Topping MX3S is a real army knife for audio, acting as an amplifier and headphone amplifier with an integrated AKM AK4377 DAC and Bluetooth receiver. Ideal for a small or medium listening room, it can provide dynamic, accurate and reliable reproduction.
Efficient Class D Amplifier
The MX3S amplifier uses an Infineon Merus Class D chip, allowing it to deliver 2x50W into 4Ω with a high efficiency of over 90%. It also offers a characteristic restitution, distinguished by excellent clarity and precision. The MX3S also offers a two-stage gain control, allowing you to adapt to your listening system.
Bluetooth
In addition to full connectivity, the Topping MX3S is equipped with a Bluetooth receiver, allowing you to stream music remotely, for example from a smartphone or tablet. The chip used supports the aptX, aptX HD and aptX Adaptive transmission codecs, facilitating high-quality wireless audio playback.

Subwoofer output
Thanks to the presence of an RCA subwoofer output, the MX3S can be used to organize a 2.1 audio system. Using a subwoofer allows you to achieve deep and assertive bass.
Signal detection
The Topping MX3S digital inputs feature automatic input signal detection. This allows the unit to automatically turn on when it receives an audio signal and turn off if no signal is received for one minute.
Built-in equalizer
To adapt to your preferences and audio system, Topping MX3S is equipped with a built-in equalizer. It allows you to adjust the bass and treble levels in the range from -10 dB to +10 dB.
