The RTC600 is like taking the finest studio-grade tube compressors and "squeezing" them all down into a single stompbox.

The RTC600 starts out with the same patented DBX compression circuit used in Maxon's popular CP-9 Pro+ pedal - this circuit provides a very smooth, transparent, almost "glassy" compression with very low noise floor, even at maximum settings. Your guitar sounds like your guitar, only with compression added to smooth out the dynamics.

The RTC600's dual-triode tube is positioned pre-compression, adding classic valve warmth to the signal without increasing noise levels.

With up to +30 dB of clean Gain, the RTC can be used as a clean booster or as an attenuator to clean up an already dirty amp.

The Addition of Attack and Release controls to the circuit allow for a wider variety of compression effects, including "Brick Wall" limiting and "Soft Knee" compression.

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 can be used with any instrument and for a variety of applications - it can be sent into an amp's front end, placed in an effects loop, or used as an outboard processor for home recordings.

The RTC600 features True Mechanical Bypass switching using a 3PDT switch. The RTC600 comes complete with the Maxon AC2009 9-Volt power supply, an auto sensing digital power supply that can be used anywhere in the world.

For studio-quality compression in a compact Stompbox, the RTC600 is the only REAL choice.

Rack tube compressors of this quality can cost thousands of dollars more than the RTC600.

TECH TALK:
The RTC600 features a completely new and improved circuit from its predecessor, the RCP660.

5 controls adjust the compression effect -

Threshold: Variable, 0dB to -40dB
Output gain: Variable, 0dB to 30dB
Compression Ratio: 1:1 to 1:Infinity
Attack time (for 20dB gain increase): Variable, 20mSec to 600mSec
Release time (for 20dB gain decrease): Variable, 140mSec to 700msec

A Gain reduction LED lights when the reduction is 4dB or more.

The RTC features an In-Rush Current Control system - As soon as power is applied to the pedal, a small current is applied to the tube and begins heating it at a very low voltage (much like a tube amp standby switch). This system dramatically extends the tube life. Once the pedal is engaged, 12.6 VDC is applied to the tube heater.

The RTC600 features mechanical true bypass switching via a Fujisoku 4PDT switch.

NOTE ON POWERING THE RTC600 - this pedal's voltage regulator IC requires a high inrush current of approximately 2000 mA upon startup. When using with a Power Brick such as the Voodoo Labs Pedal Power 2+, this pedal should be connected to a high current power jack when possible.
