GAIN (F6)
comprises t w o
(left
and right) potmeters that adjust the level
of
the audio, and thus the balance.
m=
The
range of
the
potmeters
(gain)
is
-20
dB to
(approx.)
+5
dB.
If
the
potmeters are
turned fully anticlockwise the Sound Enhancer is adjust ‑
ed
for unity gain
(1:1).
The
pot. meters always operate in the
digital
domain. If the Sound Enhancer is adjusted
for unity gain only the first
LED

the LED bars will
light up.
The moment
the potmeters
pass the
position
-20 dB the LED
bar will display the gain setting.

INPUT (F7)
is a toggle action push button switch that alternately selects
the digital and analog input. The selected input is indicated by either
the
DIGITAL (F3) or ANALOG (F4) LED
being on.
In
order
to
avoid acci ‑
dental switching to another input, the button
m u s t
be pressed for
about a second before the switch is made.
m
MAXT.S. (F8)
is a toggle action, push button, switch that improves
(TS
= transient suppression) scratch suppression. The scratch effect
must be activated, only then can TS be
activated.
When TS is
on,
it is
indicated by an LED in the switch coming
on. MAX
T.S. should only be
used in
extreme situations, or
with
m o n o
signals, because its effect is
to virtually reduce stereo to mono. To compensate for this, MAX TS
can
be used in combination with the
stereo
enhancement effect. Max.
TS can be used for mono signals without any detrimental effect.
The next
g r o u p
comprises four yellow toggle action push button
switches. Each of these buttons contains an LED which comes on when
the switch is active.
mw
Q.N.I. (F9)
activates/de-activates
the Quantization Noise imaging effect.
m= FADE
(F10)
activates the fade effect
( w h e n
it is enabled, indicated by
the FADER LED being o n ) .
The button sequentially activates fade in and
fade out, so
care
should be taken when using it. During fade-out and
fade-in the
LED
indicator in
the fade button will flash.
