50W Hi-Fi Audio Power Amplifier with Mute & Standby

  • 2999

This kit is based on an the amazing TDA7294 IC amplifier module from ST Electronics. It is intended for use as a high quality class AB amplifier in hi-fi applications. It has verylow noise and distortion, wide bandwidth and goodoutput current capability, enabling it to supply high power into both 4 and 8 loads. It has both short circuit and thermal protection, so is quite robust. With a suitable power supply, such as one based on Power Amplifier DC Supply, this module can deliver over 50WRMS into 4 or 8 ohms with < 0.1% Total HarmonicDistortion (THD) and < 0.1% IntermodulationDistortion (IMD). It is also suitable as a replacement or upgrade power amp stage for many existing amplifiers of between 30W and 50W output provided that they have a suitable power supply (most do).

The PCB is approximately 3.3" x 3.3" overall. Approximately 3.3" x 1.83" is the active circuit area and 3.3" x 1.47" is the pad for a heatsink. The heatsink is not included in the kit.
