Circuitry adjusts the gain so that less than half the amount of attenuation no interference and maximum efficiency The Advanced Onkyo Microfiber is necessary The signal never comes close to the noise floor and thereby A OMF diaphragm woofer is made from a three layer construction that absorbs eliminates the possibility of noise contamination that plagues conventional volume vibrations that can adversely affect the quality of the emitted sound This thin attenuation methods yet rigid diaphragm enables an extremely fast and accurate response essential or the reproduction of quality audio Also a V Line Edge on the suspension Discrete Output Stage Circuitry suppresses any extraneous vibrations that can cause the sound to deteriorate It is all too common for manufacturers of mini systems to employ just one circuit significantly Capping it off an Aero Acoustic Drive slit duct has been included at the output stage With multiple transistors crammed onto this single circuit o reproduce a sound that is both responsive and spacious it its delivery excess heat is generated and the audio signal is compromised The CS 420 is different It uses discrete amplifier technology similar to that found on our high end receivers Keeping the transistors separate at the output stage enhances cooling so the CS 420 s longevity is extended and interference to the audio signal is reduced C5420 CD RECEIVER SYSTEM CR B8 CD Receiver Amplifier Featu
