6. The LO MID control gives continuous adjustment of left and right boost and cut from +15dB
to -15dB with a 0dB centre detent.
7. The lo mid FREQ control gives continuous adjustment of the frequency range that the lo mid
equalisers act on from 100Hz to 2K.
8. The lo mid WIDTH control gives continuous adjustment of the filter bandwidths from 0.3 to 2
octaves with 1 octave being the centre position.
9. The EQ switch connects the left and right equalisers in the input channel signal paths and is
under automation control.
10. The BASS control gives continuous adjustment of the left and right shelving filters boost and
cut from +15dB to -15dB with a 0dB centre detent.
11. The bass FREQ control gives continuous adjustment of the frequency range that the bass
equalisers act on from 20Hz to 200Hz.
12. The mono AUX controls (1 to 16) give continuous adjustment of the level sent from the input
channel to the aux busses. The signal is a mono sum of the left and right signals and the level
adjustment is from + 6dB to off.
13. The mono aux ON switches connect signals from the input channel to the mono aux busses
and are under automation control.
14. The mono aux PRE switches change the signal sent to the mono aux busses from post fader to
pre fader.
15. The ST AUX controls (1 to 8) give continuous adjustment of the level sent from the input
channel (post pan) to the stereo aux busses. The level adjustment is from + 6dB to off.
16. The stereo aux ON switches connect signals from the input channel to the stereo aux busses
and are under automation control.
17. The stereo aux PRE switches change the signal sent to the stereo aux busses from post fader
to pre fader whilst retaining the post pan stereo image.
18. The left and right PAN controls are used to place the input channel signals within a stereo
mix. As well as image placement, the controls can also adjust the image width from stereo
through mono to reverse stereo (left and right crossed over). The controls have a constant power
law i.e. -3dB at the centre position.
19. The INS switch connects the left and right input insert return signals to the input channel and
is under automation control.
20. The ST switch connects the input channel post fader signals to the stereo master buss via the
pan controls and is under automation control.
21. The MUTE switch mutes the input channel at all points except the insert send and pre insert/
eq direct output. This switch is under automation and auto mute group control.
