11.13.4. Zone feeds
Send independent relay feeds to additional locations such as the foyer, dressing rooms, cry room,
balcony and so on. You can use the groups to adjust the balance to suit the destination, for example
to boost the orchestra against the vocals. Feed the output through an EQ to tune the speaker for
acoustics.
11.13.5. Delay Fill speakers
Use the matrix to feed additional fill speakers for distributing the sound more evenly around a large
venue, e.g. centre fill, stage front fills, under balcony or rear fills, or ‘mix island’ delay tower on
festivals. To aid intelligibility for the nearby listeners without moving their focus from the stage, the
send should be delayed using an in-line delay processor. As a rule of thumb, delay 1ms per foot
difference between the listener and the fill and the listener and the main speakers. Now add a few
milliseconds ‘Haas effect’ delay so the listeners hear the main speakers slightly before the fill. Keep
the fill level about 10dB or so below the main PA sound at that location. It may help intelligibility to
boost the vocals above the instruments in the fills, and to use an EQ to cut the extreme LF and HF
frequencies.
11.13.6. Hearing assist
It is a growing requirement that venues provide a hard-of-hearing inductive loop, IR or wireless
broadcast for the hearing impaired audience. The matrix is ideal for this application as you can
combine a stereo LR mix into mono, add groups to help vocal intelligibility, patch in an external
ambience source, and add processing such as EQ and limiters which may be needed.
11.13.7. Additional monitor mixes
You could use the matrix to create some additional monitor mixes when you run out of auxes, this time
made up from a mix of the groups; LR and external input. The LR could be used to create a general
overall balance, and then the groups added according to musician preference. Groups could be routed
from ‘me only’ channels associated with each musician, or traditionally grouped sources. The musician
could get a balance from, say the overall stereo mix, drums, brass, keyboards, ‘me only’ and
ambience, a very quick way of mixing.
11.13.8. Combining two consoles into a single PA
In a festival situation you may have a support band wishing to patch their own console. One way to do
this is to feed the PA from a pair of matrices, and then use EXT inputs to combine the external console
with the main LR mix.
