Front Panel Features

Power/data/audio LED — Indicates power is applied. This LED also has two secondary functions:

Serial communication function — The Power/data/audio LED blinks off and on to indicate that an IR signal has been received.

Audio level function — In Audio Setup mode, the Power/data/audio LED lights when the selected input audio signal is > the reference level and is unlit when the signal is below the reference level. Adjust the gain until the LED blinks frequently. If the LED is almost always on, but occasionally blinks off, the level is too high. If the LED is almost always off, but occasionally blinks on occasionally, the level is too low.

I/O button selects video and audio, video, or audio for input selection.

Video and Audio LEDs indicate whether video and audio, video, or audio is selected. The Audio LED blinks to indicate audio is broken away.

Input buttons select an input to tie to an output.

Definitions

Tie — An input-to-output connection

Set of ties — An input tied to two or more outputs

Configuration — One or more ties or sets of ties

Current configuration — The currently active configuration (also called configuration 0)

Audio Setup button and LED enable you to view and/or change the current audio level setting for each input. Audio Setup is a secondary function of the I/O button.

Down (<) and Up (>) buttons and LEDs decrease or increase the audio level for the selected input and indicate the decrease and increase. On 8-output switchers, < and > are secondary functions of the Output 7 and Output 8 buttons.

+dB/–dB LEDs indicate the polarity of the audio level setting (+dB = gain, –dB = attenuation). +dB and –dB are secondary functions of the Video and Audio LEDs.
