Hei
Laser ja, riktig det. Den blir brukt til å regulere forsterkning i takt med tilført signal på basen på transistorene. Denne reguleringen skjer med lysets hastighet.
Her er produsentens forklaring:
" The NL series of amplifiers utilizes Edge's 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 tenfold increase in gain. The additional gain is achieved while maintaining signal integrity (linearity) -- at light speed -- a first for solid state amplification. The result is the clear musical nature of the NL Series as observed by well-informed reviewers and buyers "

Laser i en poweramp?
Eller har de bare glemt CD-skuffen? ;D
PS forøvrig nydelig innmat!
