Description: Solid-state stereo preamplifier. Phono inputs: MM & MC. High-level inputs: 5. Separate tape control. Ability for 1 external loop. Frequency response: 10Hz–20kHz ±0.1dB. RIAA accuracy: 0.1dB or better. Input impedance: adjustable (100k ohms standard) (phono), 10k ohms (high-level). Input capacitance (phono): 150pF. Input overload: 160mV (MM), 10mV (MC), 2V (line). Distortion 0.01% or better. Maximum output voltage: 18V rms. Output impedance 50 ohms in active, variable in straight wire with maximum of 10k at lowest volume. S/N ratio MM: 82dB A-weighted. MC: 78dB A-weighted (5mV reference). High level: 100dB A-weighted (active), unmeasurable (straight wire). Power supply: remote.
Dimensions: 19" W by 2" H by 7" deep (plus external power supply transformer, approximately 4.5" W by 3.5" H by 4.5" D). Weight: 5 lbs (estimated).
