High Quality 5 x 110 W Discrete Power Amplifier with Easy Operation

DENON's Basic Design for High-Quality Sound Reproduction
• Power Transformer for High Power Driven
The chassis that supports the large transformer has
been designed to absorb vibration, and the transformer
is housed inside a highly rigid frame to secure it more
solidly to the chassis. In addition, a cushioning material
has been placed around the core of the transformer to
minimize interference on the signal and enable more
faithful reproduction of the original sound. DENON's
higher-end models incorporate these low-noise
designs, such as the use of short rings.
• Twin Drive Rectifier
DENON's Twin Drive Rectifier design uses two rectifying diodes in parallel to
bring out the maximum potential of the large transformer. Since the rectifiers
power the large block capacitors at low impedance, they are able to supply
ample current to reproduce deep basses as well as sudden bursts of sound
from percussion or other musical instruments.
• Large Aluminum Extruded Heatsink
DENON uses large heatsink made of extruded aluminum.
They have been placed in a design that ensures mostly
uniform temperatures throughout the heatsink so that
the output transistors for all channels can be driven
under uniform conditions. This in turn ensures that all
channels respond with equal performance to the
demands of the audio signals.

Fully Discrete, Equal Power Five Amplifier Channels, 110 Watts Each
Front
110 W + 110 W (6 ohms, 1 kHz, 0.7 % THD)
Center
110 W
(6 ohms, 1 kHz, 0.7 % THD)
Surround
110 W + 110 W (6 ohms, 1 kHz, 0.7 % THD)
For optimum Dolby Digital and DTS reproduction, the AVR-484 features high
quality, wideband audio amplification, providing 110 watts power
output for each of the five main channels. A large capacity power supply
includes a high current power transformer along with discrete power
output devices on all five amplifier channels for highest dynamic range and
superb reproduction clarity.

Wide-Range Play Capability for DVD-Audio and SACD
The power amp circuits of the AVR-484 have been meticulously designed to
reproduce the exceptionally high sound quality with wide frequency response
from 10 Hz to 100 kHz.
■
Cinema Equalizer
The sound from movie sources recorded in Dolby Digital, DTS or other formats
emphasizes high-frequency range due to a theater’s front speakers being
placed behind the movie screen. If this sound is
reproduced in the home theater without correction, the high-frequency
range is too strong. The AVR-484 features a Cinema Equalizer to correct
these high-frequency components so that the sound is clearer and easier
to listen to. (For Dolby Digital, Dolby Pro Logic II, and DTS surround
modes)
■
Personal Memory Plus, for Easy Operation
The AVR-484 includes the Personal Memory Plus function that
automatically remembers the surround mode you last used for each
program source, so that you do not need to select the mode again for that pro-
gram.
■
Acclaimed Customization Feature
As with all of DENON’s high-grade A/V receiver, the AVR-484 lets you
adjust delay times and other parameters so that you can customize the
performance of the AVR-484 to suit your own home theater and enhance
operating ease. The adjustments are easy to make via a dialog format on the
fluorescent display on the front panel. These customized features are then
stored, for each source input and surround mode, in Personal Memory Plus
so constant readjustments are not required.
