Isonoe makes isolation products, rotary mixers and specialist audio electronics in London. Its work ranges from turntable modifications to custom mixing systems.
An Isonoe 420 rotary mixer sits between the Technics decks in Hidden Grooves’ DJ booth.
DJ mixer: 420 rotary
Inside the system
Hidden Grooves combines large Tannoy Westminster-class speakers with four TPI UC15G bass helpers, Luxman amplification and documented DSP crossover/time alignment. Tannoy miniatures provide fills or booth monitoring, while separate Technics, Leak and Grado stations support private listening.
At Spiritland, the equipment record identifies Living Voice Bespoke four-way horn-loaded satellites with 15-inch midbass. A horn-based approach can provide useful dynamic headroom, but aiming the speakers and balancing direct sound against room reflections remain central to shared listening.
Public Records should be read as several installations. The indoor Sound Room uses substantial bass and midbass sections with horn-loaded upper frequencies; the Bar Room has its own speaker and amplifier chain; the outdoor Nursery uses the OJAS × NNNN four-way system.
Shyboy HiFi lists ISONOE in its equipment list setup. The equipment details below reflect the venue record.
Equaliser: 5-Band Program Equaliser
Inside the system
Shyboy has separate Main Room, booth and Blue Room systems. OJAS × NNNN ON2 and NNNN Gage speakers form the main installation, with Powersoft amplification and a substantial selection of source and processing equipment. The booth has its own monitors and bass support.
At Dante’s HiFi, the equipment record identifies Klipsch Cornwall. The loudspeakers set the starting point for coverage and placement. A plausible reason to choose a dedicated hi-fi installation here is to give records a clear presence without relying on background-music speakers alone.
Bar Shiru lists ISONOE in its source / playback setup. The equipment details below reflect the venue record.
Rotary mixer: Custom ISO420
Inside the system
Bar Shiru’s system combines several speaker types with valve and solid-state amplification rather than imposing one chain on every listening position. The custom Isonoe mixer provides the control point for the analogue programme, with SME and VPI sources and Line Magnetic phono stages upstream.
