Aiwa AS-S30 amplifier

Stereo Integrated Amplifier

Fifteen big Watts per channel of honest-to-goodness high fidelity sound from a 2-stage differential SEEP-OCL integrated amplifier an incredibly compact 7,1 cm high by 21 cm wide. Yet, the A30 has plenty of room to accommodate up to 4 external components including tape, deck, tuner and record turntable.

Power output has been boosted by use of a new extra-stable power transformer with independent coils for power and preamplifier sections, and enlarged heat sinks aid in efficient heat dissipation.

For low noise and dynamic performance from high quality MM phono cartridges, the improved phono equalizer IC has boosted Signal-to-Noise Ratio to an excellent 82 dB, with very low 0,005% distortion at 1 kHz. RIAA equalization is a remarkably precise ±0,2 dB throughout the 20 to 20,000 Hz frequency range. For well-balanced listening at low output volumes a switchable loudness compensation circuit is provided.
