Insert/Return
The MMC 2 offers an Insert/Return point after the Input Trims to include external
processing equipment into the signal path.
Monitoring
Monitoring functions comprise a Speaker Management section, a Monitors selection
section and the Monitor Level fader.
1. Speaker Management
Each loudspeaker can be activated or deactivated by a dedicated switch, and each is
labeled with its respective loudspeaker position.
A Solo switch is placed underneath each speaker switch. To alleviate channel compar-
isons, a Solo-to-Center function allows for monitoring of each channel through the
center speaker. The Solo-to-Center function can only be activated if a speaker is previ-
ously switched to solo.
If a surround sound mix does include separate LFE subwoofer signals, the LFE-to-L/C/R
switch distributes an LFE signal (factory standard -10 dB level) to the L/C/R channels.
Two Operation Mode buttons are provided to change the MMC 2 confi guration from
stereo to multi-channel operation. For improved operational safety and to switch off all
monitoring functions other than L/R, the Stereo button must be pressed before starting
a stereo mastering job.
The Monitor section offers three mono functions: 1. Mono L/R, 2. Mono LS/RS (not
available in stereo mode), 3. Mono L t/o / R t/0 (not available in stereo mode).
2. Monitors
The Monitors section allows for selection of two stereo and two multichannel speaker
sets. Three different Dim levels (-10 dB, -20 dB and -30 dB) and a Mute switch can be
activated for the selected set.
