Product Description
Features:
* Switchable boost / cut ranges of ±6 or ±15 dB * Electronically balanced / unbalanced inputs * Servo balanced / unbalanced inputs * RF filtered inputs & outputs * XLR, Barrier Strip, and 1/4" TRS connectors * -12dB / +12dB input gain range * 18 dB/octave 40Hz Bessel low-cut filter * Chassis / signal ground lift capability * Internal power supply transformer * Power-off hardwire relay bypass with 2-second power-up delay Specifications: Inputs Connectors: 1/4" TRS, female XLR (pin 2 hot), and barrier terminal strip Type: Electronically balanced/unbalanced, RF filtered Impedance: Balanced 40k?, unbalanced 20k? Max Input Level: >+21dBu balanced or unbalanced CMRR: >40dB, typically >55dB at 1kHz Outputs Connectors: 1/4" TRS, male XLR (pin 2 hot), and barrier terminal strip Type: Impedancebalanced/ unbalanced, RF filtered Impedance: Balanced 200?, unbalanced 100? Max Output Level: >+21dBu balanced/unbalanced into 2k? or greater >+18dBm balanced/unbalanced (into 600?) System Performance Bandwidth: 20Hz to 20kHz, +0.5/-1dB Frequency Response: <10Hz to >50kHz, +0.5/-3dB +/-15dB range +/-6dB range Dynamic Range: 109db 115db Signal-to-Noise: 90db 97db THD+Noise: <0.005% Interchannel Crosstalk: <-80dB, 20Hz to 20kHz Function Switches EQ Bypass: Bypasses the graphic equalizer section in the signal path Low Cut (recessed): Activates the 40Hz 18dB/octave Bessel high-pass filter Range (recessed): Selects either +/- 6dB or +/- 15dB slider boost/cut range Indicators Output Level: 4-LED bar graph (Green, Green, Yellow, Red) at -10, 0, +10, and +18dBu EQ Bypass: 1 LED: red Clip: 1 LED: red Low Cut: 1 LED: red +/-6dB: 1 LED: yellow +/-15dB: 1 LED: red Power Supply Operating Voltage: 100VAC 50/60Hz, 120VAC 60Hz, 230VAC 50/60Hz Power Consumption: 1215 24W; 1231 24W Mains Connection: IEC receptacle Physical Dimensions: 1215: 3.5" H X 19" W X 7.9" D (8.9cm x 48.3cm x 20.1cm) 1231: 5.25" H X 19" W X 7.9" D (13.4cm x 48.3cm x 20.1cm)
