IQ-PIP-USP3/CN
• CobraNet with Analog Backup: This allows the use of the Balanced Audio Inputs to
be used as backup to the CobraNet audio should the network's audio be lost for any reason.
In this mode, the USP3/CN will sense the loss of the CobraNet audio and will automatically
switch to the chosen Balanced Audio Input until CobraNet network audio returns.
• CobraNet with Analog Override: If an external emergency override of the CobraNet
audio is required, this mode will allow the automatic switching of the Balanced Audio Input
over the CobraNet audio input if a signal is noticed on the Analog Input. When the Emer-
gency Override is completed, the CobraNet audio will be routed to the channel after 10 sec-
onds.
4.2.11 Dynamic Gain Monitors (Ghost Faders)
These indicators let the user monitor the actual signal path gain. The actual gain may vary
from the input attenuator settings as a result of compression and limiting. On standard IQ
software control panels, these indicators appear as flying ghost faders behind the input
attenuator controls.
4.2.12 Amplifier Information
At startup, the IQ-PIP-USP3/CN extracts several useful items of information about the host
amplifier. These include manufacturer, model, date code, and serial number. This informa-
tion is stored in the IQ software system inventory and is displayed on the software control
panels.
4.2.13 User and Channel Labels
The IQ-PIP-USP3/CN can store two user labels and two channel labels. These labels are
30-character strings that can be set by the user to indicate the function of the amplifier and
its channels.
4.2.14 Amplifier Mode
The host amplifier’s mode status — Stereo (Dual), Bridge-Mono, or Parallel-Mono — can
be sent to the IQ-PIP-USP3/CN with this control. IQ software then becomes aware of the
amplifier's mode and the IQ-PIP-USP3/CN then ignores many of the Channel 2 controls.
The actual mode of the amplifier cannot be controlled by this function. The amplifier mode
must be selected with the switch located on the amplifier rear panel.
4.2.15 Amplifier Output Mode
On Com-Tech series amplifiers, the output mode (70V or 8-4 ohm) should be set on the IQ-
PIP-USP3/CN with these controls. This allows the PIP to scale its output meters appropri-
ately and lets the IQ software become aware of the settings. The actual mode of the amplifier
cannot be controlled by this function. The amplifier output mode, for each channel, must be
selected with the switches located on the rear of the amplifier.
4.2.16 Line Voltage Monitor
The AC line voltage supplied to the amplifier can be monitored with this function in the CTs
series of amplifiers. This function is NOT supported in any other amplifier.
4.2.17 Error Reporting
The IQ-PIP-USP3/CN can detect four different error conditions per channel and errors in
the AC line voltage. Each error type can be individually configured to report the error
through the IQ network and/or the AUX port. Network reported errors appear in the IQ Sys-
