Denon DN-300R overview

  • 1Description

The Denon DN-300R is a 1 RU, rack-mountable audio recorder and playback device designed for installed sound applications in houses of worship, music clubs, and more. The unit can record to SD/SDHC/SDXC cards and USB media, either one at a time or simultaneously to both; perfect for capturing conferences or concerts where the client needs a copy of the recording immediately after the event.

The DN-300R features a set of balanced XLR and unbalanced RCA I/O for connecting the input of the unit to an external audio source and its output to powered speakers or a sound system. The unit records WAV files at up to 24-bit / 48 kHz and MP3 files at up to 256 kbps.

Multiple record options are available including mono, stereo, dual mono, and dual stereo. In dual mono and dual stereo modes, two audio files are created with the second one recorded at -10 dB to help protect your recording against accidental peaks in the audio source. Record start can be automatically triggered when the input level passes a certain threshold.

Various playback options enable you to play just a single track or all tracks in a folder or on the device, in repeat or random playback modes. A headphone output with independent level allows you to monitor quietly while recording or playing back.

    Denon DN-300R reviews

    DN-300R Solid-State SD and USB Audio Recorder is rated 4.1 out of 5 by 7.
    Rated 5 out of 5 by from Simple, Reliable Gets the job done. We have been using this to record our church services. We had to adjust the gain of our master, this unit accepts a pretty hot mix. Dual recording option is awesome for giving extra headroom and preventing clipping. Love how easy it was to install in our setup. A++
    Date published: 2018-11-13
    Rated 3 out of 5 by from It is reliable, the quality is good, but it's not perfect. Like most other people say, the input level is low. We are recording speech from a Soundcraft SI series and have the recorder maxed out and the dedicated aux pushed over unity just to get a single LED on the bar graph to light up. That said, the level is perfect right there. Other issue is the timing, it tends to drift in relation to the video that is being simultaneously recorded with a camcorder. Don't know which one is less accurate but the iPhone we used previously drifted less. Typically has to be re-synced about 5 times in a 45 min recording. Have tried various recording settings with no change. It isn't a great way to record but the quality is still leagues better than the iPhone.

    Rated 3 out of 5 by from Easy to use, but record level is low This recorder does everything we need, except that the record level is is very low. We are using the RCA inputs; I don't know if the same problem exists with the XLR inputs.
    Date published: 2018-07-11
    Rated 5 out of 5 by from Great For Recording Church Services We recently added the Denon DN-300R unit to our soundrack to record church services off our Yamaha mixer. We replaced a Gemini unit that was terrible from the start and in five minutes we had the Denon recording on both a SD card and a flash drive. Unlike the Gemini unit the Denon buttons feel solid and the display is very legible. I would recommend the Denon without hesitation!
    Date published: 2018-10-22
    Rated 3 out of 5 by from works as promoted however recorded audio level low However I am trying to record from my bass amp direct out port using a 20 ft cable and the output is weak even with the audio control knob on the DN all the way up. Doesn't seem right. I am going to try a new cable that is 6 ft long and see if that doesn't fix the problem.
    Date published: 2018-05-03
    Rated 5 out of 5 by from Records and plays as advertised It's just what I was looking for. I'm not a pro but wanted to record wav files from my cd and record collection as well as play some digital music that I download. Mission accomplished. This Denon does what I needed at a price I could afford. I find the volume level of the recordings fine. The service was great I'm happy.
    Date published: 2018-10-03
    Rated 5 out of 5 by from Plug and record The unit works great. simple input and plug in flash drive and your ready to record. The input adjustment is important to get the quality recording.
