Connect the PIP-USP4-CN module to the amplifier

(

Note:

 These PIP cards only works with CTs 2-Channel 

models).
1.  Turn the PIP module upside down so the ribbon 

cable connectors located along the back edge on the 

underside of the module can be clearly seen.

2.  Add the supplied ribbon cable ferrite core to the end 

of the (B) cable.

3.  Attach the ribbon cables from the amplifier to the 

ribbon-cable connectors. The 20 pin cable (A) should 

connect to the connector further inside and away 

from the corner (AJ9) and the 18 pin cable should 

connect to the one closest to the corner (BJ5). Start 

by connecting cable B.

Important:

 Be careful when attaching the ribbon cable 

to the connector. Don’t pull cables out if they are short. 

Applying pressure to an improperly seated connector could 

cause the keying tabs, which ensure proper pin alignment, 

to break. Connecting the ribbon cables with improper pin 

alignment will likely result in damage to the PIP module.

4.  Set amplifier sensitivity to 26dB, by placing both 

sensitivity switches in the center position.

5.  The Bridge-Mono Mode is set via software, leave the 

Mode switch in Dual and set the attenuator knobs to 

full clockwise, wide open, for all the features of the 

USP4 to function correctly.

Mount the PIP module in the amplifier

1.  With both cables firmly attached, turn the PIP to an 

upright position. Verify that the cables run untwisted 

between the amplifier and the PIP module. For best 

fit, bend the cables up and roll in the cores between 

the two circuit boards of the PIP module.

2.  Insert the PIP module into the amplifier while taking 

care not to crimp, pinch or stretch the ribbon cables.

3.  Fasten the PIP module to the amplifier rear panel with 

the two supplied mounting screws. Be sure to use the 

supplied star-washers for a good ground connection.
