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.

Subwoofer output

The A30 has a suwboofer output on RCA connector. It is thus possible to use the amplifier to power a 2.1 system and enjoy a rich reproduction with deep bass.

Bluetooth

Convenient, the Loxjie A30 allows you to receive your audio files remotely, in Bluetooth, directly from your smartphone. The Bluetooth 5.0 standard combined with the aptX protocol allows for a stable and high quality transmission.

EQ Mode

To suit your listening style and your audio system, the A30 offers no less than 7 preset equalizers as well as a customizable equalizer. The bass and treble levels can be adjusted in 1dB steps from -10dB to +10dB.

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.

Robust and elegant

The components of the A30 are housed in an elegant and robust aluminum case, offering excellent rigidity that also eliminates case vibration, while limiting the impact of electromagnetic interference on the circuits. The screen is protected by a highly transparent tempered glass pane.

Précis & Musical
Fonctionne très facilement en Bluetooth (mais juste en 48 kHz...) en délivrant une puissance modeste mais plutôt correcte pour 20-25 M2.
Ne chauffe pas du tout et sans aucun bruit parasite.
Pas encore testé en Hi-Res, via USB ou fibre Optique mais déjà étonnée par la qualité musicale restituée.

Ordered this little unit because I needed a new amplifier for speaker measurements. The ASR review showed perfect load independent linearity, and that was exactly what I needed for the purpose. In short, it all works as expected, the connections give me all the possibilities to input the measurement signals. And by the way, a short sound test via spdif convinced me so far. For a second sound system, or perhaps as a travel companion, the device is a great option. Small criticism: The device tilts a bit, because one foot is sunk deeper than the others. Since this is easy to fix and does not affect the function, I still give all stars as a rating.

Excellent !
Vraiment ravi de mon ampli. J'avais, juste avant un FX-AUDIO, (D802C) qui faisait le taf musicalement mais qui avait deux soucis, la connectique : pas de sortie Subwoofer et l'écran qui a mal vieilli et qui était illisible, à part dans le noir total... Pour mon caisson je le branchait donc en parallèle sur mes enceintes mais bon...
Là on a produit vraiment au top, je le préfère 100 fois ! Déjà la finition, l'écran magnifique à côté de mon D802C. Couleurs personnalisable, dimmer automatique ou non, sortie Sub, et SURTOUT plus progessif niveau volume. Dans mon cas je suis branché en USB sur mon PC (donc en système 2.1 caisson Magnat et enceintes maison) Avec le FX-AUDIO, avant, même volume à 1 c'était trop fort une fois tout le monde couché, mon PC étant sur le palier devant les chambres... C'était tout ou rien, à moins de me brancher en analogique mais cela n'aurait aucun intérêt. Là je trouve un volume progressif parfait sur ce LOXJIE. Franchement, pour 30€ c'est le jour et la nuit.

Perspicace !
Eh oui, Perspicace, c'est le mot qui décrira au mieux ce petit ampli de chez Loxjie que je ne peux que conseiller. 2 semaines d'essai et vraiment pas déçu de mon achat. Pour ceux qui veulent se créer un petit 2.0 / 2.1, pour le prix, foncez ! Me concernant il est couplé à une paire d' Klipsch RB-81 II et le rendu sonore est vraiment très très bon, j'ai joué un peu avec le treble pour régler et le tour est joué. Bref, rien à redire pour le moment, à voir dans le temps !
