I am using an item I received from a professional studio. There are minor scratches from racking, but considering its age, it's in beautiful condition as shown in the photos. "GRACE design m201 ADC Factory" Domestic genuine product. 100V specification. Includes the main unit, power cable, and instruction manual (Japanese). Model equipped with a 100,000 yen worth of optional AD card. I heard it cost over 600,000 yen back then. The current GRACE design m201 has cut costs by eliminating unnecessary features and simplifying the construction, but this is a high-end model from the time when it was mainly used in professional studios, using high-quality parts and a heavy, solid body with excellent build quality. This type of pure audio class microphone preamplifier is quite expensive now due to the rising prices of parts, so I think it can still be useful for those looking for one. Also, since it is an optional AD card equipped model, it is recommended as a high-end machine that is easy to add to modern studios. A 2-channel microphone preamplifier that produces clear sound. It features a highly rigid chassis with a highly reproducible gain in 2dB steps, 48V phantom power, -20dBPAD, phase, ribbon mode, HI-Z input, and M/S decoder. Furthermore, it is equipped with an AD option, allowing for direct digital connection. The wide-range, high-resolution sound is a characteristic of GRACE. The current model is expensive, and this is an early model from an era when high-quality parts could be used extensively, so I hope to sell it to those who are looking for it or who wanted it. It's a rare microphone preamplifier that is hard to come by, and can be widely used for recording, as a guitar or bass preamplifier, or as a vocalist's preamplifier. No smoking, no pets.
