Operation, cont’d

13Auto Switch Active LED — When lit, the Auto Switch Active LED indicates that the switcher is in autoswitch mode. When unlit, the switch is in normal (manual) mode. See Switch mode in this chapter.

This LED will never light on audio-only switchers.

Executive mode controls and indicator

Audio switchers have audio gain and attenuation adjustments. In executive mode, front panel adjustment of the audio level is locked. The level cannot be adjusted from the front panel until the panel is unlocked. See Executive mode in this chapter.

Audio gain and attenuation adjustments are still available via the RS-232 link when the switcher is in executive mode.

10Mode button — The Mode button is used with the Executive mode button to toggle executive mode on and off. See Executive mode (front panel security lockout) in this chapter.

This button is a secondary function of the Input 1 button.

14Executive Mode button (unlabeled) — The Executive mode button is an unlabeled secondary function of the Input 4 button. Executive mode is used with the Mode button to toggle executive mode on and off. See Executive mode (front panel security lockout) in this chapter.

15Executive Mode LED — The Executive Mode LED indicates that the switcher is in executive mode, and that the front panel I/O button and all audio gain and attenuation adjustments are locked.

Front Panel Operations

The following paragraphs detail the power up process and provide sample procedures for switching inputs, viewing and adjusting the audio level, changing between normal and autoswitch mode, and toggling executive mode on and off.

Power

Plug in the switcher. On all switcher models, power is automatically applied when the power cord is connected to an AC source. When AC power is applied, the switcher performs a self-test that blinks the front panel LEDs during the test. An error-free power up self-test sequence leaves the Auto Switch Active, Executive Mode, Video, Audio, and Input LEDs on or off in the same configuration as they were when power was last removed.

If an error occurs during the self-test, the switcher locks up and will not operate. If your switcher locks up on power-up, call the Extron S3 Sales & Technical Support Hotline.

Plug in all system components and turn on the input devices (such as DVD players, laserdisc players, VCRs, and DSS receivers) and the output devices. Set the input devices to output video using each device’s own operating instructions. Select an input. The image should appear on the screen. If no image appears, see Troubleshooting — If No Image Appears, in this chapter.

Switching inputs

An input can be selected for output using the front panel buttons. In switchers with both video and audio, the audio input can switch with the video input (audio follow) or either can be switched separately (audio breakaway). Select an input as follows:
