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 32 global memory presets can be stored in memory. Preset locations are assigned

to the input buttons and (where necessary) output buttons. Up to 20 or

32 (depending on the number of input and output buttons) 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 models have 32 presets; on models with fewer than 32 input and output buttons, preset numbers that are too high to be available from the front panel are still accessible under serial port or Ethernet control.

Features

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

CrossPoint — Both switcher models input and output ultra-wideband RGBHV or RGBS video. They can also switch RGsB, RsGsBs, component/HDTV, S-video, or composite video.

MAV Plus — These switchers 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, these switchers can distribute low resolution RGsB, RsGsGs, component/HDTV, S-video, or composite video.

Bandwidth —

CrossPoint — Both CrossPoint switcher models provide a minimum of 425 MHz (-3 dB) video bandwidth, fully loaded.

MAV Plus — The MAV Plus switchers provide a minimum of 150 MHz (-3 dB) video bandwidth, fully loaded.

Audio inputs (audio models) —

All audio models, with the exception of the MAV Plus 128 AV RCA — Input and output stereo audio, balanced or unbalanced, on 3.5 mm, 5-pole captive screw terminals.

MAV Plus 128 AV RCA — Input and output unbalanced stereo audio on left and right RCA connectors.

Audio input gain/attenuation (audio models) — 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, either serial port link, or the front panel.

Audio output volume (audio models) — The audio volume of each output can be displayed and adjusted through a range of full output to completely silent from the front panel or under serial port or Ethernet control.
