- Filtering RFI/EMI noise from switch-mode power supplies and wireless devices
- Amplifiers rated up to 2x150W or 1x300W
Key Benefits
DC Offset Correction
Blocks or cancels DC voltage in the mains supply — even a small amount of DC can cause a toroidal transformer to saturate and hum audibly.
Mains Noise Filtering
A built-in audio-grade filter circuit reduces both differential-mode noise from switch-mode supplies and common-mode noise from Wi-Fi and Bluetooth devices.
