TL Audio 5021 MKII 2-Channel Tube Compressor

Valve compression is now universally recognised as one of the essential tools for today’s recording engineer. The Ivory 5021 provides everything you would expect from a TL Audio compressor - first class audio quality, bags of flexibility and a price tag so modest you'd be forgiven for thinking it was a printing error! Now the new 5021 features hard and soft knee modes, four attack and release times, an improved optical gate design and an optional digital output. Like the C-1 compressor, the 5021 uses our own special transconductance amplifier design that avoids the use of VCAs - ensuring maximum audio transparency. So whether you’re hitting the end stops or just providing gentle dynamic control, the 5021 delivers super-smooth results every time!
 
The 5021 employs two valve stages per channel, in the form of a Sovtek ECC83/12AX7A twin triode valve run from a stabilised 150V DC supply. One stage is in the preamp, and the other is in the gain control element of the compressor.

Verdict,
 
Not recommended on the mix bus. FMR RNC is a better choice at this price point. Opinion about this product is reflected in the vast numbers that are listed on ebay & other used audio sites every week. Some users complain about that valves not affecting the sound much. There are better alternatives. If you are after a transparent compressor, the FMR RNC will do a better job. If you are looking for a compressor for colouring your sounds, look for the Symetrix 501 (toggle switch) or the Ashly SC-50.
