Sure Electronics AA-JA32473 2 x 30 Watt Class D Audio Amplifier Board
The Sure Electronics AA-JA32473 2 x 30 Watt Class D Audio Amplifier Board with Audio DSP - JAB3-30 is an amplifier board easily built in to any project, speaker build or other DIY project in need of a small amplifier board. HighlightsADAU1707 Audio DSP IntegratedPBTL ConfigurableFully Compatiable with JAB1 and JAB2USBi or WONDOM In-Circuit ProgrammerDebug Port for Sigma Studio through original Connections:  High Quality Audio PerformanceThe Sure Electronics AA-JA32473 2 x 30 Watt Class D Audio Amplifier Board with Audio DSP - JAB3-30 delivers high quality sound without drawing a lot power. The JAB series ampliï¬er 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 efficiency Compatible with JAB1/ 2JAB1 and JAB2 provide a stereo solution for portable Bluetooth speakers with MPPT battery charging. More than the headphone ampliï¬er, JAB3 also provides a flexible 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-off frequency of bass and treble. DSP IntegrationWith 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, ampliï¬ers, 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 Σ-Δ ADCs and four Σ-Δ 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 ï¬lter and mixed low pass ï¬lter, also named with powered speaker controller, demonstrated on this board as follows.  Extremely low standby powerThe Sure Electronics JAB3-30 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).    Applications  Package includes1 x Sure Electronics JAB3-30 2 x 30 Watt Class D Audio Amplifier Board with Audio DSP1 x power cable1 x 4-conductor speaker cable1 x 5mm jack cable Show more Show lessSure Electronics AA-AB41122 | 100V | 30A | 35000uF
Add stable power to your amplifier boards and amp projects using this rectifier board that's built with 35,000 microfarads of power-buffering, ripple-reducing capacitance. Four high performance, ultra-fast ST Electronics' STTH1602 diodes are combined with ceramic capacitors for minimum harmonics. HighlightsConverts up to 100 VAC to symmetrical positive and negative DC voltageRobust terminal connections, 1/2" standoffs, and multi-layer PCBSupports power converting for up to 2,000 watt devicesSixteen 2,200 uF capacitors for power buffering Product details Sure Electronics AA-AB41122 100V 30A 35000uF Rectifier Board for Amplifiers Built with 35,000 microfarads of power-buffering and ripple-reducing capacitance, this rectifier board converts AC input voltage into separate positive DC and negative DC voltage outputs. It features robust terminal connections, 1/2'' standoffs and multi-play PCB, perfect for supplying power to amplifier boards requiring large symmetrical power supplies. The robust heatsink on board provides a drastic reduction for the system temperature and ease of cooling. Four high performance, ultra-fast ST Electronics' STTH1602 diodes are combined with ceramic capacitors for minimum harmonics. AC power is applied to the input (positive on the AC1 X terminal, negative on the AC2 X terminal, with center taps connected to the inside AC1 and AC2 terminals if used), with positive DC output on the VDD/POS terminal and symmetrical negative DC output on the VEE/NEG terminal. An LED indicator shows the voltage output for each channel. Note: To calculate voltage output, multiply the secondaries voltage by 1.414 (the square root of 2). For instance, if you were to connect a 110 VAC primary input to two 75 VAC secondary output transformer to this rectifier board, the output would +106 VDC and -106 VDC. Specifications:• Repetitive peak reverse voltage (VRRM): 200V• Supply voltage: 0 to 100 VAC• RMS forward current: 20A• Forward voltage drop: 1.1V• For use with devices up to 2,000 watts• Dimensions: 6" L x 4.5" W x 2.5" H (152.4 x 114.3 x 63.5 mm) Warning: Working with high voltages is extremely dangerous and should only be done with the utmost precaution and the right amount of knowledge about the matter! These components should be treated carefully. Failing to do so voids your warranty and puts yourself in danger.Show more Show lessSure Electronics AA-JA31211 1 x 60 Watt Class D Audio Amplifier Board
