1-3 CrossPoint 42 HVA Matrix Switcher • Introduction
Features
Inputs — This switcher offers 4 RGBHV, RGBS, RGsB, RsGsBs, HDTV, component
video, S-video, or composite video inputs on BNC connectors.
Stereo audio input can be balanced or unbalanced, on 3.5 mm, 5-pole captive
screw terminals.
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).
