Balance ControlThis merely adjusts the balance of the two channelsand after initial adjustment it should require no alterationfor normal listening unless a misbalanced recordingor broadcast is to be reproduced, which is unusual, orunless the position of the loudspeakers or theirenvironment is changed.Bass and Treble Controls (See page l6).The musical balance of a programme is carefullyadjusted during recording or broadcasting and adjustmentof the bass and treble controls should not normallybe necessary unless an inferior loudspeaker or the listeningenvironment produces some effect which needscorrection. Once set for a particular installation, therefore.these controls should be little used. Small deviationsof the bass control will affect very low notes only.Greater deviations aftect not only the very low notesto a greater extent but also the high bass notes. Thetreble control afiects brilliance.Loudspeaker PhasingIf, for any reason, there is any doubt about the wayin which the loudspeakers are connected (see page 6)their phasing may now be checked by playing a monodisc over both channels, when the sound should appearto emanate from a point midway between them. Ifthis is indefinite the connections to either of the loudspeakers,but not both, should be reversed. Correctlyconnected the speakers will give a definite centre soundsource accompanied by a more full bodied sound in thetenor and bass registers.Page Fifteen
