SPECIFICATIONS
Gain at 1kHz: 81dB of gain at 1kHz, balanced-in to balanced-out in Microphone Input Mode
Noise figure, rms A-weighted: <2dB
Noise figure, rms unweighted: <3dB, 20 kHz LPF bandwidth
EIN: <-130 dBu A-weighted, 150 Ohm resistive source
DC Current Draw: 130 mA
Frequency Response: -3dB <1Hz and >100 kHz
THD: <0.02% at 1 kHz
Input Impedance: 10K Ohms
Line Input Impedance: 20K Ohms
Mic Gain Control: Twelve-position switch provides from +13dB to +62dB of gain for the preamplifier circuit, as measured between the input and the before the output line driver.
Switched LF Shelving filter: -3dB break-frequency tunable from 22 Hz to 515 Hz; maximum reduction -20dB
Switched CurveShaper™ EQ: +3dB break-frequency tunable from 2.5 kHz to 30 kHz; HF gain adjustable from +0dB to +20dB; the slope of the HF filter varies interactively and directly with the Curve- Shaper™ frequency and gain settings.
XLR output maximum level into 600Ω load: +28 dBu, balanced; 0 dBu = 0.7746 V rms
XLR connectors polarity: Pin-1 is ground, pin-2 is high, pin-3 is low LED signal level indicators: The green LED snaps on at -20 dBu to indicate the presence of signal; the yellow LED snaps on at 0 dBu; the red LED snaps on at +24 dBu to warn of approaching signal overload.
