Notes

A high power integrated stereo amplifier with flexible and comprehensive input/output options with a Direct switch which allows direct connection of sources to the power amp via only the volume control. Housed in a champagne gold or black metal case with output power of 120 watts RMS per channel into 8 ohms or 140 watts RMS per channel into 4 ohms. With a jack for headphones, RCA phono sockets for Phono1 (MM or MC), Phono2 (MM), CD, Tuner, Aux, for input/output Tape1, Tape2, terminals for 2 pairs of loudspeakers.

Features
- Quarter A and AVSS technologies offer high dynamic power coupled with pure Class A sound (up to 25 watts).
- FET phono section for low noise, low distortion and low colouration - gold-plated connectors. (Frequency response to IEC spec.)
- Moving coil input offers two sensitivities.
- Copper-plated chassis reduces distortion from electro-magnetic coupling in metalwork.
- Two tape monitoring circuits with Record Output Selector to listen to one source while recording another.
- Switchable audio muting and subsonic filtering.
- Relay controlled speaker switching between two pairs of speakers - substantial binding posts.
