Topping MX3S Amplificateur Class D Infineon Amplificateur Casque DAC Bluetooth aptX Adaptive 2x50W 4Ω 24bit 192kHz Argent

An efficient Class D amplifier

The amplifier section of the MX3S uses an Infineon Merus Class D chip allowing it to deliver a power of 2x50W under 4Ω with a high efficiency higher than 90%. It also offers a characteristic restitution marked by a beautiful clarity and precision. The MX3S also offers a two-level gain control allowing it to adapt to your listening system.

Bluetooth

In addition to its complete connectivity, the Topping MX3S provides a Bluetooth receiver, allowing a remote broadcast of your music, from a smartphone or a tablet for example. The chip used supports the aptX, aptX HD and aptX Adaptive transmission codecs, promoting quality wireless sound reproduction.

Subwoofer output

With its RCA format subwoofer output, the MX3S can be used to set up a 2.1 audio system. The use of a subwoofer allows you to achieve deep and punchy bass.

Signal detection

The digital inputs of the Topping MX3S have an automatic detection of the input signal. This allows the unit to be turned on automatically when it receives an audio signal and to be turned off if no valid signal is received for one minute.

Built-in equalizer

In order to adapt to your listening and your audio system, the Topping MX3S benefits from a built-in equalizer. It allows you to adjust the bass and treble levels over a range of -10dB to +10dB.

My travel partner
Works fine and this is my travel partner, used with a pair of Ino Audio piXM.
The only issue I have is the low level of amplifying when running blue tooth from my Android. When serving by USB-C from Android one gets much more power out and far better sound as well.
