adjustable with the center knobs up to ±15 dB.
HMF: Semi-parametric constant-Q equalizer (Q = 0.7). The center fre-

else the signal path is routed internally.
The signal is always available on the INSERT SEND jack socket, re-

ers (refer to section 3.1.2) to be pre-EQ or post-EQ.

Outputs to the mono auxiliary busses 1...6. The left- and right-channel
(pre- or post-fader) input signals are summed to a mono signal and can
be mixed to the desired AUX bus with the concentric potentiometers;
the knobs are the level controls for the odd-numbered AUX busses (1,
3, 5), the outer rings for the even-numbered AUX busses (2, 4, 6).
