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.
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.
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.
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.
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.
