Extron electronic ISM 824 manual Output connections, Balanced Stereo Output

Output connections

The basic device has video and audio connectors for two pass-through outputs.

With four optional cards installed, there are video and audio connectors for up to eight outputs.

NThe number of outputs is dependent on the number and types of cards installed.

G	Pass-through video output BNC connectors — Connect RGB video displays
	to these two sets of female BNC connectors for unprocessed pass-through
	signals (RGBHV, RGBS, RGsB, RsGsBs, HDTV, component video, S-video, or
	composite video). See figure 2-8 for the relevant connector positions used in
	each video format.

H	Audio output connectors — Connect audio devices, such as an audio
	amplifier or powered speakers to these two 3.5 mm, 5-pole captive screw

connectors. The connectors output the selected unamplified, line level audio. See figure 2-9 to properly wire an output connector.

CAUTION

For unbalanced audio, connect the sleeve(s) to the center contact ground. DO NOT connect the sleeve(s) to the negative (-)

CConnect the sleeve to ground (Gnd). Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

By default, the audio output follows the video switch. Audio breakaway, commanded via the front panel, the Ethernet link, or the RS-232/RS-422 link, allows selection from any one of the audio input sources.

See chapter 3, “Operation and Setup”, chapter 4, “SIS™ Programming and Control”, chapter 5, “ISM 824 Multiswitcher Software”, and chapter 6, “HTML Operation”, for details.
