Use the 500R8’s two aux buses to create pristine analog cue mixes that you can blend with DAW playback and send to the talent with zero latency.
World-class conversion and clocking
For the musician who wants to get down to business, it may be hard to get excited about conversion and clocking. But engineers at Sweetwater get to check out the best of them — and we’re amped about these converters. They’re touted as best-in-class and flaunt truly impressive specs such as under .5 picoseconds of jitter. But none of that really matters when you hear the fullness of your stereo image bloom with jaw-dropping sonic clarity.
Connect the 500R8 to your macOS or Windows computer and capture every nuance of your sources with reference-grade AD/DA conversion and world-class internal clocking. Effortlessly pass audio between analog and digital worlds without the digital artifacts that color, cloud, and degrade your recordings. The only coloration you will hear is intentional — your microphone placements, mixing decisions, and the 500 Series modules you’ve chosen to use. And with word clock I/O, you can even share the 500R8’s world-class clocking with the rest of your digital gear.
Ample I/O and configurable front end
The 500R8 has generous I/O to integrate with all of your analog and digital hardware, so you can mix and match your 500 Series modules and find the best combinations during recording and mixing to help create your own signature analog sound. You can even integrate your 19" rack units via the 500R8 s dedicated per-slot TRS insert jacks.

| In today’s modern age of digital recorders, DAWs and software plug-ins, Mike-E is the ultimate solution for getting a clean and strong, yet warm and musical signal into the box…and it couldn’t be easier to work – its front panel layout is so straight ahead that even inexperienced engineers will have no problem moving around on it right away.
When the engineering team at Empirical Labs sets out to build a microphone preamp, you can be sure it’ll deliver spectacular sound, be effortless to work, and will provide features unlike any other device in its class. To that end, we proudly present Mike-E, a high performance transformer-coupled mic preamp with a noise floor far below any microphone’s self noise, combined with a one-of-a-kind compressor/saturator circuit that delivers classic knee compression as well as versatile tonal ‘coloring’ that can replicate many of the best characteristics of vintage analog recording equipment.
Mic Preamp
The Mike-E features a super low noise transformer input amplifier section with the gain under precise digital control. The signal to noise far exceeds any microphone in existence. Having used many mic preamps over the years, we’ve implemented a unique stepped gain control that should be impervious to the normal flakiness that age causes to pots and detented switches. A “Bad!” LED indicates when the input signal is overloading the circuit.
CompSat
The CompSat’s unique circuitry sets the Mike-E apart from all other mic preamps.
- SATURATOR – a multi stage soft-clipping circuit. At lower levels, a triode-type saturation affects the signal. As the level increases, a second unique clip circuit starts to more severely flatten out the peaks.
- COMPRESSOR – based on ELI’s world famous Distressor, but with other characteristics (including a much longer attack time). Preset ratios include: 2:1, 4:1, 8:1…and, of course, Nuke.
- EMPHASIS – a two-stage circuit that boosts and soft clips high frequencies before the CompSat™ circuit, and then cuts the frequencies after it. Emphasis has the added perk of improving signal to noise, and is the reason analog tape decks used emphasis to begin with.
Frequency Response: 3 Hz to 200 kHz on (No CompSat). CompSat is 3Hz – 150Khz. Optional Transformer output is 6Hz–80kHz.
Signal to Noise: 130 dB signal to Noise.at 40dB gain. Maximum output is +28dBu.
Distortion: Ranges between .0006% and 15% depending on mode and settings.
I/O: Transformer coupled Input, Active and Transformer Outputs available. High quality audio caps used internally.
Impedance: Input Impedance is above 600 Ohms at all frequencies, transformer coupled. Output impedance is less than 38 ohms. Instrument In Impedance is 332K Ohms.
Attack/Decay Range: .9 – 70mS attack. .15 – 1 Sec.
Power Consumption: 15 Watts Max.
Metal Chassis: single height 1.75″ high, 10″ deep, 19″ wide. | Firmly rooted in six decades of console design experience, the 5057 Orbit gives your mixes the legendary tonality, power, and wide-open soundstage that only Rupert Neve’s class-A analog summing can provide. Coupled with Rupert’s famous custom audio transformers and Silk Red & Blue circuitry for variable harmonic saturation, the Orbit launches sterile in-the-box mixes to new heights of tone, depth and clarity – without compromising the recallable convenience and repeatability of your DAW-based workflow.
When you push a mix buss and output transformers towards saturation, the non-linear, musical harmonics that occur are what truly glue a recording together and bring it to life.
Rather than using an external summing solution that offers little more than an ultra-clean representation of the in-the-box experience, the Orbit provides the extraordinary richness, harmonic complexity and depth that only a Rupert Neve console can bring to your mixes.
The Orbit utilizes a highly custom output transformer configuration originally developed for the acclaimed Shelford Channel, which provides both a Main Output and a -6dB Output – the latter of which enables you to fully drive the Orbit to achieve more transformer harmonics without clipping the next device in the chain. This unique transformer drive is a hallmark of the sound of Rupert Neve throughout the years – and the sound of countless classic hit records.
Classic Sounds on Demand
Every mix demands its own treatment. In addition to the choice of outputs, the continuously variable Texture control with Silk Red and Silk Blue modes gives you complete control over the harmonic density and tonality of your mix – or lets you keep it utterly pristine and uncolored.
The Silk Red mode accentuates transformer saturation in the high and high-mid frequencies to amplify the vibrant midrange harmonics associated with Rupert’s vintage equipment, while Silk Blue accentuates saturation of the lows and low-mids to add thickness and weight to any source – especially useful for “thin-sounding” mixes. Unlike EQ, these Silk & Texture controls saturate the output transformers, and add highly musical harmonics to the source material according to the amount of Texture applied.
Drive the mix buss hard, choose your Silk flavor, and crank the Texture knob for a rich, saturated, vintage vibe – or disengage Silk entirely for clear, wide-open sonic beauty. The choice is yours.
Build your Dream
While the Orbit is an extremely effective tool on its own, multiple units can be combined through the Buss Link for a higher channel count. The 5057 Orbit can also be used as a building block in an expandable summing system utilizing the 5059 Satellite for flexible summing & routing, and the 5060 Centerpiece for additional mixing and monitoring features.
These units create the core of a world-class analog modular console system rivaling any traditional large-scale studio setup.
Channel Separation and Accuracy
With precisely fixed channel levels and accurate mix buss attenuation via high-quality stepped switching, the Orbit’s purist signal path has vanishingly low crosstalk, and channels matched to within +/-0.1dB. This provides your mixes with the widest and most accurate stereo image, the greatest depth, and the most direct signal path, allowing you to hear every single detail of your mixes.
DAW Based Recall without Compromise
Frequent recalls can be a challenge for modern mix engineers. The Orbit’s elegant simplicity and fixed level accuracy provides rapid, repeatable DAW-based recall from mix to mix, while adding the rich, unrivaled sound quality of Mr. Neve’s class-A transformer-coupled mix buss.
