Optimizing the Audio

Each individual input audio level can be adjusted within a range of -24 dB to +9 dB, so there are no noticeable volume differences between sources and for the best headroom and signal-to-noise ratio. Adjust the audio gain and attenuation as follows:

1.	Connect audio sources to all desired inputs and connect the audio outputs to
	output devices such as audio players. See “Input connections” and “Standard
	output connections”, in chapter 2, “Installation”. For best results, wire all of
	the inputs and the outputs unbalanced.
2.	Power on the audio sources, the switcher, and the audio players.
3.	Switch among the inputs (see “Selecting an input and switching it to the
	program output”, earlier in this chapter), listening to the audio with a critical
	ear or measuring the output audio level with test equipment, such as a VU
	meter.
4.	As necessary, adjust the audio level of each input (see “Video & Audio
	Configuration menu”, earlier in this chapter) so that the output level is
	approximately the same for all selected inputs.

Troubleshooting

The following tips may help you in troubleshooting.

•Some symptoms may resemble others, so you may want to look through all of the examples before attempting to solve the problem.

•Be prepared to backtrack in case the action taken does not solve the problem.

•It may help to keep notes and sketches in case the troubleshooting process gets lengthy. This will also give you something to discuss if you call for technical support.

•Try simplifying the system by eliminating components that may have introduced the problem or made it more complicated.

•For sync-related problems: Portable digital projectors are designed to operate close to the video source. Sync problems may result from using long cables or from improper termination. A sync adapter, such as Extron’s ASTA (active sync termination adapter), may help solve these problems.

•For LCD and DLP projectors and plasma displays: In addition to the sync- related information above, check the user’s manual that came with the projector for troubleshooting tips, as well as for settings and adjustments. Each manufacturer may have its own terms, so look for terms like “auto setup”, “auto sync”, “pixel phase”, and “tracking”.

General checks

1.	Ensure that all devices are plugged in and powered on. The switcher is
	receiving power if the LCD is displaying the default display cycle.
2.	Ensure that an active input is selected on the switcher.
3.	Ensure that the proper signal format is supplied.
4.	Check the cabling and make corrections as necessary.
5.	Call the Extron S3 Sales & Technical Support Hotline if necessary.

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.
