Configuring the Amp

Configuring Amp Wiring & Bridge Mode

From the Amp Wiring Setup screen (see 

Figure 13

), input wiring can be configured. Here 

you can configure an input to feed multiple outputs (referred to as "Y'ing" the signal).
Bridge mono operation can also be configured from this screen. Bridging a pair of amplifier 

outputs will increase the power and voltage available at the output.

To configure input wiring and/or bridge mode:

1� 

From the Home screen, press the 

MENU

 button.

2� 

Select the “Configure Amplifier” option from the menu using the 

ENCODER

. 

3� 

Select the "Amp Wiring" option from the menu. 

4� 

Select the desired options for your application, making selections with the 

ENCODER

. 

5� 

When done, select "Done" at the bottom of the screen.

Available input options:

• 

Y 1+2

• 

Y 2+3*

• 

Y 3+4*

Available output options:

• 

Bridge 1+2

• 

Bridge 3+4*

For information on configuring signal routing and bridge mode settings in Audio Architect, see 

"Configuring Amp Wiring & Output Modes in 

Audio Architect" on page 36

.

*

Channel 3 and 4 options available in 4-channel CDi DriveCore models only.
