The TDA7498 module is a class D amplifier, with dual-BTL 100W+100W output, with single power supply, designed for home theater and active speaker applications.

Important : Using the amplifier with 4-ohm speakers may cause it to burn. If you still want to use 4 ohm speakers, use a voltage as low as possible and be careful of overheating the amplifier. If necessary, use active cooling by applying a fan to the radiator. Burning the module by using speakers with a value other than 8 ohms leads to the loss of the warranty.

Pentru boxe cu impedanta de 6 ohmi este bun?
Foarte bun
rating 5
Achiziționat pentru o sala de conferințe cu 8 boxe. Nu mă pricep la sunet ca să mă exprim cu privire la calitatea lui, dar, alimentat la 12v 1A, nu are deloc zgomot de fond, ceea ce mă interesa. Recomand!
multumit

Sunet plin cu inalte și bass suficiente încât sa nu ai nevoie de un corector de ton.
Surprinzator de bun

Este un amplificator foarte bun. Sunet corect, puternic, bas sustinut foarte bine, head room bun. Atentie la impedante si semnal de intrare. Unele cipuri nu functioneaza pe partea de protectii. Dupa noroc. Am testat cateva .....pana la limita. Rezultate optime: 35V 8 ohmi si 30V 4 ohmi . Dar atentie cu acesti 4 ohmi pt ca daca aveti boxe pe 4 ohmi , construite cu filtre gresit calculate cu zone de frecvente intrepatrunse prea mult, riscati sa oferiti kitului impedante foarte mici care il vor distruge cat ai clipi (daca nimeriti un kit caruia nu ii lucreaza protectia de overload).

E ok....am boxe de 8 ohmi si 50w se aude clar si tare cu super bass si voce clara si se incalzeste foarte putin. Eu am pus alt radiator in locul celui care a venit in pachet.
