The RTC600 is a studio-grade Tube Compressor Preamp in a compact Stompbox format. The RTC600 uses a precision RMS level Detection circuit and high-performance VCA to create a warm yet bold compression sound with ultra-low noise floor. Its five controls can create a wide variety of effects, including “Brick Wall” limiting and “Soft Knee” compression. Every aspect of the RTC600 has been re-thought and redesigned to provide a lifetime of trouble-free performance. The tube position comes pre-compression, adding classic valve warmth without increasing the noise level. As soon as power is applied to the pedal, an In-Rush Current control begins heating the tube at a very low voltage (much like a tube amp standby switch) to dramatically extend tube life. The RTC600 features an internal charge pump circuit that bumps the incoming voltage up to 25 volts, providing massive headroom and full-range frequency response. The RTC600 is perfect for use with any instrument or application and can be sent into an amp’s front end, placed in an effects loop, or used as an outboard processor for home recordings.
