It can provide 24 extra B-inputs to the mix (S48 DOWN, S23 UP).
+For live applications try using MIX-B to feed a secondary set of speakers. These could be sidefills, or more spectacularly, the rearward portion of a quadraphonic sound system.
There is no SOLO provision for MIX-B. However, you can audition it by selecting only MIX-B (S83) in the monitor sourcing matrix.
+If MIX-B is assigned to the main mix (S48 DOWN), do not listen to MIX-B (S83) and the main mix (S82) simultaneously. That way you’ll be monitoring MIX-B twice over, and what you hear won’t correspond with what’s going down to tape.
6.3 Monitoring
Fig. 6.4: Monitoring
Though most of you will want to audition the main mix most of the time there are exceptions. These include PFL/SOLO, and 2-TRACK PLAYBACK. The SOURCING matrix (S82 to S85, see fig. 6.4) allows you to monitor the main mix, the MIX-B and two external sources marked 2-track and EXTERNAL. The master meters follow whatever source is being auditioned. The meters won’t make much sense if more than one source is selected!
EXTERNAL could be “normalled” to a HiFi pre-amp, allowing you to monitor extra sources such as vinyl, cassette, CD, etc.
Altering what goes into the control room’s monitors does not affect the signal from the main recording outputs. Just as well, or every time you wanted to do a quick SOLO during a mix, you’d have to start again!
