Description: Line-level preamplifier with optional phono stage. Inputs: 3 pairs balanced (XLR), 5 pairs single-ended (RCA, optional), 2 pairs phono (XLR or RCA), 2 Controller/DC cable connectors, ground terminal. Outputs: 2 pairs balanced (XLR), 2 pairs single-ended (RCA), 1 pair record-out (XLR), 2 pairs record-out (RCA). Controller connectors: IEC AC mains receptacle, ground terminal, 2 Controller/DC cable connectors, three 3.5mm mini-jacks (for IR input, trigger out, trigger in), 3 Mark Levinson Link communications connectors, 6-pin RJ-11 RS-232 port, two 8-pin RJ-45 control ports (PHASTLink;r-compatible). Maximum voltage gain: 0, 6, 12, or 18dB (line stage); 40, 60dB (optional phono stage). Volume control range: 80.0dB. Gain resolution: 0.1dB steps above 23.0 on display (-57dB), 1.0dB steps below 23.0 on display (-57dB). Input overload: 2V on XLR, 1V on RCA (gain set to +18dB); 4V on XLR, 2V on RCA (gain set to +12dB); 8V on XLR, 4V on RCA (gain set to +6dB); 16V on XLR, 8V on RCA (gain set to 0dB). Frequency response: 10Hz-40kHz, ±0.1dB. Input impedance: 100k ohms. Output impedance: less than 10 ohms on XLR, less than 20 ohms on RCA. Maximum output (main outputs): 16V on XLR, 8V on RCA. THD+noise: less than 0.001%. Crosstalk: better than -120dB, any input to any output, input unterminated; better than -140dB, input terminated. Residual noise: 20Hz-20kHz; better than -120dBV, input terminated. Mains voltage: 100V, 120V, 220V, 230V, or 240VAC at 50 or 60Hz (factory-set).
