Just wanted to follow up on the DL32R repair. it was a SMD Electrolytic cap C154 (47uf 25volt), Replaced the cap, problem repaired. Hope this helps the next person with the problem!

Thanks for your follow up!  This was the exact problem we had.  We also had 2 bad caps on the preamp board that we replaced because the top had split open, they were 220uf 25volt, 85 deg caps.  I'm adding some pics and notes to the thread for the next unlucky soul to experience this issue, I surely am thankful for your tracking down the issue, saved me alot of time. 

For the next person:
1. The 2 caps we replaced on the preamp board were soldered on both sides of the board so be very careful not to over heat it trying to get them out, I worked with someone heating and me working them back and forth to get them out, then clean old solder off.

2. If yours is fits the same chirping we had that ramped up on power up and then chirped at 11k then C154 is where I'd start for sure.  It is a surface mount capacitor so there is no need to remove the main board from the mixer.  When you remove the preamp board, you'll see the shield below it (pic attached).  You'll need to unplug all the connections that connect through the shield to the main board and then remove the screws from the bottom side of the mixer to release the shield.  Once the shield is off it's easy to get to C154.  You don't have to disconnect the ribbon cables from the preamp board if you don't want to, just pull them out of the way of the preamp board mounting screws and then you can carefully hang the board over the front of the mixer if you don't want to disconnect them.

Thanks again albundagus1, you were quite a blessing today!

The Soundcraft Ui24R I believe.

As the support and updates starts fading away from Mackie. I have a feeling that Mixing Station may be the only multi platform software that may extend the life of our consoles beyond future Apple firmware updates.

Hello, First-time user here. I have been using DL32r for a couple of years without issue. I just upgraded to Master Fader 5 and It worked perfectly for a few munites. Now although it states I am connected and I can see all my snapshots of saved shows, I am not receiving any signal to the iPad. Any suggestions?

The Behringer X32 and Midas M32 series consoles are fully controllable through the Mix Station App via iPhone and Ipad.

Followup. The Mixing Station App now has been updated to control several Mackie DL mixers.
