S8 is the latest high capability integrated  amplifier, building on the sustained success of models like the R30. Based on decades of experiences on research, development and handcraft for audio amplifiers by Dussun, every new design in S8 aimed at the clear objective for sound quality and tone improvement.In order for its output music signal by S8 possessing high fidelity against the music source, output characters matching electrodynamic loudspeakers’ electric-sound characters, The design of S8 went through a long time repeated audition, measure and improvement process，which made the finished S8 achieve the ideal matching level for signal magnification circuit, volume control circuit, power supply system and interior construction. In addition to the technical specification for a hi-end amplifier deserved，S8’s sound possessed outstanding quietness, rich details, dense timbre and transparent and spacious tone. It escorted the audience to rediscover the performing atmosphere and rich sound spacial information from those familiar CDs which missed before.

●left and right channel fine synchronized high precise volume control

Considering the volume control device is one of the souls of an amplifier, S8 employed Dussun developed volume control device, which set up by a 16-bit digital controlled analogue circuit and possessed 1/65,535 level super fine resolution within whole volume control range.  This volume control comprising  circuit high linear solid state switch and precise resistance, ensured precise synchronization of S8’s left and right channel volume control at any position within its 80 dB volume control range. All problems of sound quality degradation and application intervention from frequency and phase distortion, volume synchronization error, sliding friction noise, limited lifetime attribute to traditional volume control potentiometers’ various voltage ratio, was eliminated by S8 volume control. Either working principle or practical performance, S8 reached the highest technical level fully among the state of the art hi-end amplifier volume control and pride.

●Low distortion, Non-feedback at poweroutput terminal,Poweroutput

   stage：

The newest designed “Optimized Self-Adaptive Bias Circuit” Improved significantly linear in output stage signal crossover region, while maintaining large power output without switch distortion. Much different from routine design which removed output stage feedback resulting in non-linear distortion large increase, especially at high frequency side, S8 accomplished super low crossover distortion by its “Optimized Self-Adaptive Bias Circuit”. Along with the most nature and spacious tone from a “non-feedback at output terminal amplifier”, S8 achieved the perfect result of full power output, low distortion, high sound quality in whole audio frequency.

●Thorough independent dual-mono channel design：

S8 left and right channel circuit as well control units were equipped with individual independent power supply system. Data used to control individual channel was transmitted in term of optical. Absolute electric isolation made S8 is true to its name, dual mono channel amplifier, which working as same as two sets of precisely synchronized independent mono channel amplifiers, nil stereo crossover between left and right channel, resulting in pinpoint accurate sound images.

●Strong control and pre-set function：

  Individually pre-set gain level for all input terminals

  Individually pre-set channel name for all input terminals

  Display screen brightness adjustable for 4 levels

  Maximum volume pre-set to protect expensive loudspeakers

  Fade-in volume when switching on

  Aluminium full function remote control unit

About “Hyper Class A”

The “Hyper Class A”  is a “Green” Class A solution, whose technically successful adaptive-bias circuit achieves the extra large class A power output objective under conditions of low-power consumption and low heat producing. The adaptive-bias circuit with an ideal specification permits the amplifier to maintain class A mode output even if the speakers’ impedance drops largely and output power increases several times. This situation is different from the traditional pure class A amplifiers’ inevitable situation of returning to class B when the speaker load impedance goes down, and is much close to the ideal class A amplifier essence.
