M/S Master

Control Elements

Output & VU section 

-10 dB

Use this push button to reduce 10 dB the sensitivity of the VU-meters. When the VU-meters‘ 
needle points at 0 db, it actually corresponds to -10 dBu and the maximum value is +15 dB. 
The sensitivity switch allows you to analyze very high level signals that would otherwise be 
beyond the range of a normal meter.

ACTIVE

Use the ACTIVE push button to switch on or off the processing electronics of the M/S Master. 
When switched off, input signals are forwarded directly to the outputs.

The ACTIVE push button accomplishes two very important tasks:

1.  A/B comparison between processed and unprocessed audio material.

2.  Switching  between  M/S  and  A/B  stereo  processing,  including  external  processing 

without the need of any recabling.  

Refer to the information on „Input and Output Electronics“ and „MID INSERT, SIDE INSERT“ 
on page 9.
