  • Page 7 The DISPLAY panel provides 16 characters consisting of 14 segments each. EFFECT BYPASS button/led When lit, the Pre and Post effects are bypassed and only the Compressor/Preamp signal is passed to the Chameleon outputs This button does not affect the condition of the Speaker Simulator. COMPARE button The COMPARE button may be used to compare an altered parameter value to its stored value.
  • Page 8 This will help you to guard against clipping the output of the mixer at the digital- to-analog converter. 15 INPUT LEVEL control This control adjusts the unit's gain to match the signal level at the input of the Chameleon. Use the INPUT LEVEL meter to determine the setting of this control. 16 INPUT jack This standard, unbalanced mono 1/4"...
  • Page 9 (L) UNBALANCED OUTPUT jack This 1/4" unbalanced RTS jack provides the left unbalanced output of the Chameleon for use with a guitar amplifier or rack system setup. In addition, this jack also allows for the connection of stereo headphones (600ohms impedance or greater).
  • Page 10 MIDI cable which connects from the Rocktron MIDI foot controller to the MIDI IN jack on the rear panel of the Chameleon. 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 12 Using the Chameleon direct into a mixing console...
  • Page 13 To see the configuration of each preset, press the CONFIG button on the front panel of the Chameleon - the LED above the CONFIG button will light and the display will show the configuration for the current preset. Turning the PRESET control will then scroll through each successive preset (displaying its configuration instead of its preset number and title).
  • Page 14 It is the setting of each of the parameters which determines the overall sound of each preset. The Chameleon is set up to allow you to first access each function (via the FUNC- TION SELECT control), then the parameter list for each function (via the PARAMETER SELECT control) and finally the adjustable value for each parameter (via the PARAM- ETER ADJUST control).
  • Page 15 - as the active guitar would require a higher Threshold level in all presets. MUTE The MUTE parameter allows you to mute the output of the Chameleon. This feature is ® especially useful when changing guitars during a live set. If a Rocktron All Access used in remote mode with the Chameleon, 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 VARIAC ADJUST parameter adjusts the level at which the preamp stage in the Chameleon 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 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: GAIN The GAIN parameter determines the gain value in the distortion stage.
  • Page 19 A/D converter. This ensures a quiet input signal to the preamp section. Because the preamp section of the Chameleon is digital, it is virtually noise-free (even in the high-gain mode). Therefore, a quiet input signal to the preamp will result in a quiet output signal.
  • 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 SELECT control 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 frequen-...
  • 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. 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...
  • 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. 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...
  • 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 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.
  • Page 24 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.
  • 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 IN/OUT parameter determines whether the Phaser is active for the current...
  • 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 I/O The TREMOLO IN/OUT parameter determines whether the Tremolo is active or by- passed for the current preset.
  • Page 28 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 Chameleon 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 29 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...
  • Page 30 The CHORUS function is available only in configurations displaying "CRS" in the configuration title. The Chorus effect in the Chameleon 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 Delay is a reproduction of the input signal, occurring at a prescribed time (usually expressed in milliseconds) following the input signal. The Chameleon provides two discrete delays (Delay 1 and Delay 2), each of which has its own parameters to determine its particular characteristics.
  • Page 32 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 Chameleon" for detailed descriptions of each). REGEN 1 The REGENERATION 1 parameter determines the number of times the Delay 1 signal will repeat itself.
  • Page 33 The REVERB function is available in all presets. Reverb is a multitude of echoes spaced so close together that, to the human ears seem as a single continuous sound. These echoes gradually decrease in intensity until they are ultimately absorbed by the boundaries and obstacles within a room.
