Installation, cont’d

Gain and attenuation are adjustable (from -18dB to +24dB) for each input (1 through 4) via RS-232 control only (using HyperTerminal, a third party controller, or the MediaLink Control 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.

output, it causes the audio signal to be attenuated by 6dB (gain = -6dB).

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.

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.
