Reference Manual
IQ-PIP-USP3/CN
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
offset the aux input without the need of an external power supply. See Section 6.1 for details
on using the AUX port.
4.1.8 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 IQ-PIP-USP3/CN powered
up, momentarily hold the preset switch in for one flash of the Data indicator (less than 2
seconds) and then release. The IQ-PIP-USP3/CN will load the next preset in the defined
preset range. The range of presets 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.
4.2 Amplifier Control and Monitoring
4.2.1 User Presets
The control settings for all the functions can be stored as presets. A total of ten presets can
be saved in the IQ-PIP-USP3/CN’s nonvolatile memory. Each preset can be named with a
30 character name describing its function, which is also stored in the PIP’s memory.
• The Store Preset Control saves the current setting to the specified preset.
• The Recall Preset Control recalls the specified preset settings.
• The Preset Valid Monitor indicates if a change has been made to any setting since the
last time a preset has be saved or recalled.
• The Last Stored or Recalled Preset Monitor indicates what the Last Stored or
Recalled preset is.
4.2.2 Clip Event Monitor
A clip detector is provided each channel. These monitors will indicate any clip condition
(> 0.05% distortion) in the amplifier channel. The clip detectors also can indicate certain
errors (See Section 4.2.17).
