The Extron ISM 824 MultiSwitcher is a unique modular matrix switcher that allows for simultaneous video and RGB scaling plus wideband switching in a single, compact enclosure. It combines the powerful signal routing capabilities of an eight input, eight output, wideband matrix switcher with the versatility of four customizable outputs. The ISM 824 can be equipped with any of the eight available output boards for initial project requirements, and then upgraded at any time in the future with additional boards as system needs evolve and expand. It is ideal for applications such as boardrooms, auditoriums, and classrooms that require high-performance signal routing with flexible, on-board signal processing.

As a matrix switcher, the ISM 824 is similar in performance and features to Extron's popular CrossPoint 450 Plus Series. The ISM 824 offers eight inputs that are fully configurable from RGBHV and HDTV to composite video, and two universal, pass-through wideband outputs. The ISM 824 provides exceptional performance in the most demanding, very high resolution computer-video and audio routing systems with features such as ADSP™ - Advanced Digital Sync Processing, DSVP™ - Digital Sync Validation Processing, audio output volume control, and Ethernet control and monitoring.

Expandable and Upgradeable

With its unique, powerful expansion capability, the ISM 824 can be equipped initially with any of the output boards for a specific project, and then upgraded in the future with additional boards as system needs evolve and expand. Updates to the ISM 824 can easily be accomplished in the field without the need for factory servicing or changes to the internal hardware.

Output Expansion Board Options

Eight output expansion boards are available for the ISM 824, with the same advanced video processing technologies employed in Extron scalers, signal processors, scan converters, and twisted pair matrix switchers. The Universal RGB & Video Scaler Output Board features high performance RGB and video scaling, with upconversion and downconversion of high resolution RGB signals, as well as standard definition video signals. The Universal RGB & Video Scaler Board is available in three versions:

Analog - outputs RGBHV or component video with selectable rates up to WUXGA (1920x1200) resolution, as well as HDTV 1080p/60.
DVI - outputs selectable rates up to 1920x1200 and HDTV 1080p/60.
HD-SDI - outputs standard serial digital rates, including 720p 50/60, 1080i 50/60, and 1080p/24.

The Video Scaler Output Board is ideal for applications requiring video-only scaling with RGB pass-through. It scales standard definition composite video and S-video signals to a common, high resolution output rate. It offers selectable output rates from 640x480 to 1400x1050, including HDTV 1080p/60.

The Scan Converter Output Board delivers an optimized, scan-converted video output for compatibility with low resolution video monitors as well as VCRs, DVD recorders, or videoconferencing.

The MTP Twisted Pair Universal Transmitter Board transmits video, audio, and control signals up to 600 feet (185 meters) on a single CAT 5/5e/6 or Skew-free UTP cable. Also, as a universal transmitter, it supports all input signal types in mixed-signal routing applications.

Finally, Single and Dual Output Wideband Boards are available for additional matrix switcher outputs.

Integrated Matrix Switching and Signal Processing

The ISM 824 provides optimum integration flexibility while reducing system complexity and cost. With both matrix switching and signal processing capabilities in one 3U enclosure, system configuration and set-up can be accomplished from a single location, saving installation cost and time. At the same time, control system design and programming is simplified. Additionally, the ISM 824 is ideal for locations where equipment rack space is at a premium.

Versatile Control Possibilities from a Single Location

All features and functions of the ISM 824, including those of any installed output boards, are fully accessible from the front panel, as well as through the RS-232 and Ethernet ports. The ISM 824 thus offers versatile control functionality for managing all source distribution and signal processing within an AV system.

Eight available output board options:
- Universal RGB and Video scalers - DVI, HD-SDI,
or Analog RGB output
- Video scaler
- Scan converter
- MTP Twisted Pair
- Single output wideband
- Dual output wideband

User-friendly interface — An intuitive menu-driven LCD interface, direct access buttons, and precise rotary controls enable detailed adjustment of image settings.

Wideband 8x8 matrix switching — Provides exceptional performance in the most demanding, very high resolution computer-video and audio routing systems.

Eight fully-configurable inputs — Accept RGBHV, HDTV, component video, S-video, and composite video signals.

ADSP™ - Advanced Digital Sync Processing — An exclusive, all-digital process that regenerates the sync signal waveform and restores sync level to 5.0 V p-p, TTL, specifications. This ensures a stable sync signal for improved signal compatibility with any LCD, DLP, plasma, or other digital display device.

DSVP™ - Digital Sync Validation Processing — Verifies active sources by polling all inputs for valid sync signals. DSVP then transmits the horizontal and vertical sync information to the user through the Ethernet or serial ports.

Triple-Action Switching™ for RGB delay — Blanks the screen when switching to a new source. The new sync signals precede the RGB signals, so there is no glitch shown during the transition. The time delay between the RGB and sync signals is adjustable up to five seconds through front panel, Ethernet, or serial control.

Audio breakaway — Provides the capability to break an audio signal away from its corresponding video signal, allowing the audio and video signals from one source to be switched to different destinations.

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 — Can be set dynamically for each channel through the front panel or serial control, eliminating the need for an audio preamplifier in many system designs.

16 global presets — Frequently used I/O configurations may be saved and recalled either from the front panel controller, Ethernet, or serial control. This time-saving feature allows I/O configurations to be set up and stored in memory for future use.

QS-FPC™ - QuickSwitch Front Panel Controller with tri-color backlit buttons — Provides a discrete button for each input and output, allowing for simple, intuitive operation. Buttons can be custom labeled for easy identification. The buttons illuminate red, green, or amber, depending on function, for ease of use in low-light environments.

Front panel security lockout — Prevents unauthorized use in non-secure environments. In lockout mode, a special button combination is required to operate the switcher from the front panel controller.

Ethernet monitoring and control — Engineered to meet the needs of professional AV environments, Ethernet control enables the ISM 824 to be proactively monitored and controlled 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 RS-232 serial commands, the ISM 824 can be controlled and configured via the Extron Windows®-based control program, 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.

Front panel configuration port — A front panel serial port allows easy accessibility for configuring the ISM 824 without having to access the rear panel.

Windows® 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.

Rack-mountable 3U, full rack width metal enclosure

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.
