2 x 30 w audio power amplifier - DIY mini kit

This is the Whadda WSAH4003, a compact amplifier with powerful capabilities. Constructed with the TDA2616 IC, it has a maximum supply capacity of 2 x 15Wrms at 4 ohm or 2 x 10Wrms at 8 ohm. One of its standout features is the protection against overheating and short circuits, ensuring reliable and consistent performance.

It's been designed with user convenience in mind, allowing alternating current to be connected directly with the unit without the need for an additional rectifier and smoothing filter. The music power output stands at an impressive 2 x 30W at 4 Ohm, with an RMS output of 2 x 15 Wrms at 4 Ohm or 2 x 10 Wrms at 8 Ohm.

The amplifier also boasts a 70 dB channel separation, a frequency response from 7 Hz to 60 kHz (-3 dB), and a signal-to-noise ratio of 98 dB (A-weighted). With its input sensitivity of 300 mV / 150 kOhm, transient suppression on/off switch, and an overload and short-circuit protection that lasts for a maximum of 1 hour, the Whadda amplifier is a robust and reliable choice for any audio setup.
