Select the HIGH input jack for extra gain, or the LOW input jack for normal gain. 2 GAIN controls (CLEAN and OVERDRIVE) Adjusts the amount of amplification in the preamp section. More gain increases distortion, reduced gain results in a clean sound. OVERDRIVE is designed with increased gain while CLEAN has less built-in gain. LEVEL controls (CLEAN and OVERDRIVE) The LEVEL controls adjust the overall volume for each channel. Once the gain is set, adjust the LEVEL control for the appropriate listening volume. PRESENCE control Increasing the amount of PRESENCE (turning the knob clockwise) will increase the definition of the notes played. REVERB control Adjusts the amount of reverb added to your guitar's signal. When pushed again, CHORUS is shut off. 3 4 5 6 7 8 2 9 CHORUS DEPTH and RATE These two controls affect the depth or amount of chorus and the rate or speed of the chorus sweep. A lower DEPTH setting will produce a more subtle detune effect, while a higher setting will produce a more extreme detuning effect. [. . . ] The AGXTM circuit expands the gain of the amplification circuit only when required based on the input level. When no signal is present, the AGXTM circuit expands down the amplification level to a point where hum and noise are dramatically reduced. 3 R50C Specifications Power Output Speaker Parameters Dimensions Weight Power Requirement 50 Watts (25 Watts per channel) 2 x 8" Velocity® High Definition by Rocktron 15" H x 20. 9"W x 9. 8"D (381 x530 x 250mm) 26. 16lbs.
