Troubleshooting And Handling
Have Something To Say To You
Hello, Dear Customers!
The Internal Structure Is Complicated, And a Variety Of Vital Parts Are Matched With Each
Other. So It Takes a Certain Running-In Period To Reach The Ideal State Designed By The
Engineer. During This Period, You Can Let The Equipment Work Continuously For a Period Of
Time, Or You Can Accumulate The Equipment To Reach a Burn-In Time.In This Way, Can
Effectively Improve The Delicacy Of The Sound, Become Mellow, Smooth And Elastic, And The
Dynamics Are More Powerful. The Overall Sense Of Longitudinal Depth Is Also Improved. At
The Same Time, The Speaker's Performance Can Be Adjusted During Process.
The Appearance Of The Body Is Made Of Aluminum Alloy Metal Shell, Which Has Good
Thermal Conductivity And Durability; The Surface Is Treated With Anodized Frosting Process,
And The Texture Is Delicate And Round. High-Density Integrated Pcb Circuit Design, 100%
Circuit Detection Without Breakpoints; 2 Times Better Than The Industry Standard For High-
Conductivity Copper Paving Materials; Minimize External Interference With The Shortest And
Efficient Wiring Method,Reasonable Design Layout, And Achieve High Fidelity Purpose.
① Can't Turn On
Please Fully Contact The Power Supply Or The Ac Input Port And Plug It Tightly. Check Or
Select Other Power Sockets Or Power Strips Of The Wall Mains.
② There Is No Sound From Rca
Straightly Look At The Machine Signal To Select The Gear, Whether The Selection Is Correct.
③ Only One Channel Has Sound
Whether There Are The Same Problems When Switching Between The Two Input Methods, If
So; Po Uses 1 Speaker, And Tests The Left And Right Channels In Turn. No; Please Check The
Input Signal And Signal Line.
④ The Power Amplifier Bluetooth Cannot Be Searched
1. Turn Off The Power Amplifier For About One Minute,And Then Turn It On Again To Connect
It Again.
2. Bluetooth Is Paired, When Mobile Phone A Is Connected To The Power Amplifier, Mobile
Phone B Can No Longer Find Amplifier. At This Situation, Turn Off The Bluetooth Of Mobile
Phone, And Mobile Phone B Can Search And Connect To The Power Amplifier.
⑤ There Is Abnormal Noise Inside The Power Amplifier
The Power Amplifier Uses a Relay To Switch Between Wired And Wireless Signals. When The
Bluetooth Connection Is Paused, It Will Drive The Relay To Make a Click. This Is a Normal
Phenomenon
