Once the desired meter characteristic has been chosen, proper scale labelling may be
ensured by removing the appropriate scale from the backing paper and applying it to the
recess provided between the two meters.
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 1-11: Brightness Control
A miniature flat-bladed screwdriver inserted into the hole next to the BRIGHTNESS symbol
should be turned clockwise to increase the brightness or anti-clockwise to decrease it.
PHASE Meter
The five-segment LED phase meter indicates the average phase correlation
between the left and right channels of the currently selected stereo audio
source. It is labelled in both degrees of phase shift and amount of correlation.
The phase meter is an “output” meter, reflecting exactly what is being heard
from the loudspeakers including any front panel signal modifiers that are
active.
A monophonic signal fed to both channels of the selected Source will have
a correlation of 1.0, while inverting one such channel – making it perfectly
out of phase – gives a correlation of -1.0. True stereo signals will produce a
fluctuating phase correlation.
Fig 1-12: Phase Meter Display
An interesting situation arises when only one channel of a stereo source 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 and 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
