I think I am posting this in the correct location. Please correct me if I am wrong. So, I purchased the AKG MINI wireless system and honestly, it works great. Well worth the price; however, the rack mount adapters for these units are impossible to find and if you do find them, they are on backorder until November... So I make some rack ears for it. The custom rack mount I made provides ventilation for the top fan on the Gk 700RB by using a perforated 1U blank panel and the other rack ear is a solid 1U panel. Let me know what you think and feel free to ask any questions regarding the rack ears or the wireless system.
