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.
