    *A PIP2-compatible amplifier is necessary to use these PIP modules. To determine if the amplifier is PIP2 compatible, look for the with older Crown PIP amplifiers (except the PIP-Lite if a USP2 adapter is first installed in the amplifier. See Section 9 for more detail on the USP2 adapter.) Note that the PIP-Lite and PIP-USP3 cannot receive or transmit CobraNet audio.

    The PIP 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 PIP (as well as all network components) comes preprogrammed with a unique network (MAC) address. The IQ or HiQ- net address is then set (automatically or manually) via the IQwic or SystemArchitect control software.

    Networked PIP Series 4 How to Set Up TCP/IP 4.1 Introduction Before you set up a TCP/IP network with addressing, it’s important to understand all the terms involved. The following glossary explains network terminology. 4.1.1 Glossary Network: A group of interconnected components, such as a central computer, network switching equipment, and other computers or devices.

For a stand-alone system, Crown has provided a worksheet of a tested configuration later in this section. DHCP (Dynamic Host Configuration Protocol): This a protocol for automatically assigning IP addresses to devices on a network.

  • Page 21: Tcp/Ip Addressing Rules

    Networked PIP Series 4.2 TCP/IP Addressing Rules In the next section, you will be assigning static TCP/IP addresses to the devices in your network. When you do so, be sure to follow the addressing rules below. Otherwise, the computer may not communicate with the devices. 1.

    Networked PIP Series 4.3 Network Setup Wizard The network setup wizard can assist you in setting up your network for the first time. Using the wizard, you can address your components and be informed of addressing and other errors in the system. Please note that this wizard is designed to work with devices that are on the same physical network segment as the computer it is running on.
  • Page 23 The wizard is able to avoid assigning IP addresses used by other Crown or Harman compo- nents, but it cannot detect if it has assigned an address that is currently being used by another computer or TCP/IP device on the network.

Crown strongly recommends the use of switches and not hubs in the implementation of the CobraNet network. Use of hubs will limit the amount of CobraNet traffic that can reside on the network and create unnecessary limitations in the network.

    This removable barrier block connector allows line level audio signals to be input to the PIP. The PIP-Lite and PIP-USP3 use two 3-pin connectors (one per channel), while the PIP-USP3/CN uses one 5-pin connector that handles both channels. The USP3/CN accepts line level analog audio signals in addition to the digital audio that is available through the CobraNet network.

    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.

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.

  • Page 32: Input Signal Compressor/Limiter

    Networked PIP Series 5.2.18 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. Threshold: Sets the level, in dBu, above which the compressor begins to attenuate the input signal.

  • Page 33: Average Power Limiter

    Networked PIP Series Release Time: Sets the release time of the compressor. The release time is defined as the time it takes the limiter to increase the output signal by 20 dB. The range is from 10 milli- seconds to 10 seconds. 5.2.20 Average Power Limiter This limits the long-term output power of the amplifier.

  • Page 34: Load Supervision

    Networked PIP Series 5.2.24 Load Supervision The load supervision feature allows real-time monitoring of the load connected to each amplifier channel. When enabled, the PIP 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.

  • Page 35: Typical Load Characteristics

    Networked PIP Series Most amplifier/load systems can be configured and supervised by following these steps: 1. Configure your audio system using a known “good” load, then enable the Load Supervi- sion feature. 2. Provide typical program material at a level high enough to light the “test” indicator. 3.

  • Page 36: Pip-Usp3 And Pip-Usp3/Cn Features

    Networked PIP Series These anomalies are easily averaged out by the PIP supervision algorithm in most systems. However, there may be some extreme situations for very narrow bandwidth (i.e. single-note) signals and/or very widely varying loads that the algorithm simply cannot overcome. In these cases, widening the high and low limits will help decrease the “sensitivity”...

  • Page 38 The SLM tab allows you to test network-PIP components for impedance vs. frequency and frequency response. The USP3 and USP3/CN include a signal generator to provide a swept sine-wave signal for the tests. Described below are the three sections of the SLM tab: Sweep, Channel SLM and Tolerance.

    Networked PIP Series 6.2 Network Basics HiQnet and TCP/IQ are network based protocols that have the ability to control and monitor networked components over a common TCP/IP network. For components that have Cobra- Net capability, HiQnet and TCP/IQ have the ability to control and monitor these compo- nents over the same Ethernet network used for CobraNet audio, resulting in a single Category-5 connection for control, monitoring, and digital audio.

Today, commonly available networking cards are 10/100Base-T capable, which allows them to be used on either 10BaseT or 100Base-T networks.

  • Page 51: The Conductor

    Networked PIP Series The usual assignment is 8 channels at 20 bits. You can use fewer channels per bundle, but maximum size bundles are suggested for the most efficient use of network bandwidth. If 24- bit data is desired, then only 7 audio channels can be loaded into a single Bundle. In IQwic, you create audio connections between sending devices (transmitters) and receiv- ing devices (receivers).

  • Page 52: Switched Networks

    Networked PIP Series 6.3.6 Switched Networks A more complex CobraNet network can be built using Ethernet switches. Switches do not simply broadcast each and every packet to all nodes. Instead, they check each incoming data packet to determine its destination and (very quickly) transmit the data to only that des- tination port.

    The AUX connector offers a means to tap some of the flexibility of the Harman Pro System Architect or Crown 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.

    This input can be a temperature sensor, door closure switch, or operator pushbut- ton. It can be used by the IQ software to change configuration settings on any or all system devices. See the Harman Pro System Architect or Crown IQ System Help files for exact information.
