Networked PIP Series

5.2.8 Polarity Inverter

The input signal polarity of each channel can be independently inverted.

5.2.9 Input Signal Fader

Each input signal can be adjusted under software control. The gain range is +20dB to
–80dB in 0.5dB steps. In addition to adjustment of the post input router signal, each Analog
Audio Input has a separate Fader that allows the trim of the Analog Audio Input before the
Input Router.

5.2.10 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 IQwic
software control panels, these indicators appear as flying ghost faders behind the input atten-
uator controls. System Architect has separate gain-reduction meters.

5.2.11 Amplifier Information

At startup, the PIP extracts several useful items of information about the host amplifier. These
include manufacturer, model, date code, and serial number. This information is stored in the
software system inventory and is displayed on the software control panels.

5.2.12 User and Channel Labels

The PIP 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. For
example, "LOWER RIGHT CLUSTER, FOR DELAY."

5.2.13 Amplifier Mode

The host amplifier's mode status — Stereo (Dual), Bridge-Mono, or Parallel-Mono — can be
sent to the PIP with this control. IQwic then becomes aware of the amplifier's mode and the
IQ-PIP 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.

5.2.14 Amplifier Output Mode

On Com-Tech series amplifiers, the output mode (70V or 8-4 ohm) should be set on the PIP
with these controls. This allows the PIP to scale its output meters appropriately and lets the
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.

5.2.15 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. The amplifier line
voltage is displayed, and no user input is required.

5.2.16 Error Reporting

The PIP can detect four different error conditions per channel and errors in the AC line volt-
age. Each error type can be configured to report the error through the control network and/or
the AUX port. Network reported errors appear in the control software's Error Window.
