bk av125.7 Manual De Usuario

 
Generally in a home theater application, volume level is controlled by the A/V surround processor. In a system for 
use with the AV125.7 or AV125.5, adjustment of the volume level must performed using the external 
preamplifier/processor.  
 

The AV125.7 and AV125.5 allow signal patch cables (interconnects) to be sourced from either balanced or 
unbalanced line level preamplifier/processor outputs. A switch is used to configure a PAIR of AMPLIFIER 
CHANNELS for use with either balanced (XLR) or RCA unbalanced preamplifier/processor line outputs.  
 

XLR (BALANCED)

RCA (UNBALANCED)

 

There are seven balanced input connectors on an AV125.7 and five on an AV125.5. These connectors accept 
balanced line level output from the preamplifier’s balanced output connectors.
