AUDIOPHONICS XDA019 Stereo Amplifier Module 2x100W

The amplification moduleXDA019is based on the use of a pair of high-power transistorsTDA7294developed by the Swiss firm ST MicroElectronics.

It is capable of delivering a continuous power of 2 x 100W,andup to 180W peak under a load of 4Ω with a rate of maximum distortion of 10%on the 20Hz and 20KHz audible range.

Equipped with a very high thermal stability, the XDA019 protection system sophisticated against surges, and a function "Mute"to avoid switching noises when switching on / off.

The filtering is ensured by 2 electrolytic capacitors 50V Ruby mounted in parallel to totalize 20000uF.

There is also evidence of Silver plated double layer integrated circuit aprotection circuitUPC1237NEC, and oneDual Operational Amplifier KA5532 welded to the card.

Specifications :

  • Continuous Power:100W / 8Ω (THD 10% - 20Hz-> 20KHz) +/- 38V
  • 100W / 4Ω (THD 10% - 20Hz-> 20KHz) +/- 29V
  • Total Harmonic Distortion Rate: 0.1%
  • Recommended Power Supply Voltages:
    Under 4Ω: ± 20-30V (for example, transformer 160VA 2x24V )
                             Under 8Ω: ± 26-40V (for example, transformer 160VA 2x30V )
  • PCB dimensions: 120 x 100 x 60 mm (L x W x H)
  • Compulsory heatsink not included with this module
  • Weight: 180g

Bonjour!
C'est un très bon module ou j'ai réalisé un ampli 4 canaux pour alimenter des satellites fais maisons avec un petit boomer Célestion et tweeter Eminence, le son est clair et précis, même à fort niveau. Seul petit problème c'est la fixation du module sur le radiateur. Merci Audiophonics pour le conditionnement.

Bonjour,
Attention au dimensions annoncées du pcb 120x88x45mm
Les dimensions réelles sont 120x100x45mm.
Il ne s'intègre pas dans mon boitier, je ne peux donc rien dire, pour l'instant, sur son fonctionnement.
