Independent shopping perspective
The Korena take
WA76-D is a single-channel clean-gain discrete FET compressor based on a vintage 1976 Revision D-style circuit. It puts attack, release, ratio, input, and output controls at the center of its workflow, then adds a dry/wet mix for parallel compression, selectable input impedance, stereo linking, and a variable sidechain high-pass filter. Custom CineMag O-12 input and 5002 output transformers, along with premium capacitors and resistors, shape its analog signal path. The unit is housed in a 2U rackmount chassis and is hand-tested and inspected.
Strong match
Who this is for
- Single-channel studio compression with fast timing controls and a Revision D-style circuit.
- Parallel-compression routing from the unit's dry/wet mix control.
- Adjusting how 30–300 Hz content influences the compressor through its sidechain filter.
Consider the trade-offs
When to look elsewhere
- Stereo compression from one unit; stereo linking requires another WA76-D.
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
CineMag O-12 input and 5002 output transformers
These specific custom transformers are used in the analog signal path.
Detail 03
20 µs–800 µs attack; 50 ms–1.1 s release
Provides variable timing controls for compression.
Detail 04
30–300 Hz sidechain high-pass filter, 12 dB/octave
Lets you filter low frequencies from the compressor sidechain over that range.
Detail 05
2U rackmount chassis
Occupies two rack units.
Final check
Know before you order
- 01Stereo linking requires another WA76-D.
- 02Plan for two rack units of installation space.
