Blackmagic Design HDL-AUDMON1RU overview

  • 1Description

The Blackmagic Design Audio Monitor provides 2-channel audio monitoring of AES/EBU digital audio, audio embedded in SDI and analog audio. Designed to provide you with peace of mind, the unit provides high-quality audio monitoring of signals from decks, video servers, and live transmissions. You can use the unit to check audio levels as you work on your project. Up front and big on the unit's front panel are two 27-segment LED VU meters that provide you with a bright, visual representation of the audio levels from -45 to +3 decibels, and two built-in, full-range stereo speakers provide clear audio. Control of the unit is by a front panel illuminated keypad that allows you to select input sources to monitor. A 2.1" LCD screen for viewing input video (up to 4K), and a headphone jack and headphone volume control for when the listening environment is too intrusive

Supporting video resolutions up to Ultra HD, the audio monitor allows you to monitor the embedded audio as separate stereo pairs, before passing the signal out through either the SDI loop through port with 16-channel embedded audio or the HDMI 4K connector with embedded 2-channel audio. The rugged aluminum case features a card slot for an available Dolby Decoder card, allowing you an easy upgrade path. The 1RU-sized unit comes with a class A/B amplifier for a balance between high fidelity and power efficiency, dual subwoofer design with extra wide range speakers allow you to sit back and hear the audio. Rackmount ears are built-in for use in a post facility or mounting in a production case.

Audio Inputs

The Blackmagic Design Audio Monitor supports audio from a variety of sources, AES/EBU digital audio, balanced and unbalanced analog audio, as well as audio embedded in the SDI stream. You can monitor 2 channels of audio at a time, and even select stereo pairs from the 16 channels in the SDI signal.

Audio Output

SDI loop through supports 16-channel embedded audio, and the unit outputs 2 channels of embedded audio in the HDMI output stream.

Front Panel Control and Features

The 2-channel audio meters are selectable between VU and PPM, and show a range of -45 to +3 dB in 27 steps. The audio level meter brightness is adjustable so the meters are easy to read in either bright or dark environments.
An illuminated keypad on the front panel, allows you to select audio inputs, isolate left and right audio channels, mute, and select audio channels to monitor from within the SDI stream.
The scroll wheel works as a volume control knob.


Two full-range speakers and two subwoofers combine to provide audio that is rich in low frequency and provides sharpness in mid and high ranges.

Video Support

When you are working with SDI video input you can use the Blackmagic Audio Monitor to convert from SDI to HDMI for monitoring with big screen televisions or video projectors. The unit automatically switches between SD, HD, and even Ultra HD 4K. You can monitor in high resolution Ultra HD 4K using the HDMI 4K output with only a single HDMI cable or you can connect a regular HDTV and use the unit's built-in Ultra HD 4K to HD down conversion.
You can also monitor video on the built-in 2.1" LCD panel, which displays video format, audio type, audio channels and volume level.


The Audio Monitor features an internal dedicated Dolby slot so you can add an available Dolby decoder module. The Dolby decoder supports Dolby Digital and AC-3 decoding for 5.1 surround sound monitoring from either the 6G-SDI video input or the AES/EBU audio input

Rackmount Design

The 1RU height of the Audio Monitor makes it ideal for use in either a post production rack system, location production case, or control or mixing room. The built-in rack mount ears make for hassle free mounting into available standard rack systems.
The Audio Monitor features an internal power supply, and runs off of 110-240 V AC at 50/60 Hz.

    Blackmagic Design HDL-AUDMON1RU reviews

    Audio Monitor is rated 2.9 out of 5 by 7.
    Rated 1 out of 5 by from Nice box, bad volume. Out of the box I was expecting good things from this unit, the build quality looks solid and it has some weight signifying good speakers and amps. Unfortunately, its nearly impossible to hear in a noisy equipment room. I thought the first one I got was defective (since the right speaker did not work) but the RMA unit, while both channels worked, was no louder than the first one. At 100% volume in a typically noisy rack room, it was barely audible beyond a few feet.

    Rated 1 out of 5 by from Poor Sound As the other review says, the sound is poor...surprinslgy poor. I have some fostex RM-1 units that put out a lot of sound. I figured this would be equavallent but it wasn't even close. You can barely hear anything at full blast in a somewhat quiet room and the clarity is poor. Great idea, bad execution.

    Rated 5 out of 5 by from Great product will purchase again. We use this producing a Televison show for the Word Network. I think the sound was great. Better then the speakers we had before. I am not an audio engineer. I am just a producer. We bought an ATEM Blackmagic switcher as well as some BM Studio cameras. So I took a chance with this unit. I have heard no complaints from anyone working with it. The sound is excellent. I can ouput to another TV monitor with ease. I think it suits us just fine. It may not be for everyone since the TV world is so vast. But for the proce, I think it is a great value.

    Rated 3 out of 5 by from Great features, quiet speakers We use this unit inside our production truck and the meters and connectivity are great but the volume of the speakers is too low. I read other comments about this but I didn't think it would be as low as it is. With all the other noise in the truck I can barely hear anything at all. Good thing it has a headphone jack.
    Date published: 2016-05-26
    Rated 2 out of 5 by from headphone jack levels way too low Otherwise it's solid, but we've have had numerous audio engineers in at our show and they all mention how the headphone jack isn't loud enough, even at full volume. Strange oversight, not sure how it made it into production this way.
    Date published: 2018-04-23
    Rated 3 out of 5 by from Bad speakers / Great visual VU's The speakers and the headphone jack are extremely low I had to add external powered speakers for it. However the VU's on the front are bright and beautiful and can be seen anywhere in the room.

    Rated 5 out of 5 by from great piece of kit I use this all the time, even in my edit studio when I'm not on the road. The sound quality is excellent.
