Anleitung Zusammenfassung
Contact the guitar’s manufacturer to identify the microphone associated with each Image. Volume For the cleanest noise-free sound, set Volume as high as possible without causing your amp or mixer to distort. Blend Use the Blend slider to set the balance between the pickup and the Image. 10 Tone Controls & Play/Edit Switch The Play/Edit switch lets you EQ the pickup and Image(s) independently. Pickup EQ Move the Play/Edit switch to Play and adjust the Bass, Mid and Treble controls. Switch to Edit and the preamp retains the pickup EQ settings, disengages the pickup tone controls and enables Image EQ . Return to Play and the preamp holds the pickup EQ settings until the Bass, Mid or Treble controls are moved (regardless of the current position of the controls). Programmable Image EQ To EQ an Image, move the Play/Edit switch to Edit. The “#” LED fl ashes to indicate Edit mode. Move the Blend slider to Aura, select an Image and adjust the tone controls. You can program EQ for each of the six Images: simply select another Image and adjust the controls. Switch to Play and the preamp retains the Image EQ settings, disengages the Image tone controls and enables pickup EQ. Go back to Edit and the preamp holds the Image EQ settings until the Bass, Mid or Treble controls are moved (regardless of the current position of the controls). 11 Phase Switches Phase (global) Use the Phase switch to improve bass response at low volume and suppress feedback at high volume. Push the Phase switch in and out and leave it in the position most pleasing to your ear. If feedback occurs, push the switch again. Relative Phase (pickup phase) To change the character of your blended sound, you may wish to change the phase of the pickup relative to the Image. There is no “best” position for Relative Phase and where you set it is a matter of personal taste. 1. Center Blend slider & switch to Edit. The “#” LED fl ashes to indicate Edit mode. 2. Push the Tuner button to toggle the relative pickup phase. = default. 3. To exit Relative Phase, move the Play/Edit switch to Play. You can program different Relative Phase settings for each of the six Images. Select a different Image and repeat above procedure. 12 Anti-Feedback Use this search-and-destroy Anti-Feedback fi lter in addition to the Phase switch. 1. Move Anti-Feedback switch left to On position and push the Measure button once. The tuner display will animate to indicate it is searching for feedback. 2. Turn up Volume, then either dampen the strings while tapping the body or play the troublesome note until the feedback begins. The fi lter will automatically identify and eliminate the feedback. The circuit will hold this offending frequency in memory until you push the Measure button again. Battery Replacement Pull the small tab at the top of the Onboard Aura toward you. The body of the preamp will swing out, revealing the battery compartment. Observe the polarity marks on the battery compartment and install a fresh 9V battery. We recommend a lithium battery for extended battery life. 13 Input Trim and VU Meter Adjust this set-and-forget control to accommodate the dynamics of your playing style. When you set Input Trim to the optimum level, you can play strongly without distortion and play quietly without hiss. To Set the Input Trim: • Unplug the guitar and pull the small tab at the top of the Onboard Aura toward you. Locate the small circular potentiometer on the right side of the preamp. • To turn on the VU meter, move the Edit/Play switch to Play and plug in the guitar while holding the Measure button for two seconds. Release the Measure button when a “U” is shown in the tuner display. The pitch LEDs (two arrows and a circle) will now display the input level. • Play the instrument strongly and watch the LED display. Use a small fl at-head screwdriver to raise or lower the trim control so all three LEDs fl ash occasionally with hard strumming. • To exit the VU meter, push the Tuner button. 14 Trim 15 Restore Factory Defaults 1. Unplug the guitar, move the tone controls to the center detent position. 2. Move the Edit/Play switch to Play. 3. Hold the Measure button, plug in the guitar and press the Tuner button within two seconds. 4. When the tuner display fl ashes an “F,” release the buttons. The factory reset is complete when the “F” stops fl ashing and the unit returns to normal operation. Defaults: • EQ for all six Images reverts to fl at. • Relative Phase settings return to default state. • Anti-Feedback frequency is reset to 100Hz. 16 Electrical Specifi cations Digital Signal Path: A/D, D/A conversion: Signal Processing: Typical in-use current consumption @ 9VDC: Typical 9V lithium battery life: Typical 9V alkaline battery life: Nominal output impedance: Recommended load impedance: Input Trim gain range: Maximum output level (onset of clipping): Baseline noise: Dynamic Range: Bass control: Midrange control: Treble control: Anti-Feedback: cut depth: All specifi cations subject to change ...
