More info

The amplification module APD87 is based on 3 high-performance circuits LM3886 developed by National SemiConductor.

Working in Class AB, and capable of 50W continuous power under a load of 8Ω, this trio of transistors can reach 400W peak, with a coherent harmonic distortion rate of only 0.1%.

With a thermal and electrical stability, the 4145 is equipped with a double protection system sophisticated surge protection (proprietary technology Spike™) and undervoltages, the latter occurring when the power supply drops below 12V.
The filtering of the transistors uses 2 electrolytic capacitors of 63V / 470μF. An MKP capacitor of 2,2uF / 400VDClocated at the input to suppress the DC component of the signal.

WARNING :This product requires the use of a passive radiator of appropriate size.
Some components may vary according to delivery.


  • Continuous Power: 50W / 3Ω +/- 35V
  • 100W / 4Ω +/- 28V
  • Signal to Noise Ratio: ≥ 92dB
  • Input Impedance: 47kohm
  • Total Harmonic Distortion Rate: 0.1% (20Hz-> 20KHz)
  • Supply Voltage Recommended: ± 28-35V DC (Transformer between 20V and 25V AC)
  • Total Dimensions: 135 x 62 x 42mm (L x W x H)
  • Weight: 120g

Supreme sound
This amplifier is capable of devivering very clean sound, although the capacitor in photo is diferent in size and color from the real one, also the size dont match the description.
The real size is 120mm x 51mm x 25 mm.

Quel son !
Utilisé avec deux modules en symétrique , le son est super et la puissance est bien présente. Dans mon cas je les utilises pour alimenter un haut-parleur de grave de 30cm.

monté en double mono ,avec de très gros dissipateurs,et une alimentation "maison",ce module s'avère d'une grande musicalité, d'une dynamique ,confortable et d'une neutralité indéniable
