Extron electronic XTRA SERIES Bridged Mono Output, Bridging the Output of the XPA 1002 Series

Page 25

Bridged Mono Output

The power output of the XPA 1002 and XPA 1002 Plus can be effectively doubled by bridging the output. Bridging allows power to be output in mono at 200 watts at 8 ohms.

NOTES:

•The bridging instructions that follow apply only to the XPA 1002 series.

•The minimum load impedance when bridging is 8 ohms.

To bridge the output, follow the steps and refer to the diagram below:

1.Unplug the IEC power cord from the power amplifier.

2.Fully attenuate the potentiometer.

3.Wire the output as shown in the following diagram.

4.Wire the input as shown in the following diagram.

5.Connect the IEC power cord and power up the amplifier.

6.Adjust the input levels of channels 1 and 2 identically.

NOTE: See D (Attenuation) of Rear Panel Features and Operation on page 12 for more details.
