Cranborne Audio 500R8
The 500R8 is the centrepiece of the modern studio. It's a 28-in/30-out USB audio interface that combines a 500 series rack and high-performance A/D-D/A conversion with all of the connectivity required in the modern professional or home studio.
500R8 features the studio essentials that you need to build your dream studio such as an 8-into-2 high-headroom analogue summing mixer, comprehensive monitor controller with talkback facilities, 16-in/16-out ADAT interface, as well as a zero-latency analogue artist mixer with reference-quality, high-powered headphone outputs.
The Best of Analogue
By capitalising on the vast and ever-growing 500 series market, you can configure your 500R8 to suit your tastes of analogue flavour. By installing your favourite 500 series modules into the 8 available 500 series slots, you can create your ultimate analogue front-end/preamp stage that can be multi-track recorded directly into your DAW.
Fill 500R8 full of vintage preamps for recording drums. Fill 500R8 full of clean and pristine preamps for recording strings. Fill 500R8 full of Preamp, EQ, and Compressor modules to create your own custom, analogue channel strips. The possibilities are endless and every 500R8 is unique to your sound.
Integrating 500 series modules into your workflow doesn't stop after the recording. Dedicated module source switches for each 500 series slot allow you to send USB channels from your DAW, into 500R8, through the 8 installed 500 series modules, and back into your DAW for recording (with that analogue ‘mojo’ applied). Think of 500R8 as a bank of 8 external Analogue Plug-ins.
For a more hands-on, all-analogue approach to mixing, 500R8 also features an 8-into-2 high-headroom analogue summing mixer with dedicated level and pan controls that you can use to create your own high-headroom analogue mix before recording it back into your DAW using dedicated USB inputs 9/10.
The Best of Digital
In order to capture every subtle nuance of your analogue signal, 500R8 features reference-class A/D-D/A conversion with 121dB (A-wtd) dynamic range and THD+N of <0.00032% (@ -4dBFS, 1kHz, A-wtd), all governed by 500R8’s master-reference grade internal clock with <0.5 picoseconds of jitter.
The combination of highly accurate, low-jitter clocking and high-performance digital conversion ensures that every ounce of analogue character is captured with the utmost detail - free of unwanted digital artefacts from the conversion process and with a wide dynamic range thanks to 500R8's high-headroom analogue design and low noise floor.
USB Audio Interface
Cranborne Audio's USB 2.0 audio interface provides high channel-count and low-latency performance whilst being accepted by all PC/macOS devices with unparalleled stability and longevity. 500R8 is core audio compliant for macOS or features a lightweight control panel for Windows machines that absorbs as little CPU resources as possible to leave you with more power for plug-ins within your DAW session.
Plug 500R8 into your PC/macOS device and your DAW will see a full 28-in/30-out USB audio interface. 500R8 also includes a full complement of 5-pin MIDI I/O, ADAT I/O, Word Clock I/O via BNC, and S/PDIF I/O to ensure that all of your digital studio connectivity is covered.
500R8 features a comprehensive monitor controller with connectivity for two sets of studio monitors. As well as seamless speaker switching between both sets of studio monitors, there’s a Mono button that sums L-R channels to check for mono compatibility, a DIM switch that drops the speaker volume by 12dB for relaxed discussions during recordings, and a speaker mute switch for when you are tracking with headphones.
500R8 also features a comprehensive Talkback section with XLR input, 48v phantom power, push-to-talk operation, and automatic signal routing to all C.A.S.T. and headphones outputs connected to the system.
Analogue summing can give your mix the final bit of analogue character required to achieve professional and polished sonic results. What makes 500R8's 8-into-2 channel summing mixer so special is that it is positioned after the 8 500 series slots - allowing you to insert saturation or subtle 'bus compression modules and create a stereo mix using 500R8’s dedicated analogue level and pan controls beneath each module. 500R8's summing mixer also has a dedicated converter that can be used to record your stereo mix into your DAW on USB inputs 9/10 with a massive +24dBu of headroom.
Zero-Latency Artist Mixer
500R8 moves away from clunky "virtual" software mixers and gets your hands back onto the mix. By using 500R8’s high-headroom analogue summing mixer, you can create zero-latency, all-analogue mixes of live sources that can be blended with discrete USB playback paths and sent directly to the recording musicians via C.A.S.T. or the local headphone outputs.
C.A.S.T. stands for Cat 5 Analogue Snake Transport and enables cost-effective and organised cable management around your studio. C.A.S.T. repurposes off-the-shelf, shielded Cat 5e, Cat 6, and Cat 7 networking cables to transport 4 channels of balanced analogue audio over a single cable.
500R8 has 4 C.A.S.T. IN ports that allow you to connect C.A.S.T. enabled devices (such as the Cranborne Audio N22 and N22H) and relocate I/O wherever it is needed around the studio.
Connect mic/line sources into the C.A.S.T. breakout box and that signal travels through the Cat 5 cable and directly into the modules installed into 500R8. At the same time, the analogue mix created on 500R8 is sent through the same cable and into the connected breakout box. This allows for seamless analogue audio connectivity between the control room, live room, vocal booth, or the bedroom next door!
C.A.S.T. is 100% analogue and requires no setup in order to operate. It can easily work at distances up to 100m when Cat 6 or Cat 7 cable is used, and the complete studio cabling infrastructure costs a fraction of what an analogue multicore would cost. No setup. No latency. No-fuss. And it sounds great.
