SYSTEM PERFORMANCE
Frequency Response: Mic Input: 20 Hz to 50 kHz, +0/-1dB, 40 dB gain
Instrument Input: 30 Hz to 70 kHz, +0/-1dB, unity gain
THD + Noise: Mic In to Line Out: 0.25% typical at 0 dBu out, 1 kHz, 40 dB gain
Instrument In to Line Out: 0.2% typical at 0 dBu out, 1kHz, unity gain
Equivalent Input Noise: Typically > -123 dBu with a 150 Ω source load, 22 Hz to 22 kHz
Noise Floor: Mic Insert to Comp Output: <-93 dBu, unity gain, EQ flat and no gain reduction
Operating Temperature: 0º to 40º C (32º to 104º F)
PREAMP FUNCTION SWITCHES / CONTROLS
Instrument Input: Selects between microphone XLR input and front panel ¼” instrument input
+48V: Sends +48 VDC through 6.81 kΩ resistors to pins 2 and 3 of the microphone input
20 dB PAD: Attenuates the microphone input by 20 dB
Polarity Invert: Reverses pins 2 and 3 of the microphone input XLR
80 Hz Low Cut: Enables an 80 Hz, 12 dB/octave high-pass filter in the microphone and instrument signal path
GAIN Control Range: -∞ to +55 dB for Microphone Input
-∞ to +40 dB for Instrument Input
Post Tube Attenuation: -∞ to 0 dB
Peak Indicator: Illuminates RED when the Preamp is within 3 dB of clipping
