  • Page 13: Front Panel

    The Voodu Valve provides 254 stored sounds called presets . Any of the 254 presets can be called up at any time via the front panel PRESET control (used to select a preset) and RECALL button (used to call up the selected preset), or by a remote MIDI footswitch. The root of each preset’s sound is its configuration .
  • Page 14 Voodu Valve Functions and Parameter Descriptions Each Voodu Valve preset is divided up into individual blocks called functions (such as "Mixer", "Reverb", etc.). Within each function of each configuration is a set of controls which allow you to manipulate various aspects of that function. These controls are called parameters .
  • Page 15 The MUTE parameter allows you to mute the output of the Voodu Valve. This feature is especially useful when changing guitars during a live set. If a Rocktron All Access™ is used in remote mode with the Voodu Valve, a single All Access button can be configured as a momentary switch which will mute the output when it is held down.
  • Page 16 The next function displayed after turning the FUNCTION SELECT control is the Mixer function. The Mixer function parameters are included in all presets—regardless of which configuration is currently recalled—although the parameter values stored in this function are only for the currently recalled preset. This digital mixer allows you to control most signal levels pertaining to each preset’s configuration and stores these levels for each preset.
  • Page 17 The HIGH GAIN function is only accessible in configurations which display "H-GAIN" in the configuration title. The preamp stage in these configurations is set up to provide high gain levels for maximum sustain and distortion. The PARAMETER SELECT control will allow you to access these High Gain parameters: TUBE GAIN The TUBE GAIN parameter sets the amount of drive at the input of the tube stage.
  • Page 18 The LOW GAIN function is only accessible in configurations which display "L-GAIN" in the configuration title. The preamp stage in these configurations provides four distortion types, and can also be used for clean tones. The PARAMETER SELECT control will allow you to access these Low Gain parameters: TUBE GAIN The TUBE GAIN parameter sets the amount of drive at the input of the tube stage.
  • Page 19 The HUSH ® function is accessible in all presets—regardless of the configuration currently recalled. HUSH is Hush Systems’ patented single-ended noise reduction system. The HUSH system contained in the Voodu Valve, though modeled after the latest analog HUSH design, is a fully digital implementation achieved through Digital Signal Processing (DSP).
  • Page 20 The PRE EQ (EXPERT) function is available in all presets—regardless of which configuration is currently recalled. This function allows you to shape the tone prior to the distortion stage. Considerable tone variations can be achieved by modifying these pre-distort EQ parameters. The PARAMETER SELECTcontrol will allow you to access these PRE EQ parameters: LF LEVEL The pre-LF (low frequency) LEVEL parameter allows you to cut or...
  • Page 21 The POST EQ (EXPERT) function is available in all presets—regardless of which configuration is currently recalled. This function allows you shape the tone after it has passed through the distortion stage. These post-distortion EQ parameters have a more dramatic effect on the overall tone than the pre-distortion parameters.
  • Page 22 The COMPRESSOR function is available only in configurations which display "L- GAIN" in the configuration title. This function allows you to compress the signal prior to the distortion stage. Com- pression is often used to maintain an even level when using clean tones, and also to increase sustain when using distorted tones.
  • Page 23 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.
  • Page 24 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 controller’s MIDI channel to correspond with the Voodu Valve’s receiving MIDI channel. Then set the pedal’s control number on the MIDI Mate™...
  • Page 25 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...
  • Page 26 The FLANGER function is available only in configurations displaying "FLAN" in the configuration title. Flanging involves splitting the input signal into at least two individual delayed signals (Voice 1 and Voice 2) , then modulating these delayed signals so that, when summed back with the direct signal, phase cancellations will occur at some frequencies while peaks in the response will occur at others.
  • Page 27 The TREMOLO function is available only in configurations displaying “TREM” in the configuration title. The Tremolo effect continuously varies the volume of the signal. The PARAMETER SELECT control will allow you to access these TREMOLO parameters: TREMOLO The TREMOLO I/O parameter determines whether the Tremolo is active or bypassed for the current preset.
  • Page 28 The PITCH function is available only in configurations displaying “PSHF” in the configuration title. Pitch Shifting is used to change the pitch of the input signal to produce a harmony note based on the input signal. The harmony voice may be of any fixed interval—up to one octave above the input signal to two octaves below—and is selected in 20-cent increments.
  • Page 29 20 cents).This allows for smooth pitch change when an expression controller (such as a volume ™ ™ pedal used with a Rocktron All Access or MIDI Mate foot controller) is assigned to the PITCH parameter to change the pitch by remote means.
  • Page 30 The CHORUS function is available only in configurations displaying “CRS” in the configuration title. The Chorus effect in the Voodu Valvedddd is produced by using two delayed signals (Voice 1 and Voice 2), detuning these delayed signals (slightly changing their pitch), then modulating the detune effect so that the amount of pitch detune is constantly varying.
  • Page 31 PAN 2 The PAN 2 parameter allows you to pan Voice 2 to the left or right channel. DEPTH 2 The DEPTH 2 parameter adjusts the amount of modulation of the Voice 2 signal. A lower depth setting will produce a more subtle detune effect, while a higher setting will produce a more extreme detuning of Voice 2.
  • Page 32 The DELAY function is available in all presets. Delay is a reproduction of the input signal, occurring at a prescribed time (usually expressed in milliseconds) following the input signal. The Voodu Valve™ provides two discrete delays (Delay 1 and Delay 2), each of which has its own parameters to deter- mine its particular characteristics.
  • Page 33 SOURCE 2 The SOURCE 2 parameter is used to select whether the Source 2 input will be the VOICE 2 output from the previous effect in the signal chain or the direct signal (DIR). DLY HF DAMP The DELAY HIGH FREQUENCY DAMPING parameter controls the amount of high frequency content in the delayed and regenerated signals.
  • Page 34 The REVERB function is available in all presets. Reverb is a multitude of echos spaced so close together that, to the human ear, seem as a single continuous sound. These echos gradually decrease in intensity until they are ultimately absorbed by the boundaries and obstacles within a room. As the sound waves from the sound source strike the boundaries of a room, a portion of the energy is reflected away from the obstacle while another portion is absorbed into it—thereby causing both the continuance of sound as well as the decaying or “dying out”...
