The MPAMP4 compact headphones amplifier features a pass-through MIC/LINE input and a STEREO/MONO monitor input with individual level controls. It is very useful in recording studios or on stages when you need to mix and listen to two sound sources together.

This headphones amplifier is designed for use with all types of in-ear or over-ear headphones and therefore offers maximum flexibility for personal monitoring. It is typically used to combine your voice or instrument with other members of the band during a live concert or to listen to pre-recorded tracks during recording, allowing for customized mixing of the monitor signal. The THRU connection allows you to directly feed your voice or instrument to other live or recording equipment.
