1 Design Introduction This design for your home theatre / media room has been carefully considered and a huge amount of care has gone into the design process and equipment selection. There are clear performance objectives for both audio and video and those are set out and mentioned throughout this document. Home theatre design is not a subjective engineering process, it has been clearly defined by many standards documents and trade organisation codes of practice. This theatre design is based on CEA/CEDIA CEB-22 & CEB-23 Home Theatre standards for design as well as several ITU documents on audio and video criteria. The use of Dolby Atmos, DTSX and Auro 3D configuration design guides have also been used to create a technically accurate room but like all rooms some design compromises must be made. All home cinema designs require a careful mix of science & art. Every room has issues that need to be dealt with at the design stage and the best rooms are always those that have had the best application of intelligent compromises applied. We have followed all known standards and codes of practice in the creation of this design and as such have guaranteed a certain amount of predictability in the systems performance. We are often requested to create several designs of the same room, with different equipment, configuration and performance objectives before finalising on one design. This is not unusual and it is this process that really adds value to the professional home theatre designer and installer. Below you will not only see a full specification and bill of materials of loudspeakers, amplification, processing and projection systems amongst other things; but solid engineering reasons for why certain pieces of equipment have been selected. Performance objectives have been set out to 105db reference level at the listening position for the audio systemas well as a minimum of 30 ftl for the front projection system in relation to the video image.it is also important to mention that the noise floor of the room itself is important to increase the perception of the dynamic range of the audio. The video also requires careful control of both natural and artificial light to increase the perception dynamic range of the video image. Cinemas and media rooms also need to be well ventilated and comfortable places to spend your time as well as the requirement for a simple control interface that will allow you to enjoy the movie or game with the minimum of fuss.

2 Room and Project Design Codec and configuration is Dolby Atmos Reference Job Design Date 21st October 2017 Room Design Considerations Room design and structural properties must be carefully considered. The challenge is to create an environment that is not only comfortable but that enhances the audio and video from a performance standpoint. For sound, the room itself is very important. The room is more in control of sound at the lower frequencies, however, as the frequencies rise then so the loudspeakers take back more control from the room. This is never truer than with high quality loudspeakers and a good processor. The room should be treated acoustically with fabrics and materials that will enhance the selected electronics. For instance it may be required that we install some absorption, diffusion and maybe some reflective materials to create an interior that will enhance the system design set out in this document. It is also recommended that post-installation calibration be carried out on both the audio and video system to truly gain the full potential from the electronics and loudspeakers that have been specified in this design. HAA, ISF and THX calibrations are recommended on both the audio and video systems to finely tune the system to its most optimum potential.

9 Audio Design - Our Approach This object of this audio design is to ensure that the sound reproduction within your home cinema room/media room is faithful to the technical production of the movie (or music, show or game), to provide you with an immersive audio experience. This design is embedded with the correct engineering principles to ensure that your home cinema system delivers correct measurable audio performance. The CEA/CEDIA guidelines accept that, whilst the objective is to simply adhere to movie technical production standards, in most installations, intelligent compromises will be needed to balance this aim with the physical, aesthetic and budgetary parameters of each installation. To ensure accurate sound reproduction, the following performance objectives have been considered and embedded within the calculated design No Colouration. The sound should not be coloured and sound from each loudspeaker should be tonally similar. Continuous Sound Stage. Continuous sound in the front sound stage, from the left speaker, through the centre and to the right. No bias to either side. Envelopment. The sound reproductions should give the user the sense of envelopment and immersion in non-directional sounds, except where sounds are deliberately directed to a particular channel/loudspeaker for a specific effect. Focus. The part of the loudspeaker alignment process that means the listener remains in the in direct focus of the loudspeakers horizontal and vertical dispersion characteristics. Dialogue Intelligibility. Dialogue intelligibility should not be degraded. No Perceptible Distortion. The audio should not be distorted when played loudly. Consistent Performance. The prime listening position will receive the best performance, but audio performance should be as consistent as possible over the whole seating area. Low Frequency Accuracy. The system should support the full frequency range consistently across all seats. Low frequency performance should should not sound distorted or boomy. No Background Noise. Background noise should be as low as possible (inaudible) to be unobtrusive. Isolation. The cinema should not be affected by noises outside of the room and, conversely, the sounds made inside the cinema should not be disruptive to normal activities outside of the space. Further activities within the implementation of the design, such as the installation, commissioning and calibration, will permit these criteria to be fully considered and achieved. Page 9 of 30

19 Video Design - Our Approach This video design has been produced to ensure that the visual reproduction within your home cinema/media room is faithful to the technical production of the movie (or music, show or game). CEA/CEDIA guidelines accept that, whilst the objective is to simply adhere to movie technical production standards, in most installations, intelligent compromises will be needed to balance this aim with the physical, aesthetic and budgetary parameters of each installation. To ensure accurate video reproduction, the following criteria have been considered and embedded within the calculated design Dynamic Range (contrast ratio). The ratio between the maximum and minimum measurable light intensities (black and white) that are created by the video system. Colourimetry. The measurement of colour and colour appearance and the prediction of perceptual matches on the basis of physical measurements. Gamut. The subset of colours which can be accurately represented. Resolution. The number of distinct pixels in each dimension that can be displayed. In embedding these considerations within the video design, we have ensured that the characteristics of the display device are inherently matched to the related video components. This will provide an accurate and measurable video performance. Further activities within the implementation of the design, such as the installation, commissioning and calibration, will permit these criteria to be fully considered and achieved. Page 19 of 30

