Due to the great increase in airborne and AC-line-transmitted radio signals, combined with overtaxed utility lines and ever-increasing demands from high-definition audio\/video components, A\/V systems fall short of getting the power required to fulfill their potential. Furthermore, today's power amplifiers are strained for instantaneous peak-current demand even when driven at modest volumes. Although there has been a substantial increase in dynamic range from audio software, the loudspeakers are often no more efficient than they were 50 years ago. This places great demands on an amplifier's power supply, as well as the source of AC power supplying it. In order to properly accommodate the promise of today's ever-increasing bandwidth and dynamic range, Niagara 7000 offers extremely low system noise and provides superior current delivery across a very wide range of frequencies. Differential sample tests and spectrum analysis prove that up to a third of a high-resolution (low-level) audio signal can be lost, masked, or highly distorted by the vast levels of noise riding along the AC power lines feeding audio components. This noise couples into the signal circuitry as current noise and through the AC ground, permanently distorting and masking the source signal. Sensitive audio components require better alternating current.\u003cbr\u003e \u003cbr\u003e \u003cstrong\u003eHolistic, Science-Based Noise-Dissipation Approach Proves Superior\u003c\/strong\u003e\u003cbr\u003e When it comes to noise dissipation for AC power, many approaches can yield meaningful results. However, some approaches impart unintended effects – ringing, current compression, and non-linear distortions – that can render the cure worse than the disease. Niagara 7000 takes a holistic, science-based approach to AC power technology and represents a comprehensive solution to the ever-increasing noise that plagues today's power lines. It uses optimized radio-frequency lead directionality, electrical capacitor forming technologies developed by Jet Propulsion Laboratories and NASA, and AC inlet and outlet contacts with heavy silver plating over extreme-purity copper to ensure the tightest-possible grip.\u003cbr\u003e \u003cbr\u003e \u003cstrong\u003eInstantaneous-Current Reservoir of More Than 90A Peak\u003c\/strong\u003e\u003cbr\u003e Niagara 7000 also employs the patented AC Ground Noise-Dissipation System, the world's first dielectric-biased AC isolation transformers, and the widest bandwidth-linearized noise-dissipation circuit in the industry.

This coaxial design provides outstanding stereo imaging even off axis. Because sound is produced from a single point, it comes off the speakers in a truly spherical and time-aligned wavefront. This preserves the harmonic structure of complex instruments and vocals, recreating the true acoustic sound field from a loudspeaker that is far less dependent on room location.\u003cbr\u003e\u003cbr\u003eThe F1 series IsoFlare drivers, the high-frequency unit features a highly rigid 3” titanium HF diaphragm for smooth and unstressed performance, with a massive Neodymium magnet incorporating a vented rear chamber to place low-frequency resonance well below the crossover region. This enables a very low 750Hz crossover point for the most realistic rendition of vocals. The HF driver uses a high-power handling edge-wound aluminum voice coil on a Kapton former with pure copper shorting ring for lowest distortion. Its unique IsoFlare annular waveguide has computer-optimized geometry to provide linear expansion into the room for the smoothest frequency response.\u003cbr\u003e\u003cbr\u003eOn the low-frequency section, a multi-fiber paper cone gives natural sounding midrange and extremely clean transient behavior even at concert realistic SPLs. The twin roll fabric cone surround (floorstanding models) and FyneFlute surround (standmount models) effectively terminates cone energy without time-smearing, remaining cohesively integrated to the HF driver irrespective of listening volume. The high-power LF motor system uses a giant ferrite magnet with a rectangular copper voice coil on aluminum former for class-leading power handling. The complete F1 series IsoFlare driver is built into a rigid cast aluminum chassis to eliminate unwanted vibrations and coupled to the cabinet’s internal bracing spars through a semi-compliant bonding material for exceptional damping at the driver\/cabinet interface.\u003c\/p\u003e\n\u003ch4\u003eBass Trax Tractrix Diffuser System \u003c\/h4\u003e\n\u003cp\u003eThe patent pending BassTrax Tractrix profile LF diffuser system is a complex yet refined approach to bass loading and reflex porting. It incorporates a twin cavity cabinet design with a tuned waveguide port firing downwards from the reinforced lower panel of the cabinet. This loading technique broadens the tuning frequency to reduce cone excursion and acts as a damping system that blocks potential standing wave resonances produced by the main internal port between cavities.\u003cbr\u003e\u003cbr\u003eThe lower cavity bass port vents downwards onto the BassTrax Tractrix profile diffuser. The unique, mathematically derived tractrix profile maintains a true 90 degree angle at each intersection of the expanding wavefront, so converts plain wave LF energy into a horizontally expanding spherical 360-degree wavefront with no loss of total energy. The result is seamlessly uniform LF integration into the room and a loudspeaker that is far less critical of room positioning.\u003c\/p\u003e\n\u003ch4\u003eCrossover Design\u003c\/h4\u003e\n\u003cp\u003eThe F1 series crossover is a no-compromise design, hand-built onto vibration-damping fibreboard panels using the world’s finest electronic components and cables and fine tuned to deliver truly class-leading performance. Leaning on decades of premium loudspeaker design experience, the design team refined the component list through finite element analysis, and computer modeling as well as measurement and critical auditioning by Fyne’s top engineering and acoustic personnel.\u003cbr\u003e\u003cbr\u003eThe component roster includes low-loss LF laminated core inductors, non-inductive thick film resistors and Claritycap’s highest grade HF polypropylene capacitors. Neotech ™ PC-OCC internal wiring provides highly transparent signal transfer, connecting to the loudspeaker cable through WBT Nextgen™ gold plated bi-wire terminals. Once fully assembled and tested, every F1 crossover is Deep Cryogenically Treated. This super freezing and slow thawing process relieves microstresses in components, wiring and solder joints, maximizing signal transfer and delivering greater transparency to the sound.\u003cbr\u003e\u003cbr\u003eFurther F1 series refinements include a fifth earth terminal that grounds the driver chassis to prevent radio frequency interference effects from masking fine detail.

However, this is not a hard ceiling. Vinyl, tape, and high-resolution digital formats routinely capture ultrasonic energy, and even some CDs allow material to leak above the cut-off depending on the filters used. More importantly, the benefit of SuperTrax is not limited to “playing” ultrasonic tones.

The main tweeter’s behavior hasn’t changed, but the system as a whole no longer depends solely on its ragged roll-off.

Berkeley's perfected technology goes beyond sounding excellent to simply sounding real.\u003c\/p\u003e\n\u003cp\u003eThe new proprietary RF waveguide isolation technology used in the reference series 3P produces unprecedented imaging precision, timbral purity and resolution.\u003c\/p\u003e\n\u003cp\u003eBerkeley DACs use a commercial delta-sigma convertor, but turn off all filtering and DSP functions except for the central conversion circuit.
