Limiters
The ProMix 6 audio mixer is equipped with switchable output limiters.
The
control switch for these limiters is located on the right hand side of the front panel
between the tape return monitor switch and the power switch. The output limiter
switch is labeled "LIM" and is a three-way switch. The three choices are labeled
"Off" , "S" , and "G" In the "off" position the limiters are turned off and no output
signal limiting occurs.
In the "S" (separate) position, the two limiters act
independently of each other. This position is used most often when you have an
interviewer panned to one output and the interviewee panned to the other output.
This type of recoding is called split tracks and you should use the limiters in their
"S" mode for this type of work. In the "G" (ganged) position, the limiters are
ganged together and will track one another. If a high level signal on either limiter
input causes one of the limiters to activate, both limiters will activate. This type of
limiting is normally used when recording stereo signals. By keeping the limiters
ganged together, the overall stereo image will not appear to shift when limiting
occurs. It is highly recommended that you use the output limiters at all times.
This will serve to protect your recording from unexpected audio peaks that would
otherwise overload your recorder and ruin the sound quality of your recordings.
In most ENG situations, split tracks are used and thus the "S" setting on the
limiter switch is employed.
Headphone Selection
On the right side of the front panel there is a rotary switch that is used to control
what you monitor on your headphone outputs. This switch has four positions that
are marked as follows: "S", "L", "R", and "M" These settings are abbreviations
for Stereo, Left, Right, and Mono. In the "Stereo" setting, the headphones are
fed a normal stereo signal. The left headphone is fed a signal from the left output
and the right headphone is fed a signal from the right output. When the switch is
set to "Left", both drivers of your headphones are fed a signal from the left output.
When this switch is set to "Right" both drivers of your headphones are fed a
signal from the right output. When set to "Mono" both headphone drivers are fed
a signal that is a mono sum of both the left and right outputs.
Headphone Volume
Located directly above the headphone selection switch is a headphone volume
control pot. This pot raises or lowers the volume of the audio signal going to your
headphones. Turning the pot counterclockwise will lower the volume. Turning
the pot clockwise will raise the volume of the headphones. Turning the pot fully
counterclockwise will turn off the headphone volume completely. Please note the
headphone volume safety warnings at the beginning of this manual. Operating
this mixer with too high of a headphone volume setting may cause permanent
hearing damage. You are fully responsible for your own hearing protection
when using this mixer as we do not have control over your operating
