THE EXPERTS BEHIND THE SOUND
When you walk into an IMAX theater, it is clear that you are in for anuncommon cinematic experience. The steep rake of the seating and the hugedomed screen-typically 100-feet wide and 60 to 70-feet high-promise animmersive, "middle-of-the-action" feel for films such as MacGillivrayFreeman's 1998 film Everest. But what you don't see is the audio systemdesigned to deliver a sound stage big enough to complement the huge picture.
Birmingham, Alabama-based Sonics Associates, a subsidiary of Toronto's IMAXCorporation that designs and builds sound systems for IMAX theaters,creates the sonic canvas. "The director and sound designer should be ableto choose the ambiance they want to create without the room or our systeminterfering," says Lynn McCroskey, president and CEO.
Achieving this goal starts with close attention to the physical layout andacoustics of the theaters. "IMAX theaters must meet a NC-25 Noise Criteriarating," McCroskey says, "compared to NC-35 in typical theaters wherebackground noise from air conditioning or traffic might be 10dB higher. Wealso require 0.8-second mid-band reverberation time, which is very lowconsidering the cubic volume of our theaters."
The Sonics playback systems use six discrete channels: left, center, right,left rear, right rear, and top center. "Material below 80Hz from each ofthese channels is rolled out of the main speakers and summed into oursub-bass system," explains McCroskey. The company's latest formatspecification also allows for a discrete low-frequency channel, effectivelymaking it a "6.1" channel system. But McCroskey says, "Most IMAX producersare not yet working in that format."
The playback system differs in several respects from surround systems inconventional theaters. Perhaps the most unusual element is the top-centerspeaker. "The typical IMAX screen," McCroskey explains, "is close to aconventional 4:3 aspect ratio, but much, much bigger. So you have a greatdeal of vertical, which gives you the opportunity to do a 'voice-of-God'loudspeaker." Another difference is the use of point-source surround, asopposed to the multiple small surround speakers used in conventionaltheaters. "Conventional rooms," McCroskey says, "come in so many differentshapes that it is nearly impossible for them to make point-source surroundwork."
Overall IMAX system power varies depending on the size of the room, but itis typically in the range of 12,500 watts. "The power is not there for theloudness," McCroskey says. "It's there for clarity and freedom fromdistortion." The enclosures are three-way systems using componentscustom-designed and manufactured to Sonics' specifications. Sonics combinesfour low-frequency loudspeakers in each cabinet with nested high- andmid-frequency horns. McCroskey points out the trapezoidal dispersionpattern (narrower at the top than the bottom), designed to match thedistinctive shape of IMAX theaters.
Using a sub-bass system for the deepest lows, McCroskey says, minimizesphase coherence problems. "In most installations, we use eight sub-bassloudspeakers, each in a 16-cubic-foot enclosure," he says. "The enclosuresinclude a filtering labyrinth we designed that physically traps thehigher-frequency components that can otherwise cause overtones anddistortion."
Another distinction between IMAX and other theater surround systems is thatSonics uses no digital audio data compression. Both the DDP and DTAC linesare full fidelity, "double-system" approaches, meaning that the sound isnot recorded on the film itself. "DDP uses three CD-Audio discs with apatented sample-accurate playback synchronization system," McCroskey says.DTAC, the company's newest system, plays back audio files either fromDVD-ROM or from a built-in hard disk. In some older IMAX theaters, theoriginal 35mm six-track, full-coat mag-sound system used from 1971 through1988 is still in place.
"These days most soundtracks are produced in digital formats," McCroskeysays. "They are usually sent in on TASCAM DA-88, and we transfer towhatever format is needed for the theaters where the film will play. OnEverest, for instance, we created both DDP and DTAC discs."
The Everest ExperienceWhen it came time to mix Everest, the tightly controlled audioimplementation in IMAX theaters offered mixers a reliable platform to aimfor. But how does the environment affect the actual finished mix?
Ken Teaney, chief re-recording mixer for Los Angeles-based EFX Systems andWilshire Stages, mixed Everest with colleague Marshall Garlington. Heexplains: "One of the things I exploit heavily compared to 35mm is thatIMAX surrounds are full-frequency speakers-big with a lot of low end. Thatmakes it easier to use interesting panning and changes of perspective tosupport the sense of motion you get from that large picture.
"In Everest, for example, sound comes from all around you in the interiorhelicopter shots, but when you cut to the copter going up the canyon, thesound is distant in the center speaker. We try to do that kind of thing for35mm films as well, but most surround speakers can't reproduce the low end,so the sound gets thinner as it moves from front to rear. With IMAX, thesound doesn't change at all, just the placement."
