Operation/Switch Functions
SP 1 to SP 3
These switches can toggle up to three loudspeaker pairs on and off (and may
serve as individual mute switches).
Mono
The Mono function creates a mono sum from the stereo signal left and right
channels and provides for a mono-compatibility check of the stereo mix. This
switch functions globally on all three monitor outs, and both speakers of a
pair receive the mono signal.
Dim
The Dim switch reduces (by about -20 dB) the monitor volume of all outputs
for loudspeakers and headphones and is a very practical addition to control
the overall mix—or to enable a suddenly needed and intelligible telephone
conversation. When the Talk function is activated, the Dim is automatically
enabled (refer to “Talk” below).
HP On
This HP On switch toggles the headphone output in and out. Its presence
means that a connected headphone does not have to be unplugged should
the engineer only need them quiet for a moment.
Talk
The Talk button activates the Talkback function. As long as this button
is pressed, one can speak with the musician over the integrated MTC front
microphone. To avoid feedback, pressing this button automatically reduces
monitor volume by -20 dB.
The installed electret microphone has an omnidirectional pattern that allows
for good pickup even when a speaker finds himself several meters from the
MTC.
The Talk function may also be activated over an external key/button or switch
which is connected to the rear panel footswitch input (refer to Rear Panel/
Inputs/Footswitch on page 7).
Tip: When employed, an external key/button behaves just as if it were the
installed talk button, e. g., you may speak until releasing the key/button. On
the other hand, using an external switch means that your Talk function will
remain active until you again trip the switch.
