AUDIOPHONICS XDA019 - Amplifier module TDA7294 2x100W

AUDIOPHONICS XDA019 Stereo Amplifier Module 2x100W

The amplification moduleXDA019is based on the use of a pair of high-power transistors TDA7294 developed 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 circuit UPC1237 NEC, and oneDual Operational Amplifier KA5532 welded to the card.
