The IN31608 Presentation Switcher combines the easy operation and serial control capabilities of a projector switcher with the flexibility of a large matrix switcher. Featuring 16 x 8 matrix switching for RGBHV and stereo audio signals, 350 MHz bandwidth and two switching modes, the IN31608 is ideal for permanent installations, rentals, complex staging operations and any other audiovisual / display system requiring a high performance matrix switcher with intuitive operation. Four models are available to match the requirements for a variety of switching applications:

Model	Configuration	Signal Compatibility
IN31608	RGB	RGsB, Component Video, Y/C, Composite
IN31608A	RGB + Stereo Audio	RGsB, Component Video, Y/C, Composite, Balanced / Unbalanced Stereo Audio
IN31608HV	RGBHV	RGBHV, RGBS, RGsB, Component Video, Y/C, Composite
IN31608HVA	RGBHV + Stereo Audio	RGBHV, RGBS, RGsB, Component Video, Y/C, Composite, Balanced / Unbalanced Stereo Audio

Direct Switching Mode - In Direct Mode, the IN31608 acts as a projector switcher, routing composite, S-Video and RGB signals to the appropriate outputs. The installing technician determines which inputs should be routed to which outputs and configures the switcher appropriately. The user simply presses one of the 16 large input buttons and that input signal is automatically routed to the pre-programmed output or outputs. The IN31608 can also store and transmit commands to a data display device which tell the display to switch to the appropriate input and/or recall a convergence memory. Offering easy, one-touch operation for non-technical users, Direct Mode greatly simplifies system operations for a variety of audiovisual presentation system applications.

In Matrix Switching Mode - the IN31608 operates as a true 16 x 8 matrix switcher. Users press an output button followed by an input button and a new patch is immediately executed. The unit features large switching buttons and ample space for installers to affix custom labels specifying input sources and output devices. Matrix Mode is ideal for advanced operations requiring complete flexibility over input / output routing.

Featuring 16 Configuration Memories, the IN31608 can store and recall frequently used configurations for easy recall with a single button. The memories store all input / output patches as well as the current audio level for each output. The configuration memories make it easy to set up complex switching arrangements ahead of time and then recall them quickly and reliably at appropriate times during a show or presentation.

High Resolution Video Switching - With video bandwidth in excess of 350 MHz, the IN31608 provides ample performance for analog video signals at virtually any resolution and refresh rate.

The Blank Button temporarily disconnects the current input when it is activated. The blank button has two modes of operation. In the Default Mode, the Blank button disconnects all signal components (RGBHV) from the output. In the Sync Pass Mode, the Blank button disconnects only the RGB Signals from the output while the sync signal(s) continue uninterrupted. This lets the display device maintain sync lock while a black image is displayed. When the Blank button is pressed again, the RGB signal components are reconnected to the output and the display device instantly displays the input signal. Available only on IN31608HV / IN31608HVA models, Sync Pass mode is designed to operate with RGBS or RGBHV signals.

The RGB Delay feature may be engaged to provide a more attractive on-screen appearance when switching between various computer video sources. When switching between high resolution video soruces, data display devices normally require some period of time to identify and lock up to a new source. During this adjustment period, the screen may show flashing, resizing and other strange effects. With RGB Delay, each time a new input is selected the switcher immediately routes the sync signal(s) for the new input to the output, followed by the RGB signals at a later time. This allows the display device time to lock up to the new signal before any image is displayed (during the delay time the display shows black). When the RGB components are finally connected to the output, the display device has a solid lock on the new signal and immediately displys a stable image. The RGB delay time is adjustable from 0.5 seconds to 7.5 seconds in 0.5 second increments and can be set using serial commands or by pressing specific front panel buttons at power on.

Vertical Interval Switching capability provides glitch-free switches when used with synchronous video sources in the composite, s-video, component, RGsB, RGBS, and RGBHV formats. In vertical interval switching mode, the switcher delays the actual switch so that it occurs during the vertical blanking interval. The vertical interval switching mode can be engaged using an RS-232 serial command or by pressing specific buttons at power on. The IN31608 derives timing information from the house sync signal applied to the GENLOCK IN connector. A GENLOCK OUT connector is also provided to pass house sync to other genlockable devices in the video system.

Audio Breakaway Switching - The default operation mode for the IN31608 is audio-follow-video switching where audio and video signals are routed together. Users can separate the video and audio switching for special applications requiring this functionality. A single front panel button allows for quick selection of switching mode: Video + Audio, Video Only, or Audio Only.

Advanced Audio Switching Capability - The IN31608 offers very high quality switching and amplification for balanced or unbalanced stereo audio input and output signals. By wiring the inputs and outputs appropriately, unbalanced input signals can be output as balanced audio and vice versa. Unique gain trim levels can be adjusted and stored for each input, helping standardize signal levels among various types of audio sources. Each output has a master volume control and mute capability that can be controlled from the front panel or via RS-232 serial commands. Left / Right balance can also be adjusted as required using RS-232 commands.

Projector and Audiovisual Device Control - The IN31608 can store and transmit RS-232, RS-422 or RS-485 serial commands to control projectors, Inline products or other serially controlled A/V equipment. WindowsTM software provided with the switcher makes it easy to set up the unit and store control codes. The switcher in not pre-programmed with codes to control other devices. All serial control codes are provided by the installing technician.

Function Buttons - In addition to codes triggered automatically by input and output selection, the switcher can also store 8 additional code strings which are triggered by the four function buttons. The function buttons might be used to set the projector into standby mode, select lighting presets, switch scan doubler inputs, interface with a control system or to activate virtually any other serially controlled event.
