Marcus Theatres Chooses
Digital B-Chain™ For
UltraScreen

J
BL Professional and Crown International prod-
ucts were used in the installation of a Digital
B-Chain™ (DBC™) system at the Marcus
Theatres Elgin Fox UltraScreen, a gigantic three-
story tall screen which is a part of the new
Marcus Elgin Fox Theatre in Elgin, Illinois. The
75-foot wide UltraScreen, the largest in the
Midwest, features a state-of-the-art sound sys-
tem comprised of the Crown

Digital B-Chain and
JBL’s Academy Award

winning ScreenArray

cinema systems. The screen opened on February
25, 2004.
In a DBC system, analog or digital audio is
received from the cinema processor and is then
transported on a digital audio and control net-
work where it remains in the digital domain to the
amplifiers. In the Elgin system, analog audio is
sent to nine Crown CTs Series amplifiers with IQ-
PIP-USP3/CN modules, which power the
ScreenArray screen channels, subs, and sur-
round channels. Both the digital audio and con-
trol information is transported on a single net-
work connection.
DBC systems include the capability of system-
wide diagnostics. Automated error reporting
allows technicians and users to learn about
potential system errors before they happen and
alerts technicians immediately of any problems,
providing specific data on where to locate the
problem. The entire audio system can be con-
trolled and monitored on the same facility net-
work as concessions management, box office
ticketing, HVAC, etc, lowering infrastructure
costs.
