Power switch
The Delta 60 is turned on by depressing the power switch. The
small rectangular LED (light emitting diode) above the switch will glow
green. After several seconds you may hear a gentle click from inside the
amplifier. This indicates that the speaker protection relay has been released
and that the amplifier is ready for use. To turn the unit off depress the
power switch again so that it unlatches. The green LED, which indicates
that the dc power supplies within the amplifier are operating, will continue
to glow for a short time after the unit has been switched off as the internal
power supplies discharge.
Note
The Delta 60 will play music within seconds of switching on.
However, in common with other audiophile products, the internal circuits
take some time to stabilise fully and the very best sound quality may not be
obtained until the amplifier has had a reasonable time (possibly up to an
hour or two) to warm up.
Input selection
The Delta 60's five inputs are selected via 5 rectangular
buttons on the unit’s front panel. To select the input required depress the
appropriate input selector.
Volume control
The volume control is of a split type and allows you to
adjust the levels of the left and right channels for both loudspeakers
independently. Normally, the two halves of the control knob rotate
together as they are locked together by a friction clutch inside the volume
control itself. However, by holding the rear part of the control firmly with
the first finger and thumb of one hand, it is possible to alter the relative
position of the two parts of the knob and thus compensate for level
differences caused by the nature of the input signal or due to room
acoustics.
