Concert FOH

A Front of House system for a large concert:
• Left/Center/Right FOH speakers made up of nine separate clusters.
• Mono mix that is added to a video signal and sent to the dressing rooms.
• The headliner's engineer insists on using his own mic preamp for the lead singer.
• There are several legacy effects to be patched in.
• The band wants to record everything (multitrack) and the band's engineer wants a board tape.
The LCR system uses three separate systems per channel (meaning 9 systems) to cover the audience area.
For each LCR channel, there is a subsystem covering near, midthrow and longthrow seats. The near system
for the center channel is aimed to cover the seats in the immediate front of the main floor seating area. The
other two channels of the center channel cover the middle and rear of the main floor seating area. There's
also a VLF system (subs) that need to be fed from their own mix.
Patch the lead singer's mike directly into the external mic preamp. Return the preamp to the lead vocal
channel's insert return. Use the output level control of the external preamp and the channel's meter to set
the level going into the UMX.96.
Use the matrix for the LCR near system and the mono mix. Let the system processor sort out the details of
the LCR system, but since there are so many crossover channels required, use the speaker manufacturer's
dedicated crossover at the amp racks and run the UMX.96 system processor in advanced routing mode (so
you don't need to deal with the abstraction of a crossover). You use the matrix to drive the system proces-
sor because you may need to reduce the separation between left and right while leaving the pan settings
alone at the operator's level. The other big plus for the matrix comes when you find that the mix sent to the
downstage front fill system needs to be considerably different than what you send to the rest of the house.
In the end, you end up creating a special group mix for the downstage fill system, while letting the LCR mix
handle the rest of the venue.
The VLF system is simply fed from an aux send. For convenience, route the aux send through the system pro-
cessor so that every control needed to balance the whole system is all in one place. You might also want to
make the master faders and the VLF system aux send part of the same VCA group so that you can have one
control to control the entire system.
Since the matrix is also driving the video system's audio, it's a simple matter of just remixing the LCR chan-
nels down to mono. If it turns out that you need something extra added, it's a simple task because of the
flexibility of the matrix.
The legacy FX require one or two aux sends each, depending on the input structure. At the output, they will
need either a channel or one of the stereo line inputs.
1. For mono devices (one in, one out): create an aux send, and connect the aux output to the device's line
input. Return the device to a channel. Engage the channel pad so that the input can handle a full-blown
line level signal
2. For stereo devices (one or two in, two out), create an aux send, and patch the device in to the aux out-
put and connect the device's outputs to one of the stereo line returns. For two-in-two-out devices, just
create a stereo aux send.
Finally there's the recording. If it's just a board mix, create your own using the Matrix.
If it's multitrack, then connect the recorder's analog inputs to each channel's direct output configured to pre
or post channel DSP as desired.
