Extron Electronics MAV Plus Series User Guide - Manual (Page 14)

Definitions
The following terms, which apply to Extron matrix switchers, are used throughout this guide:
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.
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 anywhere
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 — 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.
