Audio Levels
Figure 3-7 shows the audio level section in which there are 3 knobs:
Fig. 3-7: Audio Level Section
S The knobs are red because level changes affect on-air levels.
‘Program Out’ Knob
This knob controls either the program output level or voice-over level.
When no voice-over is active on the program bus, the knob controls the overall program output
level.
When one voice-over is active on the program bus, the knob controls the level of the selected
voice-over signal.
When both voice-overs are active on the program bus, the knob controls the level of both voice-
over signals. The effect is additive: a turn of the knob adds the same amount to each voice-over
level.
This knob adjusts the audio level in increments of 0.5 dB, from –100.0 dB to +28.0 dB.
‘Preset In’ Knob
When the panel is controlling an Imagestore 750, this knob controls the preset input level.
This knob adjusts the audio level in increments of 0.5 dB, from –100.0 dB to +28.0 dB.
‘Over Ratio/Duck Level’ Knob
When the panel is controlling an Imagestore 750, this knob controls the audio level of the
program source when a voice-over is mixed with program output. (That is called the “duck level.”
The term “over ratio” applies only to MCEs and MCPMs.)
When no voice-over is active on the program bus, the knob is inoperative.
When one voice-over is active on the program bus, the knob controls the audio level of the
program source for the selected voice-over signal.
