Module MA12070

Balanced Stereo Amplifier 1.0 / 2.0 / 2.1 / 4.0 MA12070 160W @ 4 ohms




This amplifier module is based on an Infineon MA1270 Class D amplifier chip. It uses two power half-bridges with 4 MOSFETs where each transistor is driven by its own separate PWM signal. This highly efficient circuit offers remarkable performance while maintaining a very compact form-factor.

Capable of developing up to 2x80W at 4 Ohm in its stereo 2.0 mode, it is an ideal solution for your integrated amplifier / speakers & active monitors projects. Its multiple switching power supply circuit (3rd and 5th degree modulation) make it a very low energy consumption and formidable efficiency amplifier solution.

Very musical, its amplification circuit offers a signal / noise ratio superior to 110dB with an extremely low background noise (7.45µV), which makes it a solution of choice for your on-board High Fidelity projects.

From 1 to 4 channels

Extremely versatile, the module is able to work in 1.0 mode with a power of 160W at 4 ohm, in 2.0 mode (2x80W), in 2.1 mode (2x 40W + 80W) as well as in 4.0 mode (4x 40W).

Switching from one mode to another is done using a DIN type selector located directly on the PCB. All the connection possibilities as well as the different configurations can be found in this PDF document.

Heatsink & Spacers


The MA12070 module is read with its (large) radiator already mounted and fixed. The latter ensures excellent heat dissipation in addition to the integrated protections against overheating. This ensures ideal operating conditions for the Infineon chip

Likewise, 4 spacers and 4 screws are supplied & already mounted on the module. All there is to do to obtain a functional amplifier is to power the module and plug in your other modules / devices.

The connector below is reserved for factory settings. Do not use it.
