Jos kuulet vahvistimesi virtalähteestä johtuvaa mekaanista huminaa – kytke vahvistimeesi iFi DC Blocker.
Pienikokoinen iFi DC Blocker sijoitetaan vahvistimesi virtaliittimeen.
Many large amplifiers have a really annoying mechanical hum (emitted from the toroidal transformer itself).
You can hear it when you place your ear close or next to the chassis.
This is caused by a small amount of DC voltage in the mains which makes its way through to the mains transformer, it will become ‘saturated’ and start to hum like a trooper.
The DC Blocker is a clever device that you place at the IEC (at the rear power inlet) and as its name implies, it stops DC from getting into the amplifier. It therefore eliminates amplifier transformer hum.
The bigger the amplifier, usually, the larger the toroidal which is susceptible to residual DC voltage. Just add the DC Blocker at the IEC to stop DC from getting in.
- Maximum rating >10A, continuous current rating 7A
- Small size, universal application, won’t block any other connectors, sockets, or cables
All the benefits of cutting out annoying hum with no drawbacks.
- Intelligently stops any DC voltage from the mains to eliminate transformer hum
- EMI shielding is retained
- Equipment safety is unaffected
