Greetings from us at AudioVision!!
Best of luck to you and your loved ones during these trying times! We are open during normal business hours, and are here to help you with your music therapy! Feel free to give us a ring anytime at 4I5 6I4 III8 to discuss the Technics, or any other items we sell! Check our our listings at http://audiovisionsf.com/?page=specials or write us at info[at]audiovisionsf.com!
We have a very special offer today in the SE-R1 power amplifier from Technics! It's our demo floor sample in 9/10 condition. It has seen very very minimal usage, and comes with all the original boxes, packaging, and materials. Also, as we are a Technics dealer, it comes with FULL WARRANTY AND DEALER SUPPORT!! A feat of modern engineering, there is no other power amp out there that will perform as well for the price we are asking for it. It can be used with Technic's own preamp, but works perfectly with other preamps, just ask us our advice on which one you have or are looking at and we'd love to give you our opinion on the synergy!! WE ALSO HAVE A DEMO PREAMP AVAILABLE TO SELL AT A DISCOUNT, SO PLEASE ASK ABOUT DETAILS IF YOU ARE INTERESTED IN BOTH UNITS OR THE PREAMP ALONE!
We are more than happy to provide additional photos as well. And for this price we shall also include shipping - but be aware this has been priced this low to sell this low.
"JENO Engine (Jitter Elimination and Noise-shaping Optimization)
Jitter is a major cause of distortion in digital systems, and is caused by mis-timing in the master clocks used in digital-to-analog conversion. To eliminate the degradation of sound caused by jitter, Technics has developed an original jitter reduction circuit, comprising a clock generator in the noise-shaping system to reduce jitter in the low-frequency range and a high-precision sample rate converter for suppressing jitter in the high-frequency range. Thus it reduces jitter in an ideal way over the entire frequency range.
This works with a newly-developed and original high-precision PWM (Pulse Width Modulation) conversion circuit, optimizing the noise-shaping speed, the degree and requantization number, and the PWM gradation, in order to convert high-resolution signals to PWM without causing any damage to the dynamic range. These new technologies enable new Technics digital amplifier designs to reproduce the natural and delicate nuances of music.
GaN-FET Driver (High-speed and Low-impedance Power Devices)
In the speaker-driving section of the amplifier, Technics has employed a high-speed GaN (gallium nitride) FET driver device with super-low resistance. This enables the construction of a high-power amp using a single push-pull configuration, allowing the length of the large current carrying signal path to be shortened, and resulting in outstanding linearity regardless of the sound level.
LAPC (Load Adaptive Phase Calibration)
The impedance of a speaker is not constant: it varies according to frequency, thus altering the loading on an amplifier and therefore potentially the sound. Technics is able to measure an amplifier's frequency amplitude-phase characteristics with speakers connected, and has developed a speaker impedance adaptive optimization algorithm using digital signal processing to achieve ideal impulse response. Correction processing based on the new algorithm achieves a flat frequency response for both amplitude and phase, not possible in conventional amps, and delivering a sound with rich spatial expression.
