3-11System 7SC • Operation and Configuration
Edge Smoothing
This feature smooths edges of objects in a picture by minimizing the differences
between pixels. The default setting is “Yes”.
Add Slave (slaving switchers)
To expand the capacity of the System 7SC to a total of up to 16 inputs, connect and
configure a slave switcher. A maximum of one Extron switcher can be used.
A slave cable, Extron part number 26-386-01, is required for the RS-232 connection,
and the slave’s video output must be connected to input 1 of the System 7SC.
See “Connecting and Slaving a Switcher” in chapter 2 for cabling instructions, and
see the following diagram.

These Extron switchers can be slaved to
the System 7SC:
• System 8 PLUS • SW4 AR MX HV
• System 10 PLUS • SW 6 AR MX HV
The System 7SC with a slaved switcher
After the slave switcher has been connected to the System 7 and both switchers are
powered on, select the input quantity (10, 8, 6, or 4 inputs) that corresponds to the
attached slave switcher from the Add Slave submenu of the Switcher Setup/
Configuration menu.
Autoselect #7 (front panel input automatic signal type selection)
The front panel input (input 7) accepts video and one audio input. Only one video
format and one audio port will be active at a time on the front panel.
The active input type (RGB, S-video, or composite video) can be specified via the
LCD menu, or, in autoselect mode, the System 7SC automatically detects the active
video signal and selects that signal type whenever input 7 is active/selected. The
lowest voltage level that can be detected by the switcher is 2.0 Vp-p.
