Cranborne Audio 500R8 USB Audio Interface and 8-Slot 500 Series Chassis

Cranborne Audio 500R8 USB Audio Interface and 8-Slot 500 Series Chassis

The Cranborne Audio 500R8 USB audio interface and 8-slot 500 Series chassis is an all-in-one analog/digital hybrid recording hub that combines an 8-slot high-current 500 Series rack, a 28-in/30-out USB audio interface, an 8-into-2 analog summing mixer, a comprehensive monitor controller with talkback, a 16-in/16-out ADAT interface, and a zero-latency analog artist mixer into a single 2U unit. As a result, the 500R8 can serve as the complete centrepiece of a professional studio, handling everything from module hosting and recording to monitoring, summing, and headphone distribution without additional outboard hardware. The 500 Series rack section delivers 250mA per slot with a 2A total current budget, providing ample headroom for even power-hungry modules. In addition, reference-class A/D-D/A conversion offers 121dB dynamic range and THD+N of less than 0.00032%, supporting sampling rates up to 192kHz for pristine digital conversion. OneStopMusic South Africa stocks the Cranborne Audio 500R8 USB audio interface and 8-slot 500 Series chassis for studios across South Africa wanting to consolidate their entire studio front end into one well-engineered unit.

Complete Studio Integration From the Cranborne Audio 500R8 USB Audio Interface and 8-Slot 500 Series Chassis

Whether you're tracking through 500 Series preamps, running a hybrid mix through the analog summing section, or distributing headphone feeds to a live room via C.A.S.T., the Cranborne Audio 500R8 USB audio interface and 8-slot 500 Series chassis handles it all from a single rackmount unit. The monitor controller section includes a talkback input with XLR connector and 48V phantom power, push-to-talk operation, and automatic signal routing to all C.A.S.T. and headphone outputs in the system. Two front-panel headphone outputs — Monitor and Aux — deliver up to 1.21W per channel into 100 ohm loads, providing powerful, clear monitoring through any headphones. However, the 500R8's connectivity extends further still: ADAT optical for up to 16 additional channels, S/PDIF, 5-pin MIDI, and Cranborne Audio's proprietary C.A.S.T. system for distributing audio across the studio via standard Cat 5 cable. OneStopMusic South Africa recommends the Cranborne Audio 500R8 USB audio interface and 8-slot 500 Series chassis to South African engineers and studio owners who want a single, comprehensive unit that covers every aspect of a professional recording setup.

Cranborne Audio

Founded in the UK in 2017 and launched at the 2018 NAMM Show, Cranborne Audio set out to bring a "modern approach to vintage sound" to project, large-format, and home studios. The name nods to Cranborne House, the former Soundcraft headquarters where the founders first worked together — and that pro-console heritage shows up throughout the range. Cranborne's products pair transparent, high-headroom analog signal paths with switchable Mojo saturation circuits, letting engineers dial in vintage colour on demand rather than being stuck with it.
