burowyako Posted July 29, 2017 Share Posted July 29, 2017 I purchased a C4-LU642D video matrix switch earlier this year. This particular matrix downmixes audio streams so they can be pushed to rooms with stereo configurations. I'm pretty familiar with Composer Pro (9.1), but I can't figure out how to map the audio from the video matrix so I can listen to a video source in a particular room. The configuration is as follows: Fire TV ---> Video Matrix Input 1 Video Matrix RCA Audio Output 1 ---> Audio Matrix Input 4 Audio Endpoint 1 ---> Audio Switch 1 Room Selection 14 Audio Volume 1 ---> Audio Switch 1 Room Selection 14 Video Volume 1 ---> Audio Switch 1 Room Selection 14 Video's Audio Endpoint 1 ---> Audio Switch 1 Room Selection 14 When I choose to watch the Fire TV as the video source, the video signal comes through just fine but the speakers don't play the audio. Below are the snapshots of the current programming that is in place. Does anyone have an idea of what I'm doing wrong? I assume that Output 1 of the video matrix is associated with Input 1 because I can't find anything in Composer that would make me think differently. I even tried to map the stereo output of the Fire TV to an input on the audio matrix, but that didn't do anything, and I assume that shouldn't be needed since the video matrix audio is already mapped. Any help is appreciated! Video Matrix Connections:V Audio Matrix Connections: Room Connections: Link to comment Share on other sites More sharing options...
Matt Lowe Posted July 30, 2017 Share Posted July 30, 2017 you just need to make connections from the matrix to you audio switch like you would in the real world control4 will handle the rest Link to comment Share on other sites More sharing options...
Matt Lowe Posted July 30, 2017 Share Posted July 30, 2017 what are the audio switches that you have? i see that you have 2? Link to comment Share on other sites More sharing options...
Matt Lowe Posted July 30, 2017 Share Posted July 30, 2017 and if that is the case it would be best to send the audio to each of those separately. not from the same output that you have in the screen shot Link to comment Share on other sites More sharing options...

Unless I misunderstand something, the connection from the video matrix to the audio switch is already made. The output of the video matrix is mapped to Input 4 on both of the audio matrices. Is that the wrong mapping, or am I missing something? 2 hours ago, Matt Lowe said: what are the audio switches that you have? i see that you have 2? Both of the audio switches are the Control4 16-zone switches. 2 hours ago, Matt Lowe said: and if that is the case it would be best to send the audio to each of those separately. not from the same output that you have in the screen shot I currently have splitters so I can send the same audio signal to both switches. I read somewhere about the pros and cons of doing so, but I can't remember what the cons were. Even if the audio was faint, I would still hear something, right? If there is a way for the matrices to share a single input and have both of them know about it, I'd love to hear about it. My understanding is that the matrices run separately, so other than splitting the single sources that I have, I guess I don't know how else I can have sources available to both matrices.

burowyako Posted July 30, 2017 Author Share Posted July 30, 2017 @Matt Lowe, if you are referring to the physical connections from the video matrix to the audio switch, yes, those have been made. I just went through Composer again and verified that all connections have been set, and I assume that they are correct. Any other ideas? Has anyone programmed this specific video matrix before, or one like it? I'm scratching my head on this one. I feel like something is missing in Composer and I just don't see where.

burowyako Posted July 31, 2017 Author Share Posted July 31, 2017 As an update, Control4 Support looked at the issue. Since I had a single set of RCA ports on the video matrix mapped to different audio matrices, they said it was probably confusing the system. The technician told me that I needed to physically connect and map all eight sets of RCAs to the matrices before it would work, but that seemed like overkill. I only mapped the two sets of RCAs that I need to a single input on each matrix and it works like a champ. Thank you for your help! Link to comment Share on other sites More sharing options...
lippavisual Posted July 31, 2017 Share Posted July 31, 2017 That's what is called a double matrix issue. C4's logic can't deal with it. Link to comment Share on other sites More sharing options...
burowyako Posted July 31, 2017 Author Share Posted July 31, 2017 It was simple to fix, but it's interesting how it doesn't like it. I have a Sonos Connect used on the same system and I have it connected to both audio matrices using a "Y" cable. I haven't had any issues using the Sonos on both matrices, but it definitely didn't like it when trying it with the video matrix. Since I have some wiggle room with the video matrix, it isn't an issue. Out of curiosity, how should a device with a single output be handled when I have two audio matrices in the mix?

Matt Lowe Posted July 31, 2017 Share Posted July 31, 2017 its fine when a device has a single output totally different story when you are feeding a matrix from a matrix. Link to comment Share on other sites More sharing options...
burowyako Posted August 2, 2017 Author Share Posted August 2, 2017 Out of curiosity, what do you recommend to do with the two RCA outputs from the HC-800 when two audio matrices are involved? I currently have "Y" connectors coming out of both and into each audio matrix, but I only stream a single Pandora account for now. I'm able to listen to Pandora on all zones on all matrices without any issues, but I'm curious what happens when I add a second account. If I run one connection to each amp, then I'm basically limited to a single streaming service from the HC-800, correct? Link to comment Share on other sites More sharing options...
DerrickPanoutron123 Posted August 3, 2017 Share Posted August 3, 2017 I am also facing the same issue when I try to feed the audio from Video matrix to Audio Matrix. As per the control4 tech, two matrixes should not be connected. "Control4s switching logic doesn't support connecting one matrix output to the input of another matrix" Link to comment Share on other sites More sharing options...
