I-Tech HD Series Power Ampliﬁers

4 Advanced Operation

4.6 Digital Audio Options (AES/EBU)

Digital audio inputs allow you to keep the ampliﬁ er input signals in the digital domain. Keeping the input signal digital reduces the number of Digital-to-Analog and Analog-to-Digital conversions. This provides better sound quality and reduces pickup of electrical interference.

The AES/EBU connector provides the most widely accepted format. Connect an AES/EBU signal to the AES/EBU connector on the rear panel. If the ampliﬁ er’s low-voltage power supply is lost for any reason, the AES input signal goes directly to the AES output. The ampliﬁ er has a digital buffer converter so it will adapt to any AES sample rate between 32 and 96kHz that is sent to it.

4.7 Networking the Ampliﬁer

If you need help understanding network concepts, please see Appendix A on Network and CobraNet Basics. Please check the System Architect help ﬁ le for directions on how to use its networking conﬁ guration tools.

An I-Tech HD ampliﬁ er may be used in an existing I-Tech network and can use existing I-Tech device or venue ﬁ les.

You can make the following settings via the front panel or by using the Network Troubleshooter:

HiQnet node address DHCP off/on

IP address Subnet mask

You cannot set the CobraNet IP address via the front panel.

4.7.1 Network Troubleshooter

The network troubleshooter can assist you in setting up your HiQnet network for the ﬁ rst time. Using the troubleshooter, 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. It will not work through a router.

Select Network Card

The ﬁ rst page of the wizard lists all the network adapters currently in the computer. If you have more than one adapter, you can scroll through the list and see the IP Address assigned to each card.

If you have a card with an IP address of 0.0.0.0, it typically means one of several things:

1.The card is disabled.

2.The card is not connected to a network.

3.The card is setup to obtain its address from a DHCP server, and no DHCP server is available.

Select the card that is connected to the HiQnet system and click the Next button. The Wizard will walk you through the rest of the process. Please see the System Architect online help for more information.

4.8 Software-Controllable Onboard DSP

Crown’s latest-generation Digital Signal Processing is built into the I-Tech HD ampliﬁ er. Its 24-bit/96kHz converters offer extremely low noise and extended dynamic range. When you use an I-Tech HD amp, the loudspeaker processors, crossovers, limiters and delays are in the onboard DSP – so you don’t need those rack-mounted devices. This drastically cuts setup time, commissioning, rack space and costs.

The I-Tech HD’s DSP can be monitored and controlled with a computer running System Architect software, and connected to the ampliﬁ er Network Connector by a network Category 5 cable.

Some applications for this DSP are:

•Set up signal ﬂ ow

•Optimize system gain structure

•Set up speaker conﬁ gurations (set the drive levels, frequency bands, delays and limiting for your particular speakers)

•Set up EQ, ﬁ ltering, compression, and much more.

The next several pages explain some of the available DSP functions. See the System Architect Help ﬁ les for more detailed information.
