Octave Filter 3-P Passive Filter System

It is almost impossible to find modern hi-fi systems lacking some level of digital signal processing today. The classic CD player has largely become obsolete, having been replaced by Internet-based sources, supplemented with hard disk storage media. This evolution means that signal connections to a network at the digital level are necessary to enable the interaction of the components.

Today's modern audio systems feature a number of digital and analog signal connections, to which a number of connections to the home's mains power are made. The modern household also features many systems and devices equipped with switching power supplies (e.g., LED lighting systems, laptop, solar panels) and radio controls (such as WLAN, etc.).

All these systems emit interference that affects nearby audio components and thus the overall sound quality of the hi-fi system.

Often an attempt is made to protect the system from interference by means of mains filters. However, this protection is very limited, as system filters work systemically only at very high frequency ranges and can in fact negatively affect the dynamics of a system. Disturbances in the important audio range are therefore unrestrictedly admitted to the audio system despite network filters and are distributed uncontrollably via the signal wiring. To eliminate the problem of propagation of conducted EMI, Octave has developed the Filter 3-P, a filtering system that acts directly in the path of interference, namely the analog signal cabling.

The Filter 3-P is a passive EMI filter system designed to be connected between any audio source component - analog or digital - and the pre- or integrated amplifier input to which it is connected. With regards to digital sources (for example with a DAC, streamer, cd-player, PC) the effect is most immediately evident. The Filter 3-P is available in two versions: fitted with single-ended RCA or balanced XLR connections. Thanks to the innovative technology implemented in this design, the same high level of noise-filtering is achieved via either of the RCA or XLR variants of the Filter 3-P.

The core of the Filter 3 is a highly specialized broadband interference suppression transformer.

The art of filter 3 was not to influence the signal, but to block interference from the bass region to the highest audio frequencies. The Frequency range of the Filter 3 spans from 10 Hz to 150 kHz / -1.5db, while the noise attenuation reaches about -80db at 1 kHz. This corresponds to a reduction of common-mode noise by a factor of 10,000. Compared with the attenuation of a line filter in this frequency range of -20 dB (corresponds to factor 10), this is a huge increase in the filter effect. (see diagram 1).

Digital-to-Analog converters particularly benefit from this measure because medium and high frequency disturbances negatively influence the sound-sensitive jitter behavior of these devices. Conversely, analog amplifiers benefit from the higher signal purity. Interference of the music signal with residual interference in the audio range is reduced, and the sound gains clarity, making even the smallest background details perfectly audible.

I was a little hesitant about buying a refurbished projector, but the $900 cost savings made the gamble worth it. The projector appears as new and was well packed. It was delivered in three days. And it is amazing, almost too bright! I researched a lot of projectors before buying this, my fourth projector and third Epson. This is one of the few that has a long throw lens and would fit into my film projector setup in our theater. This projector is simply great for movies. I don't do much screening or any gaming, so this is a perfect companion to my Oppo BluRay player. Well done!

Exactly what I expected from these bookshelf speakers

This is the best speaker in this price range I have ever heard. The clarity is crystal clear and the detail is amazing. Any genre of music I throw at comes out great! If you like a variety of music put these Monitor Audio Silvers at the top of you auditioning list.

Repeat purchase from Safe and Sound. Great audio gear at reasonable prices. They carry NAD products, my go to for anything audio. Great customer service and super fast shipping. will continue to purchase my audio from Safe and Sound. A++++

They are fantastic speakers, they really help bring out my vintage pioneer stereo system to its full potential. Also safe and sound was one of the best dealers I’ve ever dealt with, and I would recommend them to anybody looking for good electronics to keep them in mind.

Everything i want in a speaker. Fantastic.

I have never spent this much money for a stereo amplifier for. However, I must say that I am not disappointed! The clarity of sound from this amp is stunning! I'm very pleased with my purchase!

Aaron comes through once again! The new speakers and amp in the car sound amazing.

After several attempts I finally managed to get reset the pre-amp configuration as I wanted. The adjusted is buried in a vert unlikely location of the setup menu. Denon does a poor job writing their owners manual. Finally got the system running yesterday.

It was a gift to my brother. He says there are no cable or cords to connect it.

Great imaging and clarity. A bit heavy on bass but not excessive -was able to "tune" with the level controls.

Hearing things I never heard before! Awesome sound and clarity…..

Fast customer service. Mounted the speakers under the roof overhang of sun room facing my pool.sound fills the pool deck area, sound great, and have great power. Would buy again

Safe and Sound was right this table is beautiful once out of the box

It just what I expected, I'm just enjoying all the sounds from the "Music "

Thank you Safe and Sound for the attention to detail with my order! My speàkers were securely packaged for shipping and arrived in perfect condition! Outstanding service!

These are my favorite Klipsch bookshelf speakers, this is my third pair to purchase

The power conditioner is working great and i am very happy with it.

Great recommendation. Great equipment.

I love being able to give my Forte IVs a completely different vintage look by easily swapping my grill sets out.
