RAC 104 • Remote Control
Front Panel Security Lockout (Executive
Modes)
To prevent accidental changes to the controller settings, the
front panel controls can be locked using one of two executive
modes. The user turns the executive modes on and off using
either the SIS or the Windows-based control program via the
RS-232 connector. While an executive mode is on, the locked
controls can be adjusted through the RS-232 device only.
Executive mode 1 locks the tone controls and channel selector
buttons only. The user can continue to change the volume
via the front panel.
Executive mode 2 locks all the front panel controls.
Presets
The user can program up to three presets for each channel using
the SIS or the Windows-based control program via the RS-232
connector. The presets allow the user to save the current input
gain and output volume, bass, and treble settings for recall at a
later time.
When two channels are tied together, selecting a preset for
either channel will set the volume, bass, treble, and gain for
both channels. Input gain for tied channels can be adjusted
independently.
Mute
The user can mute each channel using the SIS or the
Windows-based control program via the RS-232 connector.
• Volume and tone settings can still be adjusted while a
channel is muted.
• When two channels are tied together, selecting mute or
unmute for one channel will mute or unmute both.
• When the user ties a muted channel to a channel that is not
muted, the RAC 104 unmutes the muted channel
automatically.
