DAC + Headphone Amp: Denon's DA-300USB combination D/A converter and
headphone amplifier elevates your computer-sourced digital audio tracks and
other digital music sources to purist audiophile levels, delivering superb sound
quality without compromise. Equipped with a range of advanced digital
technologies, the DA-300USB connects via asynchronous USB to the computer and
features the ability to decode both PCM (traditional digital audio format) and
DSD (Direct Stream Digital; the advanced digital audio format of SACD). It also
has SPDIF (coaxial/optical) inputs for upgrading the sound of your HDTV, disc
player, or game console. The DA-300USB is fitted with an analog line-level
output and headphone amplifier for connection to your home entertainment system
or high-quality headphones.
32-Bit/192kHz DAC: At the heart of the Denon DA-300USB is the high
resolution PCM1795 D/A converter, which features advanced segment 32-bit
architecture along with the ability to handle up to 192kHz PCM sample rates as
well as the ability to decode both 2.8Mhz and 5.6Mhz high resolution DSD files
(either natively decoded or via DoP - DSD over PCM).
Advanced AL32 Processing: For the widest dynamic range and lowest
distortion, the DA-300USB features sophisticated digital signal processing,
including Denon's exclusive Advanced AL32 processor that delivers vastly
improved detail especially through the critical midrange band, providing
noticeable improvements in clarity with low level softer sounds.
Asynchronous USB Port: Via its USB (type-B) port, the DA-300USB
communicates with your Windows or Mac computer via asynchronous data transfer
mode, which ensures smooth, jitter-free digital communication, which is
especially vital with very high bandwidth digital audio data-streams. The
asynchronous USB (type-B) port connects to your computer's USB (type-A) port.
Once connected, the computer recognizes the DA-300USB and routes the digital
audio data to it, bypassing the source device's internal audio circuitry. For
optimum compatibility with the broadest range of sampling frequencies, the
DA-300USB is equipped with two master clock crystals (44.1/48kHz), instead of the usual one.
- Windows PC: Compatible with Windows XP (SP3), Windows Vista,
Windows 7, and Windows 8. Your Windows PC will require a separate
USB Audio Driver which can be installed from Denon's website.
- Mac Computer: Compatible with Mac OS 10.6.3 or later. No
additional driver required.
Note: To prevent audio quality from degrading due to noise from external
devices when this unit is connected to external devices such as computers, the
ground circuit for the USB input interface device is isolated from the audio
Compatible Music Formats: Practically any digital audio format that
can be played from your computer's own media player can be processed by the
DA-300USB; including MP3 (up to 48kHz), AAC (up to 48kHz), ALAC (up to 96kHz),
WAV (up to 192kHz), FLAC (up to 192kHz), and DSD (2.8224/5.6448 MHz).
Optical & Coaxial Digital Inputs: For connection to other digital
audio sources other than your computer, the DA-300USB also features three
digital audio inputs; two optical (toslink) and one coaxial (RCA). Now you can
enjoy greatly improved sound quality from your HDTV, satellite or cable box,
game console, or disc player. The optical and coaxial digital inputs will
support digital audio up to 24-bit/192kHz (2ch PCM only).
Analog Outputs: For the purest audiophile grade sound quality, the
DA-300USB is equipped with separate audio output circuits for the analog
line-level outputs and the headphone output.
- Headphone Amp: The headphone amplifier block features dedicated
buffer and gain stages, and is compatible with the widest range of headphone
types, including low-impedance models. The front-panel headphone jack
features a standard-sized 1/4" connector, along with a convenient volume
- Line-Level Outputs: The line-level outputs are high quality
RCA-type connectors, with full 2Vrms output for compatibility with integrated
amplifiers, pre-amplifiers, and other analog audio components.
Audiophile-Grade Construction: The Denon DA-300USB features
construction with the high-quality component parts and circuit design. Housed in
a sleek casing, the DA-300USB features seven separate printed circuit boards, to
ensure the highest isolation between circuit blocks. To ensure the most stable
and accurate digital audio and timing data at the critical D/A converter stage,
the DA-300USB also features advanced isolator chips that combine high speed CMOS
technology with unique on-chip micro air-core transformers. A total of 9
isolator chips are employed, with 18 channels of isolation, delivering superior
common mode noise rejection and maximum protection against digital noise
transfer between critical stages, compared to conventional optoisolators.
Front-Panel Display: The elegant front-panel of the Denon DA-300USB features an
advanced OLED display that provides clear indication of the input selected,
along with the audio file type (PCM, DSD), the sampling frequency and the
headphone volume level. The touch-sensitive controls lets you easily cycle
through the various modes. The display does not indicate track or
song/artist/album information of your music source.
External Power Supply: Powered by a 15V/1A AC adapter, the DA-300USB
features sophisticated DC power conversion technology with a power block that
delivers separate DC voltage sources to power the various stages.
Note: You can set the DA-300USB to automatically switch to "Standby Mode" if the
unit is not operated for 30 minutes when there is no audio input.
Mounting Options: You can choose to mount the DA-300USB either
vertically or horizontally, depending upon your equipment configuration. An
internal sensor detects the chosen orientation, and rotates the OLED display
data accordingly. A custom bottom plate is provided for vertical orientation.
Note: When mounted horizontally, the DA-300USB measures
6.75" (w) x 2.1875" (h) x 8.0625" (d). When mounted vertically, the unit
measures 4.5" (w) x 6.9375" (h) x 8.0625" (d)
