IQ-PIP-USP3/CN
page 16 Reference Manual
• Backup of the CobraNet Network audio: In the unlikely event of a loss of CobraNet
audio to the USP3/CN, the module would automatically switch over to the Balanced Audio
Inputs.
• Emergency Override: If a hardwired emergency override signal would be required of
the entire system, the USP3/CN would automatically sense the presence of the Emergency
Override Signal at the Balanced Audio Inputs and switch to that signal.
• CobraNet Network Audio Inputs: Each USP3/CN can act as a CobraNet audio Input
source by providing the Balanced Audio Inputs to the CobraNet network.
While the processing of the entire digital audio within the USP3/CN is full 24 bit, these Bal-
anced Audio Inputs are limited to 18 bits and should be used as a secondary source of
audio integration and not used for the primary audio performance path.
4.1.7 Aux Input/Output Connector
An RJ-11 connector provides two functions: AUX output and AUX input. The AUX output
is a multifunctional control output that delivers 15 VDC limited to 15 mA. It can be config-
ured in three modes:
• Manual mode: The output is simply controlled with a command from the IQ software.
• Error reporting mode: The AUX out is active when the IQ-PIP-USP3/CN detects an
error. Each error source (Thermal, Clip, Load, Amp Fault, and Line Voltage) can be individ-
ually enabled to activate the AUX output when the error conditions are met.
• Flash preset mode: The AUX output can be configured to flash the preset number like
the front panel indicator.
An inversion control allows the AUX output functionally to be inverted for the manual and
error reporting modes. The inversion control is ignored for flash preset mode.
The AUX input is a two-state input with a high state defined as voltage between 4 and 15
VDC. The low state is defined as voltages between 0 and 1.6 VDC. It has a 10K input
impedance. The AUX input can be configured in several modes:
• None: In this mode the IQ-PIP-USP3/CN makes no changes to its operation. However,
the AUX input status can be monitored through the IQ software and used for functions
within the software.
• Mute Channel 1, Mute Channel 2, and Mute both functions each mute their
respective channels when the AUX input is active. Likewise, the Power Channel 1,
Power Channel 2, and Power Off Both functions disable the respective channels dur-
ing an active AUX input.
• The cycle preset mode will advance the IQ-PIP-USP3/CN 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.
