Control Logic Systems Integrates PA System at Jurong Point 1

SINGAPORE: The Jurong Point shopping
mall located in the west of Singapore is a
huge shopping mall that has a newer annex

aached to the older mall (Jurong Point 1).
The newer annex (Jurong Point 2) has been
in operaon for a few years now. Retails
shops, Knowledge Enrichment facilies, a
supermarket, a cinema, banks and a large
range of F&B outlets enjoy brisk business at
the malls. The mall management felt that
the old PA system at Jurong Point 1 needed
an update and approached Control Logic
Systems, for a soluon that would meet
their needs.

“We looked at their requirements and what
was in place and suggested a full digital

system to be installed,” said David Seow of
Control Logic Systems Pte Ltd.

The heart of the system features one unit of
RCF MU 5100 8 IN/24 OUT Digital Matrix

complemented with three units of RCF MT

5078 8 Channels Automac Amplifiers

Changeover and Speakers Line Surveillance

modules. Also installed at the control room

was one unit of RCF MS 1033

CD/Tuner/USB Player and two sets of RCF

BM 5804 Master Paging Console + 3 x BM

5808 8 Zones Selecon Module.

“We also installed Class D power amplifiers

from RCF. These comprises of four units of

UP 8501 500W Single Channel Class D

power amplifier, 10 units of UP8502 2 x

250W Dual channel Class D amplifiers and

two units of UP 8504 4 x 125W 4 Channel

Class D power amplifiers. All without

transformers.

The Class D amplifiers offer power

efficiency and that is important for mall

operaons. The amplifiers drive the 187

units of Merlaud FP 1512 6W ceiling

speakers, 39 units of CLS full range box

speakers that have been installed at

staircases and 18 units of Cornered Audio

ViV4 full range speakers that have been

installed at level 3 of Jurong Point 1.

The Cornered Audio ViV4 speakers were

specially chosen as they needed to not

only blend into the design but be powerful

enough to ensure any crical

announcements are heard. Level 3 is at the

top level with a high ceiling. It also has a

food court which means there are also

exhaust fans in operaon that generally

feature 98db SPL. "The Cornered Audio

speakers offer 105db SPL. However, the

current situaon is that the number of CiV4

is not enough and may require another 11

units because the ambient noise is too high

and the mounng height is another problem

for the desired SPL to be reached at the

listening height," said David.

Altogether the PA system has been divided

into 24 zones. David highlights that the RCF

soluons especially the power amplifiers

have also saved the mall rack space in the

control room as they take up less space

compared to the old system.

Vincent Lim, head of security at Jurong Point

1, comments, “The new system installed is

straight forward and user-friendly. It is easy

for us to operate as it offers flexibility be it

in operang background music or needing

to do announcements or emergency

operaons. We do not need to fiddle

around with sengs. If we use the paging

system, it automacally over-rides all the

other audio. Of course the support from

Control Logic Systems has been great with

all the workings of the systems clearly

explained to us.”

David highlights, “The Matrix has a back-up

microphone and the UPS offers four hours

of back-up should there be any electrical

outage.”

The mall management and especially the

security officers are pleased with the new

digital soluon that has enabled them to be

more producve and effecve in doing their

job.
