Wireless Pairing Issues
REACTOR Control won't pair wirelessly
Wireless pairing must be initiated manually every time both devices are powered on — they do not auto-reconnect.
To pair:
- Power on both REACTOR Control and the REACTOR amp
- Press and hold the Pair button on the back of the REACTOR amp
- Both the Bluetooth and Wireless LEDs on the amp should start flashing — pairing begins
- Once paired, the LEDs on REACTOR Control turn solid — you can now use the footswitches
If pairing still fails:
- Confirm Bluetooth is enabled on your REACTOR (Settings → Bluetooth → On)
- Make sure REACTOR Control is within range (up to 17m / 55ft line-of-sight)
- Reduce wireless interference (move away from Wi-Fi routers and other Bluetooth devices)
- Charge REACTOR Control if the battery is low
- If nothing works, use the included 1/4" TRS wired connection as an alternative
REACTOR amp won't enter wireless pairing mode (Bluetooth + Wireless LEDs don't flash)
When a cable is connected to the REACTOR CONTROL port on the back of the amp, the amp auto-selects wired mode and blocks wireless pairing. Long-pressing the Pair button will have no effect until the cable is removed.
Fix:
- Unplug any cable from the REACTOR CONTROL port on the back of the REACTOR amp.
- Long-press the Pair button on the back of the amp again.
- Both the Bluetooth and Wireless LEDs should now start flashing — wireless pairing has begun.
REACTOR Control fails to pair after factory reset
After factory reset:
- Power off both REACTOR amp and REACTOR Control
- Power on REACTOR amp first, wait for it to fully boot
- Power on REACTOR Control
- Press and hold the Pair button on the back of the REACTOR amp — both the Bluetooth and Wireless LEDs should start flashing
- Wait for the LEDs on REACTOR Control to turn solid, indicating successful pairing
If pairing still fails:
- Charge REACTOR Control fully before retrying
- Update firmware on both REACTOR and REACTOR Control
- Try wired connection as an alternative
Wired Connection Issues
Wired connection not working
Check these:
- Use the included 1/4" TRS cable (3 meters)
- Connect to the REACTOR CONTROL jack on the REACTOR amp rear panel
- Make sure the cable is fully inserted at both ends
- Try a different TRS cable if available
Note: When connected via cable, REACTOR Control will prioritize the wired connection for the lowest latency.
Connection Stability
REACTOR Control keeps disconnecting
For wireless connection:
- Charge REACTOR Control fully (check LED indicator)
- Move closer to REACTOR amp — stay within 17m / 55ft
- Reduce wireless interference (move away from WiFi routers, other Bluetooth devices)
For wired connection:
- Check cable connections at both ends
- Try a different TRS cable
- Inspect cable for damage
If disconnections persist:
- Factory reset REACTOR Control and re-pair
REACTOR Control Not Responding
REACTOR Control is unresponsive
Quick checks:
- Check battery level — charge if low (LED shows red when low)
- Try pressing and holding the power button for 3 seconds
- Connect via USB-C to charge (you can use it while charging)
If still unresponsive:
- Perform a Factory Reset
- If factory reset doesn't work, contact support
Footswitches not triggering
Check these:
- Confirm REACTOR Control is connected (check connection LED)
- Make sure you're in the correct mode (Preset Mode or Effect Mode)
- Check if the function is assigned in the REACTOR App
Try:
- Power cycle REACTOR Control
- Re-pair with REACTOR amp
