Good, solid amp. I like the simplicity of it. The rear ins/outs are pro-level. My only issue is that the fans are extra loud. If you're on stage, it's not an issue. But, in a home studio, you will notice the noise. Musical Background: All Musical Style: All
I have never heard any amp put out this much fan noise. Sounds like a vacuum cleaner. I may be sending it back.
This power amp is inexpensive and high quality. It’s not as loud as some say but you definitely hear it. I use it with two PA speakers and get loud so the fans aren’t a big issue. I use my Eris 5s during tracking and the Gemini and PA after it’s all said and done.
