High-Performance Discrete 2-Channel Amplifier: The Denon DRA-900H stereo network receiver features a custom, discrete high-current power amplifier with symmetrical design and an OFC (oxygen-free copper) winding power transformer. The DRA-900H delivers a 100 watts x 2 channels (into 8-ohms @ 20Hz-20kHz with 08% THD). With low impedance drive capability, it offers greater stability with a wide range of floorstanding and bookshelf loudspeakers for balanced, quality sound.

Experts Sound Engineering: Denon sound engineers use carefully selected HiFi parts, including custom resistors and audio grade capacitors, to tune the stereo receiver. Using the design principles found in Denon award-winning amplifiers, the DRA-900H features a symmetrical layout, double differential DAC circuit and analog preamp circuits that don't interfere with the power supply. The dedicated circuitry with its short, straight paths between the power supply, signal and amplification ensure your loudspeakers drive detailed and precise imaging.

High-Resolution Audio Dual DAC Differential Circuitry: The DRA-900H is equipped with two 32-bit/192kHz digital-to-analog converters (DACs) featuring high-resolution audio decoding with multiple lossless file types. This premium DAC delivers amazing stereo imaging and detail. By assigning two DACs per channel including, you'll hear increased dynamic range and improved signal-to-noise. Compatible high resolution music file types include ALAC, FLAC and WAV at up to 24-bit/196kHz. It's also compatible with 2.8/5.6-MHz DSD files (DSD is the audio coding format of SACD). The DRA-900H also supports low-res compressed music file types, such as MP3 and WMA. Thanks to its dual DAC differential circuit, the DRA-900H lets you enjoy superb audio fidelity from all your favorite digital audio tracks.

Listening Modes: In addition to stereo playback, the Denon DRA-900H offers two Direct Listening Modes which bypass the receiver's tone & DSP processing for higher sound quality performance.

• Stereo: Sound is output from the front left and right speakers, as well as the powered subwoofer, with digital signal processing and tone control.
• Direct: Direct Mode provides playback of 2ch audio in its original form, without any digital signal processing or tone control.
• Pure Direct: Pure Direct Mode goes a step further by turning off the receiver's DSP, tone control, display and analog video circuitry to minimize the possibility of any noise being added to the audio signal.

Compressed Audio Restorer: Compressed audio formats such as MP3, WMA (Windows Media Audio), and MPEG-4 AAC reduce the amount of data by eliminating signal components that are hard for the human ear to hear. The Restorer function generates the signals eliminated upon compression, restoring the sound to conditions near those of the original sound before compression. It also corrects the sense of volume of the bass to obtain richer sound with compressed audio signals.

Speaker Setup: The Denon DRA-900H provides a Test Tone to help you setup the output level of your connected loudspeakers. While listening to the Test Tone, you can adjust the output level (-12 to +12dB) of the left and right speakers. You can also adjust the receiver's subwoofer output level (-12 to + 12dB); as well as the the subwoofer output's Low Pass Filter (40, 60, 80, 90, 100, 110, 120, 150, 200, or 250Hz). In addition, you can set the distance (0 to 60') between the speakers and subwoofer from your main listening position.

Tone Controls: The Denon DRA-900H offers Bass & Treble control, along with balance adjustment. You'll be able to adjust Bass & Treble from -6dB to +6DB, as well as adjust the balance in sound output between the connected left and right speakers.

Volume & Level Settings: The Denon DRA-900H stereo receiver offers the following volume & level settings.

