A-RED 47 Tube Preamp
Harmonic richness. Vintage depth. Effortless weight.
The RED 47 is not about transparency — it’s about character.
Its tube-driven design adds harmonic density and subtle saturation, bringing weight and presence to any source without sounding harsh or overprocessed.
Experience These Profiles with TSC Rack
To get the most out of these profiles, we recommend using TSC Rack — our original plugin designed specifically for Tokyo Studio Capture profiles.
TSC Rack fully supports the latest NAM A2 architecture, delivering the highest level of accuracy currently available, while also providing seamless True Stereo operation through independent Left and Right profile loading.
With its integrated profile browser, four processing slots, Auto Phase Calibration, Native Sample Rate Processing, and automatic profile management, TSC Rack makes working with NAM faster, simpler, and more enjoyable than ever.

What’s Included
A set of REDD 47 preamp profiles captured at different gain stages.
Profiles included:
-
REDD 47 – Base Gain
Balanced tone with natural harmonic warmth. -
REDD 47 – Pushed +2
Richer saturation with added thickness and forward presence. -
REDD 47 – Soft -2
Cleaner response with subtle vintage character.
Sound Characteristics
- Harmonics are enhanced, not exaggerated.
- Low-end gains weight and density.
- Highs remain smooth and controlled.
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.
Why this capture is different
- Multiple gain-stage captures for tonal flexibility
- Carefully controlled input levels during profiling
- Designed for real mixing and production use
Waveform Comparison (Hardware vs NAM)
Below is a direct comparison between the original hardware signal and the NAM profile output.
This visualization highlights how accurately the harmonic response and dynamics are preserved.
Technical notes
- Format: NAM (.nam)
- Sample Rate: 48kHz
- Capture Type: Real hardware
- Calibration: Studio-level gain staging
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.
