4 Input Pre Amplifier (1984-90)
Features tilt control and switchable filters
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 pushbutton, 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 engineers concepts.
It 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 with the widest possible variety of programme.

Smaller brother of 44 still outdoes many modern upmarket preamps. Good for vinyl.
