Millennia TCL-2 STT-1 Compression Demo Video

Millennia's TCL-2, Twincom compressor is the same compressor in the STT-1 Origin Mic Pre. The clean and transparent Twincom compressor can be used for recordings of any genre. In this demo, we show its use on saxophone, double bass, and female vocals. The compressor can be used on individual mono channels or linked for stereo channels. The compressor is fast enough and includes a 30:1 ratio option in order to use it as a limiter as well. The TCL-2 and the STT-1 both feature two paths, a J-FET solid state signal path and an all triode 300 V vacuum tube signal path, using Millennia's patented Twin Topology. If you have any questions about this fantastic compressor or any other pro audio equipment, don't hesitate to call us today at Sound Pure. 919.682.5552
