[. . . ] PROGRAMMABLE 24-BIT DSP GUITAR PREAMP User's Manual 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, 5333201, 5402498 and 5493617. Foreign patents pending. Your Chameleon 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-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. 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 19 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 Chameleon 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 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 20 WAH-WAH Function The WAH-WAH function is available only in configurations which display "WAH" in the configuration title. The Chameleon has an internal wah-wah which allows for an expression pedal to be used as a wah-wah pedal through continuous 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 MateTM) and set the controller's MIDI channel to correspond with the Chameleon's receiving MIDI channel. Then set the pedal's control number on the MIDI Mate to match the Wah Frequency parameter's control number on the Chameleon. This control number is set on the Chameleon in the "CONTROLLER ASSIG" function. (See "Controller Assignments" 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 WAH-WAH parameter IN allows you to use the wah-wah as a fixed wah. WAH FREQ 21 PHASER Function The PHASER function is available only in configurations displaying "PHAS" in the configuration title. [. . . ] The preset currently recalled will be the preset most recently restored into the current location. Restoring the Chameleon controller assignments: The controller assignments for the Chameleon can also be reinitialized without affecting presets and other stored information. Reinitialization of the controller assignments is necessary when setting up the Chameleon to operate in remote mode with a Rocktron All Access® footswitch. To reinitialize only the controller assignments, enter a code number of "244" at Step 3 above. 93 Selecting a Power on Preset: The Chameleon 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 34 PRESET TITLE Step 3 Recall the selected preset by pressing the RECALL button. Press the STORE button while viewing the preset number and title to save it as the Power On preset. PWR ON PR STORED 94 Using the Chameleon with a Rocktron All Access® in REMOTE mode A Rocktron All Access MIDI footswitch can act as a dedicated remote control for the Chameleon - allowing direct access to specific Chameleon features and parameters from the footswitch at any time. Step 1 To use an All Access footswitch as a dedicated remote, connect the MIDI OUT of the All Access to the REMOTE jack of the Chameleon using a 7-pin MIDI cable. To set up the Chameleon for remote operations do the following: Step 2 Reinitialize the controller assignments as shown earlier in this section under the heading "Restoring the Chameleon Controller Assignments".
