The Analog Inputs come
from your turntables or CD
players. The Digital Inputs
come from the Virtual Decks in the Scratch
LIVE
software.
If the number for A
1
or A
2
is illuminated, the
Input has been selected by the Scratch
LIVE
software
as the vinyl emulation input for
Deck One
. If the
number for A
3
or A
4
is illuminated, the Input has
been selected by Scratch
LIVE
as the vinyl emulation
input for
Deck Two
. The backlit number is a reminder that this
source
may be a control signal
and not audio. You may select a
control input and use it as a normal analog input at any time
without de-selecting it for control in Scratch
LIVE
, but remember
that if you are playing a control record or CD,
you will hear the
control signal
.
See Control source and Phono sensitivity on page 32.
GAIN
These “trim” controls adjust the selected input to match other
inputs. These controls have a built-in Limiter that prevents the
signal from clipping regardless of the Gain setting. If increas
-
ing the Gain does not increase the signal level, then the signal is
already at maximum and the Limiter is controlling the signal to
prevent clipping. The Gain range is +15 dB to off.
PAN
These controls pan the signal between the Left and Right outputs.
HIGH / MID / LOW EQ
The control range is
OFF
to
+6
dB. These use 2
nd
-order (12 dB
per octave), Linkwitz-Riley,
Accelerated Slope
™ filters. The Low-
Mid crosspoint is 300 Hz. The Mid-High crosspoint is 4 kHz.
Kill switches provide instant-off for each control. The
skull lights red and the band is off when its Kill switch is pressed.
When the switch is released, the EQ goes back to the setting of
its EQ control. These switches may be set to momentary or toggle
operation within the Scratch
LIVE
software.

latch kill switches
on page 32.
