1 Chapter One Introduction About this Manual About the Matrix Switchers Definitions Features PRELIMINARY MVX 128 A VGA Matrix Switchers
Introduction About this Manual This manual contains installation, configuration, and operating information for the Extron MVX 128 A 12-input by 8-output wideband computer video (VGA) and audio matrix switcher. About the MVX 128 A Matrix Switcher The MVX matrix switcher distributes any of 12 inputs to any combination of 8 outputs. The matrix switcher can route multiple input/output configurations simultaneously.
The MVX 128 A inputs and outputs VGA video on 15-pin HD connectors and audio on 3.5 mm, 5-pole captive screw terminals. The audio switching can be either linked with the video (audio follow) or be independent of the video (audio breakaway). Adjustable input audio gain and attenuation compensates for level differences between audio inputs. The matrix switcher can be remotely controlled via its RS-232/RS-422 port.
Introduction, cont’d Features Video — The switcher inputs and outputs RGBHV or RGBS (VGA) video on 15-pin HD connectors. It can also switch RGsB, RsGsBs, component/HDTV, S-video, or composite video. Bandwidth — The MVX switcher provides a minimum of 300 MHz (-3 dB) video bandwidth, fully loaded. Audio inputs — The switcher inputs and outputs balanced or unbalanced stereo audio on 3.5 mm, 5-pole captive screw terminals.
Upgradeable firmware — The firmware that controls all switcher operation can be upgraded in the field via RS-232/RS-422, without taking the switcher out of service. Firmware upgrades are available for download on the Extron Web site, www.extron.com, and can be installed using the Windows-based control program. Labeling — The Extron label software ships with every Extron matrix switcher.

N This section is a detailed look at reading the output volume display on the matrix switcher’s front panel. If you do not need to read the exact value of the volume setting, skip this section. There are 65 steps of volume attenuation, with 1 dB per step (button push), except for 0-to-1, which is 35 dB. At maximum attenuation, no input LEDs are lit, 98 dB of attenuation is applied, and the audio output is effectively muted.
Operation, cont’d When all input LEDs are lit, the audio output is 100% of the audio input level. Another way to view the volume level is to think in terms of the attenuation that is applied to the output. Attenuation reduction is indicated by the lit or blinking input LEDs: when fewer input LEDs are lit, attenuation is greater (and the volume is less). • At minimum volume, all input LEDs are unlit and 98 dB of attenuation is applied to the output. The audio output is effectively muted.
Press and release the Output 1 button (figure 3-49). 3. The input LEDs display the selected output's audio volume level. In this example, the lit input buttons indicate 40 to 41.5 percent of the applied audio input. The unlit input buttons indicate an audio volume attenuation of 39 dB to 40 dB. Press and release the Output 1 button. The LED lights. –39 dB attenuation, 41.
Operation, cont’d Locking out the front panel (Executive mode) The front panel lock (Executive mode) limits the operation of the matrix switcher from the front panel. When the switcher is locked, all of the front panel functions are disabled except for the View-Only mode functions. See Viewing a configuration on page 3-15. Other than in View-Only mode, if the user pushes a front panel output button when the switcher is locked, the RGBHV and Audio LEDs flash twice and return to their previous state.
Selecting the RS-232/RS-422 protocol and baud rate The switcher can support either RS-232 or RS-422 serial communication protocol, and operate at 9600, 19200, 38400, and 115200 baud rates. The settings of these variables can be viewed and changed from the front panel. View and configure the switcher’s serial communications settings as follows: 1. To enter Serial Port Configuration mode, simultaneously press and hold all Control buttons (Enter, Preset, View, and Esc) (figure 3-54).
