LEVEL
is the master monitor level control that determines the overall signal level sent to the
monitor output (except when DIM or CUT controls are engaged). This control also appears in the
control window
3.5.3.4
Monitor Modes
There are three monitor modes, the monitor mode depends on the setting of the Stereo Loudspeaker
Output Enable and Stereo/Surround switches.
Stereo Loudspeaker Output Enable
This switch is labeled “STEREO L/S ENA.” It only has an effect when stereo monitoring is selected.
It determines whether the stereo monitor bus is routed to the left and right stereo monitor outputs
(stereo output on) or to the front left and front right surround monitor outputs (stereo output off).
Surround/Stereo Monitoring
This switch can be toggled to select stereo or surround monitoring. When stereo monitoring is
selected the monitor output routing depends on the stereo output enable as described above. When
surround monitoring is selected, the monitor surround bus is always routed to the six surround
monitor outputs and all other monitor outputs are muted.
Some mixer controls maintain separate settings for surround and stereo monitoring. This switch
affects the behavior of the following controls:
•
Program inserts
•
Program EQ
•
Program Dynamics
•
Annex filter
•
Master fader
•
Faders in the channel section (see §
3.6.9

3.5.3.5
Solo and Cut
The solo buttons cause the corresponding monitor outputs to be soloed when they are engaged, the
cut buttons mute the corresponding output. There are six buttons because only six monitor channels
can be active at a time. In Stereo Mode, only the L and R buttons affect the monitor output.
3.5.3.6
Fold-down buttons
Although there are two fold-down buttons only one of them can be on at a time. They control three
fold-down options: stereo fold-down, mono fold-down, and no fold-down (both buttons out).
The oscillator produces a non-band-limited triangular waveform of selectable level and frequency. It
is available on the inputs to all the input channels in the same form. The OSC switch turns it on and
off. It is calibrated such that at 1 kHz, nominal 0 dB is at a signal level of 0 dB SACD.

Note,
nominal level at other frequencies may vary, because the higher harmonics of the triangular wave
will be more or less filtered than those where the fundamental is at 1 kHz.
The LFE Filter controls determine the slope and frequency of a low-pass filter which affects only the
surround LFE program output.
