  • Page 6 PRESET control This control scrolls through the successive presets. CONFIG button/led The status of this button determines whether the Voodu Valve™ will display either the preset number and title or the configuration of the currently displayed preset. The configuration display indi- cates the effects that the displayed preset executes and, in most cases, the order in which they are executed.
  • Page 7 STORE button/led This button is used to store values into the Voodu Valve™ memory when altered. See "Storing Changed Preset Parameters" in Chapter 8 for more information on this procedure.
  • Page 8 INPUT LEVEL control This control adjusts the unit’s gain to match the signal level at the input of the Voodu Valve™. Use the INPUT LEVEL meter to determine the setting of this control. INPUT jack This standard, unbalanced mono 1/4" jack is used to provide input...
  • Page 9 In addition, this jack also allows for the connection of stereo headphones (600 impedance or greater). (R) UNBALANCED OUTPUT jack This 1/4" unbalanced RTS jack provides the right unbalanced output of the Voodu Valve™ for use with a guitar amplifier or rack system setup.
  • Page 10 7-pin MIDI cable which connects from the Rocktron MIDI foot controller to the MIDI IN jack on the rear panel of the Voodu Valve™. This eliminates the need to find an AC outlet near where the footpedal would be placed during a performance, or the need to run an extension cord out to the footswitch.
  • Page 11 MIDI THRU/OUT jack This standard 5-pin DIN connector can be connected to the MIDI IN jack of another device via a standard MIDI cable. There are limitations to the number of devices that can be chained (or series connected) in this fashion. Note: Inherently in MIDI there is a limit to the number of devices which can be chained together (connected in series).

  • Page 16 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 17 The PARAMETER SELECT control will allow you to access these Mixer parameters: VOLUME The VOLUME parameter determines the overall signal level of the current preset. LEFT OUT LVL The LEFT OUT LEVEL parameter allows you alter the level of the left channel output of the current preset independent of the right channel.
  • Page 18 VARIAC ADJUST The VARIAC ADJUST parameter adjusts the level at which the preamp stage in the Voodu Valve™ begins to distort. A Variac is a voltage- attenuating device that plugs into an AC wall outlet and adjusts the voltage level to any device which is plugged into it. For years, many guitarists have plugged their amplifier heads into a Variac and reduced the voltage coming into the amplifier from the AC wall outlet.
  • Page 19 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. GAIN The GAIN parameter determines the gain value in the distortion stage. TUBE The TUBE parameter allows you to select between four different tube distortion types - Hard Clip, Soft Clip, Class A, Class B.
  • Page 20 The PARAMETER SELECT control will allow you to access these Hush® parameters: HUSHI/O The HUSH I/O parameter simply determines whether the HUSH® circuit is active for the current preset. HUSH THRESH The HUSH THRESHOLD parameter determines the level at which downward expansion begins.
  • Page 21 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 boost the low frequencies from -15dB to +6dB prior to the distortion stage. This EQ section is a shelving-type. LF FREQ The pre-LF (low frequency) FREQUENCY parameter allows you to select a frequency band with an upper frequency between 63Hz and...
  • Page 22 The PARAMETER SELECT control will allow you to access these POST EQ parameters: BASS LVL The post-BASS LEVEL parameter allows you to cut or boost the low frequencies by 15dB after the distortion stage. BASS FREQ The post-BASS FREQUENCY parameter allows you to select a center frequency between 63Hz and 500Hz to be cut or boosted by the post- BASS LEVEL parameter.
  • Page 23 The PARAMETER SELECT control will allow you to access these COMPRESSOR parameters: COMPRESSOR I/O The COMPRESSOR IN/OUT parameter determines whether the compressor is active for the current preset. COMP THRESH The COMPRESSOR THRESHOLD parameter determines the input level (in dB) at which compression will begin. Lower settings of this parameter will result in more compression.
  • Page 24 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. SPKR TYPE The SPEAKER TYPE parameter determines the type of speaker to be simulated.
  • Page 25 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. WAH FREQ The WAH FREQUENCY parameter allows you to manually sweep the frequency range of the wah-wah via the PARAMETER ADJUST control.
  • Page 26 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. DEPTH 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.
  • Page 27 The PARAMETER SELECT control will allow you to access these FLANGER parameters: FLANGER I/O The FLANGER I/O parameter determines whether the Flanger is active or bypassed for the current preset. LEVEL 1 The LEVEL 1 parameter determines the volume of Voice 1 relative to Voice 2.
  • Page 28 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. LOCATION The LOCATION parameter determines whether the Tremolo is located Pre-Reverb or Post-Reverb. Most vintage amplifiers configured the Tremolo (or vibrato) Post-Reverb.
  • Page 29 The PAN parameter allows you to pan the shifted signal to the left or right channel. PITCH The PITCH parameter selects what harmony note the Voodu Valve™ will produce based on the input note. The value displayed for this parameter represents the number of cents that the signal will be shifted (adjustable in 20-cent increments).
  • Page 30 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 31 The PARAMETER SELECT control will allow you to access these CHORUS parameters: CHORUS I/O The CHORUS I/O parameter determines whether the Chorus is active or bypassed for the current preset. LEVEL 1 The LEVEL 1 parameter determines the volume of Voice 1 in relation to Voice 2.
  • Page 32 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 33 The PARAMETER SELECT control will allow you to access these DELAY parameters: DELAY The DELAY parameter determines whether the Delay is active or muted for the current preset. MUTE TYPE The MUTE TYPE parameter allows for muting the delay at its input (PRE), its output (POST) or BOTH.
  • Page 34 Delay 1 signal will begin. The DELAY TIME can be adjusted via the ADJUST control, MIDI controller changes or via the Tap Delay feature (see "Operating the Voodu Valve" for detailed descriptions of each).
  • Page 35 The PARAMETER SELECT control will allow you to access these REVERB parameters: REV INPUT The REVERB INPUT parameter determines whether the input to the Reverb section is ACTIVE (passing a signal) or MUTED (will not pass a signal). MIX DIR/DLY The MIX DIRECT/DELAY parameter is used to define the ratio of direct signal to delayed signal to be input to the reverb section.
