MAV Plus 2412 A	24x12 Stereo Audio	60-474-03	Retired

This product has been retired.

The Extron MAV Plus 2412 A is designed to route balanced or unbalanced stereo audio signals. It features backlit I/O selection buttons, audio input gain and attenuation, audio output volume adjustment, and Ethernet control technology.

Ethernet Control

The MAV Plus Series is equipped with an integrated, high performance Web server that provides technical support personnel with the ability to receive service and failure messages through an e-mail-enabled cell phone, PDA, pager, or e-mail account. Utilizing Ethernet control, the help desk can also view embedded Web pages to manage, monitor, and troubleshoot the switcher for the following:

AV Resource Management

Remotely select input and output ties for audio only, video only, or audio and video
Name and select global I/O presets
Set audio input and output volume levels
Upload firmware updates via the Internet

Operating Status and Diagnostics

Monitor primary and redundant power supply voltages
Monitor internal product operating temperature
Recall firmware revision and other data for improved Help Desk support
Obtain immediate notification via e-mail for power supply failure, overheating, and other critical service information

Features

Inputs: Captive screw connectors

Outputs: Captive screw connectors

Video genlock — Audio switching can be synchronized with video switching for clean, accurate audio-follow-video transitions.

Enhanced QS-FPC™ - QuickSwitch Front Panel Controller — Provides a discrete, backlit button for each input and output, allowing for simple, intuitive operation.

View I/O mode — Allows users to easily see which individual inputs and outputs are actively connected. Available from the front panel, RS-232, or via Ethernet control.

Global presets — Frequently used I/O configurations may be saved and recalled either from the QuickSwitch Front Panel Controller or RS-232 serial control. This time-saving feature allows you to set up I/O configurations and store them in memory for future use.

I/O grouping — Allows the matrix switcher to be virtually divided into smaller sub-switchers, making installation and control easier. I/O grouping allows specific outputs, like those designated for a specific video format, to be grouped together.

Rooming — All models can be programmed to group selected outputs into specific "rooms," each with its own set of unique presets. Each room can support up to 16 outputs. A total of 10 rooms, with 10 presets per room, are available.

Switches both balanced and unbalanced stereo audio — Accepts both signals on captive screw connectors.

Audio input gain and attenuation — Allows users to set the level of gain or attenuation for each audio input channel, eliminating noticeable volume differences when switching between sources.

Audio output volume adjustment and muting — Each individual output has volume control adjustment via the front panel, RS-232 or Ethernet control. Audio output levels can be set dynamically at different levels to feed the audio amplifier, thus eliminating the need for a preamplifier in many system designs.

Tri-color, backlit buttons accept custom window labels — The backlit buttons on the front panel of the MAV Plus matrix switchers can be custom-labeled for easy identification. Buttons illuminate red, green, or amber, depending on function, for ease-of-use in low-light environments.

Ethernet monitoring and control — Engineered to meet the needs of professional AV environments, Ethernet control enables the MAV Plus Series to be proactively monitored and managed over a LAN, WAN, or the Internet, using standard TCP/IP protocols. Ethernet control provides for remote selection of input and output ties, adjustment and control of audio input and output levels, and advanced system diagnostics.

RS-232 and RS-422 control port — Using serial commands, the MAV Plus Series can be controlled and configured via the included Windows-based control software, or integrated into a control system. Extron products use the SIS™ - Simple Instruction Set command protocol, a set of basic ASCII code commands that allow for quick and easy programming. The RS-232 and RS-422 port also makes it easy to install firmware updates.

Control software — Provides a graphical, drag-and-drop interface for I/O configuration and other customization functions via RS-232 and RS-422 remote control. Also offers an emulation mode for configuration of an off-site matrix switcher. The I/O configuration may be saved for future downloading to the matrix switcher.

Optional control panels and keypads — Provide the flexibility to control a MAV Plus Series matrix switcher from a remote location.

Front panel security lockout — If a MAV Plus matrix switcher is installed in an unsecured environment where easy access is not desirable, a security lockout feature may be implemented. During lockout mode, a special button combination is required to operate the front panel.

Rack-mountable metal enclosure — 5U, full rack width

Highly reliable, energy-efficient internal universal power supply — The 100-240 VAC, 50/60 Hz, international power supply provides worldwide power compatibility with high demonstrated reliability.

Redundant power supplies — Primary and back-up power supplies are internally mounted. The power supply system is configured to automatically switch over to a hot spare power supply if the primary power supply fails. This means no loss of functionality in the event of a primary power supply malfunction.
