8 LCD screen — This screen displays basic system status, menu, and
configuration information. You will use it primarily during switcher
configuration. During regular operation, the LCD displays the volume level.
9 Volume/Adjust knob and Min/Mid/Max LEDs — Rotate this knob to adjust
the volume when the switcher is in regular user mode, and use it to select
options from menus in switcher setup mode. The LEDs indicate different
things depending on the mode (user or setup) the switcher is in. See
appendix A for an audio block diagram.
• In the user (regular) mode the LEDs function as volume level indicators.
Rotate the Volume knob to adjust the output level of the Preamp and
Amplified outputs. The volume range is 0 to 40 steps, which is
displayed as 0% to 100% in the configuration software.

Normal: a blinking LED indicates that the level is
set properly for maximum power output.
NOTE If the Max/Clip LED lights, the audio may be clipped.
During setup audio/video breakaway is disabled.
Per-input audio level settings can be adjusted via this front panel knob or via
RS-232/Telnet/Web browser control.
There is an input gain adjustment tolerance of ±2 dB.
Optimizing the Audio
Input and output audio levels may need to be adjusted depending on the variation
of output levels from different source devices. The Preamp default output level is
set for the consumer product level of -10 dBV. The level of the Lineout output
cannot be adjusted: input level = output level.
Bass and treble should be adjusted once the input and output levels have been
adjusted. By default, bass and treble have been set to 0.
Input levels can be adjusted via the front panel (for the FPC model) or the free
Global Configurator software. Other adjustments must be performed via the
software (available at www.extron.com) through one of the switcher’s
Configuration/RS-232 ports or the Ethernet (LAN) port.
CAUTION Do not connect speakers to the switcher’s amplifier output until setup has
been completed and volume has been set to the minimum level.
