Product Description:

Welcome Bluetooth audio receiver entry Ver4.0. The receiver can be used with a Bluetooth adapter laptop or desktop computer， or use a Bluetooth audio streaming output supports phones work well together. It supports Bluetooth V4.0 + EDR， and supports A2DP protocol， it has a built-in 3.5mm audio jack audio output. You can also use the rear panel 4PIN interface to obtain another audio output channel. The distance from the unit and Bluetooth transmitter can be up to 10 meters. Note， however， that it may be based on many different environments and different.

It can be connected with a Bluetooth adapter or mobile phone with Bluetooth. The output of the power amplifier can be used with headphones or to transmit a wireless connection. The maximum transmission distance of 10m.

High quality resistive and capacitive elements， including X7R ceramic capacitors and low ESR electrolytic capacitors， used to get the perfect timber， and ultimately achieve a high S / N ratio， low THD + N， wide frequency response range.

Bluetooth Audio Receiver board contains anti-reverse function. Analog and digital audio in part by two separate chips， mainly to eliminate interference with RF and digital signal power audio.
