Dissolve Speed submenu

The Dissolve Speed submenu displays and allows you to set the duration of the dissolve effect when switching the preview output to the program output.

Use either the Adjust knob or the Adjust knob to select the dissolve speed from 0.1 seconds to 5.0 seconds in 0.1 second steps. The default is 1.0 seconds.

Test Pattern submenu

The Test Pattern submenu lets you select from among several test patterns and assigns the selected pattern to an output. The test patterns are helpful when you are adjusting the connected displays for color, convergence, focus, resolution, contrast, grayscale, and aspect ratio.

Use the Adjust knob to select a test pattern. The options are: Color Bars, crosshatch, 4 x 4 crosshatch, grayscale, crop, alternating pixels, film aspect ratios 1.78, 1.85, 2.35, and ramp.

Use the Adjust knob to assign the output(s) for the selected test pattern. Select among neither output (both off), the preview output, the program output, or both outputs.

Blue-Only Mode and Edge Smoothing submenu

The Blue-Only Mode and Edge Smoothing submenu lets you turn the blue mode and edge smoothing features on and off. Blue-only mode is helpful in the setup of the color and tint of the incoming video signal. In the blue-only mode, only the sync and blue video signals are passed to the display. Edge enhancement mode smooths edges of a picture by minimizing the differences between pixels.

Use the Adjust knob to turn blue-only mode On or Off. The default is Off.

Use the Adjust knob to turn edge enhancement mode On and Off. The default is Off.

Preview and Program Blanking submenus

The Preview Blanking submenu and Program Blanking submenu allow you to adjust the top and bottom line blanking on the preview and program monitors within a range of 0 to 200 lines. During scaling, captioning and tapehead switching in the video’s blanking area may show up as picture noise. Using blanking, you can add black lines at the top and bottom edges of the image to eliminate edge noise.

Use the Adjust knob to increase or decrease the top line blanking. The default is 0 lines.

Use the Adjust knob to increase or decrease the bottom line blanking. The default is 0 lines.

RGB Delay submenu

The RGB Delay submenu displays and lets you set the RGB delay when switching a selected input to the preview output. With RGB delay, sync is never removed from the preview display. Rather, the ISS blanks the RGB (video) outputs while the scaler locks to the new sync, and then switches the RGB signals. This allows a brief delay for the displays to adjust to the new sync timing before displaying the new picture, which appears without glitches. RGB delay is also known as Triple-Action Switching™ or video mute switching.

Use either the Adjust knob or the Adjust knob to select the blanking period (RGB delay time) from 0 seconds to 5 seconds in 0.1 second steps. The default is 0.2 seconds.

ISS 408 specifications

Extron Electronics is renowned for its contributions to the audiovisual industry, providing high-performance devices that meet the demands of professional environments. Two prominent products in their lineup are the ISS 108 and ISS 408 image scaling switchers, which are designed to enhance the management and quality of video signals in various applications.

The Extron ISS 108 is an 8x1 image scaling switcher that allows users to seamlessly switch between multiple video sources while ensuring high image quality. One of its main features is the ability to support a variety of video formats, including resolutions up to 4K. This versatility is crucial for applications in education, corporate settings, and events where different video sources may be required.

In terms of technology, the ISS 108 is equipped with advanced image scaling capabilities that improve the visual quality of the content being displayed. The device utilizes Extron's patented Vector 4K scaling technology, which enhances the clarity and detail of the images while maintaining the integrity of the source material. This technology is invaluable in environments where every detail matters, and it ensures that presentations are delivered at their best quality.

The ISS 408, on the other hand, takes the capabilities of the ISS 108 and elevates them further by offering 4x1 switching capabilities. This enables users to connect up to four video sources, giving them more flexibility in content management. The ISS 408 also supports 4K video resolutions, further solidifying Extron's commitment to delivering high-quality solutions.

Both models are designed with user-friendly interfaces, allowing for easy operation and integration into existing AV systems. They offer extensive control options, including RS-232 and Ethernet, enabling users to incorporate them into automation systems and control environments efficiently.

Another important characteristic of the ISS series is their built-in security features, such as password protection and lockout modes, which are essential for maintaining the integrity of sensitive content being delivered in corporate or educational settings.

In summary, the Extron ISS 108 and ISS 408 provide powerful solutions for image scaling and video switching. With advanced technologies like Vector 4K scaling, robust connectivity options, and intuitive control interfaces, these devices stand out as essential tools for any professional audiovisual application. Their focus on quality, flexibility, and security makes them ideal choices for enhancing video presentations in various environments.
