As a result, this happens without affecting anyone else on the unit. Additionally, mute and stereo/2-ch mode switches per channel let you quickly adjust how each channel behaves mid-session.
Built-Like-A-Tank construction means the HM400 holds up to the demands of touring, rehearsal spaces, and long-term studio use alike. Meanwhile, 7-segment LED metering on every channel and the main output gives engineers clear visual feedback on levels at all times. As a result, the HM400 suits any application needing reliable, flexible headphone monitoring across multiple users at once.
