Black Box RCA to RCA Stereo Single Ended with Input Transformers

The RCA to RCA Black Box came from our use of input transformers on the test bench to isolate audio signals and minimize induced noise while testing. This same approach was used in Hifi’s golden era and has continued to be used in the Pro-Audio world.
This approach lowers noise floor and creates a common ground signal from the source to the amplifier improving the bass presentation, attack, balance, and depth. Midrange is improved with greater separation and depth. Transformers aid in the reduction of Sibilance and reduction of high-frequency hash. In short, this box will make your system quieter, and with improvements in the bass and midrange while reducing high-frequency hash/sibilance.
