2 Quick Installation

During the practical Jukebox / kiosk amplifier installation, up to several dozens of minutes will be spent on connection and debugging in the last step of assembly and test. The reasons behind potential problems lie in many aspects of operation, such as power pins reverse polarity, the correct multi-channel orders, volume adjustment of each channel, signal channel disconnection caused by the poor contact and so on. In order to solve problems mentioned above and improve the effective connection and pass rate of test, we take advantage of different forms of connectors for power connections, speaker connections, signal input connections and potentiometer connections. For example, 2CKT molex  Micro-Fit  vertical headers, 4CKT / 6CKT JST PH SMT top entry type headers are populated in JAB for easy recognizations. Furthermore, we also provide the matched extension cables for different connectors, which can be easily distinguished from each other by different cable colors. We spare no effects in improving the connection and debugging efficiency and saving the cost on installations and debugging.

4 Benefits:  

High Sound Quality

More than low power consumption, Sure Electronics provides very high sound quality at the same time. Everything is nothing without a high sound quality. We can get less than ±3dB frequency response at the AUX channel, which is same at the Bluetooth channel if APT-X is enabled. For most Sure Electronics audio amplifiers, we can get about 90dB or more SNR and 0.01% distortion when outputting 1Watt.PBTL (Mono) Mode ConfigurableThe JAB series amplifier 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. For PBTL mode configu-ration, 500 pieces MOQ will be requested. Customers must send a requirement  to us for confirmation before placing the order. Sure Electronics cannot be considered responsible for eventual damages caused to persons, things or data for customer’ misconfiguration of the PBTL mode.

Compatible with JAB1/ 2

JAB1 and JAB2 provide a stereo solution for portable Bluetooth speakers with MPPT battery charging.More than the headphone amplifier, 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 tansformation 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.     Customers can connect the JAB3 with JAB1/2 via the JST-PH-6PIN connectors on board. For more detailed connection information, please refer to the installation chapter.

Adaptive Power Supply Module for RV/Yacht Application

If your projects are powered by the battery system of the RV or Yacht, we could provide the adaptive power supply which always outputs DC 24V when the input voltage is not less than 10V and no more than 40V. And the power supply module is capable of delivering 100W continuously and 200W with the efficiency up to 85%, which is suitable for audio power amplifier application.* The power voltage range of JAB3 series is 12 - 24V, typical 19V. For any input voltage requirement, please feel free to contact with us.

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, amplifiers, 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 filter and mixed low pass filter, also named with powered speaker controller, demonstrated on this board as follows.

Aluminum bracket type L (Optional)

It is quite difficult to assemble the audio amplifier board in an enclosed space like most Kiosk and Jukebox applications. To improve the connection and measurement efficiency and save on installation costs, Sure Electronics offers an L-type aluminum bracket for the JAB series. The aluminum bracket supports the vertical and horizontal installation modes to meet different installation needs. With 4 M3 screw spacers and 2 pre-punched M3 mounting holes, the JAB series audio amplifier boards can be easily installed on the bracket.

STEEP 5 SET THE SWITCHES AND JUMPERS

 Stereo Headphone Amplifier Integration

The headphone amplifier delivers up to 125mW per channel into a 32ohm load and has low 0.02% THD+N. It uses capless Direct-drive architecture to produce a ground-referenced output from a single power supply, eliminating the need for large DC-blocking capacitors for output, and saving cost, board space, and component height. The gain is set internally (-2V/V or -1.5V/V), further reducing component count. 

Fully Protection, Robust Performance

The amplifier board series employs the TPA311x series from TI as the main chip. All of them are equipped with overcurrent and overtemperature protection, which is able to avoid permanent stress caused by improper operation.Besides built-in chip protection, ESD and spike protection components are used throughout input and output of the amplifier board to ensure its robustness and reliability. And all the available input and output pins are presented as molex headers which facilitate mating and prevent accidental mis-mating during assembly.

Extreme Low Standby Power

The JAB series could offer playback time up to 24 hours continuously, which was tested with Bluetooth connected and Jazz style songs  playing back continuously. The maximum output voltage on the speaker is 4V RMS and the duty is no less than 5%. Sure Electronics also offers a solution with the continuous playback time up to 60 hours, which is more than 2 days with only 2 hours quick charge. This version can only provide a 7.5Watts maximum output at 4ohm loads, but that is already enough for most applications.The standby time is calculated with Bluetooth always enabled, which means the Bluetooth can always be searched. Its 7-day-long standby time is not achieved by stopping the Bluetooth module. So comparing with competitive products, we can afford about 4 times more standby time with very high efficiency DC/DC converter and low power consumption micro controller as the PMU (Power Management Unit).The standard products you can order from this sheet are not the best performance ones we can provide. Sure Electronics can now proudly announce that we have solutions with more than 60 hours continuous playback time, and more than 10-day standby time. And it can provide extremely low distortion at the same time. Contact us right now for more details.

Extension Boards Optional

Sure Electronics has released one interface extension board to provide a simple panel mounting solution for customer’s applications. Interfaces on board include a 3.5mm AUX jack, 2CKT USB ports for charging, a switch button with LED power indicators.With the headers or a 10 pin cable, the interface extension board will be connected to the amplifier board and integrated to your system quickly. The Sure Electronics 3/ 4/ 5 cells in series 18650 Lithium-ion battery balance and protection extension board is especially designed for 3/ 4/ 5 cells 18650 type batteries in series. Customers can use solar panels for their applications. Just remember to use solar batteries with float (open) voltage with 16.5-21.5V, and use 20-100Watt panels for this applica-tion. For example, 3 Lithium-ion batteries in series output more than 12.6V when fully charged. Customer could also connect 2 pieces lithium battery balance and protection extension boards in parallel to get higher voltage. The 3/ 4/ 5 cells in series 18650 Lithium-ion battery balance and protection extension board is integrated with overvoltage and undervoltage protection circuits. It could balance differ-ent voltage among batteries. For more detailed information, please refer to product data sheet.
