Introducing the Equi=Tech R Series, the next generation of Balanced Power, designed from the ground up to nearly equal the performance of the original Q Series for half the price. Similar to the Q Series, there’s something unique about R Series that distinguishes it from everything else. In an audio component system, the most obvious difference is vivid low-end definition and mid-range realism that broadens the sound stage and makes the listening environment seem much larger than it is. Customers tell us that they perceive a much more realistic stereo image with finer detail and subtle nuance along with perfect phasing that places instruments on a stage in a way that rivals a live performance. What it does for video is equally impressive. Blacks become blacker without sparkles. HDR images retain more detail. An unmistakable and dramatic improvement in the resolution of the sound and video of an A/V system defines the R Series..
Balanced Power by Equi=Tech is used in almost every high-end professional recording studio and production facility in the USA today. Let’s be frank about this. It’s no small difference in sound or video quality we’re talking about here, but rather something on the order of astonishing. Professional engineers who use balanced power routinely report an increase in dynamic range and decrease in noise in their systems of between 16dB to 20dB. This is huge. What this means is that very subtle details that were once lost now appear in the music and in the video image that were once imperceptible. Performances are closer to live than ever before. Reducing background noise adds to the resolution and clarity of both audio and video.
In much the same way that XLR balanced audio lines can eliminate hum, electromagnetic interference (EMI), and noise, the use of balanced AC power lines in sensitive audio, video, or computer installations can make an enormous difference in system noise and signal integrity. But power distribution in North America, unfortunately, is not balanced. The distribution standards currently in use were derived from practices established over a century ago, when electric power use was limited to lighting and motors —long before any AC noise sensitive applications existed. The emphasis then was on convenience (from the power utilities — standpoint) and safety, but not noise cancellation
It’s a rather simple concept; in your home the AC wall socket that you normally use has three conductors: hot, neutral, and ground. Normally, if you measure the hot to ground you should get 120 volts, and if you measure the neutral to ground you should get 0 volts, but more often than you would imagine this is not what happens, i.e., hot vs. ground might be far less than 120 volts, and neutral vs. ground might be far more than 2 or 3 volts. These offsets produce common mode AC line noise that becomes audible in your audio system.
In a balanced AC circuit, hot vs. ground, and neutral vs. ground will both read 60 volts. In other words, the hot and neutral conductors are both at 60 volts. These voltages are phase inverted, given that most interference in a typical AC line is common between the two lines, the noise in the lines is eliminated when the two lines are added together. This is effectively known as Common Mode Rejection (CMR). The sinewave is noticeably cleaner, as seen below:
Mil spec oxygen free copper wire is used throughout the R Series assembly to further reduce random high frequency current distortion. This improves an already near perfect mirror image output and further widens its range of noise attenuation. The Model R’s switches and circuit breakers are the finest made and they’re duty rated for over 1/2 million operations. Every component part used in the Model R has been selected because it is the best of its kind for the money. There is nothing that compares in quality or performance to the Model R in its price class..
The Model R has a simple yet elegant appearance. It features an anodized aluminum front panel that is available in black or silver. There is one blue LED indicator light above the input power switch and one above each output standby switch indicating power status at both the input and the output. The input power LED also doubles as a TVSS status light that indicates active surge protection when lit. In the rare event that it stops working and the output LED still works, this indicates that the surge protector has taken too many nuisance voltage spikes and its days are done. In the rare event that this occurs, the Model R’s grounded Faraday shields provide excellent redundant surge protection until the TVSS module can be replaced and it is an inexpensive and easy thing to do.
On the rear panel, there are 12 AC outlets provided. One GFCI outlet is independent from the front standby switch(es) and is constantly left turned on for use with components that require continuous power for a clock or to maintain volatile memory. Of the 10 remaining outlets, 6 (white) are for analog components such as amplifiers and pre amps and 4 (gray) are specially filtered outlets for digital components. A circuit breaker on the rear panel protects the system from overload and from potential short circuit fire hazards in electrical power cords and downstream connected equipment.
Commercial / Industrial Applications:
Award winning Equi=Tech Wall Cabinet Systems are factory pre-assembled power distribution centers for hard wiring balanced AC power into a facility – a complete balanced power distribution system built into a wall cabinet. Only minimal installation is required eliminating many expensive hours of labor and hard to find electrical parts. All the necessary components such as transformer, breakers, GFCIs, surge protectors and line filters are factory assembled using the highest quality materials and components.
Wall systems are designed to blanket an entire facility with clean and phase coherent balanced AC power that remains stable regardless of how they are loaded down. 5, 7.5, 10, 15 and 20 kVA sizes provide 50, 75, 100, 150 or 200 amps respectively – ideal capacities for most studios and modestly sized theaters or auditoriums. These systems utilize the same precision toroid isolation transformers as Equi=Tech rack systems but they are much larger with a greater capacity. Wall systems are the easiest way to provide clean power for a larger facility, doing so with the assurance that the system will remain quiet regardless of what equipment is used or added to it at any time.
