What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Quad 34

 The Quad 34 provides the serious music listener with ererything necessary for thr 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 bushbutton 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 reverbration 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.
