HyperTerminal, a third party controller, or the MediaLink
Control/Configuration Software). The gain and attenuation for
the Aux/Mix input are adjustable only via the switcher’s front
panel. (See page 3-3 for Aux/Mix details.)
Setup via the MediaLink

Control Software
To avoid damage to your hearing, the output
volume should be set as low as possible before you
test the sound system.
1. Cable and power on all the equipment.
2. Start the MediaLink Control Software (see page 4-7), and
select the Switcher (MLS) Config portion of the program
(the second tab from the left).
3. Select an audio input. See the picture below for an
example.
4. Use the following table to determine the gain or
attenuation. Match the desired level for balanced output
or for unbalanced output, depending on how the output
connector is wired.

Unbalanced
If you wire an audio output for balanced output, the
MLS will output a unity signal (input level = output
level). If you wire an audio output for unbalanced
output, it causes the audio signal to be attenuated by
6 dB (gain = -6 dB).
For dBV the reference is 1 volt.
For dBu the reference is 0.775 volts.
5. In the control program, move the Audio Input Level slider
to select the gain/attenuation for that input,
as shown at left.
6. Repeat steps 3–5 for the other three inputs.
7. Test the system by listening to audio output for each input.
Start by setting the audio output set to the lowest level.
7a. If the audio output is too loud or is clipping
(becoming distorted as the loudest parts are cut off),
decrease the gain for that input.
7b. If the output is too soft or inaudible, increase the gain.
