Kairos Multijaya designs A/V for SPH Kemang

INDONESIA: Kairos Multijaya was recently appointed to design and install a new A/V system into the Sekolah Pelita Harapan (SPH) International school. Located in the affluent neighbourhood of Kemang in south Jakarta, the students of this Christian school are now exposed to the latest A/V systems whether they are in class, in the assembly theatre or on the basketball court.

An increasing number of Chinese, Japanese and Korean multinational corporations have been flocking to Indonesia for many years, taking advantage of the raw materials and attractive costs, whilst bypassing import duties. In doing so, many managers and leading workers from these companies have established homes in the archipelago, which has led to a rise in the building of ex-patriot schools. The SPH International school is a good example of this trend, with five campuses in Indonesia.

As part of their curriculum, year 11-12 music students are required to compose and record compositions on two workstations. In addition to creating and editing, the Sibelius 7 platform syncs with Pro Tools via Re-Wire, allowing the students to play back their scores, whilst a vast sound library provides access to a wide range of instruments. A Mackie HD1521 speaker system mixed on a Yamaha 01V console has also been set up for musical performances.

Located on the same level is a 200-seat theatre, which is used for drama and musical performances in addition to rehearsals. The 8m ceiling height was reduced to 5m owing to the presence of a fire hydrant pipe.

Designer Leo Tanzil opted for changing colour LEDs to be inserted into this newly created translucent stretch ceiling in order to create a spacious ambience. Meanwhile, the ceiling acoustics have been mitigated by the natural teak wood flooring and walls, together with a rear fabric wall discretely hiding a cellulose membrane.

‘With the teak, it’s a very natural sounding theatre, so it doesn’t need much sound reinforcement,’ explained Mr Tanzil. ‘The wood provides natural and consistent reverberation throughout, but a little absorption for the rear wall was needed. You have to be careful knowing that children need the room to support them and give them the confidence to sing.’

Following EASE 4.3 simulations, L-R self-powered Meyer Sound UPA-1P speakers were installed and augmented by 500 HP subwoofers built into the stage below. ‘These speakers sound very natural in such an environment,’ furthered Mr Tanzil. RCF TT+25 SMA monitors are used as the fold-back system in addition to stand-alone speakers when required.

A FOH Allen & Heath iLive R72 digital console is connected to all the Beta 58 microphone inputs including two Shure SLX 4 wireless channels on stage via an iDR32 Mix rack. A Madi link to the classroom studio further enables students to mix live productions taking place in the theatre. An XTA DP424 processor provides further speaker management. Video control is provided by an Edirol 4-channel V4 video mixer taking its feed from a PC, HD video recorder and a camera. The resultant signals are fed through a Kramer VP-501 UXGA scan converter and Extron V/A distribution amplifier before being displayed onto a central 4x3 motorised screen in addition to L-R 150-inch Grand View screens via three Eiki projectors.

The gymnasium hosts basketball, table tennis, badminton and volleyball. The upper balcony levels are spectator galleries, where commentaries are provided via EAW CIS400 ceiling speakers, whilst larger format CIS991 speakers were required above the playing area itself owing to the higher ceiling height. Both ceiling speaker systems are powered by dual Lab.gruppen C28:4 amplifiers.

However, the gymnasium is often used for special events, such as concert performances. A stage can be quickly erected, which is served by fly-bars and trussing above for lighting and drapes. Two VMB towers can then be put into place, which host a six-per side self-powered RCF TT+31 line array system boosted by four TTS28 subwoofers.

Six RCF ART725 and four TT+25 SMA loudspeakers are deployed as monitors or as stand-alone systems, whilst Shure SLX wireless systems are used for speeches and commentaries. An Allen & Heath iLive T-112 console is used as a FOH console and is linked to the stage via an iDR8X Mix Rack. A single 8.0m x 4.0m central screen receives its Dataton edge blended images via two motorised Eiki 5000 lumens projectors. Two smaller L-R motorised screens are served by rear mounted Eiki LC-XL-200 projectors, which have been housed in sturdy wooden cabinets to protect them from the ball games below.

Whilst SPH Kemang practises an internationally certified curriculum based upon the International Baccalaureate (IBO) and Cambridge programmes, Mr Tanzil and his colleagues attend the Infocomm CTS certification course.
