tem Error Window. The IQ software offers many options to further report errors, including
audible alerts, printout, email, pager, serial port and fax. The following describes each error
source.
CLIP: The PIP can be configured to report if an excessive number of clip events occur in
either amplifier channel. The clip events are consider an error if they exceed the defined
count per the defined unit of time. The
Count Control sets the maximum number of events
before the error is reported. The range is 1 to 100. The Time Control defines the amount of
time that the events are counted before starting the counting process over. Its range is 1 to
10 seconds. Note: Clip events are defined as the start of each clip and every 10
milliseconds the amplifier is in clip thereafter. Using a high count setting with a short time
setting may result in clip error never being detected.
THERMAL: Errors can be generated for excessive temperature in the output section of the
amplifier channel. The Threshold Control sets the level that, if exceeded, will generate the
error report. This control has a range of 1 to 100%.
FAULT: Some PIP2-compatible amplifiers provide a fault signal to the IQ-PIP-USP3/CN if
it detects some catastrophic amplifier failure.
LOAD: If the load monitoring feature is activated, an error report can be generated if the
load impedance falls outside the pre-selected range. See Section 4.2.29 for instructions on
setting up load monitoring.
LINE VOLTAGE: On the CTs series of amplifiers, the AC line voltage can be monitored and
an error generated whenever the voltage is outside of the limits set by the software.
4.2.18 Auto Standby
The Auto Standby feature automatically turns off either amplifier channel when no audio
input signal has been detected for a period of time. The channels are controlled indepen-
dently. There are three parameters which control this feature for each channel:
Enable: Enables or disables this feature.
Input Gate Level: Sets the level, in dBu, below which the high-voltage supply of an
amplifier channel will be turned off. The range is from +16 dBu to –40 dBu.
Turn-Off Delay: Sets the time, in minutes, that the input signal must remain below the
gate level before the channel will be disabled. The range is from 0 to 255 minutes. A setting
of zero is provided to facilitate the setup of the input gate level.
4.2.19 Input Signal Compressor/Limiter
An input signal compressor/limiter is available for each channel. Five parameters control
this feature:
Enable: Enables or disables this function.
