DESCRIPTION OF FRONT PANEL CONTROLS
1. POWER SWITCH - This switch power the unit on and off
2. POWER LIGHT - This light is illuminated when the unit is powered on.
3. AVG,M/S,IND - These toggle switches add additional control for stereo linking and M/S modes. When
they are both in the down position, the UnFairchild can behave as two mono compressors. When the left
toggle is in the up position, the left and right signals are blended together and sent to both channels for
“Averaged” stereo linking (more about this on pg. 11). When the right toggle is in the up or “M/S” position
the feed forward signal is converted to M/S so you can do M/S compression on FF or blended side chain
signals. (More about this on pg. 12). The “SIDE CHAIN INSERT” toggle switches on the UnFairchild must
be turned on for these features to function.
4. FB/FF - These rotary switches control the blend between Feedback and Feed Forward signals going to
the side chain inputs. When the control is fully counterclockwise the side chain input will receive 100%
Feedback signal. When the control is turned fully clockwise the side chain input will receive 100% feed
forward signal. When the controls are in the 12 O’clock positions, the side chain input will receive equal
amounts of Feedback and Feed forward signals. The numbers indicate a difference in volume. Each
step of the rotary switch adds 2dB of difference in volume. For example, the “4” position in the clockwise
direction indicates that the “FF” signal will be 4 dB louder than the “FB” signal. The “SIDE CHAIN INSERT”
toggle switches on the UnFairchild must be turned on for these features to function.
5. HP FREQ - This rotary switch sets the high pass frequency for the side chain signal. In the fully coun-
terclockwise position there is no high pass filtering happening. As the knob is turned clockwise the high
pass frequency will get increasingly higher. The filter is 12dB/oct Butterworth filter at the frequencies in-
dicated by the marking on the panel. The “SIDE CHAIN INSERT” toggle switches on the UnFairchild must
be turned on for these features to function.
