[. . . ] TUBE DRIVEN PROGRAMMABLE 24-BIT DSP GUITAR PREAMP Voodu Valve USER'S MANUAL TM HUSH® licensed by ® May be covered by one or more of the following: U. S. Patents #4538297, 4647876, 4696044, 4745309, 4881047, 4893099, 5124657, 5263091, 5268527, 5319713 and 5333201. Foreign patents pending. PRECAUTIONS NOTE: IT IS VERY IMPORTANT THAT YOU READ THIS SECTION TO PROVIDE YEARS OF TROUBLE FREE USE. All warnings on this equipment and in the operating instructions should be adhered to and all operating instructions should be followed. [. . . ] The COMPRESSOR RELEASE parameter determines the speed in which compression will cease after the input signal has dropped below the threshold level. COMP THRESH COMP ATTACK COMP RELEASE 20 SPEAKER SIMULATOR Function The SPEAKER SIMULATOR function is included in all presets and provides a realistic approximation of a miked speaker cabinet for applications involving connecting the Voodu Valve directly to a mixing board, recording system or other full range system. When a preset is recalled which has the Speaker Simulator on for either the left channel or both channels, the front panel SPKR SIM LED will light. Note: The parameters provided in this function are operational only when the SPKR SIM parameter under the Global function is stored UNLOCK, LOCK L or LOCK B. The PARAMETER SELECT control will allow you to access these SPEAKER SIMULATOR parameters: SPKR SIM I/O The SPEAKER SIMULATOR parameter allows you to select whether the Speaker Simulator is on for BOTH outputs, on for only the LEFT output or OFF. The SPEAKER TYPE parameter determines the type of speaker to be simulated. 15", 12", 10", 8" and full range speakers are available. The MIC PLACEMENT parameter simulates a microphone placed anywhere from the center of the speaker cone out to the edge of the cone. Positive parameter values simulate moving the microphone toward the center of the speaker, while negative values move it to the edge. The REACTANCE parameter simulates the characteristics of the the interaction between a tube amplifier and a guitar speaker cabinet. The higher the parameter value selected, the more these characteristics will be apparent. Negative values of reactance can be used to simulate an open-back cabinet. SPKR TYPE MIC PLACEMENT REACTANCE 21 WAH-WAH Function The WAH-WAH function is available only in configurations which display "WAH" in the configuration title. The Voodu Valve has an internal wah-wah which allows for an expression pedal to be used as a wah-wah pedal through continous control changes. Use of this feature eliminates the need to run long audio cables out to a conventional wah-wah pedal. To use an expression pedal as a wah-wah pedal, connect it to a MIDI controller (such as a Rocktron MIDI Mate) and set the controllers MIDI channel to correspond with the Voodu Valves receiving MIDI channel. Then set the pedals control number on the MIDI Mate to match the Wah Frequency parameters control number on the Voodu Valve. This control number is set on the Voodu Valve in the "CONTROLLER ASSIG" function. (See "Controller Assignments" in Chapter 8 for more information on assigning control numbers. ) The PARAMETER SELECT control will allow you to access these WAH-WAH parameters: WAH-WAH I/O The WAH-WAH I/O parameter determines whether the wah-wah is active for the current preset. The WAH FREQUENCY parameter allows you to manually sweep the frequency range of the wah-wah via the PARAMETER ADJUST control. Selecting a frequency for this parameter and storing the WAHWAH parameter IN allows you to use the wah-wah as a fixed wah. WAH FREQ 22 PHASER Function The PHASER function is available only in configurations displaying "PHAS" in the configuration title. Phase shifting involves splitting the input signal into two signals, then shifting the phase of different frequencies of one signal and mixing it back with the original signal. The PARAMETER SELECT control will allow you to access these PHASER parameters: PHASER I/O The PHASER I/O parameter determines whether the Phaser is active for the current preset. The DEPTH parameter determines the modulation depth of the phase shift effect. Higher parameter settings result in the sweep of the filtering effect occurring over a wider frequency range. The RATE parameter deterrnines the speed at which the phase shifted signal is modulated. [. . . ] The Voodu ValveTM will display "INITIALIZING" as the Voodu ValveTM memory is restored. INITIALIZING After the All Restore process is completed, the display should read "ERRORS 0". This is the number of bytes that the Voodu ValveTM found that did not initialize properly. Any number of errors other than "0" means that the Voodu ValveTM may not have initialized properly and the process should be repeated. ERRORS 0 The Voodu ValveTM will remain in this condition until the FUNCTION SELECT control is turned to exit the Factory Restore function. The preset currently recalled will be the preset most recently restored into the current location. Restoring the Voodu ValveTM controller assignments: The controller assignments for the Voodu Valve can also be reinitialized without affecting presets and other stored information. [. . . ]
