Quad 44 Pre Amplifier

Quad have always shown an originality in the design of their products as well as a dedication to their underlying philosophy of “the closest approach to the original sound”. Our Quad 44 pre amplifier is in good fully working condition with some minor blemishes on the unit, but nothing that affects the operation or sound quality on offer. The unit will be professionally packaged and comes with manual plus our regular 3 month warranty.
Quad Say….
If everything were perfect, a control unit would consist of a volume control and a programme selector switch. Unfortunately, this is not the case. Today’s music listener is faced with two major problems, how to ensure that his choice from the myriad range of pickup cartridges, tape recorders, radio tuners and microphones is correctly terminated by his amplifier; (a recent but by no means exhaustive guide lists 165 stereo pickups, 162 cassette decks, 44 open reel tape recorders, 115 radio tuners, 190 microphones, to say nothing of add-on equalisers, expanders, noise suppressors, etc); and how to cope with the problems of loudspeaker/room and programme/room interactions which become increasingly apparent with the steady improvement in the technical quality of programme material.
The Quad 44 has five inputs, Disc, Tape 1 and 2, Radio and Auxiliary, which will terminate correctly virtually every applicable programme source available now and in the foreseeable future. All five inputs are interchangeable, so that any combination of inputs can be obtained, and options such as moving coil pickup, or microphone inputs can be included.
The Quad 44 has tone controls, consisting of Filter, Bass and Tilt which enable the listener to correct for those acoustic problems which are amenable to frequency response shaping. Used intelligently these controls can improve the results obtained from almost any programme.
The performance of the Quad 44 meets the simple Quad criterion, that programme fed through the unit shall suffer no audible degradation, in other words, with the filter switch in the Cancel position there shall be no audible difference between the programme at the input· to and output from the Quad 44, when compared at identical levels. This is true for all inputs when used with their specified source impedances and within their specified input signal limits.
The Quad 44 will sound no better, or worse than the programme fed into it.
Construction and inherent reliability continue in the Quad tradition and reflect care in both design and workmanship. While there should be no need to remove the cover of the Quad 44, except when changing input modules, it is worthwhile to look inside just to see how high fidelity equipment should be manufactured.
It is extremely unlikely that the Quad 44 will be out-dated, since any future developments in programme source or circuit technology can readily be accommodated simply by changing input modules.
Servicing is very simple and quick since all the active circuitry is carried on plug-in modules which are readily interchangeable.
As with previous Quad pre-amplifiers great care has been taken to ensure that the probability of interference from external sources is reduced to a minimum.