As in conventional mixing, Teaney focused dialog in the center. "Most IMAXpictures are driven by narration and voice-over," Teaney says. "To supportthe story, we place narration and voice-over in the center and also about10dB down in the left and right. Synch dialog, however, we keep only in thecenter."
Meanwhile, mixers kept the music out of the dialog's way. "In Everest, themusic is only in the four corner speakers," Teaney explains. "That actuallymakes it bigger spatially with a wider stereo image. Steve Wood, who workedwith Daniel May to orchestrate and mix George Harrison's compositions, usedthis format very effectively in places like the storm scene where there isa Tibetan bell that swirls around the room. It's a perfect complement towhat we did with effects to put the audience in the middle of all that windand ice."
As for effects placement, Teaney generally uses left and right instead ofthe center. "But where the action is center-screen, so are the effects, orelse the illusion is gone," he notes.
Teaney uses the top-center speaker sparingly. "There's one scene where aclimber is belaying another climber; you don't see him, but you hear himabove her," he says. "In another scene, the avalanche starts in the topspeaker and pans its way down. But that channel is really only useful in afew specific instances."
Everest was the first IMAX film where the final mix was done on location inan IMAX theater, the Irvine Spectrum. That meant the mixers did not have tomake several rounds of notes while watching the film and then implementchanges back at the EFX dub stage. But they did have to set up facilitiesin a working theater that was not available until 10 at night (after theday's last screening). They worked from a 24-track premix made at EFX withsix tracks each for effects, backgrounds, and music; three for Foley; andone each for narration, voice-overs, and dialog. EFX made a discrete premixto 24 tracks: six each for effects, backgrounds, and music; three forFoley; and one each for narration, voice-overs, and dialog.
Teaney and Garlington noticed some interesting differences between thesound on site and the sound on their dub stage. "The left and rightspeakers were so much further out," Teaney recalls, "that we decided wecould push both the background effects and the music up a bit withoutinterfering with the narration. That was great because the higherbackground levels of wind swirling around you really make it more of anexperience."
During the mix, picture was video-projected (IMAX projectors only rollforward). But at five in the morning when the mix seemed right, sound wassynched to the IMAX print for a check pass. "It was pretty exciting tofinally hear and see it all together," Teaney says. "Any fatigue we had upuntil that moment was gone the minute that big picture began to play."

XMOOR ADDS POWERFUL NEW OPTIONS TO ZON AUDIO
Company unveils new modules for enhanced remote control and paging
For Immediate Release
(Birmingham, AL - November 11, 2003) - Oxmoor Corporation today unveiled enhancements to its ZON Whole House Digital Audio System - the ZIR -232 Device Commander and the ZEP -11 External Paging Interface. Responding to many integrator and end -user requests, Oxmoor developed these modules to provide even greater flexibility and functionality to the ZON Whole House Digital Audio product line.
ZIR -232 DEVICE COMMANDER:
The ZIR -232 module, also called the Device Commander, controls nearly all of today's popular brands of consumer electronic devices. It also interfaces with most home automation systems - and all from one convenient module designed exclusively for the ZON ZR -98 Router. External devices can be controlled via IR, RS -232, or a combination of both.
The Device Commander comes with an extensive pre -programmed library of the most often -used consumer electronics IR codes. For specialty equipment, there is a simple -to -use learning feature, which will memorize most any remote's IR codes and store them in on -board non -volatile memory.
"The Device Commander really creates a flexible system for the user, " said Lynn McCroskey, president and CEO of Oxmoor. "ZON is a plug and play system that works right out of the box without programming. However, for dealers and end users that desire a custom setup to integrate ZON with home control and other entertainment products, this new device is the business."
In addition to IR control, the Device Commander features a bi -directional RS -232 port to extend control capabilities. Control commands stored in the ZIR -232 are integrated with the ZON ZAC -60 Controller/Amplifier's revolutionary user interface and in conjunction with the ZON Router's on -board RS -232 port. Icons and/or text labels are assigned to stored commands and can be selected directly from a ZAC -60 display. Custom command configuration software allows full integration with the ZON system.
ZEP -11 EXTERNAL PAGING INTERFACE:
The ZEP -11 External Paging Interface expands the capabilities of the standard ZON paging features. Telephone and security systems, intercoms - and even weather radios - are integrated into a ZON system quickly and easily.
Custom engineered for the ZON ZR -98 Router, the ZEP -11 features an auto -sensing audio input (single RCA jack). An adjustable VOX threshold setting allows you to fine tune the sensitivity of the auto -sensing input. Audio received by the ZEP -11 is automatically routed to the paging bus and processed according to the paging configuration(s) in place for the ZON system.
