Behringer Ultra-Compact Monitor Headphone Amplifier
Capable of stereo or mono operation, the MA400 is a powerful little mixer that allows you to control two independent sources, a microphone and the monitor feed from your main mixer. Simply adjust the Mon Level control to a comfortable setting and then dial in all the "me" you want with the Mic Level control.
The MA400 features XLR Thru jacks and provides superb noise-free operation. Just connect your mic to the Mic Input and send a line from the Mic Thru to your main mixer. You can even use studio-grade condenser mics, as the MA400 will pass +48 V phantom power, if your mixer is so equipped. The Phones jacks accept both 1/4" and 1/8" headphone and earbud connections, making the MA400 ideal for hardwired IEM (in-ear-monitor) applications, such as singing drummers and keyboardists. The MA400 comes with a 12 V DC power supply and an LED to indicate when it is powered up.
