Line Inputs
Discrete Class A circuitry from input to output (unless Tube stage In),
Gain Range: -20dB to +20dB,
Maximum Input level: +26dBu,
Frequency Response: 10Hz to 40KHz, +0, -0.5dB,
Distortion: 0.007% @ 1KHz, +4dBu @ 0dB gain,
Distortion (THD + Noise): 0.025%, 10Hz to 40KHz,
Noise: -94dBu, 22Hz to 22KHz, @ 0dB gain at input and output.
Compressor
Threshold Range: -20dB to +10dB,
Ratio Range: 2:1 to 20:1,
Attack: 1ms (“Fast”), 8ms (“Slow”),
Release: 200ms (“Fast”), 2s (“Slow”),
Knee: “Hard” and “Soft” settings,
Gain Make-Up: 0dB to 20dB
Equaliser
LF: +/-15dB @ 80Hz, shelving,
Mid: +/-15dB, swept 150Hz to 7KHz, Q = 0.7,
HF: +/-15dB @ 12KHz, shelving,
“Pre” and “Sidechain” (Compressor) switches.
Output Gain
Gain Range: +/-20dB
Output
Maximum Level: +22dBu (2Kohm load), +26dBu (10Kohm load),
Tube Stage
Typical Distortion: 1% to 10%, depending on “Drive” level, predominately
second harmonic,
Noise: -88dBu (22Hz to 22KHz), output gain @ 0dB.
Metering
Tube “Drive” LEDs: Variable intensity over 10dB level range, typically corresponding
to 1% to 5% THD.
Tube “Peak” LEDs: Dependant on level and drive, typically corresponding to 10%
THD.
Output “Peak” LEDs: +19dBu on output.
VU Meter: Switchable to Channel A or B, Input or Ouput, and Gain Reduction.
Nominal calibration: 0VU = +4dBu.
+10dB switch calibration: 0VU = +14dBu
Power Requirements:
Internally set to 230V 50Hz or 115V 60Hz operation,
Detachable IEC power cord,
Power consumption 32VA.
