The original maker's reissue of the classic FET limiting amplifier.
Not for: Buyers on a budget, who get most of the sound from clones.
What the AI looks for in Effect Processor Compressors
- Detector topology
- FET for fast, aggressive control; opto for smooth vocals; VCA for precise bus work; vari-mu for gentle mastering. The circuit type sets the sound and use more than any feature list does.
- Attack range
- Sub-millisecond attack for peaks on drums and vocals; slower attack to let transients through. Attack time decides whether the compressor catches or preserves transients.
- Stereo linking
- Bus use needs a true stereo or linked pair. Unlinked channels shift the stereo image when one side compresses harder.
- Sidechain
- Prefer a sidechain high-pass filter or external key input. Without it, the compressor pumps on bass energy.
- Metering
- Clear gain-reduction metering. You need to see how hard the compressor is working while tracking.
Brands that matter
- Universal Audio: The original 1176 and LA-2A designs, reissued.
- Warm Audio: Value-priced clones of classic compressors.
- dbx: Durable VCA workhorses for live sound and utility.
- SSL: The reference VCA bus compressor sound.
- FMR Audio: The RNC series: clean, inexpensive, studio-respected.
- Empirical Labs: The Distressor: an extremely versatile modern classic.
What to avoid
- Unbranded clones with no stated detector type.
- Single-channel units for stereo bus duty.
- Compressors without gain-reduction metering.
Questions
Hardware or plugin?
Hardware matters mostly when tracking, to commit compression on the way in. For mixing, good plugins are close enough for most users.
