Definitions

The following terms, which apply to Extron matrix switchers, are used throughout this manual:

Tie — An input-to-output connection.

Set of ties — An input tied to two or more outputs. (An output can never be tied to more than one input.)

Configuration — One or more ties or one or more sets of ties.

Current configuration — The configuration that is currently active in the switcher (also called configuration 0).

Global memory preset — A configuration that has been stored. Up to 64 global memory presets can be stored in memory. Preset locations are assigned to the input buttons and (where necessary) output buttons. All presets can be selected from the front panel for either saving or retrieving. When a preset is retrieved from memory, it becomes the current configuration. All presets are also accessible under RS-232/RS-422 or Ethernet control.

Room — A subset of outputs that are logically related to each other, as determined by the operator. The switchers support up to 10 rooms, each of which can consist of from 1 to 16 outputs.

Room memory preset — A configuration consisting of outputs in a single room that has been stored. When a room preset is retrieved from memory, it becomes the current configuration. The switchers support up to 10 presets per room.

Features

Video (video BMEs) — All switchers input and output video on BNC connectors.

CrossPoint 450 Plus Wideband Video — These switcher BMEs input and output wideband RGBHV or RGBS video. They can also switch RGsB, RsGsBs, component/HDTV, S-video, or composite video.

MAV Plus Low Resolution Video — These switcher BMEs input and output NTSC 3.58, NTSC 4.43, PAL, or SECAM video or HDTV video inputs. Depending on the video format of the switcher system, these switchers can distribute low resolution RGsB, RsGsGs, component/HDTV, S-video, or composite video.

Bandwidth —

CrossPoint 450 Plus Wideband Video — The wideband switcher BMEs provide a minimum of 450 MHz (-3 dB) video bandwidth, fully loaded.

MAV Plus Low Resolution Video — The low resolution switcher BMEs provide a minimum of 150 MHz (-3 dB) video bandwidth, fully loaded.

Audio inputs (audio BMEs only) —

Stereo audio BME — Input and output balanced or unbalanced stereo audio on 3.5 mm, 5-pole captive screw terminals.

Mono audio BME — Input and output mono audio on 3.5 mm, 3-pole captive screw terminals.

Audio input gain/attenuation (audio BMEs only) — Individual input audio levels can be adjusted so there are no noticeable volume differences between sources. Users can set the input level of audio gain or attenuation (-18 dB to +24 dB) via the Ethernet link, RS-232/RS-422 link, or the front panel.
