High Quality Audio Performance
The Sure Electronics AA-JA31181 1x 100 Watt Class D Audio Amplifier Board with Audio DSP - JAB3-100 delivers high quality sound without drawing a lot power. The JAB series amplier boards support Parallel Bridge Tied Load mode, under which two outputs are connected together as one channel. Under PBTL (mono) mode, either of the two inputs can work as the input connector. If audio signal is transmitted to both of the two inputs, the outputs are mixed. Connect the positive and negative output together for best eciency
Compatible with JAB1/ 2
JAB1 and JAB2 provide a stereo solution for portable Bluetooth speakers with MPPT battery charging. More than the headphone amplier, JAB3 also provides a exible DSP solution. This means, when working with JAB1/2 main boards, it is a complete 4.0 (BTL), 2.1 and 0.2 (PBTL) audio system with control interfaces and signal processing. The application ranges from active louderspeaker concepts (digital 3 way 3 unit, 2 way 2 unit crossover, bass enhancement, etc.) and realize the transformation from 2.0 to 2.1 (when used with JAB2). With four potentiometers, customers can get the default function and adjust the volume of audio input, gain, cut-o frequency of bass and treble.
DSP Integration
With integrated debug port for Sigima Studio, customers can pre-program with Sure Electronics ICP1, ICP2 or the original Analog USBi to get more functions which includes equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc. The on board fully programmable 28-/56-bit audio DSP ADAU1701 from Analog device is competent in various signal processing applications. This process can compensate for real-world limitations of speakers, ampliers, and listening environments, providing dramatic improvements in perceived audio quality. Most process is done in full 56-bit, double precision mode, resulting in very good low level signal performance. Two - ADCs and four - DACs integrated in this DSP provide a 98.5 dB analog input to analog output dynamic. Each ADC has a THD + N of -83 dB, and each DAC has a THD + N of -90 dB. The popular applications are active louderspeaker, public address system and active subwoofer, including stereo high pass lter and mixed low pass lter, also named with powered speaker controller.
Extremely low standby power
The Sure Electronics JAB3-100 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).
