2.4.1 Top
This control uses our award-winning
'Varislope'
lift circuit where the lift is a nearly
flat "shelf" at low settings and as the control is
advanced it accentuates the higher
frequencies, resulting in a peak of 20dB at
10kHz (with gain set at 36 or 44dB).
2.4.2 Mid
A very broad lift peaking at either 800Hz or
2.5kHz depending on the position of the Mid
lift frequency selector switch. The maximum
lift available is 15dB.
2.4.3 Bass
Another 'Varislope' curve, where the lift starts
off quite high (2kHz) and the lower
frequencies gradually rise as the control is
advanced, giving a peak of 17dB at 50 Hz
when turned to maximum.
2.5 +48V
This switch will apply phantom power to the mic-in
sockets when in the down position.
2.6 Phase reverse
These switches will invert the phase of the signal in
the corresponding channel when in the down position.
