CY-1ET6525SA-08 8-Channel Surround Digital Amplifier
CY-1ET6525SA-08 8-Channel Surround Digital Amplifier
HOT!NEW!
CY-1ET6525SA-08 is a high-powered eight-channel digital amplifier in our regular series, capable of driving high performance multi-channel loudspeakers with demanding power requirements in a surrounding system. Powered by 8 pcs of Purifi Audio's 1ET6525SA modules, the successor to 1ET400A, this amplifier delivers extraordinary musical performance with its superb detail, resolution and soundstage, as well as ultra-low noise distortion and extremely fast transient response. To get the most out of the 1ET6525SA's capabilities, our custom-designed BB-TI4733D-3F buffer board features the high quality TI TPS7A4700/3301 low dropout regulators, eliminating any unnecessary noise and interference before the power reaches the Op amps of this buffer board, thus supplying stable power to the module. In addition to adapting to most of the popular Op amps in the market, it can also be configured with other audiophile-grade Op amps, making the sound richer, denser and more delicate while adding warmth and depth. Benefiting from the continuous innovation of digital amplifier technologies over the years, our latest generation of amplifiers not only retains the unique sound characteristics, high efficiency power and lightweight size of previous digital amplifiers, but also provides sound quality comparable to traditional amplifiers on the market that are several times more expensive, whether it is Class-A, Class-AB and even other Class-D types.
To acheive the best possible sound from the CY-1ET6525SA-08, the quality of the power supply to the buffer board is one of the key factor. After continuous research and testing on the power supply by our R&D team, the following three requirements must be met in order to bring its performance to the next level: first, the power must be stable; second, the power must be sufficient; third, the power must be pure. The first requirement has been fully accomplished by adapting discrete voltage regulators with the most powerful noise reduction capabilities, while the remaining two requirements are fulfilled by using our specially designed LPS-AUX08C-3H auxiliary linear power supply module. With three sets of internal power supplies, it independently powers the buffer board of each channel to secure that the Op amps of each channel obtain the most sufficient current supply. To ensure that the Op amps draw the purest and cleanest power in the entire power chain, each set of power supplies uses an audiophile-quality linear power supply to power the buffer board, which perfectly complements its discrete voltage regulators, bringing its power quality closer to perfection. In addition, a variety of efficient power management functions are also implemented, including the ability to control the power state of the main power supply and support for 12V trigger control switch functions. As for the main power, this amplifier in the Regular Series is supplied by a Hypex SMPS3KA400 switching power supply, which fully utilizes the potential of 1ET6525SA.
In the standard configuration of our regular series, each buffer board comes with the very popular TI OPA1612 dual Op amps and all connectors are equipped with our carefully selected high quality components. Benefiting from internal structure of the modular configuration, Op amps can be replaced with TI 's higher-grade Muses 02 or audiophile-grade Sparkos Labs SS3602 full-discrete Class-A dual Op amps upon customers request. Not just limited to Op amps, customers can also choose to upgrade other components before shipment, including power IEC inlet, speaker post and other accessories. In addition, each set of 1ET6525SA modules is equipped with a highly efficient heat sink, which solves the heat dissipation problem in a densely packed multi-channel chassis environment. As surround sound technology continues to evolve, each input channel is equipped with 2 sets of input switching function in order to ensure that this amplifier can serve customers' surround sound systems for years or even decades. With this capability, customers can add another latest generation surround preamplifiers/processors with more powerful DSP capabilities at any time. Therefore, enjoying the latest immersive and realistic surround sound formats from Dolby, DTS, Auro-3D, etc. while maintaining the same sound quality is no longer a difficult task. Lastly, all of our amplifiers also employ a new symmetrical internal and rear panel layout to keep the internal wiring as short as possible.
