RTC600 Real Tube Compressor/Limiter

The Maxon RTC600 Real Tube Compressor/Limiter is a studio-grade compressor with a real vacuum tube, offering warm yet bold compression/limiter sound. It features low noise and wide dynamic range with a precise RMS level detecting circuit and high-performance VCA (voltage controlled amplifier). The RTC600 provides studio-level settings with three controls (THRESHOLD, RATIO, GAIN) and two envelope controls (ATTACK, RELEASE).

Key technical specifications include:
- Input Impedance: 500k ohms
- Output Impedance: 10k ohms
- Maximum Output Level: +20dBu (at 1kHz)
- Residual Noise: -94dBu or less (Input shorted, IHF-A weighted)
- T.H.D.+N: 0.02% or less (at 1kHz, -10dBu output)
- Power Supply: Maxon AC adaptor
- Power Consumption: 240mA/9VDC
- Internal Circuit Voltage: ±12.5V (DC to DC Converter)
- Dimensions: 121(W)×152(D)×60(H)mm (with protrusion)
- Weight: Approx. 580g (without AC adaptor)

The RTC600 offers variable threshold level (0dBu to -40dBu) for optimal compression settings, a variable compression ratio from 1:1 to infinity:1, and variable output gain (0dB to 30dB). It also features "Brick Wall" limiter and "Soft Knee" compression effects, as well as true mechanical bypass switching using a 4PDT switch.

The pedal is designed with a high-headroom and full-range frequency response, allowing it to be used with any musical instrument. Additionally, it includes a tube heater inrush current control circuit to extend tube life and is FCC Part 15 compliant and RoHS compliant.

The RTC600 is suitable for a variety of applications, including being sent into an amp's front end, placed in an effects loop, or used as an outboard processor for home recordings. It is a compact stompbox that provides studio- quality compression and is suitable for professional use.
