Extron electronic MVX 44 series - Manual (Page 9)

1-3 MVX 44 / 48 / 84 / 88 VGA Matrix Switchers • Introduction
Features
Video — These switchers input and output VGA – UXGA RGBHV, RGBS, RGsB,
RsGsBs video, or component/HDTV signals on 15-pin HD female connectors.
Bandwidth — Bandwidth is 300 MHz (–3 dB). This high bandwidth allows the
switchers to switch high resolution video with no loss of signal quality.
Audio input — These switchers input unbalanced stereo audio signals on 3.5 mm
mini jacks.
Audio output — These switchers output balanced or unbalanced stereo audio
signals on 3.5 mm, 5-pole captive screw terminals.
Audio input gain/attenuation — You can set the input audio gain or attenuation
(–18 dB to +10 dB) via the RS-232 port or from the front panel. Individual
input audio levels can be adjusted so there are no noticeable volume
differences between sources and for the best headroom and signal-to-noise
ratio. This function also eliminates the need for separate preamps or
attenuators when used with professional (higher line level) and consumer
(lower line level) audio equipment.
Audio output level switch — The audio level of each output can be set to either
–10 dBV (consumer level) or +4 dBu (pro level) via RS-232 control only.
Audio follow — Audio can be switched with the corresponding video input.
Audio follow switching can be done via front panel control, optional IR 501
control, or the RS-232 port.
Audio breakaway — Audio can be broken away from its corresponding video
input signal. Audio breakaway switching can be done via front panel control,
optional IR 501 control, or the RS-232 port.
Switching flexibility — Provides individually buffered, independent matrix
switched outputs with audio follow and audio breakaway for audio versions.
• 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.
Operational flexibility — Operations such as input/output selection and setting of
presets can be performed on the front panel, via the RS-232 port, or using the
optional IR 501 small matrix universal remote control. The RS-232 port
allows remote control via a PC or control system.
• Front panel controller — The MVX series front panel controller feature
supports touch-of-a-button input and output selection, preset creation and
selection, and audio gain and attenuation control.
• RS-232 control — The switcher’s RS-232 port allows remote control via a PC
or control system using Extron’s Simple Instruction Set ™ (SIS ™ ) or the
included Windows ® -based control program.
• Optional IR remote control — The MVX switchers are remote controllable,
using the optional IR 501 Small Matrix IR Remote Control.
Upgradeable firmware — The firmware that controls the switcher’s operation can
be upgraded in the field via the RS-232 port, without taking the switcher out
of service, opening the switcher enclosure, and replacing the firmware chip.
Firmware upgrades are available for download on the Extron Web site,
www.extron.com
, and they can be installed using the Windows-based control
program.
