Networked PIP Series
5.1.7 CobraNet In-Use/Conductor Indicator (USP3/CN only)
The indicator on the left side of each CobraNet RJ-45 connector turns ON if the port is in-
use (i.e. the link is being used to transmit or receive active CobraNet traffic), and will blink
if the device is also the conductor (the timing reference).
5.1.8 Balanced Audio Inputs
This removable barrier block connector allows line level audio signals to be input to the
PIP. The PIP-Lite and PIP-USP3 use two 3-pin connectors (one per channel), while the
PIP-USP3/CN uses one 5-pin connector that handles both channels. The USP3/CN
accepts line level analog audio signals in addition to the digital audio that is available
through the CobraNet network. In the USP3/CN, this analog audio can be used for one of
three purposes:
• 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 override signal would be required of the entire
system, the USP3/CN would automatically sense the presence of the 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 converting the Balanced Audio Inputs to CobraNet.
5.1.9 Aux Input/Output Connector
An RJ-11 connector provides three functions: AUX output, AUX input and Listen Bus. Ana-
log Listen Bus or foldback is not available in the PIP-USP3/CN. The AUX output is a mul-
tifunctional control output that delivers 15 VDC limited to 15 mA. It can be configured 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 PIP detects an error. Each error
source (Thermal, Clip, Load, Amp Fault, and Line Voltage) can be individually 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 PIP makes no changes to its operation. However, the AUX input
status can be monitored through the IQwic software and used for functions within the soft-
ware.
• 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.
