Description

DC3.7V-5V Stereo 5.0 Bluetooth 5W*2 Bluetooth Decoding Module with Power Amplifier Rechargeable Audio Amplifier Bt10w Speaker

Features:

This product uses 5.0 Bluetooth DC3.7V-5V power supply

The maximum power of secondary development processing can be configured to reach 10W (5W*2)

Micro wave power switch control

Stereo two-channel

External amplifiers can be retrofitted

Product parameters:

Power supply: DC voltage (3.7-5V), the current must be more than 1.5A-2A

USB is the charging input: when the lithium battery is plugged into the red power socket, it can be charged from here; the red light is on when charging, and the red light is off when fully charged

Left and right channel sub-box speakers: choose 4Ω/5W*2 full-frequency speakers (special reminder if you use 3.7V lithium battery, please ensure that the lithium battery discharge can reach 1.5A, some lithium batteries have voltage but the current is unstable or can not meet the requirements, please Use with caution; please use 4Ω/3W*2 for speakers)

Bluetooth connection: Turn on the phone's Bluetooth detection from the settings menu, so that the phone can be detected by the device, then go to the Bluetooth menu - search for devices or paired devices, after searching (YMX-868BT) "touch pairing" is also heard at the same time The sound of "connection is successful or prompt tone" completes the pairing;

Note: It is not a smart phone (Android system) to enter the password -0000; product Bluetooth device name YMX-868BT

Pay attention:

1. The red 2P seat BAT is connected to the positive power supply DC3.7V to 5V+, and the GND is connected to the negative electrode; the white 2P seat is connected to the speaker 1 from bottom to top, L-O-/L-O+, and the white 2P seat R-O-/R-O+ is connected to the speaker 2

2. Working voltage lithium battery 3.7V, or regulated power supply DC DC 4.5-5V, current (600-700MA when connecting one speaker; 1.5-2A when connecting two speakers. Lithium battery powered speaker with 4 ohms 3W+3W, stable voltage The power supply 5V speaker is equipped with 4 ohms 5W+5W. If the current is not enough, there will be skipping or Bluetooth instability, the motherboard keeps restarting, or the sound quality is not good/broken/distorted (if there is such a problem, please check your power supply); The voltage cannot be higher than 5V, otherwise it will damage the main chip, power amplifier IC and related components, please pay attention

3. Audio output: 3P seat OUT audio output can be used to modify an external power amplifier, the middle is the audio ground, and the left and right are L and R respectively
