The Audiophonics TPA-M50 is a compact amplifier with a low price but very good sound performance. The TPA-M50 is based on an amplification chip TI TPA3116D2 capable of delivering 50W of power under 8Ω, while benefiting from a Class D architecture ensuring a high efficiency of 90%. This energy reserve will allow the amplifier to accompany many speaker models or a subwoofer. Its high quality design allows it to provide low distortion, low noise and good dynamics for accurate and lively reproduction.

In addition, the amplifier also acts as a summing device, thanks to the use of a NE5532P AOP and capacitor tracking. This allows the TPA-M50 to receive a stereo signal to mix the two channels and finally output in mono, without losing the left or right channel. This function is particularly useful if the TPA-M50 is used alone and with a single speaker.