A dry contact closure "trigger" adds additional flexibility. When used alone, the trigger is suitable for creating a system -wide mute, allowing the system to mute on external events such as doorbells, telephone and security systems. The trigger can also be used in conjunction with the page bus input to add sound to external events.
"With the addition of the Device Commander and the External Paging Interface to the system we have taken the ease -of -use equation one step further," McCroskey added. "We also have given our dealers a superb pair of add -ons that are easy to install and that will add to their customers' satisfaction for years to come."

"The IMAX system has its roots in EXPO '67 in Montreal, Canada where multi-screen films were the hit of the fair. A small group of Canadian filmmakers/entrepreneurs (Graeme Ferguson, Roman Kroitor and Robert Kerr), who had made some of those popular films, decided to design a new system using a single, powerful projector, rather than the cumbersome multiple projectors used at that time. The result: the IMAX motion picture projection system which would revolutionize the giant-screen cinema. IMAX premiered at the Fuji Pavilion, EXPO '70 in Osaka, Japan. The first permanent IMAX projection system was installed at Ontario Place's Cinesphere in Toronto in 1971. IMAX Dome (OMNIMAX) debuted at the Reuben H. Fleet Space Theatre in San Diego, CA in 1973." (quote and picture from the IMAX page by James Neihouse)
The IMAX digital sound system was developed by Sonics Associates of Birmingham, Alabama. In 1988, Lynn McCroskey and Jim Cawhon developed a Digital Disc Playback system (DDP) that recorded 2 channels of uncompressed digital sound on an audio compact disc. This system with 3 discs and 6 channels began to replace the multitrack magnetic tape sound systems used in IMAX theaters since 1971. In 1993, Sonic introduced the IMAX 3D sound system with 10 channels for the Sony IMAX theater in New York. Theater speakers produce 8 channels from 4 CD disks synchronized with the15-perforation 70 mm filmstrip running through the projector horizontally past a 15,000-watt lamp at 48 frames per second. The 3D headset has 2 additional channels for the binaural Personal Sound Environment (PSE). "Binaural sound emanates from the headsets' two small speakers, just above and slightly in front of your ears; they cover all but the frequencies below 100 Hz. Low bass is handled by a pair of subwoofers behind the giant screen. Four full-range speakers, also behind the screen, keep sounds tied solidly to the
IMAX 3D headset from Sonics
film's images even if you turn your head; if you have trouble imaging binaurally (as some people do), these speakers will prevent front sounds from seeming to come from the sides or rear. Two more speakers, in the rear of the theater, carry only surround ambience; the headset's binaural speakers carry sounds that are supposed to originate behind you. Eight channels of an 18,000-watt, 10-channel amplification system feed the speakers; the other two channels feed the binaural signals to the headsets. These amps are fed from four audio CDs, computer-synchronized with one another and with the projectors. The headsets can receive four separate soundtracks, so a movie could be presented in different languages simultaneously if the theater provides enough channels." (quote from Ivan Berger)
Lynn McCroskey is President and CEO of Sonics Associates, a subsidiary of Toronto's IMAX Corporation. In an interview with Millimetermagazine, he explained the difference between the IMAX sound system and the surround systems in conventional theaters: "The typical IMAX screen is close to a conventional 4:3 aspect ratio, but much, much bigger. So you have a great deal of vertical, which gives you the opportunity to do a 'voice-of-God' loudspeaker." Another difference is the use of point-source surround, as opposed to the multiple small surround speakers used in conventional theaters. "Conventional rooms," McCroskey says, "come in so many different shapes that it is nearly impossible for them to make point-source surround work." Overall IMAX system power varies depending on the size of the room, but it is typically in the range of 12,500 watts. "The power is not there for the loudness," McCroskey says. "It's there for clarity and freedom from distortion." The enclosures are three-way systems using components custom-designed and manufactured to Sonics' specifications. Sonics combines four low-frequency loudspeakers in each cabinet with nested high- and mid-frequency horns. McCroskey points out the trapezoidal dispersion pattern (narrower at the top than the bottom), designed to match the distinctive shape of IMAX theaters.

"In most installations, we use eight sub-bass loudspeakers, each in a 16-cubic-foot enclosure," he says.

3D Immersive Sound (RISE3D)
Our patented audio technology creates 3D ultra-realistic immersive sound environments (RISE3D). The RISE3D technology has a very small physical footprint and can be easily incorporated into VR and Augmented Reality products. This technology has many advantages over traditional headphones or standalone speaker systems. First, nothing makes contact with the wearer's ears. Second, each wearer has their own personal environment that tracks with content being viewed. RISE3D can have custom content created in the RISE3D format producing an experience that is nothing short of amazing. In addition, it can simulate 3D for existing games or applications without any content modification, creating a far superior experience than any traditional headphones can. RISE3D technology has already enjoyed commercial success in IMAX Theaters. Sonics2 is looking for opportunities and partnerships to deploy this technology in the VR & Augmented Reality market segments.
