I am using this after receiving it from someone who used it in a professional studio. There are minor scratches from racking, but considering its age, it is in beautiful condition as shown in the photos. "GRACE design m201 ADC Factory" Domestic genuine product. 100V specification. Main unit, power cable. Model equipped with optional AD card worth approximately 100,000 yen. I heard it cost over 600,000 yen at the time. The current GRACE design m201 has simplified construction and removed unnecessary features to reduce cost, but the price has not been lowered. This is a model from the era when it was treated as a high-end device and mainly used in professional studios, featuring abundant high-quality parts and a wonderfully constructed, weighty body. Pure audio class microphone preamplifiers of this type are very expensive nowadays due to rising parts costs, so I believe it can still be useful for those who are looking for one. Furthermore, as it is a model equipped with an optional AD card, it is recommended as a high-end unit that can be easily integrated into modern studios. 2-channel mic preamplifier that produces a clear sound. Equipped with a highly rigid chassis, highly reproducible gain in 2dB steps, 48V phantom, -20dB PAD, phase, ribbon mode, HI-Z input, and M/S decoder. It also features an AD option, allowing for direct digital connection. GRACE's characteristic wide-range, high-resolution sound. The current model is expensive, and this is an early model from an era when abundant high-quality parts could be used. I would be happy to pass it on to those who are looking for it or have wanted it. This is a rare microphone preamplifier that is difficult to obtain, and it can be widely used for recording, as a preamplifier for guitar and bass, or as a preamplifier for vocalists.
