Components Overview
Pads and Cymbals
- REMO Mesh Heads: The snare and tom pads feature REMO mesh heads, providing a realistic feel and rebound. These heads are highly durable and designed for extensive use.
- Dual-Triggering Technology: The 10" snare and 8" tom pads utilize dual-triggering technology, allowing for distinct sounds from the head and rim. This enhances the expressive capabilities of the kit.
- Velocity Sensitivity: All pads and cymbals are velocity-sensitive, meaning the sound's volume and timbre change based on how hard you strike them, mimicking an acoustic drum set.
- Cymbals:
- Hi-Hat (12"): Dual-zone with choke capability.
- Crash Cymbals (2 x 12"): Dual-zone with choke capability.
- Ride Cymbal (14"): Three-zone with choke capability, allowing for bell, bow, and edge sounds.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from module. | Power not connected; volume too low; headphones/output cables not connected properly. | Ensure power adapter is connected and unit is on. Check master volume and headphone/output connections. |
| Pad/Cymbal not triggering. | Cable loose or damaged; pad sensitivity too low; incorrect instrument assigned. | Check cable connection to both pad and module. Adjust pad sensitivity in module settings. Verify correct instrument is assigned to the pad. |
| Unwanted double triggers. | Pad sensitivity too high; pad rebound causing multiple triggers. | Reduce pad sensitivity in the module settings. Ensure mesh head tension is appropriate. |
| Module freezes or behaves erratically. | Temporary software glitch. | Power off the module, wait a few seconds, then power it back on. If the issue persists, perform a factory reset (refer to the full manual for instructions). |
