1 Audio Input Port (JST PH 5-CKT): This port is used for connecting external audio sources via a 5-circuit JST PH connector. It
supports line-level audio input from devices such as CD players, computers, or other audio
sources. 2 Audio Input Port (3.5mm Audio Jack):
A standard 3.5mm audio jack allows for easy connection to portable devices like smart-
phones, tablets, or MP3 players. This port is convenient for quick and straightforward audio
input. 3 External Battery Supply Port (JST PH 4-CKT):
This port is designed for connecting an external battery pack using a 4-circuit JST PH connec-
tor. It allows the amplifier to be powered by a battery, making it suitable for portable or off-grid
applications. It can be connected to Lithium Battery Charging, Balance, and Protection Board
series from WONDOM, for example, to ensure safe and efficient battery management. 4 Power Input Port (Micro-Fit 2x1 CKT):
The main power supply connects to this port via a Micro-Fit 2x1 circuit connector. It provides
the necessary power to operate the amplifier, accepting a DC input voltage range of 12V to
24V. This wide voltage range allows for flexible power supply options, from smaller portable
batteries to larger power adapters. 5 Control Port (JST PH 4-CKT):
This 4-circuit JST PH connector is used for various control functions, such as enabling or
disabling the amplifier, muting the audio, or other user-defined control signals. 6 Speaker Output Port (Micro-Fit 2x3 CKT):
This port connects to the speakers using a custom cable with bullet connectors. The port
includes pins labeled "GND" and "MODE." By default, the JAB2+ operates in mono mode,
providing a single 100W output. To switch to stereo mode, outputting 2 x 50W, you must short
the "GND" and "MODE" pins. This setup provides flexibility in configuring the amplifier for
different speaker setups. 7 Channel Selection Switch:
This switch allows you to select the desired audio output channel. You can choose between
Left, Right, or Mix (both channels combined). This feature is useful for tailoring the audio
output to specific speaker configurations or listening preferences. 8 Gain Selection Switch:
The gain selection switch provides two options for setting the amplifier's gain: 20dB or 26dB.
This allows you to adjust the amplifier's output level to match the sensitivity of your speakers
or to achieve the desired volume level in your listening environment.

Caution & Warning
Power Supply Compatibility · Ensure the power supply voltage and current ratings match
the specifications of the JAB2+ amplifier. Using an incorrect power supply can damage the amplifier. It is recommended to use an adapter with a 12V to 24V output and a 3A or higher current rating. Do not use an adapter with more than 24V, or connect it to a truck, bus, or lorry battery system. These battery systems may have voltages higher than 24V and can float up to 29V, which will cause permanent damage to the amplifier. · Do not connect speakers with an impedance lower than recommended. Overloading the amplifier can lead to damage or reduced performance.

Note: This block diagram is for the Motherboard (AIPO2X50 audio amplifier) and the MAT-BM83 Bluetooth module. Please note, the MAT-BM83 can also be attached to other amplifier boards. The TPA3116 IC on the AIPO2X50 audio amplifier board is used as an example. The channel selection switch only functions in mono configuration mode, allowing selection of A (Mono Left), B (Mono Right), and C (Mix). When 'GND' is shorted to 'MODE' on the speaker output, the channel selection becomes non-functional, and the motherboard (AIPO2X50) switches to stereo mode.
