Precautions for daily use

( i )

• The connection between MX5 and the speaker must be correct. L+ to the red jack ( + in) of the left speaker, L- to the black jack (- in) of the left speaker. Connection to the right channel is the same. Please ensure that step is correct before proceeding to the next step. MX5 is a amplifier with BTL output, the L- and R- jack are separate, they are not connected to the ground or a same point. So if you make a mistake at this step, maybe it will cause serious damage to MX5. Warranty is void when user’s error connection led to a damage.
• Whether you need to connect or disconnect a cable, please turn off PA3 first.
• To cut the power of AC adapter, please turn off PA3 first, then pull out the power cable or cut the power of adapter.
• You must not keep the amplifier in a hot, humid environment or drop it.
• Opening the case instantly voids the warranty!
• In case where liquid is spilled into the machine, turn off the power immediately and check the device inspected by a professional before further use.
• Use TOPPING AC adapter only.
• Maintain the volume so no distortion will have much better listening experience.
• Indoor use only.
