RF Noise
RF ‘noise’ (WiFi and all other radio signals) is picked up by all cables, electronics and loudspeaker coils unless perfectly screened against RF. RF does ‘interfere’ with the audio signal so filtering out RF noise is an effective way of improving audio fidelity.
The RF Blocker is entirely passive, has no effect on impedance or any other amplifier/speaker characteristics other than eliminating a broad spectrum of radio frequencies, both going into the loudspeaker from the amplifier and RF re-entering the amplifier’s circuit via the loudspeaker cable.
The resulting increase in audible fidelity is usually clear to hear as an increase in musical coherence, the high frequencies are clearer, mids cleaner, the bass tighter and less ‘boxy’, the sound stage improved. The overall effect is of less ‘confused’ musical details, getting you closer to the musical event.
As amplifiers and speakers are designed and built differently, the effect is slightly different in each amplifier / loudspeaker / loudspeaker cable combination, but there is almost always an audible improvement.
Suitable for use with all types of amplifiers (Class A, A/B, and D) and all types of loudspeakers and cables. They are not compatible with active loudspeakers.
The connected-fidelity™ RF Blocker is based on sound electronics principles. There is no ‘Angel Dust’ used in this product!
The RF Blocker is designed to audiophile standards
High quality electrical components are housed in a die-cast aluminium box acting as a Faraday cage ensuring no further RF interference is picked up to enter the audio chain. The short attaching cables are multi-strand OFC copper, connectors are gold plated.
Your audio system
The RF Blocker’s will work to a lesser or greater degree with all audio systems and the benefits will carry through to any further upgrades of amplifier or speakers or cables you may make in the future.
If you are bi-wiring, you can use two pairs of RF Blockers to maximize the benefits but one pair will also make an improvement. Experiment fitted to the bass terminals, then on the mid/treble and decide which option sounds best to your ears. We normally find it’s the critical 1-5,000Hz range (mid-range) that makes the most audible difference, but it is worth experimenting. It is possible to fit at the amplifier end of course.
