| AVR-87 |
NEW MODEL INFORMATION | Dolby Digital and DTS A/V Receiver |
Eminently Affordable, High-Quality Ambiance For Your Home Theater.
The AVR-87 is an A/V surround receiver that lets you enjoy Dolby Digital and dts surround sound with maximum ease. To ensure that all channels deliver an identical response—a vital requirement of both Dolby Digital and dts—the AVR-87 is equipped with fully discrete, equal power amplifiers. Sound effects linked with the action in a movie will thus move in the listening space around you and greatly heighten the sense of realism.
The remote controller that comes with the AVR-87 is equipped with an LCD that displays up to 10 characters of text. This lets you easily make settings for System Call and Preset Memory following the prompts.
■Fully Discrete, Equal Response and Power of 75 W for Each Channel
Front | 90 W + 90 W (8 ohms, 1 kHz, 0.07% THD) |
Center | 90 W | (8 ohms, 1 kHz, 0.07% THD) |
Surround | 90 W + 90 W (8 ohms, 1 kHz, 0.07% THD) |
The AVR-87 uses a high-capacity power transformer in the power circuit to support not only stable reproduction of 5.1- channel Dolby Digital / dts sound sources but also high-quali- ty pure audio recordings. The fully discrete configuration of the power amp section delivers equal power to the Front Left and Right, Center, and Surround (Rear) Left and Right speakers to ensure that they all respond at identical levels. During surround sound reproduction, the AVR-87 taps its powerful reserves of 75 W for each of the 5 channels to sur- round you with a refreshingly clean, realistic sound.
■DDSC-Digital (Dynamic Discrete Surround Circuit-Digital)
Since surround signals are all processed in the digital
domain, the AVR-87 is equipped with a newly-developed, sophisticated, high-performance DSP circuit for the Dolby Digital, Dolby Pro Logic, dts decoders, and Surround Simulator. The D/A converters feature high resolution designs for all the Front L/R, Center, Surround L/R, and Subwoofer channels. This combination of DSP and D/A converters works to bring out the tremendous potential of Dolby Digital and dts sound. In addi- tion, 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-87 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 deli- cate nuances of the music, reflecting the emotions of the artists, are passed unfettered to the digital signal processor (DSP).
