Aiwa SA-C30 mini pre-amp

Stereo Pre-amplifier - Control Unit

Features:
RIAA deviation of ±0,2 dB (20 Hz - 20 kHz) and phono Signal-to-Noise of 87 dB
Low-noise transistors, used in the first stage, are combined with high gain ICs to reduce noise and improve stability. Carefully selected polypropylene capacitors and high-precision metal-film resistors are used as the RIAA elements for an RIAA deviation of less than ±0,2 dB over a frequency range of 20 Hz to 20 kHz, thereby yielding an extremely accurate frequency response. The maximum rated input of 200 mV (at 1 kHz) assures an ample margin for the input signals.

Two power supplied (plus and minus) with high-performance differential amplifier ICs.
A plus-minus dual power supply design is used for the high-performance differential amplifier ICs in the amplifier circuit. This allows a faithful amplification of the signals with a minimum of distortion.

A high-performance tone control circuit that is bypassed when the knobs are set at the center "0" position.
A low-cut filter suppresses noise components in the ultra-low-frequency range such as those generaated by a warped record.
With just a flick of the muting switch, the power output can be reduced to one-tenth of the set level.
The loudness switch enhances the low-frequencies when listening at low volumes.
