Extron electronic ISM 482 manual Integration Scaling Matrix Switcher Introduction

Audio gain/attenuation — Users can set the input level of audio gain or attenuation (-24 dB to +9 dB) via the RS-232 port, Ethernet link, or from the front panel. Individual input audio levels can be adjusted so there is no noticeable volume difference between sources.

Ethernet port — Supports connection to an Ethernet LAN so that the switcher can be accessed and operated from anywhere in the world with a computer using a standard Internet browser.

Quad-standard video decoder — The switcher uses a digital, four-line adaptive comb filter that can decode NTSC 3.58, NTSC 4.43, PAL, and SECAM.

Test patterns — The switcher features built-in test patterns to aid in monitor or projector setup and evaluation.

Blue mode — The switcher can be set to output the blue video signal and sync signal(s) only, to help installers calibrate the monitor or projector.

Triple-Action Switching™ (RGB delay) — RGB delay mutes the R, G, and B video planes to blank the screen while the scaler locks to the new sync, so that a noise-filled scramble is not shown on the monitor during the transition. The time delay between the RGB and sync signals is user adjustable up to five seconds under front panel, Simple Instruction Set (SIS™), and Windows program control.

Auto memories — The eight inputs support 16 auto-recall memories each, based on the incoming frequency. Information on sizing, centering, detail, contrast, and brightness is saved.

Auto Image™ — The auto imaging feature automatically sizes and centers the selected input to fill the screen. Auto imaging can be selected for individual inputs as desired or set to automatically size and center each new input selection.

Memory presets — The ISM 482 has memory for up to 128 presets that allow the user to use RS-232 commands to save and recall color, tint, contrast, brightness, centering, sizing, and filtering information.

Aspect ratio memories — Three memories for each input save different color, tint, contrast, brightness, detail, size, and centering settings.

Freeze mode (under SIS and Windows program control only) — Locks the output display to the selected image. Once frozen, an input can be removed without losing the output image. This feature lets the ISM store a still image.

Rack mounting — The 3U high switcher can be mounted in any conventional 19" wide rack.
