INSERT switch
This switch enables the rear-panel insert loop by inserting any device connected to the Send and Return
jacks into the signal path. The insertion point is post-tube, pre-EQ.
LOW control
This control varies the gain of the low frequency equalization; the gain range is -15 to +15 dB. The low
frequency filter is a shelving lowpass configuration with a knee frequency of 80 Hz.
MID control
This control varies the gain of the mid frequency equalization; the gain range is -15 to + 15 dB. The mid
frequency filter is a bandpass configuration with variable frequency and switchable bandwidth.
NARROW switch
This switch selects the bandwidth for the mid frequency filter. The default bandwidth is 1.5 octaves; with
the NARROW switch depressed, the bandwidth is 0.5 octaves.
