Reference Manual
Networked PIP Series
The software offer many options to further report errors, including audible alerts, printout,
email, pager, serial port and fax. The exact options vary depending if you are using System
Architect or IQwic. The options are set in the software. 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 PIP 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 moves outside the pre-selected range. See Section 4.2.29 for instructions on set-
ting up load monitoring.
LINE VOLTAGE:
In 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.
5.2.17 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 independently. It is
similar to an audio gate but it atenuates the power supply. 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 ampli-
fier 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.
Power-On Delay Control
: This control multiplies the addresses by a time offset to provide
sequencing of power-on in the amplifiers. So if you apply power to the entire rack at once,
and this feature is engaged, the amplifers will come on in series based on their addresses.
