    Does the "Blackbird 4K HDMI Audio Extractor, 18Gbps, HDCP 2.2" Product#24278 support down mixing 7.1 surround, Dolby TrueHD , DTS-HD, or other HD audio formats to Stereo, or will there just be no sound with the 2CH setting when such a source is used?
    Scott H on Aug 7, 2017
    BEST ANSWER: There will be no sound.
    Question related to Blackbird 4K HDMI audio extractor (#24278). The switch in the Input section has three options TV, Bitstream and 2-CH. If I understand correctly setting to Bitstream, simply passes the bitstream to the output. Does setting to 2-CH decode the bit stream to 2 channels and sends to output ? What does setting to TV mean ? Thanks in advance for the answers
    Shivakumar G on Dec 31, 2017
    BEST ANSWER: From the manual: "TV/Bitstream/2CH Switch: Allows selection of the audio format. The TV option sets the audio output to that of the connected display. The Bitstream option passes the audio output from the video source device and the 2CH option sets audio to 2-channel stereo." There's no mention of up or down conversion; just straight pass-through.
    Is this unit compatible with Dolby Digital Plus?
    A shopper on Jan 5, 2018
    BEST ANSWER: I can confirm the unit can extract Dolby Digital 5.1 (AC-3) from and Apple TV 4K unit via HDMI. I believe the Apple unit can output both AC-3 as well as E-AC-3 (7.1). I have no data on E-AC-3.
    Will this pass 7.1 from the Apple TV HDMI to my SPDIF-only receiver (which takes 7.1 of course)?
    A shopper on Dec 10, 2017
    BEST ANSWER: I haven't found any content on my Apple TV with 7.1, but it supports TrueHD which is usually 7.1. So I'm going to say yes.
    Has anyone tried this with Amazon Fire TV or Chromecast and had audio from the L/R output? Thanks.

    Work with Apple TV 4K
    I have an old audio receiver which doesn't have HDMI inputs. I used the Blackbird 4K Audio Extractor 18Gbps, HDCP 2.2 to extract the audio signal via optical to my older 5.1 Dolby Digital receiver, and I got the Dolby Digital working properly. My TV is a top end Panasonic 4K TV with supports HDR and has a full array local dimming (FALD) back-light. I tested it with my Panasonic 4K Blu-ray player and my new Apple TV 4K and it passes through the audio and video with Dolby Digital and 4K with HDR. In short it worked for me with 24fps and 60fps sources with 4K and HDR. Apple TV 4K and 4K Blu-ray worked great with it!

    This worked perfectly!!
    This solved my problem perfectly. I bought a new Apple 4K TV and was bummed that they took away the audio optical output. I have a great older Denon receiver that is not 4K compliant so I need to be able to go directly from the Apple 4K to the my Sony 4k TV to achieve 4:2:2 color space. Being able to extract out the audio from the HDMI output of the Apple 4K TV saved the day!! LOVE IT!!!!

    Doesn't work great for the Nintendo Switch
    My primary reason for buying this was to get an optical audio out from my Nintendo Switch to my Astro A50 headset. That works in a very limited fashion. The Switch outputs its audio in LPCM 5.1 which is an uncompressed multichannel format. Apparently, that bandwidth is too great to support all the channels over an optical audio cable, so I only get left and right audio channels to my headset. Center channel and rear channels don't make it through, so using the headset means I miss out on some of the audio. Since this only provides passthrough audio, there's no conversion of LPCM to Dolby Digital or DTS (which are compressed formats that are supported by the bandwidth constraints of an optical audio cable). The fact that this device doesn't work for my case isn't its fault, but it would help if there was a chart on the description page that listed which audio formats could be successfully extracted. If you can't change your surround source audio to Dolby Digital 5.1 or DTS 5.1, then this device won't work for you.

    I have the HDMI out going from the Blackbird to my audio receiver, so the video and audio that comes out of this device over HDMI looks and sounds exactly the same as if I weren't using it, so it didn't break anything in my A/V setup.

    The HDMI In port on the device is mislabeled as "HDMI Out", so it appears as if there are two "HDMI Out" ports. The diagram in the instruction manual is correct, however, so use that to figure out which HDMI port is the input.

    Plays well with others!
    I had an install with about 20' of HDMI cable to an AV cabinet and another 30' to the projector. I needed to tap the HDMI audio and send it to an audio amplifier for the venue's speakers.

    I bought a this audio extractor to replace a different brand extractor that wouldn't work with the HDMI booster/amplifier that was in the AV cabinet. This Monoprice audio extractor worked perfectly with my existing HDMI booster/amplifier right out of the box.

    I also bought the Monoprice VGA to HDMI adapter for legacy laptops and all three boxes in my HDMI signal chain work fine.

    Love the fact that Monoprice actually has people to talk to if you have technical or application questions.
