Sure Electronics - AA-JA33286

DESCRIPTION

AA-JA33286 is a real All-in One solution for many customers application. 4 channels audio amplifier board integrated with Bluetooth 5.0 (supporting aptX HD) and ADAU1701 DSP. Output power is 100W at 6ohm for channel. This amplifier board has 3 different inputs: Bluetooth 5.0, AUX Line, I2S.
ADAU1701 DSP is on board and allows different of custom configuration. Customer can adjust volume, gain, frequency and EQ setting to customize own audio output. ADAU1701 DSP can be programmed  with SigmaStudio, APP control and PC UI control after connection with WONDOM ICP5 or higher version(s).
In addition to 4.0 mode (4 x 100W), AA-JA33286 supports configuration as 2.1 mode (2 x 100W + 1 x 200W), 2.0 / 0.2 mode (2 x 200W), applicable for various audio projects.

AA-JA33286 can cascade with another JAB5 to build audio 8.0 or other systems. Wireless audio input, integrated ADAU1701 DSP, multiple output modes and high quality audio performance make AA-JA33286 perfectly suitable for Bluetooth speakers, home audio, garden audio, digital crossover and DIY audio applications.
A DC10V-39V power supply is required.

Bluetooth 5.0

AA-JA33286 has a Bluetooth 5.0 module for audio input, which supports various audio formats as APT-X, APT-X HD, APT-X LL, SBC & AAC and high receive sensitivity with RF power up to 9dBm and -90dBm. There is a built-in antenna equipped on this board. So you can directly pair AA-JA33286 with the device to play music. An external antenna port is also provided on the board to ensure the stable connection and high audio performance in such applications that AA-Ja33286 is installed into a speaker or a cabinet.
Bluetooth pairing cancellation function is integrated on AA-JA33286. You can disconnect with Bluetooth by one simple press, without worry about which Bluetooth is paired. Standby function is also available on AA-JA33286. Ports for External LED indicators are offered to show the status of Bluetooth and signal, so you can have an overview of the running condition of AA-JA33286.

ADAU1701 DSP

AA-JA33286 is also integrated with high performance ADAU1701 DSP chip for audio signal processing. Four ports for external potentiometers are mounted on PCB. You can use the external potentiometers to control the gain and frequency even if AA-JA33286 is installed into a speaker cabinet. Please refer to the datasheet or connection guide for the detailed functions of potentiometers.
After connection with WONDOM ICP5 (DB-DP11226) programmer interface or higher versions, you can write a program with SigmaStudio, or get real-time remote control of your audio systems via APP or PC User Interface, through which, you can adjust gain, volume, high/low-pass filter, EQ and other parameters. 

Input configuration

In addition to Bluetooth input, AA-JA33286 supports 3.5mm line input and I2S input. Signals from the three input methods will be mixed before being transmitted to the amplification circuit. You can get the 3.5mm AUX-IN cable and the PH-6Pos cable in the Functional cables kit (AA-JA11117).

Output configuration

AA-JA33286 is a very flexible amplifier with differents Output Configuration. Each two channels can be configured as one channel with double power. Therefore, it can be used as 4.0 mode (4 x 100W), 2.1 mode (2 x 100W + 1 x 200W) and 2.0 / 0.2 mode (2 x 200W), suitable for diverse audio systems. In order to provide customers with easy operation, there is automatic cables insertion identification on PCB, based on which, the switching among the output modes is so convenient that you just need to plug in the cables as required. The functions of the four external potentiometers would change accordingly. Please note, if you want to use AA-JA33286 as 0.2 mode, frequency adjustment in the PC UI is essential besides hardware settings. 0.2 mode is not supported when using hardware control (Potentiometers).

Cascade configuration

Besides speaker output, AA-JA33286 supports I2S signal output, which can be transmitted into another I2S amplifier board. You can cascade one AA-JA33286 with another AA-JA33286 to build an 8 x 100W system or other audio systems you want through the I2S input and output port. There is a switch on the board for setting the AA-JA33286 as master mode or slave mode in above condition. Fully considering the easy control and audio performance of the built audio system, Sure Electronics prepares a synchronization port on JAB5 to ensure the control logic of the two boards are consistent. As for the details, please refer to the datasheet.

Signal Level Sensor System

AA-JA33286 has a signal level sensor system for lower power consumption and longer playback time. It will continuously monitor the input signal and there is a preset signal voltage threshold. When there is no signal (voltage is lower than the threshold) detected for 5min, the amplifier module will enter into standby mode automatically, in which condition, it will consume lower power. When there is signal detected, it will run immediately without any miss of the audio.
