Operation, cont’d

Auto Imaging and Auto Memories submenu

The Auto Imaging and Auto Memories menu provides a means to turn the auto imaging and auto presets features on or off for all input selections.

If auto imaging is set to on, the ISS automatically sizes and centers the selected input to fill the screen when a new frequency is input. If auto imaging is set to off, the ISS sizes and centers the selected input only when it is commanded using the input button. See “Auto imaging an input”, earlier in this chapter. Rotate the Adjust knob to toggle auto imaging on or off for all input selections.

The auto memories feature saves and recalls centering, sizing, and filtering information, based on the input frequency. Auto memory settings may conflict with user preset settings. When you use a control system to switch inputs and then recall a user memory, the delay in recalling the auto memory settings could result in the recalled auto memory settings overwriting the recalled user memory settings. To prevent this conflict, turn auto memories off. Rotate the Adjust knob to toggle auto memories on or off.

Enhanced Mode submenu

The Enhanced Mode submenu provides a means to turn enhanced mode on or off. Enhanced mode is an automatic gain control for S-video or composite video input signals scaled and applied to the program output. If the input signal level is too weak, the signal gain is increased; if the input signal level is strong, the signal gain is decreased.

Use either the Adjust or the Adjust knob to select among enhanced mode off or on for the program output. The default is Off.

Enhanced mode is effective only for S-video and composite video input signals.

Pixel Phase submenu

The Pixel Phase submenu displays and lets you set the pixel phase, which is the timing of the digital scaler’s sampling. Sampling at the optimum pixel phase results in a brighter scaled output.

Use either the Adjust or the Adjust knob to select the pixel phase for both outputs simultaneously from 0 to 31. The default is 16.

Preview Switch Mode submenu

The Preview Switch Mode submenu lets you set the way the preview output responds to the cut or dissolve operation.

•Stay mode — When you initiate either a cut or dissolve operation, the video and audio signals on the preview output are applied to the program output (figure 3-14) and also continue to be applied to the preview output until another input is selected.

The video input switches between the switcher’s two internal scalers, resulting in a switching report being issued on the RS-232 port (see “Switcher-Initiated Messages” in chapter 4, “Operation”).

•Swap mode — When you initiate either a cut or dissolve operation, the preview and program outputs are swapped (figure 3-14). The video and audio signals on the preview output are applied to the program output. The video and audio signals that had been applied to the program output are applied to the preview output.

Each of the switcher’s two internal scalers retains the same video inputs; only the outputs are swapped. No switching report is issued on the RS-232 port (see “Switcher-Initiated Messages” in chapter 4, “Operation”).

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.
