| Description | HiFi Amplifier stereo, 2x 140W, AWRAT, DIDRC, Wolfson 192kHz/24bit DAC, digital audio inputs Integrated Stereo Amplifier Onkyo A-9070 includes everything you need for true hi-fi reproduction. You can even choose from four preset video modes: integrated amplifier, power amplifier, preamplifier and split preamp/power amp. This is a great alternative to AVR, against which you have the high-end quality stereo reproduction for a fraction of their price and at the same time you do not take expensive CD/DVD player - all digital audio amplifiers to bring through one of the three digital inputs and the best transmitters already Wolfson to see to it that everything sounds as it should. AWRAT (Advanced Wide Range Amplifier Technology) - Onkyo A-9070 utilizes a range of proprietary technologies for optimum sound. First DIDRC (circumference reduction of dynamic intermodulation distortion) Still, they are outside the normal range of human hearing, the frequencies above 100 kHz susceptible to clock pulses and other forms of distortion digital devices. Such extremely high frequency distortion may generate "Impact Tourism", which has yet to affect the character of the original sound. By improving linearity and reducing distortion in the extremely high frequency range and Onkyo DIDRC effectively reduces audible noise. Second design for low negative feedback (NFB) Too much NFB makes the system vulnerable to a counter-electromotive force from the speakers, resulting in a decrease in perceived sound quality. To avoid this, it focused Onkyo to improve the frequency response and lower distortion, without reliance on the effect of NFB. 3rd closed circuit grounded A-9070 uses a sophisticated system of closed circuit in which each circuit has a separate connection to the source. This helps to eliminate noise complete each circuit and ground maintenance without distortion. 4th HICC (high instantaneous current capability) By working with load current up to 100 amperes, HICC enables an amplifier immediately eliminate reflective energy speakers and immediately send another signal. This high power amplifier allows to manage fluctuations in impedance that occurs at each stereo listening. 5th Twin Mono Symmetrical unit Power units for the left and right channel amplifiers are designed perfectly symmetrically. Both channels have the same electrical components and structure, and equally long signal paths. Thanks to minimize the deviations in stereo presentation. Parallel Push-Pull amplifier design with three-stage inverted Darlington circuitry: In parallel "push-pull" amplification transistors alternately "pushing" and "pulling" current. The work in pairs - one output transistor amplifies the positive half of the curve, while other output transistor amplifies the negative. Push-pull amplification is highly effective, but may be affected by occasional distortions. For the case are then three-stage inverted Darlington amplifier circuits. Three-stage inverted Darlington circuitry actively working to reduce distortion by utilizing a low negative feedback to maintain stable voltage and maintain transient response. To simplify, it is a very sophisticated technology in collaboration ensures consistent output. Separate Wolfson DAC 192 kHz/24bit for L/R channel: Onkyo A-9070 uses cutting-edge digital analog converters to optimize its performance. With the support of two 24-bit DACs, which support sampling rates up to 192 kHz, you are assured superior listening experience from a relatively cheap CD/DVD players. Although these converters designed for processing two-channel audio, A-9070 uses separate chips for each stereo channel, to ensure the most accurate digital analog conversion - and it can be assured that quality feel out of the box.
