System 7SC • Introduction1-4
Features and Options
Features
350 MHz (-3 dB) video bandwidth
Configurable video inputs —
• Inputs 1 to 6 — Six sets of 5 BNC connectors on the rear panel accept
RGBHV/RGBS/RGsB computer video, component video, S-video or
composite video input, and are individually configurable.
• Input 7 — Input 7 (on the front panel) includes a VGA-type 15-pin HD
connector for RGB computer video input, a 4-pin mini DIN connector for
S-video input, and one RCA connector for composite video input. Input 7
can be configured for one of these video formats, or it can be set to
automatically detect the active input.
This input is buffered and can drive a signal approximately 50 feet (15
meters) using Extron cable.
Switcher slaving — Input 1 can be used to connect and control a slaved switcher,
expanding the capacity of the System 7SC to a maximum of 16 inputs.
Buffered video outputs — Five rear-panel BNC connectors and one VGA-type
15-pin HD port provide connections for RGB output. Both outputs (the BNCs
and the 15-pin HD port) are active at all times.
Seven balanced or unbalanced stereo audio inputs — The front panel mini stereo
jack or RCA connectors (for unbalanced input only), and six rear panel
captive screw connectors accept audio inputs. Each input’s gain and
attenuation levels can be individually set.
Two balanced or unbalanced stereo audio outputs — One fixed line level output
(for a recording device) and one variable line level output (for use with an
amplifier or mixer) are provided on 3.5 mm, 5-pole captive screw terminals.
The variable line level output can be controlled via the front panel, the IR 701,
optional control pads, or an RS-232 system.
Audio breakaway — Audio and video can be switched separately via RS-232.
Four ways to control the switcher — The switcher’s front panel, a computer or
other RS-232 control device, an IR 701 remote control, or a remote keypad can
all be used to control the switcher.
RS-232 configuration — The System 7SC can be configured by using the Extron
control software for Windows, or by using a third party control system.
Room controls — Two relays are provided for controlling lights, window
coverings, a display screen or another item in the room. The Room control
buttons can be set to also send an IR or RS-232 command.
Projector control — The System 7SC can control the projector’s display power,
video mute and mode functions.
Projector control command learning — The switcher can “learn” new projector
control commands by storing IR signals it receives through the front panel,
via files downloaded from Extron’s command library, or from commands
entered via the Windows-based control program. Learned commands can be
associated with any of the front panel input selection or control buttons, and
they are output through the IR Emitter/IR Broadcaster or the projector
control RS-232 port.
Inactivity projector shutdown timer — Using the included control/configuration
software, the switcher can be set to monitor the time elapsed since the last
input selection (or other function) and to send a command to turn the
projector off after a set period of inactivity.
