TORUS PowerBlock Series Toroidal Isolation transformers with compact footprints and rugged construction.
Torus Power PB series of ultra compact, most cost-effective and portable Toroidal Isolation Power Transformers, and the most affordable products in Torus line-up.
Made in Canada with Plitron toroidal transformers of excellent transformer winding technology and a series of unique patents.
*Toroirdal Isolation
*Noise Filtering
*High Instantaneous Current Capability
*Lightning and Surge Protection
Rated at 1,000VA, which is suitable for mid-power compact systems, source components, TVs or projectors etc.
It provides basic circuit protection with Transient Voltage Surge Suppression (TVSS).
Experienced AV/HiFi enthusiasts understand that after a sound system is basically finalized, in addition to upgrading accessories like wires, isolation feet, etc, the most important measure is to have the power supply improved.
The overall idea is to ensure the bandwidth and stability of the power supply as much as possible.
Many senior AV/audio-philes not only build professional AV/HiFi rooms but also set up a “dedicated power line” for the equipment.
High-purity high quality conductors, plugs for good connection stability and high oxidation resistance.
PB4 is basically superposition of 2x PB2.
PB4 has 2x toroidal transformers, with output current of 4.4A, power load of 500VA x2
**Same with the PB10 model in 110V countries.
It can effectively isolate the noise caused by cross-current interference in power grid.
As an advanced power conditioner, PB4 is also equipped with anti-surge function for equipment safety.
One can expect pure and stable power supply, resulting in better separation, quiet background, extension and low frequency dive in sound restoration.
“During the trial of Torus Power PB4 515R, I first focused on the dynamic performance, secondly, I tested the applicability and other details of it.
The dynamic compression that is always a “weak spot” for many power conditioners, doesnt occur on the PB4 515R, which is very surprising!”
“I selected some very dynamic orchestral recordings and pop musics with lots of low frequency for testing.
Whether it’s a dense string group or a grand timpani, whenever the low-frequency energy comes, the entire system achieves stable performance, compared with previous power conditioners, the improvement in low-frequency energy is very obvious.
Pop music has also been significantly improved in terms of impact, speed, and volume, which also makes the music more present and engaging.”
“Previously, I didn’t feel there was anything wrong with the music background. But after switching to PB4, taking Tsai Chin’s “Moonlight Serenade” as an example, I clearly felt that the music was “out of tune”. “Stability” is stronger, the music layers are clearer, the positioning is clearer and more natural, and the fullness and positioning of the human voice are more realistic.
The original elements of the music are more prominent, the music performance is more stable and calm, and the music’s appeal is stronger.”
“Take Robert Shaw’s version of “Carana Burana” as an example. Many times in the past, when replaying the previous paragraphs, I always felt that the details of the music were not full and rich enough. Only in the second half, when the music started to become exciting, could the various details be released. After the system was switched to PB4, even in the low-volume passage at the beginning, various details of the choir were clearly audible, without having to search hard.”
“The clarity, separation and gloss of the music are all there. For further improvement, saying “huge” is a bit of an exaggeration, but the contrast is obvious and audible. This also illustrates from one side the importance of high-quality power supply for the final sound performance of the audio system.”
“Connecting the author’s desktop audio system with decoders, headphone amps, and speakers, the most obvious change in the listening experience was similar to the previous listening experience in the HiFi system, that is, the sound quality The stability has been further enhanced, and the separation, clarity, and resolution of various elements in the music have audibly improved and changed.
Just from the listening experience of the headphones, I didn’t find the low-frequency very solid and enjoyable. After PB4 entered the system, I felt the cohesion and cohesion of the low-frequency. The impact has been significantly improved, the low frequency is cleaner, and the sound lines are clearer.”
