Mercury AM-16 2-Channel Preamplifier (Rare Discontinued Rackmount Version)

Up for sale is a rare, pristine Mercury AM16 Dual-Channel 19" 2U standalone rack preamp. These rackmount units are now discontinued and rarely come up for sale. It has been a trusted staple in my personal studio tracking setup for years, and I am only letting it go now to fund the acquisition of some holy grail vintage preamps.

If you are looking for the legendary, ultra-high-headroom discrete Class-A solid-state punch of the historic 1960s Langevin AM16 (one of David Marquette's favorite preamps), this is the ultimate turnkey package overbuilt with modern features and standards.

The Standalone Rack Advantage (Why this beats the 500-Series modules):

While Mercury currently manufactures a 500-series version (the AM16D), this discontinued 19" standalone rack version offers significant physical and layout advantages for a professional tracking room.

Unlike a crowded lunchbox frame where sensitive audio transformers are shoved inches away from shared, noisy switch-mode power supplies, this standalone 2U rack features an overbuilt, heavily shielded internal linear power supply with a dedicated toroidal transformer. The full-sized chassis provides massive physical isolation and superior heat dissipation, guaranteeing an incredibly low noise floor, stellar stereo crosstalk separation, and absolute hum rejection on your studio floor.

To build a dual-channel setup out of modern 500-series components today, you would spend over $2,300+ ($999 per new module plus the cost of a high-quality lunchbox frame).

Sonic Profile: The Ultimate American Class-A Color Box

If you want a distinct, elegant flavor that sets your sessions apart from standard rooms, the AM16 pedigree occupies a legendary tonal sweet spot:

API Punch meets Neve Cream: This discrete circuit is famous for holding down the middle ground between the big two architectures. It gives you the lightning-fast transient snap and ironclad low-end authority of a classic API, but strips away any harsh upper-midrange biting edge. Instead, it introduces a smooth, elegant, mid-forward presence and a pillowy harmonic bloom deeply reminiscent of a vintage British Class-A console.

The Tube-Like "Air" Characteristic: Because this is a 100% capacitor-free signal path running entirely through overbuilt custom-wound iron, the high frequencies remain completely un-smeared. It injects a lush, three-dimensional top-end sheen and open-air realism onto tracks without ever introducing artificial brightness or high-mid buildup.

Musical Transformer Saturation: The harder you push your input signals, the more beautifully the transformers behave. It doesn't fracture into harsh, clipping solid-state distortion; instead, it saturates symmetrically, thickening the midrange and adding an organic, cohesive "glue" that makes electric guitars, vocals, and drums sit perfectly in a dense mix.

A Secret Weapon for your Stereo Mix-Bus:

Because this rack features independent, variable output faders and high-input padding capabilities, its utility extends far beyond tracking. It is a spectacular tool for printing stereo mixes back through. By running your digital stems or your final stereo mix bus through the AM16's massive input and output transformer iron, you instantly impart a gorgeous, cohesive analogue glue, a wider stereo soundstage, and a velvety harmonic sheen that softens cold digital transients. It behaves exactly like running your mix through a vintage high-end console summing block.

Features & Built-In Utility:

19" 2U Format: Completely self-contained with a highly shielded, low-noise internal power section.

Fully Appointed Front Panel: Independent variable output faders, 48V phantom power switches, polarity/phase inversion toggles, and Input Pad switches (-24dB) as well as a Adjustable Input (Pad) Attenuators (-0, -6, -12, -18 and -24dB) each channel. It also has a D.I./Mic switch.

Premium Custom Iron: Custom-wound input and output transformers modeled directly after the vintage Langevin originals.

Condition:

The unit is in excellent functional and great aesthetic condition. It has spent its life securely mounted in a smoke-free, climate-controlled studio rack environment. Pots are smooth, quiet, and track perfectly symmetrically across both channels. It is a bulletproof, high-fidelity tracking engine ready to go to work on day one.
