I received a spare unit that was used in a professional studio. I had been storing it with the intention of expanding my system someday, but I'm downsizing instead, so I'm putting it up for sale as it's a waste to keep. "Antelope Audio SATORI + R4S" Retail Price: ¥394,900 High-end monitoring controller & summing amplifier Domestic genuine product. Includes: Main unit, bundled R4S, USB cable, power cable, original box. This is a high-end monitoring controller made by ANTELOPE AUDIO. It features an analog summing function. It's rare to find these used, so I hope to sell it to someone who is looking for one or considering upgrading their quality. No smoking, no pets. Due to the dismantling and downsizing of my private studio, I'm unfortunately parting with my equipment. I will be listing various items, so please check them out.
