A-PEX 351 Tape Saturation Preamp Profiles for NAM
Soft tape saturation that smooths transients while adding warmth, harmonic depth and timeless glue.
$24.99
Analog warmth. Soft saturation. Timeless glue.
The A-PEX 351 is not about distortion — it’s about depth and cohesion.
Its tape-driven character gently saturates the signal, softening transients and adding harmonic richness, creating a sense of glue and musical balance.
Audio Demo
Compare the original hardware signal and the NAM profile across a range of sources — bass, guitar, synth, and more.
Each example demonstrates how closely the profile captures the tone, dynamics, and harmonic response of the hardware.
The NAM and hardware samples are gain-matched to allow for a more accurate evaluation of the capture’s fidelity.
For additional context, a dry (unprocessed) version is also included.
The hardware used for this comparison is a single-channel unit; therefore, these demos are presented in mono to reflect its original character.
The NAM profiles themselves support full stereo operation when used on a stereo track.
What’s Included
A set of tape saturation profiles captured at different drive levels.
Profiles included:
- A-PEX 351 – Base Gain
Subtle saturation with gentle warmth and cohesion. - A-PEX 351 – Pushed Drive
Deeper saturation with thicker harmonics and soft compression.
Sound Characteristics
- Transients are rounded, not dulled
- Harmonics are enriched across the spectrum
- Natural compression adds subtle glue
Why this capture is different
- Multiple drive levels captured for tonal variation
- Carefully controlled input levels during profiling

Gain Staging Advice
Our captures are pre-calibrated at -18 dBFS input level.
For best results, we recommend feeding the plugin with an input signal close to -18 dBFS.
Due to gain reduction during the profiling process, the output level of a loaded profile may be slightly lower than the original input signal.
Please adjust the Output control to match your source level or to reach your preferred listening volume.

I’ve been looking everywhere for a proper 351 preamp emulation and most plugins sound nothing like actual unit. But this one is *it*. These A2 captures are the closest you’ll ever get to this rare unit.
