WONDOM AA-AB41136 aptX Bluetooth 4.0 Audio Receiver Board Wireless Stereo DIY

This receiver could work well together with the Bluetooth adapter in the laptop or desktop computer, or mobile phones with Bluetooth audio streaming output support. It supports Bluetooth V4.0 + EDR and supports A2DP protocol, has a 3.5mm audio jack built-in for audio output. You can also use the 4-pin connector on the rear panel to get another audio output channel. The distance between this unit and the Bluetooth transmitter could be up to 10 meters, but note that it can vary greatly depending on the environment.

It can be connected with a Bluetooth adapter or a mobile phone with Bluetooth. The output terminal can be connected with a headphone or a power amplifier to transmit wirelessly. The maximum transmission distance is 10m.

High quality resistance and capacity components, including X7R ceramic capacitors and lower ESR electrolytic capacitors, are used to obtain the perfect timber, finally achieving a high S / N ratio, low THD + N, wide frequency response range , etc.

The Bluetooth audio receiver card contains the anti-inversion function. Parts of analog and digital audio are powered by 2 independent chips, which mainly eradicate RF and digital signal interference with audio.

Modulo Bluetooth

Features:

• A perfect Bluetooth audio receiver card

• Supports the APT-X decoding algorithm, which extends the range of Bluetooth frequencies from 16-20 KHz.

• Single-end audio signal output

• LED status indicator

• External power supply and signal output connector

• Anti-inversion function

• Different wiring methods facilitate the connection: 3.5 mm socket (default), RCA socket (optional)

• Compression ratio: 4: 1 (APT-X Live is 8: 1, SBC is 3: 1 to 6: 1)

• Word depth: 16-bit, 24-bit audio support

• Codec delay: sampling frequency 48kHZ <2ms; (SBC is 2.5 ms + buffer time, the average time of 170 ms + buffer time)

• Dynamic range (volume): 16 bit> 92 dB, 24 bit> 120 dB (SBC 16 bit from 70 dB to 75 dB)

• Data rate: 352kbps (SBC is 320kbps)

• Frequency response range: 20Hz-22kHz (SBC is 20Hz-17kHz)

• Sampling frequency up to 48 kHz (8,16,24,32,44,1,48 kHz)

• Good fault tolerance (BER <1: 10,000 for perfect reproduction)

• The synchronization scheme of the complete AUTOSYNC codec and the synchronization time <3ms

• Low energy consumption

Benefits:

• APT-X support, with low latency, good fault tolerance, high quality, wide frequency response range, etc.

• Excellent heat dissipation eliminates the need for an additional heat sink.

• Degree of audio output distortion of 0.5% or less

• Independent analogue and digital power supply, minimize interference.

Applications:
• Desktop wireless music receiver

• Wireless audio source for amplifiers

• Wireless headphone driver (the HP amplifier had to be used with some headphones)
