What are the specs for the Audio Research SP-5?

Frequency Response:

High level sections: ±.25 dB 20 Hz to 20 kHz. -3 dB points,1 Hz and 100 kHz. Magnetic phono: ±.5 dB of RIAA, 20 Hz to 20 kHz. Optional moving coil pre-preamp (MCP-1) -3 dB points, 1 Hz and 100 kHz.

Distortion:

Harmonic distortion: Less than 0.005% at 2 V RMS output (IHF load). Intermodulation distortion: Less than 0.005% at 2 V RMS output (IHF load, SMPTE method). THD and IMD decreases with decreasing output.

Noise and Hum:

High level inputs, more than 90 dB below 2 V RMS output. Magnetic phono input, less than 1 µV equivalent input noise with 1 Kohms input (RIAA weighted). Typically 80 dB below 10 mV input at 1 kHz.

Gain:

Magnetic phono input to tape output, 36 dB. Magnetic phono input to main output, 60 dB. High level inputs to main output, 24 dB.

Input Impedance:

50 Kohms (nominal, all inputs). Magnetic phono 50 Kohms 200 pF (capacitance value may be reduced to 50 pF minimum, or increased as necessary).

Output Impedance:

50 ohms, recommended minimum load for maximum audio quality, 10 Kohms.

Maximum Inputs:

High level inputs, esentially overload proof. Magnetic phono input, 150 mV RMS @ 1 kHz.

Rated Outputs:

Maximum output 10 V RMS (all outputs, IHF load).

Power Supplies:
