Quad 44 Control Unit and Quad 405 Amplifier
This specialist Quad 44 Control Unit and Quad 405 Amplifier have come to us via a part exchange and come with a 3 month warranty.
Both items have been tested and are in full working order.
These units are in good cosmetic condition, apart from a few minor marks (please see images).
This Quad 44 Control Unit and Quad 405 Amplifier come with power cord included only. Please note that they do not include original packaging, but have been professionally packaged to ensure safe delivery to your door.
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 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 amplifier 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 unit, when compared at identical levels.
This is true for all inputs when used with their specified source impedances and within their 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.
It is extremely unlikely that the unit will become outdated, since any future developments in programme source or circuit technology can readily be accommodated simply by changing input modules.
The Quad 405 is a two channel power amplifier designed for domestic and professional use employing current dumping which eliminates many transistor problems.
The amplifier can be used with the 33 control unit or similar high quality pre-amplifier.
The high power output makes it suitable for use with many of today's high quality loudspeakers and provides opportunity for farther loudspeaker engineering development with less emphasis on efficiency.
The external design continues the Quad tradition of practical simplicity which has won prizes and worldwide acclaim on previous models.
A combination of mouldings and extrusions is used to produce a unit which is strong and pleasing both to the eye and the touch.
Not all loudspeakers can safely accept the full output power of the Quad 405, and the amplifier is provided with a power limiter which is fitted internally for use in such cases.
The Quad electrostatic loudspeaker can be used safely with the power limiter in.
