This is the Avalon Design M5, the flagship 1-channel microphone preamplifier. I purchased it used seven years ago and have carefully used it at home, rack-mounted. I am selling it now to replace my equipment. I have used it until recently for vocal recordings, including commercial projects, and there are no problems with power or sound. The rack mount kit RM-1, dedicated power supply B2t, original box, various instruction manuals, and a novelty T-shirt (unused by me) are all included. As it is now discontinued, I believe this is a valuable opportunity to purchase it in this condition. I will wrap the original box in bubble wrap for shipping. Please note that this is a used item and is sold as-is, with no returns. Included accessories: • M5 main unit • Dedicated power supply unit (Avalon Design B2t) and dedicated power cable • Power cable • Rack mount kit RM-1 • Unit feet and mounting screws • Original box • Instruction manual • Novelty T-shirt A-Design M5 V5 U5 AD2022 Vt-737 Rupert NEVE DESIGN RND API Solid State Logic SSL Mic pre High-end mic pre
