UNIVERSAL AUDIO Apollo Twin MKⅡ Quad Transfer completed (Only the unit's license, plugins not included) Used a few times a month since new. About a year ago, due to a malfunction, the internal inspection and complete board replacement were performed by the official distributor, HOOK UP (labor cost about 30,000 yen). Therefore, I believe the internal components are practically new, so you can use it with confidence! After the repair, I switched to using another interface as my main one and only used this one when traveling, so I am now putting it up for sale. In preparation for the sale, I checked the headphone output, speaker output, connection to MacBook, and guitar input to Hi-Z. Operation is also problem-free. The accessories include the original box, instruction manual, and power cable, all as they were when purchased. If you wish, I will include a Thunderbolt cable and a USB-C adapter (for connecting to a MacBook, etc.), so please let me know in a message after purchase if you would like them included. For a smooth transaction, please create a UAD account before the item arrives. Thank you.
