High-Resolution Audio Dual DAC Differential Circuitry:

  • The DRA-800H is equipped with two AKM 32-bit D/A converters featuring high-resolution audio decoding with multiple lossless file types.
  • This premium DAC from AKM 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).
  • Play them from memory devices via the front-panel USB or over network sources.
  • The DRA-800H also supports low-res compressed music file types, such as MP3 and WMA. Thanks to its dual DAC differential circuit, the DR-A800H lets you enjoy superb audio fidelity from all your favorite audio tracks.

Listening Modes:

  • In addition to stereo playback, the Denon DRA-800H 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.

Note: The DR-A800H is not compatible with Dolby Digital, DTS, or other multichannel surround formats.

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-800H 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.

Note: This receiver does not offer auto speaker calibration and room correction.

Tone & Balance Control:

  • The Denon DRA-800H 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-800H stereo receiver offers the following volume & level settings.

Volume Settings:

  • You can choose to display an Absolute volume scale (0-98) or Relative volume scale (-79.5 to 18dB). You can also set a maximum volume level of 0 (80), -10 (70), or -20 (60) dB to limit the receiver's total volume output.
  • In addition, you can define the volume setting that is active when the power is turned on; select "Mute", -79 to +18dB (1-98), or Last. Volume settings can be adjusted independently for the Main Zone and Zone 2.

Mute Level:

  • You can set the amount of attenuation for the audio muting circuit; -40dB or -20dB below current volume, or full mute (sound turned off entirely).

Source Level:

  • This function adjusts the playback level of the currently selected input source's audio input.
  • Use this feature if there are differences in the input volume levels between different sources. You can correct the playback level of the audio input from -12 to +12dB.
