50. Control Room / Phones Control
This control is used to adjust the audio level of
the Control Room and Phones feeds, for use in
the monitoring and tracking of audio. The signal
is then sent to the Control Room outputs on the
rear of the Impact mixer, as well as the Phones
jack on the face of the mixer.
Typically, the signal sent to the Control Room and Phones
mixing buses will be the Main L and R signal, however if
any AFL (After-fader listen) buttons are pushed, they will
take precedent over the Main L and R signal. If, however,
a PFL (Pre-fader listen) is pushed, that will be the signal
heard instead of either the AFL or Main L and R signals
(as shown in the table below).

51. Level Meter
These 12 segment level meters give an accurate indica-
tion the level of the Main left and right audio signals. The
0 dB indicator illuminates is approximately equal to an
output level of +4 dBu (balanced), and the PEAK indica-
tor illuminates about 1.5 dB before the signal is dynami-
cally clipped. To make the maximum use of audio, set the
various level controls so that it sits steadily around 0 dB
to make full use of audio, while still maintaining fantastic
clarity.
If any PFL or AFL buttons are activated, the Main L/R Lev-
el Meter will display the properties of the Control Room /
Phones signal instead.
52. PFL/AFL Indicator
The PFL/AFL indicator on the top of this meter is bi-col-
ored, and illuminates green when a PFL switch is active
and red for an AFL. Due to the fact that any PFL has prior-
ity over any AFL (see section 49), if both an AFL and PFL
are activated, only the green PFL indicator will illuminated
and processed by the CTRL RM/PHONES control area.

53. Power Indicator
The Power Indicator will light up when the power of the
mixer is on; in case you weren't too sure.
54. Main L/R Faders
These fader are the final level control for the Main Left
and Right audio feeds, sent to the Main Left and Right
outputs on the rear of the device. When pushed all the
way up, the Main L/R fader provides 10 dB of gain to the
signal, and when set all the way down, the signal is ef-
fectively muted.
