If you’ll hear audible hum inside a powered audio product, especially with a toroidal transformer inside, our DC Blocker was designed to either lower or remove that noise.
Although this unit will still provide them with power, there is little benefit in doing so. In a switchmode power supply the AC mains is first rectified into DC, after…
The majority of audio electronic equipment uses a power transformer or transformers for their power supply. Mains power starts out being a pure sine wave at the power station but…
The DC Blocker aims to reduce noisy physical transformer hum caused by DC on the mains. It’s designed for equipment that uses a mains power transformer in its power supply.
This unit is mainly designed for source equipment and amplifiers with a power transformer rating up to 500W (for 230V) or 350W (for 115V). Using equipment with a higher power…
As toroidal and R-core transformers are more efficient than conventional EI transformers they are quite sensitive to any DC entering them from the mains. If your equipment contains one of…
