The TDA7498 module is a class D amplifier, with dual-BTL 100W+100W output, single power supply, designed for home theater and active speaker applications.
Important: Using the amplifier with 4-ohm speakers can cause it to burn out. If you still want to use 4-ohm speakers, use the lowest possible voltage and be careful about the amplifier overheating. If necessary, use active cooling by applying a fan to the heatsink. Burning the module by using speakers with a value other than 8 ohms voids the warranty.

Necesita ventilator se ancalzeste an sarcina pe 4ohm 100w nu si are
Alimentat cu 24 dc merge foarte bine sunet clar
primul kit a fost defect.....dupa ce am primit altul functional testat la 30v 10A pe boxe sony rg660 6 ohm se aude incredibil pentru clasa D functioneaza decent si pe alimentator de 19v 4-5A de laptop recomand racirea activa pret calitate 10/10 recomand 100/100
Sunet plin cu inalte si bass suficiente ancat sa nu ai nevoie de un corector de ton.
Pentru boxe cu impedanta de 6 ohmi este buna
