NEW MODEL INFORMATION
AVR-87
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.
