Example 1: Using the matrix in a live theater performance
System example: Sound reinforcement for live theatre

- Here, we assume a stage production which also includes live musicians
in the pit. All speech from the stage is sent to groups 1 and 2. The musicians'
performance is routed to groups 3 and 4. Stereo mikes are placed to catch
ambient audience response and are routed to groups 5 and 6 (but these are,
naturally, not routed to the front-of-house speakers). Prerecorded effects
are cued from a pair of DAT players routed to groups 7 and 8.
- We need, in addition to the stereo front-of-house mix: a stereo OB
mix for the local radio station, a mono lobby feed for latecomers to the
performance, and a dressing-room feed to cue performers off-stage.
- For the OB mix, we need to add the audience response (groups 5 and
6) to all the other groups. Matrix 1 becomes the L channel of the OB, and
Matrix 2 becomes the R channel. All odd groups are therefore sent to Matrix
1, and all even groups to Matrix 2.
- The lobby feed will need a boost to the "live" inputs (the
performers and musicians) compared to the front-of-house mix. Some audience
response is also useful here. Since this is a mono feed, all groups are
now sent to Matrix 3.

performers and musicians) compared to the front-of-house mix. Some audience
response is also useful here. Since this is a mono feed, all groups are
now sent to Matrix 3.
- Without sacrificing any grouping facilities or AUX SENDs, the M2000
has therefore provided an additional four mixes which meet a wide variety
of needs. The location of the matrix controls means no separate sub-mixer
operator is necessary - one operator can control all of these mixes, as
well as the front-of-house mix.
Example 2: Using the matrix to drive different speaker/amplifier stacks
- Another use for the matrix might be to drive different stacks distributed
throughout an auditorium. The relative volumes of different groups of signals
can be adjusted here to compensate for system characteristics, as well
as the acoustic characteristics of the venue.
Example 3: Using the matrix for foldback
- On stage, four different foldback mixes can be provided for the performers,
based on the group mixes. Of course, this does not give the full monitoring
flexibility provided by the YAMAHA series of monitor mixing consoles, but
for smaller situations, this can often be a useful feature, especially
when the all AUX SENDs are routed to effect units.
- Even though the M2000 is not primarily a recording console, the matrix
can be used to set up four different foldback mixes for performers in the
studio.
