Q&A

Bluetooth can’t work.Please make sure you have followed the steps below to debug?

First, you need to check whether the bluetooth mode is turned on (when it is turned on, the screen displays BLUE). If it is not turned on, press the “BT” button or the “MODE” button to switch to the bluetooth mode.Turn on the bluetooth input device, such as a mobile phone, turn on the bluetooth function to search for the model name of the power amplifier (MAMP5), click to connect, and hear a beep (provided that the speaker has been connected), indicating that the connection is successful.Note: Regarding the Bluetooth transmitter without a screen, you only need to turn on the Bluetooth transmitter, get close to the power amplifier, and then wait for the connection

If you find that the Bluetooth connection is unstable, you can try the following steps to solve it?

Make sure there are no obstacles (especially metals) blocking the signal; Turn off the power amplifier, disconnect and clear the connection of the Bluetooth transmitting device, and try to reconnect; Note: If this happens at the beginning, please consult us to tell us about more details such as video, mobile phone model, etc..

No, connecting two at the same time will cause the audio stream to be disrupted. It can only be disconnected and then connected to other devices.

How to connect to a bluetooth speaker?

The Bluetooth speaker is a Bluetooth receiver, which is the same as the Bluetooth function of the power amplifier, and the Bluetooth speaker already has a small power amplifier, which may cause burn-in after being amplified by other power amplifiers.

The Bluetooth of the power amplifier is not enough, how to connect the external Bluetooth receiver

First, find the input port of the power amplifier to receive the signal, such as the 3.5mm port of AUX or the RCA port of AUDIO INPUTThen, connect the output end of the Bluetooth receiver to the input port of the power amplifier (the port does not correspond, please use the corresponding port interface converter)
