FAQ - SP10 Wireless Stomp Pedal
Q1. Can I use the microphone I already have?
The SP10 transmitter uses a Sennheiser-compatible 3.5mm connector and supports Mic / Line signals including high-impedance inputs. Most common microphones and instrument pickups can be used with the right adapter cable.
Official Adapter Cables
| Part Code | Adapter Type | Compatible With |
|---|---|---|
| CW03A | 3.5mm to 3.5mm | SonoFlex microphone (2-wire mode) |
| CW03B | 3.5mm to 3.5mm | SonoFlex microphone (3-wire mode only) |
| CW052 | 3.5mm to Microdot female | DPA microphones |
| CW06 | 3.5mm to 6.3mm TS | 6.3mm TS instrument pickups |
| CW07 | 3.5mm to XLR Female | Dynamic XLR microphones (no phantom power) |
| CW041B | 3.5mm to TA4F | Mipro microphones |

Q2. How do I connect the SP10 — wired and wireless?
SP10 is a 1-to-1 system — one transmitter pairs with one receiver. It supports both wireless and wired operation. The receiver has an automatic input-priority system: when multiple inputs are connected at the same time, only the highest-priority input will be active.
Input Priority (highest to lowest)
- SonoFlex wired input — via dedicated CW03B cable
- 6.3mm wired input
- Wireless reception (paired with transmitter)
Receiver Connectors & How to Use Them
- SonoFlex input (3.5mm, upper-right): Connect SonoFlex directly to the receiver using CW03B. Highest priority — disables all other inputs when connected.
- 6.3mm wired input (right side): For direct connection to instrument pickups. Use a standard 6.3mm instrument cable.
- Wireless: Pair the receiver with the SP10 transmitter. Ensure all wired inputs are disconnected — otherwise the priority system will override wireless audio.
SP10 receiver input ports: SonoFlex 3.5mm (upper-right), 6.3mm instrument input (right), and wireless pairing.

Q3. What power options does the SP10 receiver support?
The SP10 receiver does not have a built-in battery. It supports two power options:
- 9V DC power supply (center-negative)
- USB-C 5V — portable power banks are supported
If You're Getting Noise
- Use a well-isolated power source — an audio-grade power supply or a power bank works best
- Noise is usually caused by power quality or grounding issues — try switching the power source before troubleshooting elsewhere
Q4. SP10 vs ISOLO vs EverSync IEM — which should I choose?
They solve different problems. Start by asking: what do you want to make wireless?
- EverSync IEM (5.8GHz): Sends audio wirelessly to your earphones — a wireless in-ear monitoring system
- EverSync SP10 (2.4GHz): Sends your microphone or pickup signal wirelessly to a speaker or mixer — a wireless performance system
- ISOLO: Best for solo performers who want direct, on-board control over tone, volume, and mixing
- SP10: Best for users who want to go wireless with an existing microphone or pickup, using an external mixing system

Q5. How do I adjust FX Blend — and why can't I do it on the receiver?
FX Blend is adjusted in different places depending on whether you're using the SP10 wirelessly or wired:
- Wireless mode: Adjust FX Blend on the transmitter — the receiver has no effect
- Wired mode: Adjust FX Blend on the receiver — the transmitter has no effect
Q6. What should I do if the receiver and transmitter fail to pair?
Factory reset both units, then re-pair them.
Receiver Factory Reset
- Press and hold Audio and Radio simultaneously for about 5 seconds
- The reset is complete when a confirmation message appears on screen
Transmitter Factory Reset
- Keep the transmitter powered on
- Press and hold PAIR and MUTE simultaneously for about 3 seconds
- The LED will indicate reset status — once complete, re-pair both units
Q7. How do I switch instruments — or use wired mode as a backup?
SP10 is a 1-to-1 system — one receiver pairs with one transmitter only. Up to 8 SP10 systems can operate simultaneously in the same space, but each is independent.
Switching Instruments Mid-Performance
- Mute the transmitter first to avoid pop noise
- Swap to the appropriate adapter cable for the next instrument
- Unmute the transmitter and continue playing
Using Wired Mode as a Backup
If the transmitter runs out of battery, switch to wired without stopping the performance:
- Use a standard 6.3mm instrument cable — connect the pickup output directly to the receiver's 6.3mm input
- To connect SonoFlex directly to the receiver, use CW03B (not CW03A — it has a locking ring that cannot fit the receiver's jack)
- Do not use CW06 in reverse — it is designed for the transmitter side only and may cause signal instability
