Denon AVP-A1HDCI Ultra Reference A/V Network Streaming Preamplifier

Denon presents the ultimate A/V surround sound and video processor — the AVPA1HDCI. With features and capabilities simply not found on any other controller, the AVPA1HDCI sets the standard for both audio and video processing ability, along with state-of-the-art next-generation digital media connectivity with built-in Ethernet and Wi-Fi (802.11b/g) that lets you access music and photo files as well as Internet radio stations. (See "Spec sheet" link for Denon's complete list of specs).

Your State-of-the-Art Denon Solution for Maximizing Content Quality The great appeal of a home theater is to be surrounded by dynamic, realistic sound and stunningly beautiful video images. In this age of high-quality 1080p video and high-definition audio, the core of Denon A/V surround sound technology has been the Dynamic Discrete Surround Circuit (D.D.S.C.). Now, with the AVP-A1HDCI, Denon has developed the D.D.S.C.-HD circuit so that high-quality HD audio performance is on par with the high quality of video images. This new circuit masterfully embodies Denon’s foremost design concept for A/V surround amps which is to "reproduce content with total fidelity to the original intent of the producer." The D.D.S.C.-HD reproduces with ideal quality the sound of the latest high-grade HD audio sources. The "simple and straight" design concept of the AVP-A1HDCI 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 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. 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. 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. Directmounting 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.
