Brightness Control
The brightness of the bargraph meters and all other front panel indicators may be adjusted
to suit user preference or to match similar units nearby.
Fig 2-8: Brightness Control
A miniature at-bladed screwdriver inserted into the hole marked BRIGHTNESS should be
turned clockwise to increase the brightness or anti-clockwise to decrease.
PHASE Meter
The ve-segment LED phase meter indicates the average phase correlation
between the two currently selected audio Sources. It is labelled in both
degrees of phase shift and amount of correlation. The phase meter is an
“output” meter, reecting exactly what is being heard from the loudspeakers
including any front panel signal Modiers that are active.
If both selected Sources carry the same signal, a correlation of 1.0 will result,
while inverting one channel – making it perfectly out of phase – gives a
correlation of -1.0. True stereo signals will produce a uctuating phase
correlation.
Fig 2-9: Phase Meter Display
An interesting situation arises when only one of the selected Sources is fed with signal. If
the unused channel is perfectly silent (as is possible in the case of a digital source) then
the phase correlation will average 0.0, but a small degree of crosstalk between the used an
unused channels (as is likely in the case of analogue sources) will allow the signal to self-
correlate and the meter will display an average correlation nearer 1.0.
BALANCE Control
The balance control is a centre-detented rotary
potentiometer allowing adjustment of the relative
balance between the left and right loudspeakers.
The control characteristic maintains a constant
overall power from the loudspeakers. turning the
balance control fully to the left increases the volume
of the left-hand loudspeaker by 6dB and attenuates
the right by 6dB, and vice-versa.