20 Video Considerations Manufacturers claimed figures video projectors are used as a guide only. As a rule of thumb, lamp based projectors / light engines will slowly deteriorate over time and usage. They will also initially appear "less bright" after a professional calibration. The requirement to hit 30ftL is a good starting point & nice bright image. After calibration and lamp degradation it is recommended that the initial figure is halved and for proposed 3D view, it should be halved again. These are just guidelines but ones we follow to make sure that the correct projection system as well as screen gain are selected from the outset. Video Requirements Screen Fixed screen vertical position is with screen C/L at the listening position of 1.2m (47.5") from floor level. 2,794mm W x 1,570mm H (110.0" W x 61.8" H) Area = 4.39 m² (47.25 ft²) Screen Manufacturer Projecta Screens Fabric / Model HomeScreen Matte White All Aspect Ratios, 1.00, 120 Size and Aspect 110" Screen Size, 4k Gain 1.0 Acoustically Transparent Yes Page 20 of 30

21 Projecta Screens HomeScreen Matte White All Aspect Ratios HomeScreen High quality fixed frame screen with a matte black frame and a wide selection of screen surfaces. The aluminium frame for the HomeScreen has a black matte finish. The frame (8 cm wide and 3 cm deep) features a beveled edge, reducing shadowing of the image. The projection screen surface is attached to the rear of the screen with Velcro. The frame and projection screen surface can be custom made to project requirements. The projection surface is exceptionally flat, making it suitable for all types of data and video projection. The frame is easy to mount with the supplied mounting brackets. Page 21 of 30

Be totally immersed in the world that is portrayed, as images envelop you. Beyond 2K is a new world of moving experiences that only 4K can deliver. JVC's e-shift 4 technology is able to reproduce the finest nuances and unique tone of every visual work, enabling you to enjoy a 4K-resolution* image with extreme realism and presence in your home theatre environment. * 3840 x 2160 [4K e-shift 4 (not native 4K)] Original 4K e-shift Technology continues to evolve JVC s e-shift technology shifts sub-frames by 0.5 pixels both vertically and horizontally to achieve 4 times the pixel density of the original content. The latest e-shift 4 Technology is capable of inputting full-spec 4K video signals including 4K60P 444 thanks to the optimised engine and the newly adopted high power lamp. These improvements result in an even higher definition picture with more precision. New Multiple Pixel Control JVC s original high-performance image processing technology, Multiple Pixel Control, has been improved to match the trend towards higher resolution. Through adoption of a Page 22 of 30

23 new analysis algorithm, the MPC is now capable of more accurate diagonal detection between frames for both full HD and full 4K resolution signals, delivering a thoroughly immersive high-definition 4K image. Clear Motion Drive with High-speed LSI Further improvement has been applied to JVC s original Clear Motion Drive. It now is compatible with 4K60P 444 signals for reproducing moving images without ghosting or afterimage issues. New Motion Enhance In addition to the improved Clear Motion Drive, the new D-ILA projectors are equipped with originally developed Motion Enhance technology. By optimally controlling the driving performance of D-ILA devices by image characteristics, residual images and blurring that are often found in fast-moving images are reduced. JVC s original Clear Motion Drive and Motion Enhance technologies will help to reproduce a variety of crisp and smooth moving images. JVC Developed Proprietary D-ILA Device The exceptional picture quality of JVC projectors is achieved by the precision technology behind the company's original D-ILA devices. The latest device, which has an even narrower gap between pixels and is planarised, achieves brighter images rich with contrast. The device is optimally designed to complement ultra-high 4K resolution for precision image expression with virtually no screen-door effect. Page 23 of 30

24 Reverberation and Acoustic Treatment Interior acoustical treatments provide for the optimal reproduction of music and movies in stereo and multi-channel formats, as well as for relaxed conversation. Their usage is guided by two parallel requirements reverberation time (RT60), and enhancement of sounds delivered by the loudspeakers; simply not to detract from the delivery of sound by these chosen loudspeakers while also achieving reverberation time objectives. We aim to design cinema rooms based around a RT time varying between 0.2 and 0.5 seconds, specifically working towards the sweet-spot of 0.39 for rooms with standard 5.1 and 7.1 configurations, and 0.32 for rooms where immersive audio layouts are implemented. We can in this way guarantee that immersion, dialog intelligibility and voice quality are of the best achievable for that room. Page 24 of 30

25 Reverberation and Acoustic Treatment The table on the following page shows the selected acoustic treatments with the Sabine calculations for reverberation time (RT60) at 500Hz and other frequencies. Page 25 of 30
