South Korea’s Megabox cinema unveils JBL and Crown Dolby Atmos system
SOUTH KOREA: Part of South Korea’s Megabox chain of movie theatres, the Baeksuk Megabox cinema has recently been equipped with a Dolby Atmos surround sound system featuring JBL loudspeakers and Crown amplifiers.
The system was installed into the theatre’s 275-seat M Hall. Five JBL 5672 three-way loudspeakers and five 4342A loudspeakers were deployed as the main left, centre and right channel speakers. Meanwhile, eight JBL 4642A dual-18-inch subwoofers and two PRX618S-XLF extended low-frequency 18-inch subs provide the low end.
In total, 48 JBL 8350 Cinema surround speakers are arranged throughout the theatre. The loudspeakers are powered by 16 Crown DSi 4000 and 29 DSi 2000 amplifiers, which are specifically designed for cinema applications.
‘In order for Dolby Atmos to be heard the way its designers intended, every aspect of the system has to be perfectly optimised,’ explained Hueng-Sik Jung, manager of the projection technique team at Megabox. ‘The coverage pattern of the loudspeakers has to be precisely directed and smooth throughout the theatre and the amplifiers have to be capable of delivering clean, powerful sound at high volume levels. The JBL loudspeakers and Crown amps in the Megabox cinema are ideally suited to these requirements and the sound in our theatre is so enveloping and lifelike that it literally almost seems unbelievable at first listen!’
The Dolby Atmos specification requires 105dB peak SPL at the reference point in the theatre along with numerous additional stringent technical requirements.
