Program Channel Section
29. LEVEL
This knob adjusts the gain of the input signals
selected by the position of the source [30] switch. The
knob ranges from off, to +12 dB of gain at maximum.
Adjust this with your good eye on the program meter
[39], so the level is typically bouncing between the 0
and +6 LEDs.
30. SOURCE
This switch selects one of three possible input sources
for each program channel:
• FireWire: The signal coming in from your com-
puter via the internal FireWire interface.
• Line/phono: The signal from a turntable or a
line-level playback device coming from phono
input [4]. (Depending on the setting of the
rear-panel line/phono [5] switch.)
• CD: The signal from a CD or any other line-level
device connected to the CD input [3].
You can have signals coming in on all three in-
puts, and quickly change between them using
this heavy duty switch. Although the d.4 Pro
is a four channel mixer, this three-position
source selector for each channel allows you to select up
to 12 different sources without repatching!
31. HIGH EQ
This knob gives you up to 10 dB of boost at 4 kHz and
above, and turns off the signal at 4 kHz and above when
the knob is turned to the kill position. At the center
position U, there is no effect on the signal.
Note: When all three EQ knobs are turned to the kill
position, the signal is effectively muted and no signal
passes through to the output.
32. MID EQ
This knob gives you up to 10 dB of boost at 1 kHz, and
turns off the signal at 1 kHz when the knob is turned
to the kill position. At the center position, there is no
effect on the signal.
33. LOW EQ
This knob gives you up to 10 dB of boost at 300 Hz
and below, and turns off the signal at 300 Hz and below,
when the knob is turned to the kill position. At the cen-
ter position, there is no effect on the signal.

28. MIC ASSIGN
In the on position, the microphone signals are sent
to the main mix bus (equally left and right), without
affecting the level of your other program sources.
In the off position, the mic will not be heard.
In the spring-loaded, momentary talk position, each
program channel is reduced by 14 dB, so you can eas-
ily make your exciting mellow-toned announcements.
When released, the program channels return to their
original volume after a short delay..
The mic output to FireWire is not affected by the posi-
tion of this switch.
