Installation guide

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.
