State-of-the-art Denon Solutions for
Maximizing Content Quality
All new circuit layouts that shorten audio and video signal paths for best
picture and sound
The "simple and straight" design concept has been thoroughly implemented
in the signal paths to contribute to immaculately clean audio and video playback.
Signal paths are as short as possible to keep signal degradation in the audio and
video circuitry to an absolute minimum.
Fully separated Audio, Video, Pre-Amplifiers and Power Supplies allow for a
cleaner and clearer signal path
Dedicated transformers have been allotted for each block to prevent
unwanted noise and produce a clean power supply circuit. One large toroidal
transformer is used for the XLR output circuit and a second large toroidal trans-
former powers the analog audio circuit. Two transformers are used for the ana-
log video circuitry; dedicated power supplies are provided for the display, CPU,
digital audio circuitry, and digital video circuitry; and two are for the pre-amp
section. The combination of these transformers, 50-ampere bridged diodes,
four 10,000 microfarad block capacitors, and an ultra-robust power supply
provides a stable source of power.
Pre-amp, amplifier, and volume control in discrete configuration as a single
component
The AVP houses a low-impedance drive pre-amp, amplifier, and volume control unit
in a discrete configuration as a single component. Since circuits configured of op-amps
or similar devices used in general amplifiers do not have drive capability to withstand
low impedance, distortion occurs under large current. This discretely configured
pre-amp is capable of delivering distortion-free output thanks to its class-A operation
capability up to low impedance. This circuit also requires a small number of elements,
allowing output of pure audio signals of high S/N ratios and low distortion.
Direct Mechanical Ground
Vibration-resistant construction has been reviewed to thoroughly suppress the
adverse influences of vibration on sound quality. The power transformers, a source
of vibration, have been securely mounted on the highly rigid bottom chassis. Direct-
mounting of cast-iron feet to the radiator in near proximity to each other serves to
suppress mutual vibration with the power transformers and other sources of vibration.
And careful mounting and placement of various parts has effectively eliminated the
influences of external and internal vibration. This is all part of Denon’s uncompromising
design for impeccable sound quality.
