Quad 33 used
The Quad 33 selects and controls the radio tuners, gramophone pickup and tape recorder connected to it and feeds the loudspeakers via the power amplifier, providing for stereo, mono on either or both channels, from all inputs, plus monitoring and track selection facilities for tape.
Quad units may be used either free standing or mounted in a cabinet with plenty of scope for individual preference in layout.
The standard Quad system of mounting is used, requiring only a rectangular cut-out for which a template is provided.
The controls are comprehensive but simple and are logically grouped to facilitate selection and control of the programme.
The filter is essential with modern good quality speakers and helpful at any time.
It removes surface noise, tracing distortion and similar shortcomings in the upper frequency range of the recording or broadcast, and the two control filter system achieves this to a very fine degree without intruding unnecessarily into the harmonic range so essential for realistic reproduction.