CANTERBURY CHURCH GAINS INVISIBLE INTELLIGIBILITY WITH RENKUS-HEINZ ICONYX
In Install News by tfwmMarch 2, 2015
Established in 1950, Canterbury UMC has grown to embrace both traditional and contemporary worship styles, with separate sanctuaries for each on its Mountain Brook, Alabama campus. Recently, the church engaged Twist Technology of nearby Birmingham to address its ongoing issues with intelligibility of the spoken word in the main (traditional) sanctuary.
For Twist CEO Lynn McCroskey, there were two challenges to be overcome in this design/build project. “First, we had to create articulation in an extremely reverberant environment,” he explains. “At the same time, aesthetics was a primary concern. This is a beautiful worship space, and they did not want to see a big speaker cluster or anything like that.”
Two Iconyx IC24-R-II digitally steerable column arrays cover the entire room, delivering advanced digital beam steering to direct the sound to the seating areas, and away from the side walls, balcony facings, and other reflective surfaces. And the Iconyx slim, low-profile design enabled Twist to create a system that sounded great, with minimal visual impact.
The IC24 column is 10 feet tall, but only about six inches wide, so it’s really more like an architectural element than a loudspeaker,” says McCroskey. “It’s designed to be flush-mounted to the walls, so there is no interference with the congregation’s sightlines. With the precision color-matched paint job, they really just look like part of the building. Most people don’t even realize that there are two 10-foot tall speaker columns behind the altar. The church elders are very pleased and impressed.”
Iconyx steered beam technology enabled Twist Technology to meet Canterbury’s seemingly conflicting goals of preserving the sanctuary’s big sound while creating exceptional intelligibility. “We’ve used the Iconyx successfully in several architecturally sensitive installations,” McCroskey reports. “The directional control is a huge help with articulation, and really helps control reverberation. For a large space like this, with high, vaulted ceilings, a balcony, and hard surfaces everywhere, beam steering is the perfect solution. The pipe organ and choir music still soars, but now the spoken word can be clearly understood from every seat.”
Our team has created and produced scores of products and systems for clients across the globe. We have the capability of taking a product or system from concept all the way through production/installation and beyond.

Evans & Sutherland, Spitz and Sonics2 Join Forces to Create AEOS Theaters
September 22, 2017—Evans & Sutherland (ESCC) introduces AEOS Theaters, a groundbreaking new alliance between E&S, Spitz, and Sonics2. The companies have joined forces to create a new generation of ultra-high resolution giant screen cinema experiences for immersive domes and giant flat screen theaters.
AEOS Theaters reimagine the immersive cinema experience using ultra-high resolution digital imagery, the highest-fidelity sound, and beautifully seamless screens for an audience experience that’s just this side of reality. Using a seamlessly blended array of laser or lamp-based projectors, AEOS allows domes or flat screen theaters to achieve resolutions of 8K or even higher while maintaining their fulldome, partial dome, or 4:3 aspect ratio flat screens. An AEOS theater can also function as a multipurpose venue with available turn-key presentation and digital marketing packages. AEOS is the complete solution for giant screens.
Jon Shaw, CEO of E&S said, “As we looked at the giant screen cinema from the standpoint of the audience, it became clear the entire experience needed to be reinvented to take full advantage of today’s state-of-the-art digital technology. By combining E&S’ stunningly sharp display systems with Sonics2 high-powered surround sound audio systems, and Spitz seamless domes or flat screens, AEOS has introduced a new gold standard for giant screen theaters.”
“Since the advent of digital cinema, image resolution has been limited to what a single projector can achieve. This is not the case with AEOS. Other providers are limiting themselves to a maximum image resolution of 4K by using only one projector. This is a big downgrade in resolution from 70 mm film,” said Lynn McCroskey, CEO of Sonics2. “In addition, many companies are just providing generic off-the-shelf audio approaches which are inadequate for giant screen theaters. AEOS’ approach redefines what quality sounds like with purpose built speakers and equipment specifically created for giant screen venues. The 15/70 film experience has been the gold standard for giant screen theater image and sound quality for nearly 50 years. AEOS Theaters shatters that standard and redefines it.”
AEOS creates a truly landmark immersive experience, enabling theaters to stand out from the commercial theater down the block. This technology helps drive a fresh approach focused on giant flat screen and dome theaters. In addition to the new technological approach, AEOS focuses on audience experience and additional theater functionality, ultimately increasing community engagement and attendance.
