[. . . ] TUBE DRIVEN PROGRAMMABLE GUITAR PREAMP 24-BIT DSP USER'S MANUAL May be covered by one or more of the following: U. S. Patents #4538297, 4647876, 4696044, 4745309, 4881047, 4893099, 5124657, 5263091, 5268527, 5319713, 5333201, 5402498, 5493617 and 5638452. Foreign patents pending. Your VooDu Valve Online has been tested and complies with the following Standards and Directives as set forth by the European Union: Council Directive(s): Standard(s): 89/336/EEC Electromagnetic Compatibility EN55022, EN50082-1 This means that this product has been designed to meet stringent guidelines on how much RF energy it can emit, and that it should be immune from other sources of interference when properly used. Improper use of this equipment could result in increased RF emissions, which may or may not interfere with other electronic products. [. . . ] The post-TREBLE FREQUENCY parameter allows you to select a high-band center frequency between 1KHz and 8KHz to be cut or boosted via the post-TREBLE LEVEL parameter. The post-TREBLE BANDWIDTH parameter determines (in octaves) the width of the selected high band. The post-PRESENCE LEVEL parameter allows you to cut or boost another high-band frequency by 15dB after the distortion stage. The post-PRESENCE FREQUENCY parameter allows you to select a high-band center frequency between 2KHz and 8KHz to be cut or boosted via the post-PRESENCE LEVEL parameter. The post-PRESENCE BANDWIDTH parameter determines (in octaves) the width of the selected high band.

This function allows you to compress the signal prior to the distortion stage. Compression is often used to maintain an even level when using clean tones, and also to increase sustain when using distorted tones. 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. 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. The COMPRESSOR ATTACK parameter determines the speed (in milliseconds) in which the compressor will reach its maximum compression level after the input signal has exceeded the threshold level (set by the COMPRESSOR THRESHOLD parameter). 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. [. . . ] Reinitialization of the controller assignments is necessary when setting up the Voodu Valve to operate in remote mode with a Rocktron All AccessTM footswitch. To reinitialize only the controller assignments, enter a code number of "221" at Step 3 on the opposite page. 96 Selecting a Power On Preset The Voodu Valve allows you to store a Power On preset which will always be recalled when the unit is turned on. 2 1 3 Step 1 Turn the PRESET control to the preset number you wish to be recalled each time the unit is turned on. PRESS RECALL FOR Ö 34 PRESET TITLE Step 2 Recall the selected preset by pressing the RECALL button. 34 PRESET TITLE Step 3 Press the STORE button while viewing the preset number and title to save it as the Power On preset. PWR ON PR STORED 97 Using the Voodu Valve with a Rocktron All AccessTM in REMOTE mode A Rocktron All AccessTM MIDI footswitch can act as a dedicated remote control for the Voodu Valve--allowing direct access to specific Voodu Valve features and parameters from the footswitch at any time. Step 1 To use an All AccessTM footswitch as a dedicated remote, connect the MIDI OUT of the All Access to the REMOTE jack of the Voodu Valve using a 7-pin MIDI cable, as shown below. To set up the Voodu Valve for remote operation, do the following: Step 2 Reinitialize the controller assignments as shown earlier in this section under the heading "Restoring the Voodu Valve Controller Assignments". This will match up the Voodu Valve's controller assignments to the All Access. A code of "221" must be entered to initialize only the controller information. ALL RESTORE 98 221 Step 3 Turn the FUNCTION SELECT control clockwise to "REMOTE CONTROL". REMOTE CONTROL Step 4 Turn the PARAMETER SELECT control one step clockwise to display "REMOTE". REMOTE Step 5 OFF Turn the PARAMETER ADJUST control to select "ON". REMOTE Step 6 ON If the Voodu Valve titles are to be displayed on the All Access, turn the PARAMETER SELECT control to "TITLE XFER". TITLE XFER Step 7 OFF Turn the PARAMETER ADJUST control to "ON" to enable title transfers from the Voodu Valve to the All Access display. TITLE XFER ON To set up the All Access for remote operation, perform these steps from the All Access SETUP program: (See the All Access user's manual for detailed information on editing the All Access) Step 8 Step 9 Step 10 Set the Operating Mode to "REMOTE".
