Critic Reviews

Behringer Micromon MA400 Monitor Mixer - Mike Dolbear

mikedolbear.com

The Behringer MicroMON MA400 Monitor Headphone Amplifier is a budget-friendly gem for musicians seeking personal monitoring solutions. Priced under £20, it delivers a clear sound with two separate volume controls, allowing for a customizable mix of your instrument and the band. Its compact size and sturdy metal construction make it a practical addition to your rig, especially for smaller gigs where space is tight. However, it lacks battery operation and requires additional cables and mics for full functionality. While it excels in simplicity and affordability, those expecting extensive features may find it lacking. Overall, it’s a solid choice for musicians needing straightforward monitoring without breaking the bank.
