Extron electronic MVX 88 Series ユーザーズマニュアル

 These switchers input and output VGA – UXGA RGBHV, RGBS, RGsB, 

RsGsBs video, or component/HDTV signals on 15-pin HD female connectors.

 Bandwidth is 300 MHz (–3 dB).  This high bandwidth allows the 

switchers to switch high resolution video with no loss of signal quality.

 These switchers input unbalanced stereo audio signals on 3.5 mm 

mini jacks.

 These switchers output balanced or unbalanced stereo audio 

signals on 3.5 mm, 5-pole captive screw terminals.

 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 allows 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.

 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 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 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.

 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.

 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.

 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, 

, and they can be installed using the Windows-based control 

program.
