Product description: RS-AMP kit - Noise Reducer

DIY digital amplifier kit by NoiseReducer. The amplifier is based onTripath TA2022chip, power of the amplifier is about2 x 100 Won 4 Ω impedance. The set includes a PCB with soldered SMD components and a set of THT components for individual soldering. The amplifier module supports two channels, so a stereo connection is possible. All components included in the set have been closed in antistatic pouches, which are additionally described, making it easier to find the right element.

RS-AMP amplifier

Preampandpower supplycircuits are located on the amplifier board. The module is powered by a toroidaltransformerwith a capacity of about 200 W. The power supply on the board has 24 V, 15 V and 5 V output. The module is characterized by power supply with a very low noise level, which is very important to obtain a very good sound quality.
A detailed description of the board can be seen in the author's video: Noise Reducer.

In our offer you can also findHead Amplifierby Noise Reducer and DAC.

Very good quality components. It's worth it.

Sebastian 09.12.2022 Confirmed purchase Translated review

The amplifier is designed correctly in terms of noise (better than the Chinese one, which I also have, anyway; the hum of the RS amplifier is barely audible from the meter on 86 dB/W speakers). The author did not save on components, although he could use a larger relay (100 mΩ is a lot for loudspeakers). Unfortunately, there is no schematic in the kit and it is not online either, so you have to check everything with an ohmmeter. The tile is twice as large as the Chinese one. I consider it a mistake to pack everything on one PCB for amateur construction, because a separate power supply, input switch and speaker protection could be easier placed in the housing.
