6. The treble FREQ control gives continuous adjustment of the frequency range that the treble
equaliser acts on from 1K to 20K.
7. The treble BELL switch converts the treble equaliser from traditional MIDAS shelving re-
sponse to full parametric operation.
8. The HI MID (dual concentric top) control gives continuous adjustment of boost and cut from +
15dB to - 15dB with a 0dB centre detent.
9. The hi mid WIDTH (dual concentric bottom) control gives continuous adjustment of band-
width from 0.1 to 2 octaves with a 0.5 octave centre detent.
10. The hi mid FREQ control gives continuous adjustment of the frequency range that the hi mid
equaliser acts on from 400Hz to 8K.
11. The EQ switch connects the equaliser in the input channel signal path and is under automation
control.
12. The LO MID (dual concentric top) control gives continuous adjustment of boost and cut from
+ 15dB to - 15dB with a 0dB centre detent.
13. The lo mid WIDTH (dual concentric bottom) control gives continuous adjustment of band-
width from 0.1 to 2 octaves with a 0.5 octave centre detent.
14. The lo mid FREQ control gives continuous adjustment of the frequency range that the lo mid
equaliser acts on from 100Hz to 2K.
14. The INSERT PRE EQ arranges the input channel signal to pass through the insert point
before the equaliser when activated and after the insert point when not activated.
15. The BASS (dual concentric top) control gives continuous adjustment of boost and cut from +
15dB to - 15dB with a 0dB centre detent.
16. The bass WIDTH (dual concentric bottom) control gives continuous adjustment of bandwidth
from 0.1 to 2 octaves with a 0.5 octave centre detent. This only operates when the BELL switch
is activated.
17. The bass FREQ control gives continuous adjustment of the frequency range that the bass
equaliser acts on from 20Hz to 400Hz.
18. The bass BELL switch converts the bass equaliser from traditional MIDAS shelving response
to full parametric operation.
19. The mono AUX controls (1 to 16) give continuous adjustment of the level sent from the input
channel to the aux busses. The level adjustment is from + 6dB to off.
20. The mono aux ON switches connect signals from the input channel to the mono aux busses
and are under automation control.
