NOTE; that each of the treble, bass and balance controls has a “click stop” in the dead centre

(12 o’clock) position, to enable a flat frequency response and even channel balance to be set

accurately and repeatably.

Treble control

The treble control progressively cuts treble signals when turned anti-cldckwise and boosts them

when turned clockwise. A “flat” frequency response is obtained when the control is set

accurately to the 12 o’clock position. It is unusual to have to use this control at its extremes, i.e.

outside the 9 o’clock or the 3 o’clock positions.

Bass control

The bass control progressively cuts bass signals when turned anti-clockwise and boosts them

when turned clockwise. Again, the flattest response is obtained at the 12 o’clock position. The

bass control in the A60+ amplifier has been designed to operate at frequencies about an octave

lower than normally encountered in other amplifiers. Because of this, a significant amount of

boost or cut may be employed to compensate for loudspeaker deficiencies without affecting the

lower middle frequencies.

Balance control

The balance control is used to move the stereo sound image to the left or right. It can be used

to compensate for imbalances in room acoustics or input signals.

Headphones socket

The headphones socket accepts any headphones fitted with a standard Vi inch stereo jack plug.

The headphones may mute the loudspeakers, or not, as required (see page 2).
