PREFACE : ABOUT THIS DOCUMENT This guide will take you through the installation process of all Constellation components, in preparation for the calibration tuning phase. Each component has unique requirements for power, audio signal, and best wiring practices. Follow all of the guidelines in this manual to guarantee the highest-quality sound for your venue.
CHAPTER 1: POWER REQUIREMENTS The type, quality, and correct connection of the electrical system that will be used to supply power to the Constellation system is very important. The effect of poor, inadequate, or low-quality power will have a detrimental result in the sound quality of the system. The following information is the Meyer Sound specification for proper powering of the various components of a Constellation System.
CHAPTER 1: POWER REQUIREMENTS or mechanical ground system or the Constellation electrical systems’ chassis or mechanical ground. This will prevent the “shorting” of the Constellation system’s isolated ground system. Equipment Rack Power The equipment racks for the loudspeaker power supplies and Constellation processors should be isolated from any other conductive material and connected directly to the isolated ground.
CONSTELLATION INSTALLATION GUIDE Power Specifications It is important to make sure that each powered component receives the required amount of electrical power. Matrix3 Processors The Matrix3 Constellation processors require 200 watts maximum per unit. Stella-188 Power Supply The Stella-188 Power Supply can supply power for up to 16 Stella-4 loudspeakers, or 8 Stella-8 loudspeakers. Current draw: Burst Current (<1 sec) 5.2 A rms (115V AC), 3 A rms (230 V AC), 6.
CHAPTER 1: POWER REQUIREMENTS MPS-488P Power Supply The MPS-488P Power Supply can supply power for up to 8 MM-4XP loudspeakers, through 5-pin Phoenix connectors. Current draw: Burst Current (<1 sec) 15 A rms (115 V AC), 7.5 A rms (230 V AC) Multiple power supplies should be installed in the rack with no empty spaces between them. The power ratings for all Meyer Sound products can be found online at http://www.meyersound.com, listed by individual product.
CHAPTER 2: WIRING INSTALLATION The installer should be a recognized experienced local installer with a good track record of previous related installations. Meyer Sound does not authorize companies for product installation; however, Meyer Sound expects all installation companies to follow universal standards set out by NSCA, NAB, and other universally accepted standards. Conduit When installing Constellation wiring, be sure to use the NSCA or similar guide lines for installation of low voltage wiring.
CHAPTER 2: WIRING INSTALLATION MM-4XP Cabling The MPS-488(E/P) MM-4XP power supply provides both audio signal and power to the MM-4XP loudspeakers. To connect the signal conducts of the Belden 1502 cable to a Phoenix connector: 1. Follow insulation stripping lengths. 2. Connect the shield to pin one at both ends of the cable. Do not “lift” the ground conductor at either end. 3. When stripping insulation do not nick the insulation of individual conductors. 4. Completely remove any exposed foil shield. 5.
CONSTELLATION INSTALLATION GUIDE Polarity Polarity must be maintained between all microphone and loudspeaker cables. Follow the “pin two is hot” standard for wiring balanced lines. Maintain continuity of shields at all connecting points, except as required by standard specified practice for “floating” shields.
CHAPTER 3: LOUDSPEAKER LOCATIONS AND INSTALLATION Loudspeaker Locations and Installation Loudspeaker placement will be specified in the Constellation system design. The Meyer Sound representative will provide plans showing the exact placement of each loudspeaker and microphone within the venue.
CHAPTER 3: LOUDSPEAKER LOCATIONS AND INSTALLATION Hanging an MM-4XP from a pipe may require an all-thread extender.

CONSTELLATION INSTALLATION GUIDE Loudspeaker Installation One of the things that makes the Constellation system sound so natural is that it regenerates the physical acoustics of a room. As a consequence, the resulting quality of a Constellation system is dependent on the quality of the physical acoustics of the space. Make sure all mounts for loudspeakers are secure, tight and free from buzzes, rattles, and acoustic distortion. Isolate with rubber mounting where necessary.
CHAPTER 4: MICROPHONE LOCATIONS AND INSTALLATION Microphone Placement As with the loudspeaker locations, each microphone’s location is specified by the Constellation system design. If there are conflicts in any drawings or field locations due to other equipment, please notify Meyer Sound and your consultant immediately with those conflicts so the issue may be resolved.
CHAPTER 4: MICROPHONE LOCATIONS AND INSTALLATION The miniature omni microphone looks like this: The compact cardioid microphone looks like this: The XLR connector that terminates these microphones has a barrel that is approximately 3" long.
