Audio

The new CD Receiver line delivers outstanding audio performance across the board for each model.

Circle Surround II

This technology enhances in-car listening enjoyment with a powerful combination of three functions. 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.

Circle Surround Multichannel surround sound is generated from any audio source.

TruBass

Generates a virtual subwoofer for satisfying low frequency reinforcement.

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.

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.

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.

3-band Graphic EQ

An additional EQ method to adjust the tonal characteristics of program material to suit user preferences.

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.

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.

AUX Input

When connecting external sources, the AUX input has adjustable sensitivity for perfect matching to cut extraneous noise and improve S/N ratios.
