The XH-A901 preamplification module is a preamp circuit that uses the operational amplifier NE5532 (two integrated on the board). This board is designed to improve the sound quality of audio systems by amplifying and adjusting the tone of the signal.
The treble and bass controls allow the user to adjust the tone of the signal to obtain an optimized sound. Also, the XH-A901 preamp board has a high signal-to-noise ratio and low distortion, which means it will pick up sound accurately and faithfully.
Includes connectors for audio input, power and audio signal output. The board allows the adjustment of the total volume, Treble, Middle and Bass. The output from the pre-amplifier is stereo, with two channels, Left and Right.
The integrated NE5532 are inserted in sockets, which makes them easy to change if this is necessary.

Am luat si eu acest modul si la fel ca si la Catalin, bazaie ca naiba.Mentionez ca l-am folosit in urmatoarele configuratii: 1. Amplificator in clasa AB alimentat cu traf cu priza mediana 2x30v si infasurare simpla pe 12v 2. Acelasi amplficator mentionat anterior, dar de aceasta data am alimentat corectorul de ton din sursa de laborator setata pe cca 12v 3. Amplificator tot in clasa AB dar de putere mai mica ce necesita 12v DC pe care l-am alimentat tot din sursa de laborator alaturi de corectorul de ton. Am alimentat si separat corectorul de ton de la un alt alimentator de 12v. 4. Amplificator in clasa D alimentat cu sursa in comutatie din aceea cu mai multe iesiri 24v, 12v si 5v. Ampliful l-am conectat la 24v si corectorul la 12v. In toate aceste cazuri mentionate corectorul de ton bazaie crescendo in functie de nivelul volumului. Nici macar la volum minim nu pot scapa de acel zgomot. Mentionez ca toate amplifurile enumerate au fost legate si fara acest corector de ton si functioneaza impecabil, fara nici un zgomot(mare parte din ele tot de aici sunt luate). Asa ca sigur voi face cerere de retur pt ca este clar ca este o eroare din fabrica
Bazaie pentru ca masa de semnal output e plutitoare deoarece nu ai alimentare diferentiala, pentru alimentari singulare recoamnd ceva unde operationalele sunt configurate inversor
am cumparat acest corector de ton .. dar nu sunt multumit de el ca are acel barait pe fundalul sonor si creste cind dai volumul la maxim .. am tot conectat surse de alimentare de la 12..14.19 si nimic .. pare ca este defect .. am sa comand altul sa vad daca este la fel .. daca este si acesta cu acelasi rezultat .. ma desabonez de la aceata pagina .
