Quad 34 Pre Amplifier

Peter Walker founded the Acoustical Manufacturing Co. in 1936, and since then all Quad products have displayed originality in design, and over the years, made a major contribution to the improvement of sound quality. Here we have a Quad 34 pre amplifier that is in good overall cosmetic condition but there are a couple of minor blemishes on the unit, but nothing that affects the operation or sound quality on offer. The unit will come supplied professionally packaged with our usual three month warranty.
Quad Say….
The Quad 34 provides the serious music listener with everything necessary for the full enjoyment of music from radio, disc, tape and compact disc and continues a process of evolution which began more than thirty years ago with the original Quad control unit.
Inputs are selected by pushbutton controlled solid state switches and all inputs are fully isolated so that one can switch from one to the other without turning down the volume control or switching off unwanted sources.
Filters, selected by push button, provide optimum characteristics to remove distortions inherent in the record playing system and leave more of the music.
The Tilt control changes the programme balance to compensate for the difference between the reverberation of the actual listening room and the recording engineer’s concepts. The tilt control is a highly sophisticated eight pole filter that is smooth in operation with no abrupt changes of response and no unwanted colouration.
The Bass control fulfils one of two functions: as an equaliser for use with small loudspeakers in the lift mode when it provides smooth progressive bass boost to compensate for the low frequency roll-off of small enclosures, and as correction for low frequency exaggeration due to floor or corner placement, in the step mode.
In short, the Quad 34 provides correct input matching and compensation for programme and room effects with excellent ergonomics. Everything necessary to obtain enjoyment from the widest possible variety of programme. The Quad 34 also incorporates those intangibles which existing Quad owners take for granted but can come as something of a pleasant surprise to those who have not dealt with a serious but friendly and helpful manufacturer before, intangibles which make ownership of Quad a pleasure which improves with time.
Correct disc input matching, both of impedance and sensitivity, and accurate RIAA equalisation. is essential for optimum results. The Quad 34 is supplied with two disc input modules, one to suit most moving magnet pickup cartridges with a load of 47k//220pF and sensitivity of 3mV, and one to suit most moving coil pickup cartridges with a load of 100Ω//22nF and sensitivity of 100µV. A range of modules is available to match pickup cartridges not covered by the two standard modules. When pickup and input are correctly matched, optimum performance is achieved with the signal from the cartridge positioned well above the noise threshold and well below the overload ceiling of the disc input.
