Setting Up and Optimizing the Audio

For optimal audio quality, the audio input levels and the bass, treble, and loudness control must all be set up properly. Input and output (Preamp and Lineout) audio levels may need to be adjusted depending on the variation of output levels from different source devices. By default these switcher input levels are set for the consumer product line level of ‑10 dBV.

Bass, treble, and loudness should be adjusted once the input and output levels have been adjusted. By default the bass and treble have been set to 0, and loudness has been set to off.

Input level sensitivity can be adjusted via the front panel. Other adjustments must be performed via the supplied MediaLink Control Software (also available at www.extron.com) through the RS-232 port.

CTo avoid damage to your hearing and disturbing occupants of adjacent rooms, do not connect speakers to the MLS’s amplifier output until setup has been completed and volume has been set to the minimum level.
