garyh, the CD played through the stereo input is another strange thing. I have gained turned all the way down on that channel, and it still will not stop sound from coming through. I suppose that’s coming from the CD player.

I’ll keep you all updated with what happens

I didn’t do any adjustment on the amps for stage monitors or LR when I installed the board. I adjusted the pre-amp gain on the channels so that it was close to the volume needed with the fader at 0 like you said.
Sounds like I may need to turn down the amps some and the channel gain up.

To answer Mike C, nothing at all changed from the analog board switch out. The old board went bad, and I bought the other, and plugged it up same way.

I did have a chance to do a little testing last night after service. Had things going on and been busy…
During a song with the KB and vocals, I checked the PAFL on the KB and level was around -6. I check the PAFL on the LR mix and the 7-8 mix, and it was showing around -16 on the meter. Same for both mixes. Levels in house are good.
After service, I tried the signal generator at 0db on mix 7-8, and the level from my video mixer was high.

So, maybe I need more pre-amp gain on all channels, and turn down the LR amps? Forgive my ignorance please.

Thank you for the isolators.

I did not have any buzz on the old analog board It was RCA out, and my video mixer is RCA in.

As far as the level goes, since alt out is balanced, and I’m plugging in a mono adapter, would that be cutting the volume since it’s basically cutting out a conductor? The old board would have been an unbalanced out I assume.

Mike C, I just saw your earlier reply and tried to edit my post, but I don’t think it took.
What I have right now for the adapters is: https://www.sweetwater.com/store/detail/GPR101–hosa-gpr-101-rca-female-to-1-4-inch-ts-male-adapters-2-pack These are plugged into the two alt out jacks, and an RCA cable goes to the video mixer, with a splitter to a CD recorder. All the same as the other board except those two parts from sweetwater.
And yes, I have mix 7-8 post fade, post eq. All faders, including master are at 0, with the exception of a few adjustment to certain channels.

I’m not sure what you mean by a transformer. Would something like this be better? https://www.amazon.com/RCA-XLR-Audio-Cord-Professional/dp/B000V1RLI2 Sorry, I’m no professional sound man 😉

[idealtrucksParticipant]

Thank you for that information. So according to the block diagram, there is no gain on the mix
I will try those tests and post back my results.

Volunteer, I’ll check on the gain for the mix. I didn’t know that the mix as a whole had a gain.

For my connection, I have adapters to take the TRS jacks to RCA, and going to my video mixer. The video mixer then goes to the computer through and HDMI capture card. It’s the exact same connection that I had before, except the analog board had RCA connections so I had to add the adapters. There’s also a low buzz in the signal I’m getting at the computer now. Not sure if it’s the adapters though.

Mix 7-8 is not peaking very high, but I’ll check Wednesday service and get an exact level. It’s set to a post fade mix, with no process on the mix as a whole. The speaking mics do have compression turned on, but the sound out of the FOH speakers is great. The old board had compression on those channels as well. The music does not have any processing other other than EQ.
