This diagram shows the basic mixer setup using the Audition bus to rec-

ord an interview with a telephone caller off-air, whilst playing music 

through stereo channel ST1. The interview could be recorded from the 
Audition out phono connectors or via the USB port as shown here. 

 

Notes: 

 

Ensure Audition buttons 
are pressed and audition 

lights are on for the off-

air channels 

 

Switch the CLF source for 

the caller to Audition. 
 

Select Audition to USB if 

recording to computer.  

 

The producer can monitor 

either the live program or 
the off-air interview using 

the CRM selection switch-

es.
