Features

Inputs — This switcher offers 4 RGBHV, RGBS, RGsB, RsGsBs, HDTV, component video, S-video, or composite video inputs on BNC connectors.

Outputs — 2 RGBHV, RGBS, RGsB, RsGsBs, HDTV, component video, S-video, or composite video outputs are available on BNC connectors.

Stereo audio output can be balanced or unbalanced, on 3.5 mm, 5-pole captive screw terminals.

Bandwidth — Bandwidth is a minimum of 300 MHz (-3dB), fully loaded. This high bandwidth allows Extron’s switchers to switch everything from NTSC video to high-resolution computer displays.

Operational flexibility — Operations such as input/output selection and adjustment of audio levels can be performed on the front panel or over the RS-232 link. The RS-232 link allows remote control via a control system.

•QuickSwitch Front Panel Controller (QS-FPC™) — The CrossPoint 42 HVA QS-FPC feature supports touch-of-a-button input and output selection, and audio gain and attenuation control.

•Windows-based control program — Extron’s Windows-based control program provides a versatile range of operational options with its graphical interface and drag-and-drop/point-and-click operation. The Windows-based control program also has an emulation mode that lets you create a switcher configuration file at the home office and then download it for use by the switcher on site.

•Extron’s Simple Instruction Set™ (SIS™) — The remote control protocol uses Extron’s SIS for easy programming and operation.

Audio gain/attenuation — Users can set the level of audio gain or attenuation (-18dB to +24dB) via the RS-232 link or from the front panel. Individual input audio levels can be adjusted so there are no noticeable volume differences when switching between sources (figure 1-2).
