TDA7498E 2.1 Channel Power Module — power, protected, and reliable audio drive for DIY and pro builds Key benefits — why you need this module Deliver strong, clean audio: Up to 160 W per stereo channel plus a 220 W subwoofer output lets you drive 4–8 Ω speakers with plenty of headroom for clear mids/highs and powerful bass. Flexible input support: Designed for AUX and USB sources and includes 5.0 support for a range of common input types, so you can connect computers, media players, and other sources without extra converters. Built for continuous use: Robust protection and an efficient heatsink enable stable, longduration playback at output without thermal throttling or sudden shutdowns. Easy, reliable wiring: current copper DC connectors and sturdy fence terminals reduce connection losses and wear, improving longterm signal integrity under heavy load. What it does and how it solves problems performance amplification: The TDA7498E digital amplifier delivers power per channel and a dedicated subwoofer channel, solving lowvolume, lowbass problems in small systems and DIY speaker builds. Input flexibility: Works with AUX and USB inputs (plus 5.0 support) so you won't need additional converters for common audio sources. Electrical and thermal protection: Builtin reverse polarity, undervoltage, overvoltage, overheating and short circuit protection prevent damage to the module and connected speakers, reducing risk during installation and heavy use. Durable connections: Copper DC connectors and reinforced fence terminals prevent loose or overheating connections that can cause dropouts or wire damage in current setups.
