INPUT SENSITIVITY (Level to achieve full power):
With Pad Out...
Nominal input: 100 mV RMS
Minimum input: 9 mV(pre gain and master fully CW)
Maximum input: 3.0 V(maximum signal at input before
clipping occurs)
With Pad -10 dB in:
Nominal input: 315 mV RMS
Minimum input: 28 mV (pre gain and master fully CW)
Maximum input: 9 V (maximum signal at input before
clipping occurs)
EQUALIZATION:
Bright boost: + 8 dB @ 5 kHz
Contour: Special frequency compensation
Bass: ± 15 dB @ 30 Hz, Shelving type Eq
Mid : ± 15 dB @ 200 @ 2 kHz (Mid shift control determines
center frequency)
Mid Shift: 200 to 2 kHz
High: ±15 dB @ 8 kHz, Shelving type Eq
TUNER SEND:
Instrument level through a buffer
LINE OUT:
-∞ to -10 dB (for nominal input).
Level is dependent on level control setting and pre gain setting
EFFECTS LOOP:
Set for -10 dB (0.315 V RMS) with pre @ 5, Master @ 10
Controlled via footswitch, ground tip to defeat.
PREAMP OUTPUT:
1 V RMS nominal
