ASTi Crown® Power Amplifier User Guide (Ver. 1, Rev. F) Chapter 1: Introduction The Crown® Power Amplifier provides the user with the power to drive passive audio loudspeakers. Each amplifier is a network component that integrates with ASTi’s ACENet. ACENet provides a low latency, network based audio and I/O distribution architecture for ASTi’s Telestra 4 ACE communications and sound modeling equipment and software. The amplifier offers a full range of indicators for accurate diagnostics.

ASTi Crown® Power Amplifier User Guide (Ver. 1, Rev. E) Chapter 2: Getting Started WARNING: Before amplifier installation, ensure that your amplifier is not connected to power and all control levels are turned down (counter clockwise). 2.1. Proper Cooling Do not block any of the amplifier ventilation vents. When using an equipment rack, mount the units directly on top of each other. Do not block rear, front, or side air vents. The side walls of the rack should be a minimum of two inches (5.
ASTi Crown® Power Amplifier User Guide (Ver. 1, Rev. F) 2.2. ACENet and Crown Power Amplifier Operation and Configuration Process Each power amplifier connected to a Telestra 4 Target forms part of the ASTi networked ACENet audio distribution architecture, and hence behaves a little differently from a simple analog power amplifier at start-up.
ASTi Crown® Power Amplifier User Guide (Ver. 1, Rev. E) ASTi recommends that users limit themselves to the basic operation of the Crown power amplifiers, however we do recognize that there are many sophisticated capabilities available within the embedded functionality of the amplifiers via the Crown HiQnet. Please contact ASTi before attempting to utilize any of the extended features of these amplifiers to ensure that there is no conflict with required ASTi configuration settings.
ASTi Crown® Power Amplifier User Guide (Ver. 1, Rev. F) 2.2.1. Multiple Crown Amplifiers on the ACENet All Crown amplifiers come pre-configured with the same IP address and when using two or more on the same ACENet network they will not function properly in the System Architect software until one IP address is changed. ASTi recommends changing all IP addresses if using multiple Crown amplifiers on the same ACENet network.
ASTi Crown® Power Amplifier User Guide (Ver. 1, Rev. E) 2.3. Setup Procedure 1. Connect the power cord into the AC Power Cord Connector. 2. Remove the Output Connector’s cover plate and connect the speakers to the output connectors. 3. The dual RJ45 connectors allow a Primary & Secondary Ethernet port to the 100 Mbps Ethernet network. Use the Primary or Secondary port and a Category 5 cable to connect to the ACENet switch. 4.
ASTi Crown® Power Amplifier User Guide (Ver. 1, Rev. F) 2.4. Powering Up the Amplifier Important: Complete section 2.1. Setup Procedure before proceeding with this section. When turning on the amplifier for the first time follow the steps below. 1. Turn down the levels of the audio source. 2. Turn on the Power switch. The power indicator should illuminate. 3. Turn up the audio source levels. 4.
ASTi Crown® Power Amplifier User Guide (Ver. 1, Rev. E) Chapter 3: General Information 3.1. Front Indication Lights • Bridge Mode Indicator – illuminates yellow when the channel pair is set to the “Bridge” position. If the bridge mode is changed while the amplifier is powered on it must be powered off and back on to reset the mode. • Ready Indicator – illuminates green when the channel is initialized and ready to produce audio output.
ASTi Crown® Power Amplifier User Guide (Ver. 1, Rev. F) 3.2. Rear Panel Connections Caution: Manual selection of a ‘preset’ (via the rear panel ‘preset’ switch) will almost certainly cause the amplifier to cease communication with the Target (since the required ACENet configuration data will not be available in the selected preset).
ASTi Crown® Power Amplifier User Guide (Ver. 1, Rev. E) • Channel Level Controls – act as the overall master gain control for each channel in all operational modes. The exact setting required for any specific installation will depend on a number of factors including speaker placement, speaker sensitivity, size of the space being driven, and of course the required sound level required from the system.
ASTi Crown® Power Amplifier User Guide (Ver. 1, Rev. F) Chapter 4: Technical Specifications 4.1. Wiring Select the appropriate size of the wire based on the distance from the amplifier to the speaker. Distance Wire Size up to 25 ft. (7.6 m) 16 AWG 26-40 ft. (7.9-12.2 m) 14 AWG 41-60 ft. (12.5-18.3 m) 12 AWG Over 60 ft. (18.3) 10 AWG Warning: Never connect the speaker return to the chassis of the amplifier, or damage to the amplifier may result. Never use shielded cable for output wiring.
