Solid State Preamp Reviews

Description: Solid-state preamplifier with one phono input (MM/MC switch-selectable), seven line-level inputs, two tape loops, one external processor loop, and IR remote control. Specifications: Frequency response: 20Hz–20kHz ±0.1dB (phono), 20Hz–20kHz ±0.1dB (line). Line-stage bandwidth: 6Hz–150kHz, —dB, into 10k ohms. Input impedance: user-adjustable, 47k ohms in parallel, with user-selectable capacitance, 220pF as supplied (phono MM), user-adjustable, 100 ohms as supplied (phono MC), 20–28k ohms (line). Output impedance: 316 ohms (main), 2150 ohms (tape-out). Phono stage gain: 38.5dB (MM), 58.5dB (MC). Phono Sensitivity: 6.0mV at 1kHz (MM), 0.6mV at 1kHz (MC) for 500mV out from tape-out sockets. Line stage gain: 23dB. Line Sensitivity: 45mV RMS for 500mV out. Maximum output level: 8V RMS, 20Hz–20kHz. Phono overload: 65mV RMS at 1kHz (MM), 6.5mV RMS at 1kHz (MC). THD+noise: 0.002% (MM), 0.009% (MC), 0.005% (line). S/N ratio (A-weighted): 87dB ref. 500mV output (MM phono), 80dB ref. 500mV output (MC phono), 94dB ref. 500mV output (line).
Dimensions: 17" W by 8.5" D by 3" H (preamplifier), 2.875" W by 7.5" D by 1.5" H (remote control).
Price: $800 ($650 without remote control and IR card) (1989); no longer available (2008). Approximate number of dealers: 450 (1989).
