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
Find answers to common questions about the P-SBOX15 enclosure.
What is the P-SBOX15 used for?
The P-SBOX15 is an acoustic silencer enclosure for digital cinema projectors in boothless installations. It reduces noise to under 40 dBA, protects the projector, and offers built-in cooling without an exhaust duct.
How quiet is the P-SBOX15?
The P-SBOX15 reduces running noise to less than 40 dBA at 2 metres, making the projector effectively inaudible to the audience.
Does the P-SBOX15 need an exhaust duct?
No. The P-SBOX15 has a built-in cooling system and does not require an exhaust duct or extractor fan.
Which projectors fit in the P-SBOX15?
The P-SBOX15 family offers three models (LOWER, standard, XL) that accommodate a wide range of DCI projectors from NEC, Barco, Christie, and Panasonic.
What is the difference between the three P-SBOX15 models?
Models differ in size and projector compatibility: LOWER for smaller projectors, standard for mid-size, and XL for high-output projectors.
How is the P-SBOX15 installed in a boothless cinema?
It installs inside the auditorium using CinemaNext motorised lift options (ceiling or wall mount), with four top eyebolts for hanging.
