Circle Surround generates surround sound from any audio source such as CDs, MP3s, WMA files and radio broadcasts with just four speakers. Focus raises the stereo soundfield, making the sound appear to be coming from directly in front at ear level. Its use complements surround sound to create a rich, enveloping soundfield. TruBass is technology based on psychoacoustics and scientific knowledge of the human hearing system to generate bass sounds extending lower than a small speaker’s response so that a subwoofer is not required. Focus Generates virtual speakers that create a front-firing, higher-positioned soundfield. TruBass Generates a virtual subwoofer for satisfying low frequency reinforcement. Circle Surround Multichannel surround sound is generated from any audio source. CD8455 (Pro off), CD8445 (Adv. on) High voltage and low impedance output High-end audio products usually are engineered to have preamp outputs that have high voltages along with low impedances. These characteristics are desirable from an audio electronics point of view as they enable driving downstream amplifiers optimally to reap other benefits such as a higher signal-to-noise ratio and increased dynamics. Each CD receiver ensures any connected external amplifier will deliver optimal performance. CD8455/8445: 8V at 55. CD5435/5425/5415/5405: 5V at 55. Advanced 24-bit .. D/A converter Digital circuits benefit from signals staying in the digital domain as long as possible, helping to minimize distortion and noise. All signal processing in the CD Receivers remains entirely in the digital domain until the last stage prior to power amplification. The final level of audio performance also relies on high- performance digital to analog conversion. As this process greatly influences final sound quality, a proprietary DAC is utilized so distortion is minimized and S/N ratio stays high. Analog AM/FM signal is sent to a A/D converter before entering the DSP. CD CD-R/RW MP3 WMA ATRAC3 DSP AMP SP D/A converter DigitalDigital AnalogAnalog Conversion CD8455/8445 High-performance DSP Featured in the CD8455 and CD8445, this single sophisticated chip contains the Parametric EQ, Multi-Harmonizer, Time Alignment and Crossover functions as well as level. Parametric EQ This sophisticated equalization method is the best for achieving a smooth, well-balanced in- car system frequency response that overcomes the frequency peaks and dips often encountered in automobile environments due to the combination of hard, reflective surfaces and soft, absorbing surfaces. Parametric EQ allows selecting a frequency band as well as bandwidth for an even system response. CD8455, CD8445 (Adv. on) 3-band Graphic EQ An additional EQ method to adjust the tonal characteristics of program material to suit user preferences. CD5435/5425/5415/5405 Time Alignment Electronic delay lines make sure the sounds from all the speaker units arrive at the listener’s ears simultaneously for a much more natural sound with improved imaging. CD8455, CD8445 (Adv. on) Crossover To create a smoother system response in a multi speaker system, the frequency point and slope can be tweaked for each speaker. CD8455/8445/5435/5425 Multi-Harmonizer Digital music files in formats such as MP3, WMA and ATRAC3 lose harmonic data during encoding because compression is applied. Multi-Harmonizer restores the lost harmonic data, allowing files to sound much better. Original music file Lost harmonic data MP3 file Restored harmonic data CD8455/8445 MOSFET 50W . 4 power amplification MOSFET devices are used for power amplification due to their desirable characteristics — drawing less current and requiring less power — as well as providing a more natural sound. All Units AUX Input When connecting external sources, the AUX input has adjustable sensitivity for perfect matching to cut extraneous noise and improve S/N ratios.