Three HDMI inputs (HDMI 4-5-6) and the HDMI output also support 8K (7680 x 4320) video @ 60 frames per second, as well as 4K video @ 120 frames per second (both up to 40Gbps). In addition, the receiver will pass 1080p/i, 720p, and 480p/i video signals via HDMI.
• HDCP 2.3 Compliant: All of the stereo receiver's HDMI inputs and outputs support HDCP 2.3, which fully complies with the latest copyright protection standard for 4K/HDR video transmission.
• 4:4:4 Color Subsampling: The HDMI inputs and monitor outputs support RGB, YCbCr 4:4:4, YCbCr 4:2:2, and YCbCr 4:2:0 color subsampling (pixel depth and frame rate will vary). With 4:4:4 color subsampling, luminance (brightness) and chroma (color) are sampled at the same rate; resulting in an RGB color palette as big as the video sampling rate for a video image with more colors, plus greater color accuracy and detail.
• Wide Color Gamut (BT.2020): The BT.2020 color standard delivers a much wider color gamut and represents about 75% of the total visual color spectrum, while the current Rec. 709 color standard selected as the color space for HDTVs and early generation 4K Ultra HDTVs covers only 35% of the total visual color spectrum.

Dynamic HDR: HDR provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. HDR reproduces a greater dynamic range of luminosity or brightness levels, creating greater contrast. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth. Dynamic HDR enables a noticeable progression in overall video image quality from SDR to static HDR, and now static HDR to dynamic HDR. Dynamic HDR support ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast, and wider color gamuts on a scene-by-scene or even a frame-by-frame basis. Dynamic HDR enhanced content is available for movies, videos, TV shows, video and PC games and VR.

• HDR10: HDR10 is an open standard and currently the most popular HDR format on the market. It uses static metadata at the start of a movie to tell the receiver and your TV that the video content is encoded using HDR.
• HDR10+: HDR10+ is a new open standard that leverages dynamic metadata to produce enhanced contrast and colors on an expanded range of televisions. HDR10+ incorporates dynamic metadata that allows the adjustment of brightness levels on a scene-by-scene or even frame-by-frame basis. By applying individualized tone mapping to each scene, HDR10+ delivers an incredible viewing experience. The picture quality offers an enhanced visual experience with more detailed expressions, brighter shadow areas and more accurate color renderings that stay true to the creator's original intent.
• Hybrid-Log Gamma: HLG (Hybrid-Log Gamma) is primarily designed for live video feed and over-the-air broadcasts. It uses no pre-encoded metadata and is backwards compatible with SDR. HLG's native compatibility allows much of today's existing SDR infrastructure to be re-used for HDR in the future.
• Dolby Vision: Unlike HDR 10 which contains static metadata and HLG which uses no metadata, Dolby Vision uses dynamic metadata technology which sets individual color and brightness levels for each and every scene. Dolby works directly with filmmakers at major Hollywood studios to create superior HDR video masters of blockbuster movies.

4K/8K HDMI Video Upscaling: The Denon stereo receiver offers HDMI video upscaling (up to 4K or 8K Ultra HD) thanks to its NatureVue video processor by Analog Devices. This sophisticated video processor provides upscaling of 1080p high definition HDMI connected sources to 4K or 8K Ultra HD; as well as 4K Video sources to 8K picture quality.

Optimized Gaming: Showcased in the DRA-900H are new HDMI features like Variable Refresh Rate (VRR), Quick Frame Transport (QFT), and Auto Low Latency Mode (ALLM) - which reduce or eliminate lag and frame tearing to offer a smoother, lag-free gaming experience.

• Variable Refresh Rate (VRR): Support for Variable Refresh Rate (VRR) allows the TV to adapt to certain Game console's frame rate. This helps to reduce or eliminate lag, stutter and frame tearing for more fluid and better detailed gameplay.
• Auto Low Latency Mode (ALLM): The receiver will enter ALLM (Auto Low Latency Mode) when it detects a gaming signal from a compatible device (such as a Xbox One) and allows for a smooth, lag-free gaming experience. During ALLM, the receiver disables the i/p scaler and Auto Lip Sync function.
• Quick Frame Transport (QFT): Quick Frame Transport (QFT) transmits each frame at a higher rate to decrease "display latency", which is the amount of time between a frame being ready for transmission in the GPU and that frame being completely displayed. Enjoy reduced latency for smoother, tear-free entertainment experience.
