For additional information, please con- sult Crown Tech Support, your system installer or retailer. We strongly recommend that you read all instructions, warnings and cautions contained in this manual.

    During operations of the switch, the Data indicator flashes as an aid to the user. See Section 4.1.8. D. IQ Data Indicator Flashes when the IQ-PIP-Lite receives a valid TCP/IQ command that is addressed to the IQ-PIP-Lite. See Section 4.1.1. E.

  • Page 11: Installation

    The IQ-PIP-Lite comes ready to install in the amplifier. This unit does not require setting the “IQ address” as the older current loop, Crown bus, units did. Each IQ-PIP-Lite (as well as all TCP/IQ components) come preprogrammed with a unique network (MAC) address. The IQ address is then set (automatically or manually) via the IQ control software.

    Figure 3.1 Installing the IQ-PIP-Lite Into the Amplifier page 12 3.3 Install the IQ-PIP-Lite Into the Amplifier Carefully ground yourself to the chassis of the amplifier before installing the IQ-PIP-Lite. It is a good idea to maintain ground contact between yourself and the amplifier while inserting the mod- ule into the amplifier.

    RX pairs switched) to set up the PIP module for desired operation. 2. Connect the audio input wiring. The IQ-PIP-Lite module is equipped with removable bar- rier block connectors for each channel’s input. See Section 5.1 for more detail on audio wiring.

  • Page 14: Operation

    IQ-PIP-Lite 4 Operation With an IQ-PIP-Lite module, a Crown PIP2 amplifier can be monitored and controlled from a remote location through the use of an IQ system. The PIP module features SmartAmp capabilities that enable the amplifier to function automatically. For example, the IQ-PIP-Lite can automatically turn off the high voltage supplies of the amplifier when no input signal is present.

    Ethernet network. Connection is made using a standard CAT 5 cable to a network switch port. In cases where an IQ-PIP-Lite is used in stand-alone mode (not connected to an network) it can be configured using a twisted cable (TX and RX pairs swapped) directly to a computer’s network adapter port.

    • Manual mode: The output is simply controlled with a command from the IQ software. • Error reporting mode: The AUX out is active when the IQ-PIP-Lite detects an error. Each error source (Thermal, Clip, Load, Amp Fault, and Line Voltage) can be individually enabled to activate the AUX output when the error conditions are met.

    The host amplifier’s mode status — Stereo (Dual), Bridge-Mono, or Parallel-Mono — can be sent to the IQ-PIP-Lite with this control. IQ software then becomes aware of the ampli- fier's mode and the IQ-PIP-Lite then ignores many of the Channel 2 controls. The actual mode of the amplifier cannot be controlled by this function.

  • Page 20: Auto Standby

    IQ-PIP-Lite 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 4.2.25 for instructions on setting up load monitoring. 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.

    IQ-PIP-Lite greater of the two input signals will be used as stimulus for both compressors. Each com- pressor will still compress based on its individual threshold, attack, release and ratio set- tings. 4.2.20 Peak Voltage Limiter This limits the peak voltage output of the amplifier. Four parameters control this limiter for each channel: Enable: Enables or disables this function.

    4.2.25 Load Supervision The load supervision feature allows real-time monitoring of the load connected to each amplifier channel. When enabled, the IQ-PIP-Lite continuously monitors the amplifier output voltage and current, and calculates the long-term average load impedance. The measured load impedance is compared against the user-defined high and low limits. If either limit is exceeded, the status indicator and, if enabled, the IQ System Error Reporting functions alert the user of the problem.

    • Turn the entire sound system off before changing any connections. Turn the level con- trols down before powering the system back up. Crown is not liable for damage incurred when any transducer or component is overdriven.

  • Page 24: Tcp/Iq Network Basics

    IQ-PIP-Lite 5.2 TCP/IQ Network Basics TCP/IQ is a network based protocol that has the ability to control and monitor IQ compo- nents over a common TCP/IP network. For IQ components that have CobraNet capability, TCP/IQ has the ability to control and monitor these IQ components over the same Ethernet network used for CobraNet audio, resulting in a single CAT-5 connection for control, moni- toring, and digital audio.
  • Page 25 IQ-PIP-Lite Some of the features of TCP/IQ include: • Real-time control and monitoring of IQ components. • Use of standard “off-the-shelf” Ethernet technology. • For CobraNet enabled components, a single connection for both control and CobraNet audio. • Ability to quickly discover all IQ components connected to the network.

  • Page 27 IQ-PIP-Lite four numbers (0-255) separated by periods. For example, a subnet mask of 255.255.255.0 and an IP address of 192.168.1.123 says that all IP address in that LAN are in the IP address range of 192.168.1.1 to 192.168.1.255. If a TCP/IQ controller is on a different network than the TCP/IQ components, communica- tions must occur through an IP router.

  • Page 28: Advanced Features And Options

    6 Advanced Features and Options 6.1 Using the AUX Connector The AUX connector of the IQ-PIP-Lite offers a means to tap some of the flexibility of the IQ System. It can be used to enable peripherals, send a signal to another system component, and send a line-level audio signal of the amplifier's output.
  • Page 29 IQ-PIP-Lite The AUX output has two enhanced modes: Error Reporting and Flash Preset. In Error Reporting mode, the AUX port can be set up to change state when any selected error (clip, thermal, amp fault, load impedance, and AC line level) is detected. With this feature, the AUX output of each amplifier can be wired to a separate light on a panel at the control loca- tion to indicate whether the amplifier is or is not in error.

    6.2 Load Supervision Applications The IQ-PIP-Lite Load Supervision feature can be used to monitor the amplifier load in real time with almost any program material. Average load impedance is calculated as a function of amplifier output voltage and current.

    The low frequency variations are usually wide bandwidth and may vary from 6 to 30 ohms on an 8-ohm driver. These anomalies are easily averaged out by the IQ-PIP-Lite supervision algorithm in most systems. However, there may be some extreme situations for very narrow bandwidth (i.e.
