Q2 OPERA TION AND MAINTENANCE MANUAL 9601 76 This module contains the circuit for one group output and one matrix output. The signal path for the group signal is from the bus through the appropriate link depending upon which group the module is programmed to receive into the bus mixing amplifier . The signal then is fed to the balanced insert send ...

Q2 OPERA TION AND MAINTENANCE MANUAL 9601 78 The stereo module is very similar to the mono group output but of course the signal paths must be duplicated. There are two group output signal paths and two matrix sends which can selected pre or post fader . The matrix returns are fed to ganged pots and the matrix output is again duplicated to give a s ...

Q2 OPERA TION AND MAINTENANCE MANUAL 9601 79 Three group outputs are required on this module to give the required Left, Centre and Right outputs. The signal path for each of these outputs is as for the mono group output. The matrix output is mono and is fed from a mix of the LCR signals. The matrix returns are stereo capable and again foldback and ...

Q2 OPERA TION AND MAINTENANCE MANUAL 9601 83 The VCA master module contains two VCA group master faders and their associated cut switches. A reference voltage of -5V is fed to the faders and applied to ICs 12A and B where it is offset by a fraction of the original reference voltage. The output of the ICs is fed via an enable switch to the VCA group ...
