4-Channel Digital Amplifier (Kamaden) - TA2041 Based Kit Build

This is ideal for those who want to input their computer's audio output into this unit and connect the output to speakers to enjoy music and videos. You can connect it to two speakers (left and right) and use it immediately.
Although it has been over 10 years since it was made, I have been using it again for the past three years. It is in perfect working order. I have decided to sell it due to downsizing my audio equipment after moving.

Dimensions: Width 305mm, Depth 240mm, Height 55mm (including protrusions such as terminals)

Recommended for those who can build circuits as a hobby.
This is a Kamaden TA2041KIT wired using TRIPATH's TA2041 (Class D stereo digital amplifier: 1-bit ΔΣ modulation 4Ch 75W (4Ω) high-efficiency, low-distortion, high-quality amplification). The power supply is also housed in a Takachi case, and it was used to drive JBL speakers in a 2-channel configuration. After construction, it was used regularly for about 5 years but was put into storage when I switched to a vacuum tube amplifier. I started using it again a few years ago with the introduction of a silent PC.
If you wish to use it in 4-channel mode, some wiring of the output terminals will be necessary. For use as a full-fledged audio amplifier, we recommend replacing the 12V DC power supply with a different one for this unit.
It can also be used in vehicles as it is a 12V specification. You can remove the power supply from the case and connect it to a vehicle's power source.
Toshiba has published the specifications for the TA2041.
