source

1Plug one end of the interconnect cable into the Balanced or Unbalanced Right Channel & Mono Input jack on the A 23

2Plug the other end of this cable into the desired output channel on the preamplifier or surround controller.

3Do not make any connection to either Left Channel Input jack on the A 23.

To Connect: To the Speaker

4Insert the wire with the ridge or other marking into the red Right + (positive) speaker terminal on the A 23. (This is the positive speaker terminal in bridged mono.)

5Insert the wire without the ridge or other marking into the Left + (positive) speaker terminal on the A 23. (This is the negative speaker terminal in bridged mono.)

6Insert the wire with the ridge or other marking into the red + (positive) terminal on the speaker.

7Insert the wire without the ridge or

other marking into the black --	6 7
(negative) terminal on the speaker.

8 Do not make connections to either of the A 23's black speaker terminals.

YOU SHOULD KNOW

IMPORTANT! - Before Trying Bridged Mono

You should not connect a speaker with an impedance of less than 8 Ω to the A 23 when it is configured for bridged mono operation. Refer to Bridged Mono Operation in the Technically Speaking section for additional information about. Use the right channel Gain control to adjust level in the bridged mode.
