Opened in October 2016, Dai Nam Racecourse was created to boost tourism in the
Dai Nam tourism park complex, 24.8 miles (40 kilometres) away from Ho Chi Minh
City. With such a huge space, it was critical that audio coverage was even and clear
throughout the Racecourse. Local systems integrator and HARMAN distributor, Ba
Sao Investment, took on the responsibility of installing the audio system for Dai
Nam.
Spanning more than 460,180 square feet (42,753 square meters), the $100 million
complex was built to accommodate five racing disciplines, with tracks for dog and
horse racing, auto and motorboat racing, go-kart racing and fly-board
performances. The large racecourse is able to accommodate up to 60,000
spectators with four grandstands that seats 18,000.
The biggest challenge that Ba Sao Investments faced was the tight schedule as the
owners wanted to open the Race Course by 2017. Featuring a full HARMAN based
system with the BSS BLU Link enabled the seamless ease of connectivity, thus
helping the system integrator meet the deadline.
The completed racecourse boasts an impressive lineup of technology, with 52 JBL
AWC82 taking responsibility for main audio coverage within the stadium. Two JBL
PRX710 speakers were installed for monitoring purposes, within the control room.
Four AWC129 units were placed for coverage at the entrance of the racecourse and
parking area. Driving the speakers are 15 units of Crown CTs2000 and one CTs3000.
Both the AWC82 and AWC129 are highly weather-resistant speakers that offer 1200
x 1200 dispersion and 900 x 900 dispersion respectively. Both speakers offer
extraordinary clarity for speech, with extended frequency response for music, which
is exactly what the Racecourse required.
A Soundcraft Si Expression 1 console handles mixing duties, with its massive mix
capacity of 66 inputs, in a small format. One distinctive advantage with the Si
Expression 1 console is the FaderGlowTM that gives the user an additional level of
status indication that helps to reduce operating errors. Several different functions
can be assigned to a fader and to ease operations the FaderGlowTM indicates the
actual function type that is currently assigned to the particular fader.
BSS networked audio played an important role at the installation. A mix of five
units of BLU-50, one unit of BLU-100, one unit of BLU-102 and six units of BLU-DAN
integrate the digital signal processing into one seamlessly working audio system.
Speech reinforcement is offered via five units of AKG WMS470 Vocal Set D5. The
set includes a HT470 handheld transmitter featuring a dynamic D5 capsule for well-
balanced, powerful sound. The space diversity receiver offers both a microphone
level and a line level output.
The AKG wireless system is also supported by two units of AKG CGN521 STS, which
is a professional tabletop microphone set with excellent shock absorbing properties.
Its features a CGN521 condenser gooseneck microphone with a cardioid polar
pattern on a slim, 50 cm long gooseneck. The microphones are used for
commentary purposes.
