Denon AVR-87 - Manual

■ 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).

NEW MODEL INFORMATION
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.
