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.
There are several main components to a Constellation system:
Constellation Processors
The Constellation processors provide all of the audio processing and signal routing functions
necessary for a Constellation system. The processors are typically rack-mounted in an
equipment room with other audio components. See Chapter 5, Constellation Processor
Installation (p. 21) for more information.
Constellation Loudspeakers
Constellation loudspeakers can be mounted directly on a surface or hidden within a
back-can. Your Constellation design will specify the exact number and type of loudspeakers
required for your venue's Constellation system. Loudspeaker installation instructions can
be found in Chapter 3, Loudspeaker Locations and Installation (p. 9).
Constellation Microphones
Constellation microphones are typically hung from the ceiling, or surface-mounted on a
wall or ceiling. Your Constellation design will specify the exact number and type of
microphones required, as well as their placement within the venue. Microphone installation
instructions can be found in Chapter 4, Microphone Locations and Installation (p. 15).
System Control
Each Constellation system will include a method for the client to select Constellation
settings. This may include a simple touchscreen mounted on a wall, a web page, or direct
control of the system through CueStation™software. Installing a control device may require
a network or serial connection to the Constellation processors. See Chapter 6, System
Control Options (p. 25) for more information.

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.
Building Power
A dedicated transformer or a balanced power transformer of adequate size for the Constellation
system shall be attached to the building power system. The ground conductor of the transformer
will be connected directly to the ground used by the building’s main service transformer. All of
the ground wires of the Constellation electrical system will be joined at the dedicated transformer.
An uninterruptible power supply should be placed in-line with the output of the transformer. It
should be of adequate size and type to provide enough current for an appropriate amount of
time to continue to meet the systems power needs in the event of power disruption to the input
of the transformer. Check with your electrical engineer to properly size this transformer.
At the grounding point of the ISO transformer, the chassis ground, or mechanical ground, the
isolated ground, and the neutral buss will be connected. The chassis or mechanical ground will
connect the sub-panels, conduit, enclosures, racks, etc.
The neutral bus, through the distribution and sub-panels, will be connected to the neutral
terminal of all electrical sockets or the neutral connector of equipment.
The isolated ground will NOT be connected to any electrical panel, conduit, or any other
conductor EXCEPT for the ground connection to a piece of equipment through its power supply
cord or directly to the chassis of the equipment.
The chassis of equipment connected to the isolated ground system shall not have contact with
any material that is connected to the chassis or mechanical ground. This includes structural
steel, aluminum studs, and non-isolated racks.
No microphones, loudspeakers, Constellation processors, computers, monitors, termination
blocks, XLR connectors, or any other equipment associated with the Constellation system can
come in contact with any conductive material that is attached to any of the building’s chassis
1
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.
Using a PVC connection box and rubber feet on your rack will isolate the power source and
keep the isolated power ground from touching common power ground.
Insulate all cables in the rack room from conduit and extraneous grounds. Do not tie the shell
of cable type microphone connectors to shield except within microphones themselves.
Connectors which utilize their shells as conductors for shield, i.e., 3-circuit phone jacks, shall
be insulated from their mounting plate.
Because of the great number of possible variations in grounding systems, it shall be the
responsibility of the contractor to follow good engineering practice, as outlined above, and to
deviate from these practices only when necessary to minimize crosstalk and to maximize
signal-to-noise ratios in the audio and control systems.
The electrical contractor, along with the system contractor, shall be responsible for confirming
that the technical ground is properly electrically bonded to the building technical ground system.
It is not acceptable to use wall plugs for the rack installation; always use AC distribution inside
the rack. Because electrical code may vary from state to state and country to country, always
check with your electrical engineer and the laws in your area for specific code requirements.

CHAPTER 1: POWER REQUIREMENTS
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. Use no wire tuggers please! Microphone cable, digital cable, and most
low voltage cabling can not withstand tuggers without damage to the wiring itself.
Except where otherwise shown in Contract Documents, use separate conduits for following
circuits:
■Microphone-level (below –30 dBu, 20 Hz to 20kHz)
■Line-level (–30 dBu to +24 dBu, 20 Hz to 20 kHz)
■Loudspeaker (greater than +24 dBu, 20 Hz to 20 kHz)
■Control (switching or synchronous, DC from 0 to 50 volts, AC from 0 to 48 volts)
■AC power (greater than 48 volts, 60 Hz)
CAUTION: Microphone and line level conduit should not run parallel to AC power
conduits within 36”if possible.

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. Protect the conductors from shorting against any other
conductor by using heat shrink or Teflon tubing on the
ground conductor.
6. Apply heat shrink at the point that the exterior jacket exposes the individual conductors.
Microphone Cabling
When connecting the signal conductors of the microphone cable to the XLR connector for
connection to the Constellation microphones:
1. Connect the shield to pin one at both ends of the cable. Do not “lift”the ground conductor
at one end. Do not attach ground connector to the chassis of the XLR connector. When
stripping the outer insulation, make sure to not damage the insulation of individual conductors.
2. Completely remove any exposed foil shield.
3. Protect the conductors from shorting against any other conductor by using Teflon tubing on
the ground conductor. Apply heat shrink at the point that the exterior jacket exposes the
individual conductors. Do not strip more insulation away from the individual conductors than
is necessary to have maximum contact with the solder cup of the XLR connector.
4. Pre-tin all three solder cups of the XLR connector and the wire conductors before making
the solder connection between the two. Do not overheat the wire conductors, as this may
cause melting of the insulation.
