User manual DENON AVR-684

[. . . ] This combination of DSP and D/A converters works to bring out the tremendous potential of Dolby Digital and dts sound. In addition, high resolution A/D converters have been incorporated for the Dolby Pro Logic decoder. The high sound quality of New DDSC-Digital is due in part to the high-grade signal processing of the 24-bit, 96-kHz Digital Interface Receiver (DIR). The AVR-3300 not only allows digital signals input from DVD and other advanced media to pass directly to the DIR, it also processes them while preserving their integrity so that even the most delicate nuances of the music, reflecting the emotions of the artists, are passed unfettered to the dual digital signal processor (DSP). Dynamic Discrete Surround Circuit-Digital Block Diagram s Dolby Digital Dolby Digital and Dolby Pro Logic decoding functions are performed in the digital domain for excellent dynamic range and crystal clear reproduction.

This construction reduces noise interference among the circuits and ensures a clean, transparent sound. s Hefty Power Transformer for Stable Supply of Power A power transformer has been connected in the power section where it is combined with a rectifier diode and a large block capacitor to ensure a large, stable supply of electrical current. Accordingly, the AVR-684 boasts high output power of 100 W for each of the 5 channels. s Stable Speaker Drive In the AVR-684, the circuitry through which current flows to drive the speakers has been incorporated onto a single board between the rectifier circuit of the power source and the speaker terminals. A new phase correction circuit has also been adopted, eliminating the need for an output coil. Since this configuration allows the power transistor to drive the speakers directly, there is no loss of power to any of the channels. The sound that you hear is thus extremely stable as well as powerful. DVD, VDP, TV/DBS, VCR-1, VCR-2/V-AUX 5 Composite Inputs . . . . . . . . . . . . .
