Bridged Mono Output
The power output of the XPA 1002 can be effectively doubled by bridging the
output. Bridging allows power to be output in mono at 200 watts @ 8 ohms or
120 watts @ 16 ohms.
NOTE: The bridging instructions that follow apply only to the XPA 1002 model.
Minimum load impedance when bridging is 8 ohms.
To bridge the output channels refer to figure 8:
1. Unplug the IEC power cord from the power amplifier.
2. Wire the output as shown.
NOTE: The + terminal of Output channel 1 becomes the positive output terminal and
the + terminal of Output channel 2 becomes the negative output terminal.
3. Wire the input (balanced
Ñ
, or unbalanced
Ö
) as shown.
4. Connect the IEC power cord and power up the amplifier.
5. Adjust the input levels of channels 1 and 2 equally.
See the “XPA Input Level Adjustment:” on page 7 for more details.

NOTE: During bridged mono output the + output from output channel
1 becomes the positive terminal and the + output from output
channel 2 becomes the negative terminal.
