The
Source
section provides for the selection of inputs (4 x stereo/4 x 8-channel) and
returns (8 x stereo/8 x 8-channel). The selected input can be monitored at the input
or output stage of the console.
The Input section itself offers a router for assigning various channel confi gurations
to match the SMPTE channel confi guration (which is used throughout the console).
Each input channel is equipped with an On, Phase Reverse and a special Trim switch
for precise increments in 0.5 dB steps from -9,5 dB to +6 dB.
The
Insert
section is unique. It offers control functions for an automated patchbay,
called the “Insert Box“. Up to eight, 8-channel processors can be connected to this
breakout box. The mastering engineer can store and compare up to four sequences
with the push of a button. A global bypass switch (Insert On) activates or deactivates
the Insert Box.
The Master section is outfi tted with an eight-channel Master fader control for
dynamic mastering purposes. The Master fader and Monitor Level controls are
specially built potentiometers with a tolerance of less the 0.5 dB over their entire
range in all 8 levels. This system dispenses with step ladders and proves a quantum
leap in dynamic mastering control.
The
Output
section offers the same precision trim controls as the Input section.
In each channel, level differences, which may have been introduced by outboard
processing, may be compensated for in 0.5 dB steps from -9.5 dB to +6 dB.
The Monitor section features a central volume control and buttons for Mute and Dim
levels. Two stereo loudspeaker sets and two surround loudspeaker sets of up to
eight speakers can be connected to the MMC 1.
There is an On and Solo button for each loudspeaker. The Solo function operates
as Solo-in-Place, while a Solo-to-Center switch shunts other channels through the
center speaker for better comparison. There is provision to monitor the LFE on the
L/C/R. Three Mono functions (L/R, LS/RS, L
t/o
/R
t/0
) and two mode buttons for stereo
or multi-channel operation round out the Speaker Management section.
The Meter Bridge houses an RTW Surround Monitor 10800x and eight large VU
meters with superb ballistics to display meterings with ultimate precision. The RTW
Surround Monitor remote control is built into the console next to the calibration
switches for the VUs. VUs may be calibrated to eight different values (0 dB/-2/-4/-6/-
8/-10/-12/-14 dB).
Note:
Metering always follows monitoring; depending on the selected monitoring
signal (input, output or returns), the according metering is displayed automatically.
