FX-Audio Amplificateur 2x TPA3116D2

This Class D amplifier module incorporates two TPA3116D2 amplifier chips providing a power of 2x50W + 100W for the subwoofer output. It also includes 4 potentiometers that allow you to adjust the gain and tone.


The amplification is ensured by two Texas Instrument TPA3116D2 chips, providing a power of 2x50W under 4 Ohms for your speakers and 100W for your subwoofer under 2 Ohms, while enjoying the high efficiency of about 90% of the design in Class D. This also ensures a reduction of AM interference as well as protection against over-voltage, undervoltage, excessive temperatures, short-circuit and DC current detection.

A complete system

With its dedicated TPA3116D2 amplifier chip, the module incorporates a 100W subwoofer output allowing you to complete your system, to enjoy bass more present or deep, supporting frequencies between 80 and 500Hz. With its 4 rotary encoders you can enjoy a hardware adjustment of gain and tone.

Un bon module d'amplifaction
Utilisé au sein d'un pincab en deux exemplaires, ce petit module d'amplification est parfaitement adapté.
Les réglages sont précis et agréables, la puissance parfaitement suffisante pour l'utilisation envisagée.
Attention toutefois au choix de l'alimentation... La fiche précise du 10/25V DC 3A, j'ai du changer celle envisagée car cette dernière n'était pas suffisante pour le faire fonctionner (la carte s'allume mais pas de son).
Une alimentation de 24V 4A est donc indispensable.
Ce produit offre un excellent rapport qualité prix, je le recommande pour les budgets serrés.

Super Rapport Qualité/Prix
Je me sers de cette carte pour amplifier des enceintes venant d'un kit de home cinéma (2x50w et 1x100w). Alimenté par une alim de pc portable de 19V en 3,2A, cela fonctionne parfaitement. Pour les petits budgets et avec un peux de récupération, on obtiens un kit 2.1 d'assez bonne qualité.
Envoie soigné .
