Switcher Operations

The following paragraphs detail the power up process and provide sample procedures for selecting an input and viewing and adjusting the audio level.

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 LED for the previously selected input lit and all other Input LEDs off.

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 computers and scalers) 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

A new input can be selected using the front panel buttons. Select a new input as follows:

1.

Select the desired input by pressing the associated input button.

2.

Observe that the LED for the selected input lights.

 

 

The switcher must be in normal (manual) mode.

 

 

An input can also be selected using an RS-232 device or a third party contact closure device. See chapter 4, Remote Control. Separate video and audio inputs (audio breakaway) can be established under RS-232 control. If audio is broken away, the selected video input is indicated by a steadily lit input LED, and the selected audio input is indicated by a blinking input LED.

Switching inputs on the front panel can only switch video and audio together (audio follow). Even if audio was previously broken away, audio follows the video on front panel input selection.

Audio gain and attenuation (SW2 RGBHV A, SW4 RGBHV A, and SW6 RGBHV A only)

Audio switchers have audio gain and attenuation adjustments. The audio level of each input can be adjusted through a range of –18 dB to +24 dB to ensure that there is no noticeable volume difference among sources and to eliminate the need for separate preamps or attenuators when used with professional (higher line level) and consumer (lower line level) audio equipment.

The audio level can be adjusted from the front panel or by using Extron’s

Windows-based control program.

The switcher must be in normal (manual) mode.

1.

Press and release an input button to select an input.
