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.
