Infosys employs QSC audio for Bangalore convention centre

In addition to live performances, the 1,400 seater auditorium also had to be able to playback movies on a giant screen in both the latest 2K digital format as well as in regular 35mm, with 7.1 digital sound.

MRH Digital Systems were among the companies who responded to the brief, and installed QSC Audio SR and networking products as part of an entire multimedia integration. QSC’s flown ILA line array system, driven by PowerLight amps, were installed to handle a range of concerts — from Indian classical to hard rock — and theatre events where speech intelligibility was vital.
Two sets of amplifiers were required — one for the FOH speakers and one for the delay system to the balcony.  Instead of traditional balanced wiring between the two racks MRHl opted for a CobraNet system.

QSContol.net was provided for room EQ via a wireless network, allowing the in-house or visiting sound engineers to walk around the venue with control over the complete system.  In addition, the installers provided a selection of NAC-100 local controllers, installed on the network to allow presets, room modes etc to be flipped through. 

Finally, for constant system monitoring MRH also installed a fixed computer on the network, using QSCreator to develop an error reporting GUI — enabling levels, faults, amp temp, loads, etc to be close-monitored.

For the FOH PA system, two hangs of the 8 x WL2082-I are complemented by 4 x WL115-sw subwoofers flown behind.  For additional bass reinforcement 2 x WL218-sw enclosures have been flown in the centre, while up at balcony level MRH Digital have deployed a further two hangs of 4 x WL2082-I. 

The system is driven in 4-way configuration, with PowerLight PL325 amplification used for the highs, PL340 for the mids and lows and PL380 for the subs.

Processing and monitoring for the complete system takes place in the two QSC Basis devices, and via QSControl.Net.  Completing the PA configuration are powered HPR 122i’s, which are used as floor monitors.
