FORM FACTOR

One channel, multi-input, gain, filter, parametric equalizer with insert capability and internal power supply

• Inputs: Mic (balanced, XLR), MI (Musical Instrument; unbalanced, 1/4” TS)

• Gain control: +15dB to +7dB, 5dB steps

• Fine control: -5dB to +5dB, continuously variable

• Phase switch, Phantom power (P48) switch

• Filter — Second-order Butterworth active high-pass filter; 100Hz, flat, 40Hz

• Insert control: split parametric equalizer from preamplifier

• EQ section: four bands, fully parametric, continuously variable controls

• EQ IN switch

• Overload (OL) indicator: peak indication, preamplifier and equalizer

INPUT

Microphone: 1 kΩ balanced, >80dB CMRR, +17dBu max input before clipping

Insert In: 20 kΩ balanced bridging, >40dB CMRR, +21dBu max input before clipping

MI: 1 MΩ unbalanced, +8.5dBu maximum input before clipping
