Does this HDMI add-on module work with the NAD 7225PE?

[ Julius Apr 26, 2022 ]

1 answer

Unfortunately it is not compatible with the NAD 7225PE. It's compatible with NAD models C 390DD, C 368 , C 388, M12, M32, and C 658.

Does this work with the NAD C399 amplifier?

[ JOHN Apr 21, 2022 ]

1 answer

I do not know.. Your best bet is to go to the NAD site and check which card is for which component, they offer several.

[ RAUL Apr 22, 2022 ]

A review mentioned watching TV while listening to music. This is definitely something I would be interested in. Sometimes I may want to have a baseball game on while listening to music. How is that done with the MDC HDM-2?

[ Steve Apr 29, 2021 ]

Hi Steve -- it has been a bit since I've done this, but I believe I simply select my HDMI source (e.g., TiVO) first. I'll get the device on the channel I want to watch, and then I'll select a different source which isn't HDMI (e.g., optical). I'll double check later today or tomorrow, and will update my answer if I find my memory to be a bit rusty. ...but I'm recalling doing this for a football game last season.

[ Zachary May 03, 2021 ]

I connected the HDMI Out from the module to the HDMI-ARC In on my Samsung TV. The TV is both a source for my C388 and a display on its own (TV speakers are turned off), so if I want to listen to music, I just select the source I want and the TV continues to display while the NAD plays sound from the new source. The TV sound is sent to the integrated amp, but the display is not turned off if I select another source on the NAD. I do this daily, streaming Amazon Music HD while something else displays. It's a satisfactory configuration for my needs.

[ GERALD Apr 30, 2021 ]

If you switch to a video input, then back to an audio only input, the MDC will continue to pass the video to your TV while playing audio from the audio only input.

[ DAVID Apr 30, 2021 ]

The NAD MDC HDM-2 uses a pass through design allowing video signals to pass through while you switch to different audio inputs. Works very well.

[ STEPHEN Apr 30, 2021 ]

Does it work with M33?

[ Andrew Feb 13, 2021 ]

1 answer

According to the NAD website it does work with the M33.

Will I get the benefits of SACD from my Sony Blu Ray player with this upgrade card? Or will I basically just be getting CD Quality out of the SACD output from the Blu Ray player

[ Mark Nov 30, 2020 ]

2 answers

In my experience, my Yamaha Blu Ray SACD player does not pass the SACD audio via HDMI out. Therefore I get only CD (not SACD) audio through the NAD HDM-2. I would check the manual / specs of your Sony SACD player to see if it passes SACD audio through HDMI out. Even if it does, I'm not sure whether or not the NAD HDM-2 is converting the audio to PCM regardless.

[ DAVID Nov 30, 2020 ]

It depends on the Sony Bluray player you are using. Some of the Sony Bluray players that support SACD will bitstream the Audio for SACD out through the HDMI. In this case, you would then get the SACD audio out and would be using the DAC in the NAD device. If you output via the analog outputs on the Bluray player you would be using the DAC in the bluray player.

[ Ryan Nov 30, 2020 ]

Does HDMI sound better than optical output to the NAD amplifier?

[ Shawn Jan 22, 2020 ]

2 answers

HDMI cables can transmit more audio formats including the ones used on Blu-ray discs than optical cables. My reason for adding the HDMI module to the NAD amplifier was to add HDMI switching and control options for my system similar to those available with AV receivers. Whether HDMI cables are better than optical cables for those audio formats that both are capable of is a question for better ears than mine.

[ LEE R. Jan 22, 2020 ]

Much.

[ JERRY D Jan 22, 2020 ]

I'm trying to connect my Roku Ultra and Blu Ray player to the MDC HDM-2 and can't seem to get it to work. I have a Samsung TV with a one connect box and the only thing connected to it is the arc in to the hdmi of on the MDC HDM-2. What am I doing wrong? Obviously, I need help. Thank you for your time

[ KRISTINA Sep 13, 2019 ] Staff

Can anyone tell me if the hdmi out is the port used to connect to hdmi arc on my one connect box? I have a Samsung TV with a one connect box that has an hdmi arc in port. Thank you for your time

[ Bill Aug 29, 2019 ]

HDMI OUT is the ARC channel. Works very well!

[ STEPHEN Aug 30, 2019 ]

Yes, the HDMI IN will support ARC, and CEC. Keep in mind that this device only supports Stereo decoding, and will not function with Surround encoding. This caused some frustration for me, as I was unable to force certain applications on my Android TV (such as Netflix) to output in Stereo mode. This resulted in *no* audio output at all from those applications.

[ GARETT Aug 29, 2019 ]

Can I use an HDMI splitter to connect this to universal disk player? Any recommended?

[ Gregory Jul 19, 2019 ]

1 answer

This HDMI circuit board i for use with specific NAD stereo receivers. This allows you to have HDMI switching capabilities in the NAD receivers that did not have it to begin with. You can connect a disc player to these HDMI ports when used in a compatible NAD receiver to transmit audio and video signals. If you want to discuss this further or want more specific information, one of our friendly advisors would love to help you out! https://www.crutchfield.com/support/ContactUs.aspx
