 EDGE
 ELECTRONICS
Edge Electronics is an American company that has been in business since 1987. Each component they manufacture is lovingly assembled by the principals and just a few trusted highly-trained technicians. The company is currently the only company in the world that uses laser-biased transistors in their amplifier design.

 

 

 
 Sound
Why are some astute listeners convinced that Edge amplifiers are the best solid-state amplifier in the world today?

Perhaps it is the speed - where notes just appear when they are supposed to appear- rise and fall naturally and exactly as they should in response to the music - and then die away, without inappropriate lingering. Listening to most, if not all other amplifiers, the listener may feel that the notes are being dragged through molasses. Or perhaps the listener feels that they ordered each note from a restaurant across town, the restaurant was late with the delivery, had burnt the note in the bargain, and the note, unfinished, had a lingering smell the next morning.

Perhaps it is the smoothness of the notes rendered by the amplifiers. They are grown organically, as opposed to carved out of stone in some kind of misbegotten caricature  of the note right out of Dante's Inferno - as so many solid-state amplifiers have done in the past.

Perhaps it is the dynamic capability - the ability to render the inner dynamics which produces notes that sound so entertaining, so real, just like when they were made by the musicians themselves - that the listener is emotionally moved, and often completely overwhelmed by their favorite music.

Or perhaps it is the ability to sound like the finest tubed amplifiers - speed, smoothness, inner detail but without the 2nd harmonic distortion, the heat (the Edge amplifiers run cool), the maintenance and placement issues and all the issues associated with most tubed designs at the extremes of the frequency spectrum.

What we have here is the realization of the promise of solid-state amplifiers; conceived in the 1960s, and after 40 long years of suffering, we finally have a maintenance free, family friendly, general purpose amplifier that surpasses all but perhaps the most ingenious, special-purpose tubed-amplifier designs.

Solid-state amplification can finally sound as good or better than the technology it is (supposed to have) replaced!

All we know is that these amplifiers just simply have the ability to present seamless, top to bottom, inside out, delicious music without doing anything seriously wrong - unlike every other solid-state amplifier in existence.

 

 

 

 

 

 

 
 Technology
The Laser-Biased Transistor

The "NL" series of amplifiers utilize EDGE proprietary Laser Optical Bias Circuitry.  This new circuit incorporates a 630 nm wavelength laser in each channel operating directly on the silicon substrate of the bias transistors.   The laser bias circuit in turn is part of a servo feedback network.  As the signal rises, the output of the laser increases, and as the signal decreases the laser output falls.  This keeps the bias at the optimum operating point allowing a 10 fold increase in gain.

The additional gain is achieved while  maintaining signal integrity (linearity) - at light speed - a first for solid state amplification.

The "NL" series also features oversize binding posts and up to 16* low leakage snap lock 10,000 F caps per channel.  Also the new low leakage / low field medical grade transformers are housed in magnetic stainless steel enclosures for non induction and low noise performance.  Chassis construction on these amplifiers is 1/2" thick 6061 aluminum, held together with marine grade stainless steel machine screws.  Heat sinks machined from solid 6061 bar stock keep transistors cool without fans.  The output stages utilize up to 32* N channel bipolar transistors for extremely low output impedance.

DESCRIPTION

The NL Reference monoblocks are Edge Electronics' statement amplifiers. These 800 watt, 220 lb. monoblocks are very high voltage, very high current output amplifiers. The Edge Reference monoblocks continue the Edge Electronics' tradition of building extremely efficient amplifier designs.

And one has to keep in mind that these are Edge Electronics watts, which are cleaner, faster, smoother and more detailed than any other solid-state amplifier being made today.

Up until now, one had to use very large, 600 to 700 watt tube amplifiers to product the kind of forceful and overwhelming, yet pure and uncompressed crescendos that are required by many types of music. Unfortunately, large tube amps have problems in that they generate large amounts of heat and use large numbers of tubes that require maintenance after some amount of time.

Most solid-state amplifiers are usually harsh and unpleasant to the ear, especially after extended periods of listening, and even more so when listening at loud volumes. As anyone knows who has heard any of the Edge Electronics amplifiers, they have licked this problem using their laser-biased transistors.

Finally, those that want this level of performance but did not want to sacrifice the conveniences of solid-state amplification, now have the option to achieve their dreams with the NL Reference.

RECOMMENDED USAGE

The NL Reference monoblocks are excellent for systems that want over the top performance on a level that only a few people in the world have experienced. These monoblocks take the performance of the NL Signature Ones and extend it to the farthest reaches of what humans have so far imagined.

DESCRIPTION

The NL Signature One.1 monoblocks are the ultimate amplifier in the line of NL amplifiers. While retaining the overall character of the smaller NL amplifiers - the speed, smoothness and micro-dynamics - the NL is just so much better in all respects: the added power allows notes, at all frequencies, to explode within the force and passion that the music is demanding. There is much more authority in each note, you can just hear when the musician wanted to start the note, the emotion they wanted in the note, and exactly when they wanted the note to end. Essentially, it cleans up the many layered window between musician and listener.

The NL series amplifiers all use the same sized chassis and only differ in their outward aesthetic design and, of course, their internal electronics. The heatsinks on NL Signature One are wavy in form, unlike its siblings. All NL series amplifiers run only slightly warm to the touch and contain no sharp edges, which makes them user, family, placement, and summertime friendly.

"The EDGE NL Signature One.1 is the quintessential expression of technology serving music.  Using EDGE proprietary Laser Biased Control circuitry this amplifier redefines "linear".   Massively constructed and well endowed throughout, it becomes "invisible" in all situations.  Use this one for your most demanding audio reproduction requirements."

RECOMMENDED USAGE

The NL Signature Ones are excellent for systems that either: need or want a lot of power, are too bright, the listener would like to use tubes but cannot or does not want to deal with tube's negative environmental issues (heat, maintenance, foot-print), or those systems that do not have enough PRaT (pacing, rhythm and timing).

Each transformer operates at 96% efficiency. Regulation equals 4%
Laser Source Front Panel Illumination (one per chassis)
