Extron electronic 50 manual Introduction, cont’d, 2 - Audio gain and attenuation

Introduction, cont’d

control program also has an emulation mode that lets you create a switcher configuration file at the home office and then download it for use by the switcher on site.

•Simple Instruction Set (SIS™) — The remote control protocol uses Extron’s SIS for easy programming and operation.

Audio gain/attenuation — Users can set the input level of audio gain or attenuation (-15dB to +9dB) via the RS-232/RS-422 link or from the front panel. Individual input audio levels can be adjusted so there are no noticeable volume differences between sources (figure 1-2).

Global memory presets — 12 global memory presets are a time-saving feature that lets you set up and store input/output configurations in advance and then recall those configurations when needed with a few simple steps.

Switching flexibility — Individually buffered, independent matrix switched video outputs with audio follow and audio breakaway for models with audio.

•Any input to any or all outputs

•Quick multiple tie — Multiple inputs can be switched to multiple outputs simultaneously. This allows all displays (outputs) to change from source to source at the same time.

•Audio follow — Audio can be switched with the corresponding video input. This feature allows any audio signal to be selected with any video signal simultaneously to one or all outputs in any combination. Audio follow switching can be done via front panel control or under RS-232/RS-422 remote control.

•Audio breakaway — Audio can be broken away from its corresponding video signal. Audio breakaway switching can be done via front panel control or under RS-232/RS-422 control.

Remote control — The Matrix 50 switchers are remote controllable, using the MKP 1000 master control keypad and any combination of MCP 1000 slave control panels and/or MKP 1000 slave control keypads. The remote control devices are easy to use and provide tactile buttons for quick selection. Each MCP 1000 can be used for one-touch switching for a particular output and selecting global presets. Each MKP 1000 dedicated to an output can be used to select a different input for that output or to select a preset.
