or press and hold the button while you apply power to the switcher.
Performing an absolute system reset from the rear panel
This function is identical to the front panel system reset (see “Performing a system
reset from the front panel” on page 3-41) without requiring you to power down
the switcher. This function is also identical to the
Esc
ZXXX SIS command
(see chapter 4, “Programmer’s Guide”). A system reset:
• Clears all ties and presets
• Clears all audio or RS-232 mutes
• Clears all output pre-peaking
• Sets all audio/RS-232 wire pairs to audio
•
Sets all input audio levels to unity gain (+0 dB)
• Sets all output volume levels to 100% (0 dB of attenuation)

these settings, use the Windows-based Matrix Switchers Control Program and

(See chapter 5, “Matrix Software”).
