True Isolation, Protection, and Conditioning
Noisy AC power delivery adversely affects every aspect of your hi-fi or home theater system. The products of 'dirty' power include diminished resolution and dimensionality in audio playback along with lifeless colors and poor contrast in a video display.
Bryston's 10 outlet BIT15 Isolation Transformer power conditioner is the solution to common AC power line problems. The BIT15 has been designed as a complete power isolation unit which is ideal for protecting your equipment while smoothing out the current running through your home theater and home audio system.
"Every Note Was Crystal Clear"
"During many hours of music… every note, every chord, every downbeat was crystal-clear, liberated from noise, hum, or any other sonic distraction," reports Lawrence D. Devoe, MD in his June 15, 2015 post at Blu-raydefinition.com. "The BIT15 represents a very sound investment for home theaters that often run into the thousands of dollars. Highly recommended."
Most power conditioners are simple filters and do not provide isolation between the outside power grid and the inside power source. The BIT15 provides true isolation, along with low source impedance, and large enough instantaneous current for today’s most sophisticated and powerful audio amplifiers. Protect your system against diminished resolution and dimensionality in audio playback and video display.
A massive toroidal isolation transformer provides complete isolation and ensures sufficient reserve power capabilities to source high current requirements for high power systems.
The ever-present risk of severe power line spikes caused by everything from machinery and common household appliances to lightning storms is a constant threat to your system. Bryston provides state-of-art protection against power problems and series-mode surge without the use of failure-prone MOVs (metal oxide varistors).
Bryston power conditioners provide clean AC Power to enable you to obtain the performance your audio and video products are capable of. Plus, they protect your valuable equipment through the advanced series mode surge suppression.
Very Low Source Impedance and High Current
Bryston units present very low impedance to any connected device. A low impedance power source allows a power amp to instantaneously deliver high amounts of power. A typical 200 watt audio power amplifier demands 10 amps RMS current from a 120 volt line but may demand up to 50 amp instantaneous peaks. The standard residential wall receptacle can't supply the 50 amp peaks.
Series Mode Surge Suppression
Bryston power conditioners use the finest, most elaborate surge suppression technology available. Series Mode Surge Suppression does not shunt the spike to ground like MOV's do, and therefore the ground is infinitely more stable in a Bryston power device. Additionally, most MOV-based surge suppression units allow as much as 300 volts through to the protected components, easily enough to do substantial damage, whereas Bryston surge suppression has clamping voltage onset of ~2V above peak nominal voltage. Bryston units are built to withstand 6,000 volts and 3,000 amps surges, with up to 1000 repeats.
Total Isolation and Low Noise
Bryston power products provide isolation through their specially designed toroidal transformer, which creates a protected zone between the outside power grid and the connected devices. Such isolation creates a barrier to reject external noise sources such as motors, lights, and dimmers. Bryston power products provide noise filtering at a range from approximately 2,000 Hz to over 1 MHz. Other regular transformer based products do not start operating until nearly 10,000 Hz.
Bryston products utilize Plitron 'LONO' (Low Noise) transformer design technology that eliminates audible noise in the power transformer, regardless of line conditions, DC offset, and over-voltage. Bryston products perform at the NC10 level measured on the standard NC (Noise Criteria), which makes them suitable for use in very quiet environments such as professional recording and broadcast studios, as well as the most demanding consumer audio-video installations and systems.
Bryston products utilize Plitron NBT (Narrow Bandwidth Technology) to attenuate differential and common-mode noise without external circuits or components, and starting at a lower frequency (typically 2 kHz). Hear it for yourself! The Bryston result is startling.
"During many hours of music ranging from rock/pop (Counting Crows, Led Zeppelin, Michael Jackson) to folk (Joni Mitchell, James Taylor) to classical (Minnesota Orchestra, San Francisco Symphony) and, finally to jazz (Miles Davis, Modern Jazz Quartet, David Chesky), every note, every chord, every downbeat was crystal-clear, liberated from noise, hum, or any other sonic distraction. In short, my experience with the BIT15 was characterized by the liberation of all sound sources from their environmental bonds."
"I have used many power conditioners/surge suppressors but none designed quite like the Bryston BIT15 isolation transformer. As today’s home environments can profoundly affect the delivery of stable, noise-free electricity, I would consider power conditioners to be essential for audio/video systems. While not cheap, the BIT15 represents a very sound investment for home theaters that often run into the thousands of dollars. Highly recommended."
