Networked PIP Series
5.2 Features of All Three Modules
The exact location of the following controls varies with the software. These features might be
inaccessible from the standard control panel, but accessible from a custom control page.
5.2.1 User Presets
The control settings for all the functions can be stored as presets. A total of ten presets can be
saved in the PIP’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.
5.2.2 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 4.2.18).
5.2.3 Input Signal Level Monitor
The input signal level of each channel can be monitored. The measurement range is from
+20dBu to -40dBu with 0.5dBu resolution. Each audio channel has the following monitors:
• Analog Audio Input: The audio input at the Balanced Audio Inputs of the PIP's front
panel.
• Switched Audio Input: The audio input after the Input Audio Router.
• CobraNet Audio Input (USP3/CN only): The audio input level from the selected
CobraNet audio channel.
5.2.4 Output Signal Level Monitor
The output signal level of each channel can be monitored. The measurement range is from 0
dB to –40 dB with 0.5 dB resolution. The monitors are scaled so that 0 dB is referenced to the
full rated output voltage of the amplifier. In Com-Tech
®
amplifiers the scaling can be changed
between the rated 70V output and the rated 8-ohm level. For all other amplifier models, the
scale is set to the rated output level.
5.2.5 Thermal Headroom Level Monitor
The thermal headroom level of each channel can be monitored with the software. This level
represents the percent of available power/thermal capacity that is currently being used within
the output section of the amplifier. When the thermal headroom level reaches 100%, the
amplifier cannot produce any more power and it will begin to protect the output devices by
limiting their drive level. The thermal limiter feature of the PIP can be set to engage at a pre-
selected thermal level. (See Section 5.2.19.)
5.2.6 Power/Standby Control
Each channel can be independently turned on and off.
5.2.7 Signal Mute
The output signal of each channel can be independently muted. This function produces 60 dB
or more of attenuation.
