Denon DA-300USB<\/strong> is a digital-to-analog converter and headphone amplifier for listening to a computer or other digital audio sources through headphones or a stereo system. A computer connects to the rear USB Type-B input. Two optical inputs and one coaxial input accommodate other digital sources. Headphone volume is controlled on the DA-300USB, while its analog output has a fixed level.<\/p>\n

Who it is for<\/h2>\n

For headphone listening, use the headphone output and the DA-300USB volume control. For playback through a stereo system, connect the fixed-level analog output to the stereo amplifier and adjust the listening volume there. Knowing which device controls the volume is especially useful when switching between headphones and speakers.<\/p>\n

Connecting a computer<\/h2>\n

The rear USB Type-B input<\/strong> operates asynchronously and provides bit-perfect digital signal transmission. It is the connection for a computer playing PCM or DSD recordings. The stated maximum PCM input resolution over USB is 192 kHz \/ 24-bit. This describes the signal the input accepts; it should not be confused with the rating used to describe the DAC chip.<\/p>\n

DSD 2.8 and DSD 5.6 streams travel through the USB connection using DoP<\/strong>. If your music library includes DSD recordings, take this transmission method into account when choosing playback software. The USB input is intended for computer audio and should not be treated as a phone connection.<\/p>\n

Other digital sources<\/h2>\n

The two optical inputs<\/strong> let you connect two sources with optical digital audio outputs. A coaxial input<\/strong> is available for a third source. Choose the input that matches the output on your source: an optical signal does not connect to the coaxial input. The stated maximum signal resolution for these digital inputs is 192 kHz \/ 24-bit.<\/p>\n

Both optical connections and the coaxial connection are inputs<\/strong>. They receive audio from a player or another source. If your system needs to send a digital signal from the DA-300USB to another device, these connections do not serve that purpose.<\/p>\n

Audio outputs and volume control<\/h2>\n

The fixed-level analog output<\/strong> is intended for equipment that has its own volume control, such as the line input of a stereo amplifier. Before starting playback, turn down the amplifier and then raise its volume gradually. The separate control on the DA-300USB adjusts the headphone output. It does not change the level of the analog output, so use the amplifier to set the volume when listening through a connected stereo system.<\/p>\n

The specified headphone amplifier power is 50 mW into 32 ohms<\/strong>. That figure describes a measurement condition for the power rating. By itself, it does not tell you how loud every pair of headphones will play or establish suitability from headphone impedance alone.<\/p>\n

Placement and construction<\/h2>\n

The DA-300USB can be placed vertically<\/strong> when that suits your equipment layout. Allow access to the computer connection and whichever digital inputs you use on the rear. The low-noise OELD display<\/strong> and headphone volume control remain at the front for everyday use.<\/p>\n

Inside is the PCM1795<\/strong> DAC chip, which Denon describes as a 192 kHz \/ 32-bit chip. That is a characteristic of the chip; the stated maximum resolution accepted by the USB and other digital inputs is 192 kHz \/ 24-bit. The DA-300USB also uses Advanced AL32 Processing<\/strong> and DAC Master Clock Design<\/strong>. Denon lists high-grade audio components and components customised for this model.<\/p>\n

FAQ<\/h2>\n

How do I connect it to a stereo amplifier?<\/h3>\n

Connect the fixed-level analog output to a line input on the amplifier. Set the listening volume with the amplifier, and turn it down before playing music for the first time.<\/p>\n

Can I use it with a home cinema receiver?<\/h3>\n

Yes, if the receiver has a suitable analog line input. The DA-300USB receives digital audio from your selected source; the receiver then controls the volume and subsequent playback.<\/p>\n

Which connection should I use for a computer?<\/h3>\n

Use the rear USB Type-B input. It offers asynchronous operation and carries DSD streams using DoP. The optical and coaxial inputs are for other digital sources.<\/p>\n

Does the headphone control change the analog output volume?<\/h3>\n

No. The analog output has a fixed level, so adjust the connected system’s volume on its amplifier. The DA-300USB volume control is for the headphone output.<\/p>\n

Does the chip’s 32-bit rating mean the USB input accepts 32-bit audio?<\/h3>\n

No. Denon describes the PCM1795 as a 192 kHz \/ 32-bit chip, but the stated maximum USB input resolution is 192 kHz \/ 24-bit.<\/p>\n

Can the optical connections output audio?<\/h3>\n

No. Both optical connections receive signals from sources. The coaxial connection is also an input; the analog output carries audio to a connected system.<\/p>\n

How many digital sources can I connect?<\/h3>\n

You can connect a computer to USB Type-B and three more sources: two to the optical inputs and one to the coaxial input. Select the input for the source you want to hear.<\/p>\n","protected":false},"excerpt":{"rendered":"
