3.1 Controls
- Doubling Knob: Selects the type of vocal doubling effect. Options include Tight, Loose, and Octave Up/Down. Rotate the knob to choose your desired doubling style.
- Reverb Knob: Adjusts the reverb type and intensity. Options include Room, Club, and Hall. The 'Off' position disables reverb.
- Correction Knob: Controls the amount of automatic pitch correction applied to your vocals, from 'Off' to '100' (maximum correction). Start with a lower setting and adjust to taste to avoid an unnatural sound.
- Tone Button: Engages the adaptive tone feature, which applies automatic EQ, compression, de-essing, and gating for a polished vocal sound. The LED illuminates when active.
3.2 Footswitch Functionality
The single footswitch on the DUPLICATOR controls multiple functions:
- Single Click: Toggles the Doubling effect on or off.
- Long Press: Toggles the Reverb effect on or off.
This allows for dynamic control over your vocal effects during a performance.
4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your DUPLICATOR.
4.1 Cleaning
Wipe the unit with a soft, dry cloth. Avoid using abrasive cleaners or solvents, which can damage the finish and internal components.
4.2 Battery Replacement
If using batteries, replace them when the power indicator light dims or the unit behaves erratically. Always replace all four AA batteries simultaneously with new ones.
4.3 Storage
When not in use for extended periods, disconnect the power adapter and remove the batteries. Store the unit in a cool, dry place away from direct sunlight and extreme temperatures.
5. Troubleshooting
If you encounter issues with your DUPLICATOR, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Incorrect connections, no power, output level too low. | Check all XLR cable connections. Ensure power is supplied (batteries or adapter). Verify the mixer/PA input is active and volume is up. |
| Noisy signal | Faulty cables, ground loop, low battery. | Try different cables. Ensure all equipment is properly grounded. Replace batteries or use a power adapter. |
| Effects not engaging | Footswitch mode, knob set to 'Off'. | Ensure the Doubling and Reverb knobs are not set to 'Off'. Check footswitch operation (single click for doubling, long press for reverb). |
| Pitch correction sounds unnatural | Correction knob set too high. | Reduce the 'Correction' knob setting. |
If the problem persists after attempting these solutions, contact TC Helicon customer support.
