FAQs:

The mixer has worked fine for me without any issues. I use it via the VGA monitor, the software is managed in the mixer itself, the pics of the monitor are with faders and what-not were taken when I posted the auction. I don't know if the apps to manage it via a tablet wirelessly are still available. They are likely available somewhere on-line but probably not in the Apple store, etc. since I don't believe this model is made anymore.

Here is a video from the manufacturer with the set-up info and view of the software. The software and functions shown in the video are the same that are useable via the mouse/VGA monitor set-up I used with this mixer: https://youtu.be/RxGgVvofY2k?si=6FunFZR3xauvfqmN

I can not ship to a PO Box, only to a physical address. USPS shipping rates far exceed the flat rate with this listing. 

Because of the size of the item, shipping without the monitor doesn't result in any shipping cost saving.

Let me know if you have any other questions. Thanks for looking!
