LOXJIE A30 Class D Amplifier Infineon MA12070 Bluetooth 5.0 2x50W 4 Ohm

Infineon Merus MA12070 amplifier

The amplification circuit is based on an Infineon Merus MA12070 chip. This allows to develop a consequent power of 2x50W under 4Ω, while ensuring a very low distortion, an excellent efficiency and a complete protection system.

The chip's power management algorithm automatically adjusts switching frequency and modulation to limit power loss and EMI interference.

Complete connection system

The A30 has full connectivity to integrate with the vast majority of audio systems. The A30 has stereo RCA, Coaxial, Optical and Micro USB inputs. This last input supports sample rates up to PCM 32bit 384kHz. On the output side, there are speaker terminals on the back and a 6.35mm headphone output on the front.

Coaxial input and RCA input share the same interface and therefore cannot be used at the same time.

Quality components

The entire Loxjie A30 benefits from a careful design, based on components known for their audio quality. While the A30 features the very good Infineon MA12070 amplifier chip, the A30 also includes a 24-bit ESS ES9023 DAC with an integrated 2Vrms AOP. The latter uses HyperStream architecture and Time Domain Jitter Eliminator technology to significantly reduce jitter and provide a dynamic range of 112dB.

Volume and tone control is entrusted to an NJW1194 chip, ensuring low distortion and low noise with a ladder resistor system.

A great amp, unbeatable for the price
Extremely clean, crisp and analytical sound. No discernible noise, even if you hold your ear directly to the tweeter. This also speaks in favour of the high quality of the power supply unit. Its treble is a little too strong for me personally, but I easily reduced it using the tone control. Operation is very simple and the workmanship is very high quality. Thank you, Audiophonics, for the fast and safe delivery.
