AMS Neve RMX16 500 (2020–Present)
The unmistakable shimmer of 1980s studio magic, reborn in a 500-series slot—bright, bold, and built for modern tracking with a vintage soul.
Overview
The AMS Neve RMX16 500 brings back the digital design of the original RMX16, the unit used on records by Peter Gabriel, Kate Bush, and Tears for Fears. It fits in a lunchbox. Nonlin2 on a snare is the sound of gated reverb, and producers in 1983 stopped mid-mix for it. You don't need a full rack or a six-figure studio budget to get it now. You need a 500-series chassis.
This isn't a clone or a loose interpretation. It's the same algorithms, ported bit-for-bit from the original 1982 firmware, running on modern hardware that's quieter and more stable. The original RMX16 was the first microprocessor-controlled, full-bandwidth digital reverb. No tape loops, no springs, no plates. The sound was crystalline and sometimes slightly grainy, and it felt alien next to the warm analog reverbs of the time. It didn't try to mimic a concert hall. Over four decades later, it comes in a three-slot module that draws less power than a nightlight.
The RMX16 500 is a mono-in, stereo-out processor, like the original. It has no convolution impulses and no modulated tails, and there isn't much to tweak. It offers 18 distinct programs: nine from the original launch, and nine rare "barcode" programs that once needed a physical wand and a printed sheet of barcodes. Studio techs would curse as they waved the reader over smudged paper, hoping the unit wouldn't crash mid-scan. All 18 are now available from the front panel, no wand required.
The front panel copies the original's calculator-style keypad. The red OLED display stands in for the old LED readouts, and the rotary encoder has the same slightly chunky resistance. You adjust decay time while listening, nudge values up and down with the dedicated buttons, and save your tweaks to one of 100 user presets. The original had no dry/wet mix control (it was all reverb, all the time). This version has a blend knob, so it works as an insert effect during tracking or mixing.

Key Features
The Sound of the 1980s, Faithfully Recreated
The RMX16 500 doesn’t just emulate the sound of the original—it is the original’s sound, just cleaned up. The algorithms are identical, ported directly from the original code by Mark Crabtree, the unit’s original designer. That means Ambience still has that bright, airy shimmer that cuts through a dense mix. Plate A1 remains dense and slightly chorused, perfect for vocals or snare. Room A1 gives you that short, thick slap that makes instruments feel present without drowning them in space. And Nonlin2? That’s the one. The gated reverb that defined an era, with its explosive attack and abrupt cutoff. It’s not subtle. It’s not natural. It’s pure drama. Turn it up on a snare, blend in a little dry signal, and suddenly you’re in the middle of a Phil Collins fill.
The nine "barcode" programs were originally distributed on printed sheets and loaded via a wand. They include Image P1, which pans the reverb across the stereo field, and Freeze, which creates an infinite sustain. These were rare even in the 1980s. The processing is 32-bit with 24-bit converters, so the overall sound is cleaner, quieter, and more detailed than the original. The unit also models the behavior of the original's 16-bit processing and 18 kHz bandwidth, so you can get the slightly gritty, vintage digital character without the noise floor.
Tactile Control in a Modern Format
In an age of mouse-clicking and menu diving, the RMX16 500 feels refreshingly hands-on. The endless rotary encoder lets you sweep through parameters in real time, while the nudge buttons allow for precise ±1 adjustments. The keypad isn’t just for show—you can type in exact values for decay time, pre-delay, or filter settings. It’s fast, intuitive, and forces you to engage with the parameters rather than just turning a knob and hoping.
The OLED display is small but sharp and legible. It shows program names, parameter values, and a traffic-light-style input meter. It's monochrome red, like the original's LED displays. It has a bouncing logo screensaver, which some users find distracting, but it's easy to disable once you know how. The front panel layout is tight but logical, with all essential controls within easy reach. It's not as spacious as the original 2U rack unit, but that's the trade for fitting into a 500-series rack.
Modern Workflows, Vintage Soul
The biggest functional change from the original is the wet/dry mix control. The vintage RMX16 had no such thing. It was all reverb, all the time, so engineers had to use it in a send/return loop. The 500 version adds a blend knob, so you can track with it, print effects in real time, or use it on a bus without an extra aux send.
There are 100 user presets, so you can save tweaks like a bright Ambience with shortened decay for vocals, or a darkened Room for guitars. The original had no memory beyond the nine factory programs (and the nine barcode ones, if you had the wand). The front-panel USB port doesn't allow remote control or DAW integration. It does support firmware updates.
Historical Context
The original AMS RMX16 redefined the market. Before 1982, digital reverb was either nonexistent or prohibitively expensive. Lexicon had the 224, but it cost more than a car. The RMX16 was more affordable, and it sounded different: brighter, bolder, less polished. It wasn't trying to be realistic. It was trying to be exciting.
It evolved from the DMX15R, a processor that had no analog I/O and had to be connected to the back of the DMX15-80 delay line. The RMX16 was the first fully standalone version, with its own converters and power supply. It became a staple in British studios - Livingston, Townhouse, Abbey Road - and its sound spread across pop, rock, and new wave. Hugh Padgham used it with the SSL's gated mic to create the gated reverb effect on Phil Collins' "In the Air Tonight."
By the 2000s, original units were becoming rare, fragile, and expensive. Vintage King lists them at around $3,000 in good condition. Universal Audio released a plug-in in 2014 that captured the sound remarkably well, but hardware enthusiasts still wanted the physical unit. The RMX16 500 launched in 2020.
Collectibility & Value
The RMX16 500 is a new product, still in production, and widely available. It has become a sought-after tool in modern studios, especially among engineers who want the 1980s sound without the maintenance headaches of vintage gear. At $1,295, it's not cheap, but it's a fraction of the cost of a vintage unit, and it comes with a warranty.
Condition isn't a concern the way it is with 40-year-old electronics. There are no aging capacitors, no failing fans, no corroded ribbon cables. The unit is solid-state, with no moving parts, and it runs cool. Failures are rare, and when they do happen, they're usually power-related, so make sure your 500-series chassis has a sturdy power supply. The front-panel USB is only for firmware updates, so there's no risk of computer interference or driver issues.
If you're buying used, check that the OLED display works, the encoder turns smoothly, and all buttons respond. Some early units had firmware bugs with preset saving, but these have been patched. Avoid units with physical damage to the encoder knob or display - it's not user-serviceable. Otherwise, this is one of the most reliable pieces of 500-series gear on the market.
Vintage RMX16 units still command $2,500-$3,000, but they require maintenance. The fan can fail, the power supply can degrade, and the internal memory can corrupt. The 500 version eliminates those worries while preserving the sound. It's not a replacement for the original.
