Listen Bus Or Foldback; Preset/Reset Switch - Crown PIP-LITE Reference Manual

Networked PIP Series
• The Cycle Preset Mode will advance the PIP through a defined range of presets on a
low-to-high transition of the AUX input. The inversion object changes the activity to a high-
to-low transition. The range of presets is defined by the max preset and min preset
controls. Once the max preset is reached the next defined AUX input event will cycle the PIP
to the minimum preset.
• AUX Input Inversion: This control allows the low state to activate the selected func-
tion. Normally, the high state activates the selected AUX input function.
The AUX port provides a power supply for the AUX input. This 15 VDC at 15 mA supply can
be connected through a switch to the AUX input. This allows a simple switch closure to
operate the aux input without the need of an external power supply. See Section 6.1 for
details on using the AUX port.

5.1.10 Listen Bus or Foldback

The AUX port is also used for the Listen Bus connection. Two pins of the connector pro-
vide a balanced line-level audio output that can be selectively driven by either channel
under IQ software control. Multiple PIP-Lite and PIP-USP3 modules can have their Listen
Bus outputs wired onto a single bus allowing the system operator to listen to any of their
outputs.

5.1.11 Preset/Reset Switch

The Preset/Reset switch is a recessed pushbutton located between the Data and Preset indi-
cators. It is activated by a straightened paper clip or similar object. This switch can be used
to change presets, restore settings to factory default or restore all the presets to the factory
defaults. During operations of the switch, the Data indicator flashes as an aid to the user.
To select a preset: Remove all audio input signals. With the PIP powered up, momen-
tarily hold the preset switch in for one flash of the Data indicator (less than 2 seconds) and
then release. The PIP will load the next preset in the defined preset range. The range of pre-
sets is defined by the Maximum Preset and Minimum Preset controls. Once the Maximum
Preset is reached the next momentary depression of the switch will cycle the PIP to the
Minimum Preset. The Preset indicator will flash the number of the selected preset followed
by a pause. Restore the audio input signals.
To restore the unit to factory default settings: Remove all audio input signals. Hold
the Reset/Preset switch in for two flashes of the Data light (longer than 2 seconds). The
Data indicator will flash rapidly for a moment. Restore the audio input signals.
To restore the unit including presets to factory default settings: Remove all
audio input signals. Hold the Reset/Preset switch while applying power to the unit. The
Data and Preset indicator will both light. Release the switch within 5 seconds (before the
Data and Preset indicators go out). The Data indicator will flash rapidly for a moment.
Restore the audio input signals.
