Resetting the switcher

The switcher can be reset to the factory defaults via the front panel or via RS-232

control.
To reset the switcher via the front panel, follow these steps.

1.

Unplug the switcher from the AC power source.

2.

Press and hold input selection buttons 1 and 4 while reapplying power to the

switcher (reconnecting it to the AC power source). All the input selection

LEDs blink for one second while the switcher is being reset.

These settings are reset (defaults are in parenthesis):

• Audio level (sensitivity = -10 dBV)
• Audio gain/attenuation (+6 dB for SA, MA, and non-amp models)
• Bass (0)
• Treble (0)
• Loudness (off)
• Line level audio output (stereo)
• Video type (configurable inputs = RGB)
• RGB delay (0 sec.)
• Monitor Output mode (RGB follow)
• Executive mode (off)
• Aux/Mix (on)
• Volume (41)

• switcher mode (single)

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.

To avoid damage to your hearing and disturbing occupants of adjacent

has been completed and volume has been set to the minimum level.
