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

Your interface, 500 series rack, monitor controller and summing mixer – all in one 4U box. The Cranborne Audio 500R8 is a USB 2.0 audio interface built around an 8-slot 500 series chassis. Plug in your favourite preamps, EQs and compressors and record them straight into your DAW, then mix through its analogue summing and monitor section.

Why customers choose it

• Huge I/O count: 28 inputs and 30 outputs over USB 2.0, including ADAT (16/16 at 44.1/48 kHz, 8/8 at 88.2/96 kHz), S/PDIF and 5-pin MIDI.
• Clean conversion: 121 dB dynamic range (A-weighted), THD+N below 0.00032% at -4 dBFS, +24 dBu max level, 44.1–192 kHz.
• Real 500 series rack: 8 high-current slots with XLR in, XLR line out and a pre-ADC TRS insert each. Send analogue, USB or C.A.S.T. signals through any module; per-slot bypass works with empty slots.
• Full monitor control: speaker A/B, mono, dim, mute, 28-segment peak meter and a talkback input with phantom power that routes to all headphones.
• Analogue summing: 8-into-2 with +26.5 dBu headroom and its own ADC; link a 500ADAT via C.A.S.T. for 16-into-2.
• Artist mixes: zero-latency mixer with level and pan per channel, DAW return blend and 2 high-power headphone outputs.

Who it is for

Project and professional studios building around 500 series gear, producers who want hardware summing, and engineers tracking bands who need independent headphone mixes and talkback.

FAQ

Can I use it without any 500 series modules?

Yes. Per-slot bypass switches let the 500R8 work as a normal interface with empty slots.

Does it have mic preamps built in?

The 8 channels use the 500 series modules you insert, such as the Camden 500 preamp. The talkback input has its own phantom power.
