Package list:
1 * Power Amplifier Board
1 * Cable
Selection Criteria:
1. Power requirements: voltage voltage 3.7V-5V, voltage can not be higher than 5V; current 1.5A-2A; (specially reminded that if using 3.7V , please ensure that and discharge can 1.5A, some has voltage but current is not Please use with caution if it is stable or does not meet the requirements; otherwise it will always restart or the sound quality is not good, such as broken sound/distortion.
Speaker requirements:
(Satellite) left and right channel sub-box speaker: select 4 ohm ()/5W*2 full-range speaker (special reminder if you use 3.7V , please ensure that and discharge can 1.5A, some has voltage but current is unstable Please use caution if you can't meet the requirements; please choose 4 ohms () / 3W * 2 for the speakers.
2. 3P socket OUT audio output: If you need to connect other power amplifiers can be connected from here (intermediate audio ground, left and right are L and R respectively.
connection: The mobile phone starts detection from the setup menu, so that the mobile phone is detected by the device, and then goes to the menu - search for the device or the paired device. After searching (YMX-868BT) "Touch Pairing", it also hears "Connected successfully or prompts" to complete the pairing;
Note: It is not the smartphone ( system) to enter the password -0000; the product device name YMX-868BT.
Pay Attention:
1) Red 2P BAT is connected to the power supply positive 3.7V to 5V+, GND is connected to the negative pole; white 2P is connected from the bottom to the upper L-O-/L-O+, and the white 2P is R-O-/R-O+.
2) Working voltage 3.7V, or regulated power supply 4.5-5V, current (600-700MA when connected to a speaker; 1.5-2A for two speakers). Lithium-powered speaker with 4 ohms 3W+3W, voltage regulator Power 5V speaker with 4 ohms 5W+5W. If the current is not enough, there will be a or instability, the motherboard will always restart or the sound quality is not good / broken / distortion and other bad phenomena (if you have this problem, please check your power); The voltage should not be higher than 5V, otherwise the main chip and the amplifier IC and related components will be damaged. Please pay attention.
3) Audio output: 3P block OUT audio output can be modified for external power amplifier, the middle is audio ground, left and right are L and R respectively.
