1-5 CrossPoint Plus Matrix Switchers • Introduction
Operational flexibility — Operations such as input/output selection, setting of
presets, and adjustment of audio levels can be performed on the front panel
or over the RS-232/RS-422 link. The RS-232/RS-422 link allows remote
control via a PC or control system.
• QuickSwitch Front Panel Controller (QS-FPC™) — The CrossPoint Plus
series QS-FPC feature supports touch-of-a-button input and output selection,
preset creation and 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.
• Simple Instruction Set (SIS™) — The remote control protocol uses Extron’s
SIS for easy programming and operation.
Audio gain/attenuation — Users can set the input level of audio gain or
attenuation (-15dB to +9dB) via the RS-232/RS-422 link or from the front
panel. Individual input audio levels can be adjusted so there are no
noticeable volume differences between sources (figure 3).

Global presets — 16 memory presets are a time-saving feature that lets you set up
and store input/output configurations in advance and then recall those
configurations when needed with a few simple steps.
Switching flexibility — Individually buffered, independent matrix switched video
outputs with audio follow and audio breakaway for HVA versions.
• Any input to any or all outputs
• Quick multiple tie — Multiple inputs can be switched to multiple outputs
simultaneously. This allows all displays (outputs) to change from source to
source at the same time.
• Audio follow — Audio can be switched with the corresponding video input.
This feature allows any audio signal to be selected with any video signal
simultaneously to one or all outputs in any combination. Audio follow
switching can be done via front panel control or under RS-232/RS-422 remote
control.
