P-SBOX Booth
P-SBOX15 Silencer Box Family for Boothless Cinemas
CinemaNext's P-SBOX15 family is a range of acoustic silencer enclosures designed specifically for boothless cinema installations, where digital cinema projectors are mounted inside the auditorium rather than in a separate projection booth. This second generation of lighter, more compact active enclosures protects digital projectors, reduces projector noise to inaudible levels, and keeps equipment cool, all without requiring a dedicated projection room.
What Is the P-SBOX15 and How Does It Work?
The P-SBOX15 is an acoustic hushbox that houses a digital cinema projector directly within the auditorium space. As modern cinema design increasingly moves away from traditional projection booths towards boothless layouts, the P-SBOX15 solves the central challenge of in-auditorium projection: projector noise. The enclosure acoustically isolates the projector from the audience, reducing total running noise to less than 40 dBA, whilst its built-in cooling system maintains safe operating temperatures without any extractor fan or exhaust duct.
Beyond the projector itself, the P-SBOX15 can accommodate additional digital cinema equipment inside the enclosure, including passive 3D systems, routers, and converters, consolidating auditorium-mounted technology within a single protected, sound-insulated housing.
Three Models for a Wide Range of DCI Projectors
The P-SBOX15 family comprises three models sized to accommodate different digital cinema projectors from Barco, NEC, Christie, and Panasonic.
The P-SBOX15 LOWER is the most compact model, weighing 93 kg with dimensions of 1350 x 1020 x 700 mm. It accommodates NEC NC1201/02L and 1402L, Barco DP2K-8/10S and 8/10SLP, and Christie CP23/24XXRGB projectors.
The standard P-SBOX15 weighs 98 kg with dimensions of 1354 x 1020 x 850 mm. It houses a broader range including NEC NC900/1000C, NC1201/02L and NC1402L; Barco DP2K-6E, 8/10S, 12/15/20C, 8/10SLP, SP2KXX and SP4K-12/15/20/25C; Christie Solaria One+, CP2210/15, CP23/24XX RGB, CP23XX RGBe and 43/44-15/20/25 RGB, CP24xxRBe; and Panasonic PTT-DZ series, PT-RQ and PT-RZ.
The P-SBOX15XL is the largest model, weighing 170 kg with dimensions of 1639 x 997 x 1062 mm. It accommodates the largest projectors including NEC NC18/20/24XXML, NC2041L and NC3541L, plus Christie CP43/44-15/20/25RGB.
Key Features and Benefits
The P-SBOX15 protects digital projectors installed inside the auditorium from dust and environmental factors whilst delivering the acoustic performance essential for boothless operation. Sound-absorbing and insulating acoustic cladding lines all sides of the enclosure to isolate the projector from the auditorium, complemented by acoustic silencers designed for all air inlets and outlets and dedicated sound suppressors for both incoming and outgoing air. Total noise with a running projector measures below 40 dB at 2 metres.
The built-in internal cooling system eliminates the need for an extraction duct, simplifying installation whilst maintaining safe projector operating temperatures. Easily removable side panels provide straightforward access for projector maintenance, and the enclosure includes 20A single-phase power shielding with a double 220V power socket to protect the digital projector and any other equipment housed internally.
Constructed from steel and aluminium, the P-SBOX15 features a matt black electrostatic paint finish that avoids glare in the darkened auditorium. Every unit includes the P-SBOXWATCHER card, which monitors and records temperature, humidity, and fan operation via Ethernet, supporting the remote monitoring capabilities essential for modern cinema management.
Motorised Lift Options
CinemaNext offers two motorised lift options for installing the P-SBOX15 in boothless auditoriums. The P-LIFTBOX suspends the P-SBOX15 from the ceiling, whilst the P-WALLLIFT mounts the enclosure on the back wall of the auditorium. Four top eyebolts allow the enclosure to be hung, and both lift systems provide access for installation and maintenance without the ladders or elevated platforms traditionally required for auditorium-mounted equipment.
P-SBOX15: Frequently Asked Questions
What is the P-SBOX15 used for?
The P-SBOX15 is an acoustic silencer enclosure that houses a digital cinema projector inside the auditorium for boothless cinema installations. It reduces projector noise to less than 40 dBA, protects the projector, and provides built-in cooling without an exhaust duct, enabling cinemas to operate without a traditional projection booth. The enclosure can also house additional equipment such as passive 3D systems, routers, and converters.
How quiet is the P-SBOX15?
The P-SBOX15 reduces total running noise to less than 40 dBA, measured at less than 40 dB at 2 metres with a running projector. This is achieved through sound-absorbing acoustic cladding on all sides, acoustic silencers on all air inlets and outlets, and dedicated sound suppressors for incoming and outgoing air, making the projector effectively inaudible to the audience within the auditorium.
Does the P-SBOX15 need an exhaust duct or extractor fan?
No. The P-SBOX15 features a built-in internal cooling system that keeps the projector cool without requiring any extractor fan or exhaust duct. This simplifies installation and reduces the infrastructure needed for boothless cinema designs.
Which projectors fit in the P-SBOX15?
The P-SBOX15 family comprises three models accommodating a wide range of DCI projectors. The P-SBOX15 LOWER and standard P-SBOX15 fit projectors from NEC, Barco, Christie, and Panasonic, including Barco DP2K and SP series, NEC NC900 through NC1402L, Christie Solaria and CP series, and Panasonic PTT-DZ, PT-RQ and PT-RZ models. The larger P-SBOX15XL accommodates high-output projectors including NEC NC18/20/24XXML, NC2041L, NC3541L, and Christie CP43/44-15/20/25RGB. CinemaNext can advise on the correct model for your specific projector.
What is the difference between the three P-SBOX15 models?
The three models differ in size and projector compatibility. The P-SBOX15 LOWER (93 kg, 1350 x 1020 x 700 mm) is the most compact, suited to smaller projectors. The standard P-SBOX15 (98 kg, 1354 x 1020 x 850 mm) accommodates the widest range of mid-size DCI projectors. The P-SBOX15XL (170 kg, 1639 x 997 x 1062 mm) is the largest, designed for high-output projectors used in large auditoriums and premium formats.
How is the P-SBOX15 installed in a boothless cinema?
The P-SBOX15 installs inside the auditorium using one of two CinemaNext motorised lift options: the P-LIFTBOX suspends the enclosure from the ceiling, whilst the P-WALLLIFT mounts it on the auditorium's back wall. Four top eyebolts enable the enclosure to be hung, and the motorised lifts provide safe access for installation and maintenance without ladders or platforms.
Can the P-SBOX15 house equipment other than the projector?
Yes. The P-SBOX15 has space to accommodate additional digital cinema equipment alongside the projector, including passive 3D systems, routers, and converters. It also provides a double 220V power socket and 20A single-phase power shielding to protect the projector and any internally housed equipment. CinemaNext recommends checking compatibility between specific projectors and 3D systems.
How does the P-SBOX15 support remote monitoring?
Every P-SBOX15 includes the P-SBOXWATCHER card, which monitors and records temperature, humidity, and fan operation via Ethernet. This enables cinema operators to track the enclosure's internal conditions remotely, supporting preventative maintenance and integrating with modern cinema management workflows.
