This pushbutton switch selects the sensitivity of the left and right
Program VU meters; +4dbm operation in the normal (up) position, and -
18dbm operation when depressed. The operation of this switch in no
way modifies the electronic operation of the mixer.
If the switch is set to its normal (up) position, then a 0VU reading on the
meter indicates that a signal value of +4dbm is being yielded at the
program output. If the switch is depressed, then the meters become
22db more sensitive, thereby making it necessary, given the same input
levels, to turn down the Stereo Program Master Control to once again
achieve a 0VU meter reading. However, this same 0VU reading now
yields a signal value of -18dbm at the program outputs as a result of the
lower Program Master Control setting. This setting should prove
sufficiently low enough for the Microphone or Synth inputs of a
recording console.
As with the Program Meter Sensitivity Switch, this switch selects only
the sensitivity of the Solo/Effects VU meter and in no way modifies the
electronic operation of the mixer. The same two different operating
levels are available; +4dbm or -18dbm.
The 6 pin DIN connector provides a convenient interface to any passive
stereo volume pedal via an optional interface cable. This connector
provides a stereo send and stereo return insert for the stereo mix signal.
The left/right send to this connector is the sum of all input channels and
effects returns. The left/right returns are "Pre" the program, monitor and
headphone controls. This allows a "what you hear, is what you get"
adjustment when the expression pedal is operated.
This connector is only active when the Expression Pedal Switch is
enabled. The operation of the pedal does not affect the levels from the
cue, click, aux returns, and solo signal. For the pin assignment
configuration for the 6 pin DIN connector and installation instructions,
refer to the Interface Section of this manual.
This unbalanced 1/4" T.S. phone type jack provides a dedicated feed to
an external tuning device. The source for the output is either the sum of
all signals feeding the program master or any signal(s) that are soloed.
If, for example, you need to tune only one synth module while others are
active as well, simply depress its associated solo or PFL switch and it
will be isolated to the tuner output. 5. Left/Right Meter Sensitivity
