The TPA3116 audio power amplifier chip shown in the figure has been upgraded to the TPA3118 chip.

The TPA3116 audio power amplifier chip shown in the figure has been upgraded to the TPA3118 chip.

      One of the standout features of the JAB4 is the inclusion of the ADAU1701 DSP.    This DSP allows for advanced audio programming using SigmaStudio software.    Additionally, the JAB4 supports control via mobile app and PC UI when connected to WONDOM ICP programmers.    This extensive control capability allows users to fine-tune various parameters such as volume, gain, frequency, and EQ settings to create a customized audio experience.

The JAB4 offers multiple output modes to suit different audio projects. It can be configured as a 4.0 mode with four channels delivering 30W each, a 2.1 mode with two channels delivering 30W each and an additional channel providing 60W, or a 2.0 / 0.2 mode with two channels delivering 60W each. for a wide range of applications, including portable Bluetooth speakers, home audio systems, garden audio setups, digital crossovers, and various DIY audio projects.

Furthermore, the JAB4 provides an I2S signal output, allowing you to transmit the audio signal to an I2S audio amplifier board for expanded functionality or multi-speaker setups.

   The can be configured in 4.0 mode (4x30W), 2.0/0.2 mode (2x60W) and 2.1 mode (2x30W+1x60W). Simply insert the corresponding speaker harness output mode to switch automatically.

Note that if you want to use the JAB4 as 0.2 mode, in addition to the hardware configuration of the speaker interface, you also need to set the frequency in the PCUI. JAB4 is not supported as a 0.2 output mode under hardware control (potentiometer) conditions.

This model is equipped with a small signal detection system to effectively reduce power consumption and improve efficiency. When the system does not detect an audio signal for a long time, the JAB4 enters standby mode. In this case, JAB4 will resume work as soon as an audio signal is detected.

Power amplifier preset signal threshold.

When the signal voltage is below the preset threshold for more than 5 minutes, the JAB4 automatically enters standby mode. When the input signal voltage exceeds the preset threshold, the power amplifier is triggered and enters the normal working mode. If you do not need the small signal detection function can be achieved by short circuiting the RST and +5V2 pins on the J4.

Note:

1.JAB4 speaker output channel 1 (J11) is defined as CH1; JAB4 speaker output channel 2 (J12) is defined as CH2. 2.POT1 and POT2 are used to adjust the CH1 output channel. POT1 adjusts the relative gain of CH1 based on the total gain. POT3 is used to adjust the CH2 output channel, and POT4 is used to adjust the total gain. When JAB4 is used in 2.1 mode, you can configure any output channel as a 0.1 low channel. The function of the potentiometer will change automatically. If you want to use JAB4 in 0.2 mode, you need to set the output mode and frequency in PCUI. In hardware control mode (potentiometer), JAB4 does not support configuration as 0.2 mode. 3.HPF refers to high-pass filter, and BPF refers to band-pass filter. When CH1 (CH2) is used as stereo output, POT2 (POT3) functions as a high-pass filter; when CH1 (CH2) is used as a single-channel output, POT2 (POT3) functions as a band-pass filter.
