High Quality Audio Performance
The Sure Electronics AA-JA32171 2 x 50 Watt 4 Ohm Class D Audio Amplifier with Bluetooth 4.0 APT-X - JAB2-50 delivers high quality sound without drawing a lot power. This is due to the highly efficient Texas Instruments TPA3116 Class-D amplifier chip. The TI TPA3116 operates at 90% efficiency, which becomes a major advantage when powering from batteries as it prolongs the playtime of a single charge. Its ultra-low distortion and pop-free performance make this hi-fi amplifier board an integral asset in any quality audio build.
Extremely low standby power
The Sure Electronics JAB2-50 will remain powered up to 7 days in standby mode even while Bluetooth is enabled. This standby time is approximately 4x longer than the competition due to the use of a high efficiency DC/DC converter which minimizes power consumption thanks to the employment of a micro controller as the PMU (Power Management Unit).
Integrated Bluetooth
The Sure Electronics JAB2-50 Amplifier Board offers a built-in Bluetooth 4.0 module with aptX which offers both high quality sound and low power consumption. It enables easy pairing with any mobile device or tablet for convenient access to audio. It is also CE and FCC ready for certification purposes.
Multiple Power Paths
The Sure Electronics JAB2-50 features numerous power options for creative, wireless sound projects. This flexibility eliminates limitations often caused by most other amp boards. Therefore, your design can be cord restricted or truly portable.
