5.0 TDA7498E Digital Power Board 2.1 Channel 160Wx2+220W Speaker Stereo Audio AMP Module ZKHT21 power 2.1 amplifier module designed for clear, dynamic sound and easy integration into stereoplussubwoofer systems. The ZKHT21 combines a TDA7498Ebased digital power stage with a 2.1 channel layout to deliver substantial output for left/right speakers and a dedicated subwoofer channel, making it a practical choice for DIY audio builds, home theater upgrades, and compact professional installs. Key benefits Substantial output for realworld listening: 160 W per stereo channel plus 220 W for the sub channel gives you the headroom needed for impactful bass and clear mids/highs without pushing consumerlevel amps to distortion. One module for full 2.1 setups: Integrates stereo left/right amplification and a dedicated subwoofer channel in a single board, simplifying wiring and saving space compared with separate amps. Reliable amplifier core: Uses the TDA7498Ebased digital power architecture to provide efficient amplification and consistent performance under load. Ideal for DIY and system upgrades: The board form factor is suited to hobbyist enclosures, custom speaker cabinets, and rack or shelf installations where a compact, power amplifier is required. Key attributes Model: ZKHT21 (version 5.0) Amplifier chip: TDA7498Ebased digital power board Channel configuration: 2.1 (stereo L/R + subwoofer) Rated output: 160 W x 2 (stereo channels) + 220 W (subwoofer channel) Functionality: Stereo audio amplification with dedicated lowfrequency channel for subwoofer integration Compatibility: Designed for passive speaker systems and subwoofers that match the module's power and impedance requirements; suitable for linelevel inputs from common audio sources Form factor: Amplifier module/PCB for integration into enclosures or projects Typical applications: Home theater upgrades, DIY speaker systems, desktop audio solutions, small publicaddress or entertainment systems How this module solves common problems Lowvolume, thinsounding stereo systems: Replaces weak amplifier stages with a power module that restores clarity and dynamic range. Complex system builds: Combines stereo and subwoofer amplification in one board so you don't need separate amps or complex crossovers for basic 2.1 setups. Space and integration constraints: Offers a compact module option for builders and installers who need power without a large chassis. Practical use cases Home theater 2.1 upgrade: Power your left/right bookshelf speakers and a powered passive subwoofer from a single board to improve bass response and overall dynamics for movies and music. DIY speaker cabinet project: Build a custom active speaker system or a subwoofer cabinet with integrated amplification using the ZKHT21 module as the heart of the system. Small venue or multiroom audio: Use the module to drive speakers in a café, small event space, or dedicated listening room where a compact, output amplifier is preferred. Installation and integration notes Match speakers and subwoofer to the module's rated output and appropriate impedance for reliable, longterm performance. Provide an appropriate linelevel input source (preamp, receiver, or audio interface) and a power supply capable of delivering the required voltage/current for the module. Ensure adequate cooling and physical mounting in your enclosure to maintain stable operation. What to expect in operation Powerful lowfrequency support from the dedicated 220 W sub channel, while the 160 W perchannel stereo outputs deliver clear mid and frequency detail. Efficient digital amplification behavior consistent with TDA7498Ebased designs, offering a balance of power and thermal efficiency suitable for many installation types. The ZKHT21 5.0 TDA7498E Digital Power Board provides a focused solution for anyone needing a compact, power 2.1 amplifier module. Use it to underpowered electronics, build custom speaker systems, or streamline a multichannel installation with a single robust board.
