The NL Signature One.1 monoblocks are the ultimate amplifier in the line of Edge NL amplifiers, second in line only behind the $45,000 Reference amps. 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 Signature One amplifiers use a separate power supply for each half of the sine wave, two power supplies per chassis. Everything is built symmetrically -- even the internal wire lengths are the same. The NL Signature Ones feature 50 percent more output transistors than the other NL amps, thus cutting the output impedance by a factor of two.
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."
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 µF 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.
