OJAS (Devon Turnbull)

Inside the system

Two OJAS installations serve separate rooms. The Live Room uses six 12-inch coaxial speakers. The Audiophile Bar combines OJAS 816 cabinets with Altec 311-90 horns, 288C compression drivers and Werner Jagusch crossovers. The bar’s February 2021 configuration includes Technics SL-1200MK2 turntables with Goldring E3 cartridges, a Urei 1620 mixer and reported McIntosh MC252 amplification. That dated configuration belongs to the Audiophile Bar and should be kept separate from the Live Room’s coaxial installation.

Inside the system

OJAS supplied a bespoke sound installation for the Dubai izakaya. Loudspeaker and amplifier models are unspecified.

Inside the system

Public Records has several distinct installations. The indoor Sound Room combines Void Nexus XL subwoofers, OJAS quad-15 slot-loaded midbass cabinets, Altec 1505B multicell horns and Faital supertweeters. Void and BGW amplification works with BSS processing; four Technics SL-1200MK2s and four Pioneer CDJ-2000NXS2s accompany a custom Isonoe mixer. The Bar Room uses replica Altec 816 midbass cabinets, OJAS cabinets with 500 Hz horns and Altec high-frequency drivers, plus Void Venu 115 subwoofers. Crown and BGW amplification accompanies analogue crossovers, with two SL-1200MK2s, two CDJ-2000NXS2s and an Isonoe mixer at the booth. The outdoor Nursery has an OJAS × NNNN fully horn-loaded four-way installation. A later Atrium installation uses six OJAS × NNNN ON M I assemblies and eight TL18 subwoofers. These room-specific systems represent different chapters and spaces, rather than components of one signal chain.

Inside the system

The Main Room combines OJAS × NNNN ON2 and NNNN Gage 125 loudspeakers with McIntosh C55 control electronics, Powersoft Unica amplification and Rupert Neve Designs and Manley processing. The signal-processing equipment includes Neve MBT, P2MB and RMP-D8 units and a Manley Massive Passive stereo valve equalizer. The booth offers ARS 9900BW, 5000 and 3500LE equipment alongside an AlphaTheta euphonia mixer, Technics SL-1200G-S decks and Pioneer CDJ-3000 players. An Isonoe five-band equalizer, Benchmark DAC3 HGC and NNNN monitoring broaden its control and playback options. The Blue Room follows a separate OJAS chain: TAD loudspeakers, a Super-sub, Phonoplayer 1200G, April phono stage and April PSET 300B amplification. The contrast between the extensively processed Main Room and the dedicated valve-amplified Blue Room is a defining feature of the installation.

Inside the system

OJAS / Devon Turnbull’s horn-loaded, Altec-inspired loudspeakers are integrated into the room through a collaboration with Steven Durr Designs and Soundlux Audio. Multiple amplifiers occupy the wall installation, while Technics SL-1200-family decks provide the vinyl source. Exact amplifier models and deck generations are unspecified. System design and acoustic work are linked to the wood-panelled interior developed with Commune Design. The installation is architectural in scope: loudspeakers, electronics and the room were considered together.

Inside the system

Devon Turnbull designed the purpose-built analog system for Mono Space. The OJAS installation is the centre of the gallery’s shared listening sessions; it is catalogued here as a custom system rather than assigned a retail speaker model.
