Excerpt: I've generally had good experiences with the MPatch line of products, from their MPatch V1 to the Nano Passive Volume Attenuator. The MPatch V2 contains a few differences from the original version, the most important being a user removable attenuator.
Pros: Clean Sound, Includes A Pot Switched, Optional Headphone Amp, Variable And Switched, Well built
Cons: Headphone Amp Quality, Switched Only 12 Interval
Excerpt: This unit works wonderfully and is perfect for a small studio or professional studio. I use this box in two of my recording rooms and never have any issues. Most controllers, when you turn up the volume, change the way your audio actually sounds but this box keeps the audio as true as possible.
Excerpt: Pros: - If you have multiple sources or outputs, this is a great passive attenuation/switch.- Does not color the sound.- Knobs for volume are great. Cons: - Headphone amp isn't great. Buzzes occasionally.- Headphone volume is not independent.
