A/V Surround Receiver
AVR-5803
THX Ultra2 Certified A/V Surround Receiver with New Dolby Pro Logic IIx and HDCD Decoder
The AVR-5803 surround receiver inherits the critically acclaimed amplifier design characteristics of the AVR-5800 while adding Denon's much improved DDSC-Digital sound processor for greater diversity in multi-channel reproduction of digital and analog signals. The AVR-5803's objective is to bring out the maximum performance potential of all types of sound sources. This model also provides a video conversion function for greater monitior connection flexibility, the added convenience of variable subwoofer crossover switching, that will ensure a listening environment that is as close to ideal as possible. With its support of THX Ultra2, Dolby Pro Logic IIx, HDCD decoder and a wealth of other features, the AVR-5803 has become Denon's latest “Surround Reference” A/V receiver for serious home theater enthusiasts.

The AVR-5803 features an equal power 7-channel amplifier section, with identical amplifier design on all 7 channels. The Front (L/R), Center, and Surround (L/R) channels are driven by 170 watts of power each, and the two Surround Back channels, used for 6.1-channel DTS-ES and DOLBY DIGITAL EX sources, are also each powered with 170 watts (all channels rated into 8 ohms, 20 Hz - 20 kHz). High current, low impedance drive-capable discrete power transistors are used for each channel, and the high power output of 170 watts per channel (into 8 ohms) ensures that the speakers are driven with ample foundation to reproduce movie and music soundtracks with superb fidelity and the widest dynamic range.
The AVR-5803 proudly bears the THX Ultra2 logo, certifying that it satisfies the newest certification standards of Lucasfilm Ltd., governing performance, features, sound quality, power, stability into low-impedance speaker loads, and ease of operation.
■ Accurate Signal Transmission from the Pre-amplifier Section
Parts suitable for high attenuation have been strictly selected for use in the volume circuit that controls the signal levels of all eight channels. Since a differential D/A configuration has also been adopted for each channel, the widest possible dynamic range is secured with mutual interference effectively suppressed across the entire frequency range. The pre-amp's gain is varied to match the output level, improving S/N in the range where the volume is often used. Highly accurate volume adjustment in variable steps of 0.5 dB in the range of -80 to +15 dB is possible as well.
■ High-quality Pure Audio Chassis Construction
By positioning the power transformer at the center of the unit, the AVR-5803 is equipped with a chassis construction in which unwanted vibrations are suppressed and excess vented heat is minimized. The digital circuits have been placed in the lower center of the unit and are completely shielded in their own enclosure, and the power amp circuits are located on the left and right sides. In addition, the analog circuitry has been isolated from the video circuitry to completely eliminate any mutual interference. The total chassis design preserves the purity of the audio signal from input to output to give your home theater a clean yet powerful sound, alive with all the details of the original recording.
■ Wide-Range Play Capability for DVD-Audio or SACD
■ New DDSC-Digital Processor, for High-quality Sound Reproduction
1. 24-bit, 192-kHz Analog-to-Digital Conversion
The AVR-5803 is capable of 24-bit, 96-kHz or 192-kHz A/D conversion, improving S/N and dynamic range by approximately 10 dB. A/D conversion and DSP processing (*1) of external input signals (max. 8 channels) is also possible. The AVR-5803 is thus able to perform bass management and delay processing on DVD-Audio signals. THX post processing is also possible with this DSP.
(*1). It is possible to select whether signals are to be processed by the DSP or output as an analog signal.
2. 24-bit, 192-kHz Digital Interface Receiver
The AVR-5803 employs a total of four 24-bit, 192-kHz digital interface receivers, one for every two channels, enabling multi-channel digital input through DENON Link or external digital input to perform at optimum potential.
3. New SHARC Dual 32-bit Floating Point DSPs
The AVR-5803 uses a dual configuration of new HammerHead SHARC 21161 32-bit floating point DSPs from Analog Devices.
4. 24 bit, 192 kHz All-channels Differential-mode D/A Conversion
For optimum fidelity and transparency, the AVR-5803 features 16 of the latest Burr-Brown PCM-1738E high resolution 24-bit, 192 kHz DACs, in.an eight channel, differential configuration (2 DAC channels per each audio channel). These DACs feature DSD compatibility.
■DENON’s Latest Surround Technology Faithfully Recreates the Surround Sound Produced at the Dubbing Stage.
DTS-ES Discrete 6.1 / DTS-ES Matrix 6.1 / DTS NEO:6 / DTS 96/24 Dolby Digital / Dolby Digital EX / Dolby Pro Logic II
THX Surround EX / THX Cinema / THX Ultra2 Cinema / THX Music Mode
■ DTS-ES Discrete 6.1 + THX Post Processing
By adding THX Post Processing to the localized sound and spatial expression of DTS-ES Discrete 6.1, your listening room is almost completely transformed into a full-featured cinema.
■ DTS NEO:6
DTS NEO:6 lets you enjoy 2-channel analog, PCM, and Dolby Digital 2-channel sources in full 6.1-channel surround sound.
