[. . . ] CHANNEL PFL/PEAK LED When the PFL switch is pressed, the Pre-Fade signal is fed to the Control Room and headphones outputs, where it replaces the selected source. The PFL/AFL LED on the master section illuminates to warn that the monitor and the meters are now responding to the PFL/AFL selection and the PFL LED on the input channel lights to identify the active channel. This is a useful way of listening to any required input signal without interrupting the main mix, so that adjustments can be made or problems traced. When the PFL switch is released the LED on the channel serves as a PEAK indicator, to warn when an excessively high signal level is present in the channel. The signal is sampled at two points in the channel, PRE INSERT, (PRE HF/LF EQ if in the Channel path), and POST EQ. The Peak LED will illuminate approximately 4dB before clipping and therefore give warning of a possible overload even if the peaks are removed by external equipment plugged into the Insert. CHANNEL ON This switch routes the Channel signal to the Channel PAN control and then to the routing matrix. It is positioned post-fader to ensure minimum system noise when released, while leaving the pre- fade foldback sends enabled. Page 14 16. MIX & GROUPS 1-8 The input channel signal is routed to the main STEREO mix (MIX) or to the GROUPS as stereo pairs (1-2, 3-4, 56, 7-8) as selected by these switches. 17. CHANNEL FADER This long-throw fader determines the proportion of the channel in the mix and provides a clear visual indication of channel level. Normal operating position is at the 0 mark, providing 10dB of gain above that point if required. INPUT - MONITOR PATH 18. TAPE SEND & RETURN The TAPE SEND is normally fed from one of the 8 GROUP outputs. These are repeated across each 8 channels, e. g. Group 1 feeds Tape Sends 1, 9, 17 and Group 2 feeds Tape Sends 2, 10, 18 etc. When the DIRECT switch (8) is pressed the Tape Send receives only that channel output instead. The electronically balanced TAPE RETURN is the normal input to the MONITOR path but is swapped to the Channel path when CHANMNTR INPUT REV (7) is pressed. TAPE TRIM This centre-detented control provides -10dB to +20dB of gain trim on the Tape Return input. Note that the centre-detented position is the line-up point for +4dBu type Tape Machines. For matching -10dBV machines the control will need to be reset to about the 3 oclock position. AUXILIARY SENDS (see 12 a bove) The MONITOR path normally has a pre-fade Foldback (FB2) send, and two post-fade Auxiliary sends (AUX 3, 4) as described for the Channel path. AUX 3 & 4 may be switched to the Channel path by the CHAN switch if required. Page 15 21. AUXILIARIES TO CHANNEL FB2 and AUX 3 & 4 are normally in the Monitor path. Pressing CHAN routes AUX 3 & 4 to the Channel path, while FB2 remains unaltered. 22. MONITOR PAN The Monitor PAN control determines the position of the signal within the stereo image. Rotation fully anticlockwise feeds the signal solely to the Left mix buss, while rotation clockwise sweeps the image to the Right. 23. MONITOR FADER This rotary control determines the overall level of the Monitor signal path. Unity gain point is at approximately 7. 5 on the scale. 24. MONITOR PFL/PEAK LED When the PFL switch is pressed, the Pre-Fade signal is fed to the Control Room and headphones outputs, where it replaces the selected source.
