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 even more spectacular, 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!
