Cranborne Audio 500ADAT ADAT Expander & 8-Slot 500 Series Rack
Cranborne Audio 500ADAT transforms any ADAT-equipped audio interface into an analogue powerhouse by combining an 8-slot high-current 500 series rack, pristine A/D-D/A conversion, analogue summing, and zero-latency artist monitoring. With 121 dB dynamic range, sub-0.5 ps jitter, and world-class clocking, 500ADAT ensures your favourite 500 series modules sound their best in a modern DAW workflow. Expand by pairing with another 500ADAT or the 500R8, harness C.A.S.T. connectivity to reduce cabling, and enjoy a truly integrated hybrid studio solution.
Key Features
ADAT Expansion — 8-in/8-out at 44.1/48 kHz, 8-in/8-out at 88.2/96 kHz, 4-in/4-out at 176.4/192 kHz.
World-Class Conversion — 121 dB dynamic range, <0.00032% THD+N, -1 dB from 2.2 Hz to >80 kHz, jitter <0.5 ps.
Reference-Grade Clocking — internal clock with word clock I/O (BNC), sync via Word Clock or ADAT.
High-Current 500 Series Rack — 8 slots with 250 mA per rail (2 A total), gold-flash contacts, bypass switches, and source select (analogue, USB, or C.A.S.T.).
Analogue Summing Mixer — 8-into-2 summing with +26.5 dBu headroom, expandable to 16-into-2 via C.A.S.T. link.
Zero-Latency Artist Mixer — per-channel level/pan controls, aux blends, and true analogue monitoring independent of DAW latency.
Dual Headphone Amps — high-power, reference-grade headphone outputs with independent blend/level controls and linear response down to <1 Hz.
C.A.S.T. Connectivity — balanced audio over Cat 5e/6/7 cables, integrates with N22/N22H breakout boxes, transports phantom power up to 100 m.
Expandable — link with 500R8 or additional 500ADAT units for up to 16 channels of I/O, summing, and 500 series processing.
Designed & Engineered in the UK — rigorously tested with APx555 for reliability and sonic consistency.
