I/O and Audio Setup button —

•Press and release — Pressing the I/O button cycles through video and audio, video only, or audio only for input and output selection. See the Video and Audio LEDs ( 8 ) for the sequence.

•Press and hold — The I/O button also serves as the Audio Setup selection button. To enable the Audio Setup mode, press and hold the Audio Setup button for about 2 seconds until the Audio Setup LED ( 9 ) lights . In Audio Setup mode, you can view and/or change the current audio level setting for each input. See “Adjusting input audio gain and attenuation” on page 3-19.

Audio Setup mode times out after approximately 30 seconds of inactivity.

Alternate reset function — This button is also used to perform a system reset. See “Resetting the system to factory defaults (audio/video switchers)” on page 3-26.

Video/+dB LED and Audio/–dB LED —

•I/O selection — The Video and Audio LEDs indicate whether video and audio, video only, or audio only will be selected using the input buttons ( 3 ) and output buttons ( 4 ).

Pressing the I/O button advances through a cycle of video and/or audio selections as shown on figure 3-3.

•Audio Setup mode — The –dB and +dB LEDs indicate the polarity of the audio level setting. See “Adjusting input audio gain and attenuation” on page 3-19. Both LEDs light to indicate unity gain (0 dB).

9Audio Setup LED — The Audio Setup LED lights red to indicate that the switcher is in Audio Setup mode. See “Adjusting input audio gain and attenuation” on page 3-19.

Alternate IR error function — The Audio Setup LED also indicates errors when you use an IR 501 small matrix remote control. The LED lights for approximately 1 second when the switcher receives an unexpected or out-of-sequence IR command from the remote control. The switcher otherwise ignores the command.
