Various Crown CTs units power the setup
in relation to the RLP (Reference Listening Point), which is two-thirds of the way down the room and mid-way between the side walls, and speakers must be calibrated to obtain 85dB at the RLP. Once the design has been
approved, all the data is passed on to a spreadsheet, and after this has also been approved, the installer proceeds with installation according to these documents. Stefani continues: “When
everything is in place and tested, the consultant checks that the installation has been carried out correctly, runs a test and carries out a final calibration, using eight microphones appropriately positioned in the room, phonometer, spectrum analyser, etc. Dolby Atmos’ auto-EQ software then sends a sweep to each channel, which is recorded by the microphones, and the file created with the necessary EQ is uploaded on to the Dolby CP850 cinema processor.”
The other three rooms in the Hollywood (all operating with Dolby 7.1 surround), feature an impressive hardware total of 24 JBL 8320 three-way surround enclosures, 22 JBL 8340A two-way THX surround speakers, six JBL 3731 (5641 + 3732-M/HF) three-way screen arrays, three JBL 3732 (3739 + 3732-M/HF) three- way screen arrays, two JBL
4645C 18in subwoofers and a JBL 4642A behind-screen subwoofer. Power is courtesy of Crown DSi series amps (15 DSi 2000, two DSi 1000 and a DSi 4000).
ATMOS ELSEWHERE As well as the Gela venue, there are currently three Atmos theatres in Mestre (Venice) and another at Rome’s Casa del Cinema, which has been renamed the Dolby Room. In Rome, there’s also a private Atmos viewing theatre owned by Warner Brothers. An Atmos theatre can be used to project films with any type of audio (7.1, 5,1, stereo, etc), as the Dolby processor automatically adapts the system configuration according to audio content. The projector in the
Hollywood Multicinema is a Christie CP4230 HFR (High Frame Rate), one of the latest additions to the manufacturer’s Solaria digital units and the world’s first Superior 4K DLP cinema projector. The other three rooms also have Christie HFR projectors (two 2K CP2210 and a 2K CP2220). High frame rate movies record and play visuals at twice the rate or more of what’s shown in today’s cinemas. Increasing the frame rate stops the blurring, flickering and stuttering visuals that are common with 24fps movies. The Christie projectors
were installed by Francesco

SX-200AR digital cinema server
Giambanco and Emiliano Brunello, Ehome’s Christie system technical specialist, who was responsible for the fine-tuning of the projection systems and the GDC SX-200AR digital cinema server installed in each of the four theatres, as well as the final tests. Hong Kong-headquartered GDC Technology is the world’s second-largest digital cinema solutions provider and its SX-2000AR server supports SD, HD, 2K and 4K resolution. Leading Technologies
project manager and sound engineer, Alessandro Gianelli, who assisted with the sound design, concludes: “As well as ensuring the city a leading-edge venue offering important leisure and cultural facilities, the new cinema has made an important contribution to upgrading the area. An additional adjacent building was also built to host Studios 5 and 6 in the near future. The new Atmos system debuted on screenings of The Hobbit and Gravity and reaction from customers and impact at the box office have been extremely encouraging.”
