QHW The Vinyl MM/MC Phono Preamp

• Discrete MC head input with BJT.  Low Rb to achieve very low noise floor when dealing with the tiny signal from lowest level MC cartridges.
• Discrete MM input. The excellent AE2270 amplifier will take input from MM cartridges.
• Component values in RIAA network have been carefully selected to achieve high precision among with tight tolerance components, like 0.1% 25 ppm thin film resistors.
• Flexibility. Selectable load to fit your tastes. Two independent inputs.

Nominal gain at 1 KHz

• MM: 42 dB
• MC low: 63 dB
• MC high: 69 dB

Maximum output level: 9 V RMS or more.

MM input impedance: 47 KOhm

MM input capacitance: adjustable from 47 pF to 617 pF.

MC input impedance: adjustable from 47 Ohms or less to 47 KOhms.

MC input capacitance: 150 pF.

Total harmonic distortion at 1 KHz, 2 V RMS output, 10 KOhms load (20 HZ – 20 KHz band):

• MM:  0,004 % or less.
• MC low:  0,007 % or less.

RIAA deviation 20 Hz – 20 KHz: less than ± 0,1 dB.

Residual noise: < 300 uV (MC input shorted).

Signal to noise ratio:

• MM: -84 dB or better (input shorted, referred to 2 V RMS).
• MM: -96 dB or better (input shorted, referred to maximum output).
• MC low: -78 dB or better (input shorted, referred to 2 V RMS).
• MC low: -90 dB or better (input shorted, referred to maximum output).

Crosstalk: < -96 dB (at 1 KHz referred to 2 V RMS output in other channel).

Power consumption: < 10 W

Power supply: output, 36 V DC, input 100 V – 240 V AC 50 – 60 Hz.
