Description
Tubed, remote-controlled line preamplifier with six sets of balanced and unbalanced inputs, three sets of balanced and unbalanced outputs, and a unity-gain Processor input.
Tube complement: 6550C and 6H30P (power-supply regulation), four 6H30P (dual triodes).
Frequency response: 0.2Hz–200kHz, +0/–3dB, at rated output (balanced, 200k ohms load).
Maximum voltage gain, main output (single-ended or balanced input): 12dB, balanced output; 6dB, single-ended output.
Distortion: <0.01% at 2V RMS, balanced output.
Input impedance: 120k ohms balanced, 60k ohms single-ended.
Output impedance: 600 ohms balanced, 300 ohms single-ended main, 20k ohms minimum load and 2000pF maximum capacitance.
Output polarity: non-inverting.
Maximum input: 20V RMS maximum balanced, 10V RMS single-ended.
Rated output: 2V RMS (1V RMS single-ended) into 200k ohm balanced load (maximum balanced output capability is 30V RMS at <0.5% THD at 1kHz).
Noise: 1.7µV RMS residual IHF-weighted balanced noise output with volume control at “1” (109dB below 2V RMS output).
Power consumption: standby, 2W; full output, 130W.
