Control Room Panel Expanded Features
★ Cut Left
○ Cuts (as in disables, mutes, turns off, etc.) the LEFT speaker output, with no change to the
input signal. Engaging this during normal, stereo monitoring will result in hearing the
RIGHT channel of the selected input source coming out of the RIGHT speaker only. During
MONO monitoring, results in hearing the MONO SUM of the selected input source in the
RIGHT speaker only.
★ Cut Right
○ Cuts (as in disables, mutes, turns off, etc.) the RIGHT speaker output, with no change to the
input signal. Engaging this during normal, stereo monitoring will result in hearing the LEFT
channel of the selected input source coming out of the LEFT speaker only. During MONO
monitoring, results in hearing the MONO SUM of the selected input source in the LEFT
speaker only.
★ Mono
○ Sums the selected input source to MONO in the CONTROL ROOM ONLY. Handy for judging
stereo image, phase correlation, and general awesomeness of your mix among other things.
As described above, sums BEFORE the speaker cuts to allow true MONO mixing on ONE
SPEAKER.
★ Left Pol
○ Flips the polarity (phase) of the LEFT CHANNEL of the selected input source. Handy for
checking phase coherence of a mix, stereo width, etc. When combined with MONO will play
only the difference (side) information from a stereo signal summed to the center channel.
★ CAL Mode
○ Disables the CONTROL ROOM VOLUME and replaces it with the CAL pot, accessible with a
tweaker on the front panel. Use this to pre-set a reference level, either with a sound level
meter or by feel, to ensure exacting level reproduction. Very useful when mixing for film &
television. CAL mode is still affected by the DIM control.
VU AUX DB9
★ This DB9 deals largely with the VU meter outputs, which are provided as a courtesy for those who
wish to purchase or build a glowing set of wonderful VU meters.
○ Two pins on the VU AUX DB9 carry signals to drive a pair of VU meters. They are derived
from the selected CONTROL ROOM SOURCE and are PRE FADER. Pin 4 carries the left signal
and pin 9 carries the right.
○ Ground is available on pins 1 and 5.
○ +15 volts is available on pin 2, - 15 volts on pin 6.
○ +12 volts for meter lamps is available on pin 3.
○ This DB9 contains the switching logic for the SOLO SYSTEM, described below. Connect pin 8
