User manual DIGITECH RP20

[. . . ] Tube Preamp/Effects Processor & Controller User's Guide Please visit Digitech Electronics on the World Wide Web at http://www. digitech. com WARNING CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN FOR YOUR PROTECTION, PLEASE READ THE FOLLOWING: WATER AND MOISTURE: Appliance should not be used near water (e. g. near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc). Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings. POWER SOURCES: The appliance should be connected to a power supply only of the type described in the operating instructions or as marked on the appliance. [. . . ] This parameter is used emulate the the time that it takes to get the Speaker up and spinning at full speed. The parameter can be assigned to a footswitch or the expression pedal so you can control the acceleration speed. Rotary Speaker Simulator Parameters: FX: Lvl Dry: Lvl Balance Mode Spread H - R: Level Controls the signal input level fed to the Module. Ranges from -99 (all left) to 99 (all right) Selects which speed mode the Rotor and Horn are in. Ranges from Off to 100%. 40 User Guide RP-20 Valve Slo - Fast Hrn Speed Slo - Fast Hrn Depth Section - 4 Editing Modules Controls the Low Frequency Oscillator (LFO) speed of the Horn. Ranges from 0 to 30 milliseconds. Slo - Fast Hrn Doppler Sets the amount of shifted pitch heard in the Horn. Slo - Fast Rtr Speed Slo - Fast Rtr Depth X-Over Acceleration: H - R Controls the Low Frequency Oscillator (LFO) speed of the Rotor. Selects the frequency where the signal is split between the Horn and Rotor. Sets the amount of time that the Rotor and Horn take to come up to their full rotating speed. Ranges from 0 to 10 seconds. Tremolo and Auto-Panner Look out, because the popular Tremolo and Auto panner effects of the 50's and 60's are back with a vengeance. These effects that revolutionized "Surf-Style" music can be heard all over the air waves in the 90's. Tremolos and auto panners are similar to one another in that they both use an LFO to modulate input levels to produce vibrato effects. Tremolo The word tremolo actually has several definitions in the music world. It basically means that a sound is being modulated in amplitude (the volume is beating or pulsing). But you probably have better things to do than turn a volume control up and down throughout a whole song, so let the RP-20 Valve do it for you. Aside from speed and depth parameters, the tremolo also has an LFO waveform that determines the way a signal's volume is increased and decreased. While the Sine wave is probably the most common to the ear, the Triangle and Special 2 waveforms are progressively more intense. When do I use Tremolo?Tremolo is truly a vintage sound for the guitar, electric piano and organ. Most pronounced on the guitar, you can hear it used on everything from sweet ballads to blues rock 'n roll. Auto Panner The auto panner is really just a dual version of a tremolo. It changes the amplitude of the left signal just as a tremolo does, but the amplitude of the right signal is inverse to that of the left signal. This gives the illusion that the signal is moving back and forth between the left and right speakers. The Auto Panner's Speed typically doesn't get set as fast as the Tremolo since you usually want a sound to move smoothly back and forth in the stereo image. The Millennium auto panner is especially flexible since it can be used for either mono or stereo input sources. When used with a mono source, the signal pans back and forth as described earlier. [. . . ] Current value for the wth parameter. The Receive All Current Parameter Values procedure is used to receive Parameter Values from the RP-20 Valve for the currently selected program. Warning: Sending data that was retrieved from a different program will delete the memory. Be sure to only send data that was received from the same program. REQUEST MODULE CONFIGURATION (25h) SYS HEAD , 25 (h) , F7 (h) When a Request Module Configuration procedure received, the RP-20 Valve will respond with a Respond Module Configuration procedure.
