State-of-the-art Denon Solutions for

Maximising 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 unwant-

ed noise and produce a clean power supply circuit. One large toroidal trans-

former is used for the XLR output circuit and a second large toroidal transformer

powers the analog audio circuit. Two transformers are used for the analog 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 con-

figured 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 vibra-

tion. 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 uncom-

promising design for impeccable sound quality.
