Troubleshooting
Precautions for daily use
- The connection between MX3s and the speaker must be correct. L+ to the red jack(+ in) of the left speaker, L- to the blackjack (- in) of the left speaker. Connection to the right channel is the same. Please ensure that the step is correct before proceeding to the next step. Mx3sis an amplifier with BTL output, the L- and R- jacks are separate, they are not connected to the ground or at the same point. So if you make a mistake at this step, maybe it will cause serious damage to Mx3s. The warranty is void when the user’s error connection leads to damage.
- Whether you need to connect or disconnect a cable, please turn off MX3s first.
- To cut the power of the AC adapter, please turn off MX3s first, then pull out the power cable or cut the power of the adapter.
- You must not keep the amplifier in a hot, humid environment or drop it.
- Opening the case instantly voids the warranty!
- Use the TOPPING AC adapter only.
- Topping accepts no liability for any loss or damage arising directly or indirectly from the failure of MX3s.
- For improvement purposes, specifications are subject to changes without prior notice.
