This is a studio-cleared Grace Design m201 mkii. It's particularly noticeable for its beautiful sound. Rather than the natural, bass-heavy sound of something like a Millennia, it has tight bass and smooth, excellent highs, making it a superb microphone preamplifier. There are a few rack marks, but the top panel is scratch-free. Currently, I have several transparent/clean preamps at home, and due to compatibility issues, I haven't been using this one. However, I'm also considering the possibility of using it again, which is why the price is set as it is. Included accessories: Power cable The GRACE DESIGN m201 microphone preamplifier offers 2-channel input and XLR connectors for high-quality sound. - Brand: GRACE DESIGN - Model Name: m201 - Type: Microphone Preamplifier - Input/Output Terminals: XLR terminals (4) - Color: Black - Features: 2-channel input Thank you for looking.
