Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

By default, the audio output follows the video switch. Audio breakaway, which is commanded via the front panel (see chapter 3) or under RS-232/422 control, via the SIS or Windows-based control program, allows you to select from any one of the audio input sources. See chapter 3, Operation, chapter 4, Programmer’s Guide, and chapter 5, Matrix Software for details.

D connector for serial RS-232/RS-422 control.

If desired, attach an MCP 1000 remote control panel master unit to the switcher’s RS-232/ RS-422 connector. You can also attach an MKP 1000 remote keypad or MCP 1000 slave unit to the MCP 1000 master unit. Refer to the

MCP 1000 Remote Control Panel User’s Manual and the MKP 1000 User’s

Manual for details.

See chapter 4, Programmer’s Guide, for definitions of the SIS commands and chapter 5, Matrix Software for details on how to install and use the control software.

The MAV switchers are factory configured for RS-232 control. To use the switcher under RS-422 control, an internal cable must be moved. See appendix B for the procedure for shifting the cable.

External sync connection

When the switcher switches between inputs, the resulting change in image should be seamless, or clean. Video models of the MAV 1616/168 Series switcher can use an external signal to synchronize switching during the vertical interval. Without the external sync locking feature, switching between inputs can result in a brief rolling (sync loss) or a brief change in the picture size.

7External Sync In connector — Connect an external sync signal to this BNC connection for genlocking the video signal in broadcast or other sync-critical applications.

External Sync Out connector — Connect any downstream equipment that requires genlocking to this BNC connector to route the external sync signal throughout the system in broadcast or other sync-critical applications.

Figure 2-9 shows a basic external sync configuration. The Ext Sync In connector receives a timing signal. The Out connector allows the signal to be passed on to another video device, if required.

MAV specifications

Extron electronics are renowned for their cutting-edge technology in the realm of AV systems and distribution solutions. Among its notable products, the MAV series stands out as an advanced tool for managing audio/video signals across various applications. The Extron MAV, or Multi-Format Audio/Video Switcher, provides a seamless approach to switching between multiple sources effortlessly, making it an integral component in modern AV setups.

One of the main features of the Extron MAV is its multi-format switching capability. It supports a wide variety of video signals, including HDMI, VGA, display port, and composite video, allowing users to connect different devices without worrying about compatibility issues. This versatility is particularly beneficial in environments such as classrooms, conference rooms, and auditoriums, where multiple input sources like laptops, projectors, and other multimedia devices are commonly used.

Another significant characteristic of the MAV series is its robust audio integration. The MAV not only switches video signals but also routes audio through its built-in audio switcher. This feature simplifies the workflow by allowing users to manage audio from the same interface, ensuring synchronized audio and video output. The device also supports advanced audio features, including audio de-embedding and analog audio outputs, making it suitable for complex AV systems.

The MAV employs Extron's proprietary technologies to enhance signal integrity. For instance, it adopts advanced signal processing to prevent degradation of video quality, maintaining a clear and crisp image even over long distances.
