I am using this bag with a MixPre 6 II and 4 wireless systems, a battery power bank, and some other accessories and it can fit them great. I use normal XLR cables for both the boom mic and for the wireless receivers and the size of the bag is just a bit tight for my setup, and by that I mean that there is a bit of pressure on the XLR cables in the bag but it works just fine. If you choose to use low profile XLRs (or maybe even right angle XLRs), this bag is PERFECT for a MixPre setup like this.
The honey comb frame of the bag is very durable and it seems that it can take some damage without any problems and due to its size, it can easily be put in a backpack for traveling.
Overall I am very satisfied with my purchase and would 100% recommend this bag!
