4.Stop speaking into the microphone. The main program audio should recover to the previous level after approximately two seconds. If not, increase the threshold by turning the Talk Over Threshold Adjust pot counterclockwise.

+24V Phantom Power switch

If a condenser microphone is used and power is required, set the +24V Phantom Power switch on the back panel of the switcher to On.

Decoder Loop Function

For data projectors, plasma displays, and other displays on which the composite video and S-video inputs do not work independently, the SWP123 is equipped with a decoder loop function that converts all composite video signals to S-video. This is accomplished by using an external Extron YCS Transcoder or a VYC 100N/P composite video to S-video decoder. Once the decoder loop is configured and programmed, the following occurs when you select a composite video input:

•The switcher automatically selects Input 4 in the S-video A/V group to enable the loop.

•The Extron YCS Transcoder or VYC 100N/P composite video to S-video decoder converts all composite video signals coming through the switcher to S-video.

Wiring the decoder loop

1.Connect the output of the Composite Video A/V group to the composite input of the transcoder or decoder.

2.Connect the S-video output of the transcoder or decoder to S-video input 4 of the SWP switcher.

3.Connect the S-video output of the SWP switcher to the S-video input of the display device.

4.Activate the decoder loop using the correct RS-232 serial command (see chapter 5) or the ICS100 Control Software (see chapter 4).
