Audio — Input and output balanced or unbalanced stereo audio on 3.5 mm, 5-pole captive
screw terminals.
Audio input gain/attenuation — Individual input audio levels can be adjusted so there
are no noticeable volume differences between sources. Users can set the input level of audio
gain or attenuation (-18 dB to +24 dB) via the Ethernet link, RS-232 link, or the front panel.
Audio output volume — The audio volume of each output can be displayed and adjusted
through a range from full output to completely silent from the front panel or via RS-232 or
Ethernet control.
Switching flexibility — Provides individually buffered, independent matrix switched
outputs with audio follow and audio breakaway.
NOTE: Audio switching is independent of the video groups.
Tie any input to any or all outputs within a video group
Quick multiple tie — Multiple inputs can be switched to multiple outputs within a
video group simultaneously. This allows all displays (outputs) to change from source
to source at the same time.
Audio follow — Audio can be switched with its corresponding video input via
front panel control or under Ethernet or RS-232 remote control.
Audio breakaway — Audio can be broken away from its corresponding video
signal. This feature allows any audio signal to be selected with any video signal
simultaneously to one or all outputs in any combination. Audio breakaway switching
can be done via front panel control or under Ethernet or RS-232 remote control.
Operational flexibility — Operations such as input/output selection, setting of presets,
and adjustment of audio levels can be performed on the front panel or via the Ethernet or
RS-232 link. The Ethernet and RS-232 links allow remote control via a PC or control system.
The Ethernet link allows multiple remote links with two levels of password protection.
Front panel control — The front panel controller supports input and output
selection, preset creation and selection, and audio gain and attenuation and volume
control. The front panel features slots for labels that can identify each input and
output with text or graphics.
Windows-based control program — For RS-232 remote control from a PC, the
Extron Windows-based control software provides a 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 the Extron SIS
for easy programming and operation.
Remote control panels and keypads — The switcher is remote controllable, using
the optional MKP 2000 and MKP 3000 remote control panels. The remote control
devices are easy to use and provide tactile buttons for quick selection. Each MKP
can be used for input-to-output switching or one-touch switching for a particular
output and selecting global presets.
Upgradable firmware — The firmware that controls all switcher operation can be
upgraded in the eld via RS-232 or Ethernet, without taking the switcher out of service.
Firmware upgrades are available for download on the Extron website, www.extron.com,
and they can be installed using the Windows-based control program.
Labeling — The included Extron Button-Label Generator software lets you create labels to
place in the front panel I/O buttons, with names, alphanumeric characters, or color bitmaps
for easy and intuitive input and output selection. Alternatively, labels can be made with any
Brother
®
P-Touch
®
or comparable labeler.
