Sinclair Project 80

Description

The Project 80 is the ultimate in modular HiFi construction and gives you the choice from a range of 9 different modules for combining in a variety of ways to suit your requirements.

The Stereo 80 is a versatile pre-amp control unit designed to meet all domestic Hi-Fi requirements including tape monitoring, high sensitivity magnetic cartridge input, and of course individual slide controls on each channel for precise output matching.

By separating the FM tuner and stereo decoder, useful economies can be effected where stereo radio reception is not needed.

Two power amplifier, Z40 (18 watts RMS continuous into 4 ohms using 35V) and Z60 (25 watts RMS continuous into 8 ohms using 50V) are available with a choice of 3 different power supply units.

The PZ8 with it's virtually indestructible circuitry is particularly recommended.

For the final word in system building, the Active Filter Unit puts the finishing touch of quality to what are easily the world's most advanced Hi-Fi modules.