CONSTELLATION INSTALLATION GUIDE Dimensions of the miniature capsules are shown below: Miniature Cardioid Miniature Omni A shock mount is available for the compact cardioid.
CHAPTER 4: MICROPHONE LOCATIONS AND INSTALLATION Microphone Installation Make sure all mounts for microphones are secure and tight. Use rated materials wherever possible. Try to maintain as much distance as possible from electrical equipment and fixtures, without modifying the microphone placement guidelines. Be aware of large transformers, as well as high voltage lighting instrument locations. These devices may still have an impact on the performance of the microphones.
CONSTELLATION INSTALLATION GUIDE isolation of the ground paths from one another as well as connection to the chassis of the patch box. ■ Multi-core/snake cables need to be be the type that has separate jackets or insulation for each pair. A multi-core/snake cable that uses a foil shield with Mylar, or similar types of material, covering the foil shield are not acceptable.
CHAPTER 5: CONSTELLATION PROCESSOR INSTALLATION Constellation processors should be mounted within a rack in an equipment room near the venue. Each processor comes with an IEC power cable and a link cable, and each system includes one null modem serial cable. It is recommended that you prefabricate and build as much of the Constellation system racks as possible, so that you are able to load the software and pretest the processors before they are installed on site.
CHAPTER 5: CONSTELLATION PROCESSOR INSTALLATION 1. All MS-CONSTELLATION processors. These processors include an LX-ELC module and an LX-COS module. 2. All MS-VRAS processors. These processors include an LX-VRA module in place of an LX-EXP module. 3. All MS-EXPANSION processors. These processors have two LX-EXP modules, and do not have either an LX-ELC module or an LX-COS module.
CONSTELLATION INSTALLATION GUIDE Linking Processors All processors must be linked together in a ring configuration. Each processor has two link connections, labeled "NEXT" and "PREVIOUS". As mentioned above, each processor comes with a 3' link cable. Each system will also include one longer link cable, for linking the first and last processor. The "NEXT" port on the top processor should be connected with a link cable to the "PREVIOUS" port on the processor directly beneath it.
CHAPTER 5: CONSTELLATION PROCESSOR INSTALLATION Network Connections A network connection to the MS-CONSTELLATION processor is required for tuning purposes, and may also be required by system control devices. Connect a CAT5 or CAT6 cable between the network switch and the LX-ELC module on the MS-CONSTELLATION processor. The processor will be pre-configured with a default IP address of 192.168.0.101. No DHCP is needed for the Constellation system network.
CHAPTER 6: SYSTEM CONTROL OPTIONS Once the Constellation system is installed and tuned, the client must have a way to easily select Constellation settings. For this purpose, there are several options: Web Page Control This option requires a minimum amount of extra equipment, as the client only needs access to a web browser on a computer that is networked to the Constellation system.
CHAPTER 7: INITIAL SYSTEM TESTS As a Constellation installer, you will be required to do some initial testing of the system, as directed by an authorized Constellation representative. All testing should be completed well in advance of the Constellation tuning dates so that any outstanding issues can be resolved before the tuning process begins. It is always best to check each cable for damage as the cable is being pulled, before other equipment is installed.
CHAPTER 7: INITIAL SYSTEM TESTS 4. In the Configuration menu, select Query Hardware for Configuration... A dialog box will appear, listing out the number of processors it has detected. Click Accept. 5. In the Configuration menu, select Send Configuration to Frames. This sets up the correct number of inputs and outputs, and sets all mixer settings to default. See the CueStation User Guide for more information about configuring your Constellation system, including CobraNet, DSP allocation, and output types.
CONSTELLATION INSTALLATION GUIDE 10. Open the Output Masters window, and mute or unmute each output as desired to verify signal at each loudspeaker. Using Wild Tracks as a Signal Source For installations where it is impractical to connect an external audio signal for loudspeaker testing, you may choose to use Wild Tracks as a signal generator. 1. Open the Mixer Configuration window, and click on Frame 1. The modules for the first Constellation processor will appear in the window. 2.
CHAPTER 7: INITIAL SYSTEM TESTS 3. In the box directly above the output channel number, it is labeled "Output". Click on the Up arrow next to the box to change the output type to "PFL M". 4. In the Configuration menu, select Send Configuration to Frames. The output channel has now been re-configured as a mono PFL channel. 5. Open the Inputs window. In the top left corner of the window, click the button labeled "Unlock +48v". This will allow you to turn on phantom power for each microphone input channel. 6.
