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.
All the benefits of cutting out annoying hum with no drawbacks.
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.
ZERO DC Block technology – stops DC from getting into your amplifier and eliminates amplifier transformer hum.
High-performance glass passivated semiconductor. High-case dielectric strength of 1500VRMS. UL listed. Flame resistant IEC socket/connecter/chassis (Fireproof polymers UL94-V0).
EMI shielding is retained.
The DC Blocker removes such DC and eliminates such mechanical transformer hum, makes the transformer operate at the optimum environment. With the DC Blocker, there is 0 DC pass through.
| ZERO DC Block technology | Blocks incoming DC – up to 1,200mV |
| Voltage rating | 90 – 240 volts |
| Maximum current rating | > 7A |
| Max amplifier power | 880W or VA on 220v 440W or VA on 110v |
| Continuous current rating | 4A |
| Universal IEC | Hospital-grade IEC connectors |
| Dimensions | 68 x 37 x 32 mm / 2.7” x 1.5” x 1.3” |
| Weight | 63g / 2.2oz |
This is an excellent low-cost solution for removing mains DC offsets and certainly offers real sonic improvments for systems
