500R8 is the new home for 8 of your favourite 500 series modules. It's also your new 28/30 channel USB audio interface, monitor controller, ADAT interface, and discrete analogue summing mixer.

500R8 takes analogue electronics and USB integration to the next level by allowing you to utilise your favourite 500 series modules as your very own customisable tracking front-end directly into your DAW. Dedicated USB source selects for each slot and a discrete analogue summing mixer with it's own USB send allows you to bring your 500 series modules- such as EQs, compressors, and saturation devices -into your mixing process and bring analogue sound back into your workflow.

USB Audio Interface

Build your dream studio around 500R8's built-in 28-in/30-out channel USB audio interface that provides recording/playback of analogue and ADAT sources as well as connectivity via MIDI and clock distribution via Word-clock.

Monitor Controller

Control all aspects of your control room and artist monitoring setup by utilising 500R8's built-in monitor controller that includes options for Speaker A & B switching, Mono sum, Mute, Dim, and Talkback facilities.

Zero-Latency Artist Mixer

Move away from clunky software mixers and get your hands back onto the mix by using 500R8's analogue summing mixer to create artist mixes that can be blended with the DAW playback, and sent to your musicians with zero-latency.

Discrete Summing Mixer

Give your mix the final bit of analogue character and send instrument groups and stems back-through your 500 series modules, into the discrete analogue summing mixer, summed, and sent into your DAW via USB.

Digital Precision

500R8 features reference-class analogue-to-digital conversion with 121dB (unweighted) signal-to-noise ratio and a master-reference grade internal digital clock with ultra-low jitter (< 0.5 picoseconds). The combination of highly-accurate clocking and high-performance digital conversion ensures that every subtle nuance of your analogue signal is captured with the utmost detail, free of any unwanted digital artefacts from the conversion process and with a wide dynamic range due to 500R8's high-headroom and low-noise floor design.

Where to begin... There is nothing else like this box in the world. Nothing. To get the same functionality you'd need to buy a high end converter, analogue summing box, and an 8 slot Lunchbox. That works to at least triple the price of this. The workflow is like magic. I have it set up as 4 stereo modules, linked in the back with short XLR cables. Put a stereo sound into slots 1 & 2, then pull it from slot 7 & 8. Or set everything to USB and have 4 (or 8) different I/O, but there's a special magic going preamp>saturator>pultec style EQ>1176 comp. I put in something that sounds OK, and it comes out sounding like a record. I know it's cliche to talk about cream, "that thing", whatever. But my point is that you can achieve the sound of $200k of vintage gear for under $7k using this. Digital emulations absolutely cannot touch it, not even close. I was a bit uncertain about how to use the summing mixer at first. 4 stereo channels isn't much, and pulling the modules to flip the bypass switch and change the stereo pair jumper seemed like a huge pain. The solution was simple. Set everything to USB, max out the mix and pan knobs, then control how much gain is sent from the DAW. I was surprised that even summing four busses added noticable depth, space, and clarity. And keeping the modules in allows me to run the audio through them a second time. Leads go through the preamp with an API style transformer and op-amp combo (louder than liftoff), bass goes through a DIYRE pultec style EQ with everything flat, just so it hits the circuit (with vintage output again), all the little stuff goes through a LTL super filter and pentode mkII tube, and the drums go through the hairball 1176 with gain reduction off, just to get the FET and op-amp sound (kick drums don't always like that treatment fwiw). I had some minor hiccups and questions at first, and support was very quick and helpful via email. I could go on, all I can say is this was one of the best musical purchases I've ever made. I asked the makers how on earth they produced something this good for so cheap, and they said that one of the biggest reasons was keeping things simple and rock solid. I'm coming from RME, so I appreciate that mindset.
