Our take on the Behringer MA400 Ultra-Compact Monitor Headphone Amplifier

The Behringer MICROMON MA400 is a tiny personal monitor mixer that lets a performer blend their own mic with the monitor feed from the main mixer. It has an XLR mic input with a thru jack that passes +48 V phantom power, so condenser mics work, plus a stereo monitor input with its own level control and a mono/stereo switch. The headphone jacks take both 1/4-inch and 1/8-inch plugs, which suits hardwired in-ear monitoring. It is a simple analog box with no EQ or limiter, so it competes on price and size rather than features against bigger personal monitor mixers. Owners rate it highly for doing one job reliably.

Best forSingers and drummers who want more of their own voice or kit in their earsKeyboardists and guitarists using wired in-ear monitorsSmall stages and rehearsal rooms with a shared monitor feedAnyone adding a personal headphone mix without a digital mixer

  • Accepts both 1/4-inch and 1/8-inch headphones and earbuds

  • Very small and light, easy to clip to a mic stand or belt
Cons
  • No EQ, limiter or separate level for each source
  • Needs its own 12 V DC power supply, not bus powered
  • Mono/stereo switch is a simple toggle, not a full mixer
  • Plastic housing feels less rugged than metal stage gear

What reviewers say

  • 4.7 / 520 ratings

Owners rate the MA400 highly and describe it as a cheap, reliable way to get a personal monitor mix. Most praise the mic thru and phantom power passthrough and the dual headphone jacks. A few note the plastic build and the need for the included power supply.

What people mention
  • BuildMixedOwners say the plastic case is light and handy but less rugged than metal gear.
  • NoisePraisedThe ground lift switch is credited with removing hum on stage.
  • Phantom powerPraisedCondenser mics work because the mic thru passes +48 V from the mixer.
  • Headphone jacksPraisedBoth 1/4-inch and 1/8-inch plugs fit, which suits wired in-ear monitors.
  • PowerCriticisedIt only runs from its own 12 V DC adapter, so there is no battery or bus power.

About the Behringer MA400 Ultra-Compact Monitor Headphone Amplifier

The Behringer MICROMON MA400 is an ultra-compact personal monitor mixer and headphone amplifier for studio and stage. It lets a performer mix a microphone with the monitor feed from the main mixer and hear both through headphones.

The Mic In and Mic Thru XLR connectors let you plug a mic into the MA400 and send a line from Mic Thru on to the main mixer. It passes +48 V phantom power if the mixer provides it, so studio-grade condenser mics can be used. The Phones jacks accept both 1/4" and 1/8" headphone and earbud connections, which suits hardwired in-ear monitor setups such as singing drummers and keyboardists.

The MA400 works in stereo or mono and controls two independent sources. A Monitor Level control sets the monitor feed, and a Mono/Stereo switch and a Ground Lift switch are included. An LED shows when it is powered. It was designed and engineered in Germany.

Questions and answers

Does the MA400 pass phantom power to a condenser mic?
Yes. The XLR mic thru jack passes +48 V from your mixer, so a condenser mic connected to the mic input keeps working.
Can I use in-ear monitors with it?
Yes. The phones jacks accept both 1/4-inch and 1/8-inch plugs, so wired IEMs and earbuds connect directly.
Can I hear my mic and the monitor mix at the same time?
Yes. It mixes the mic input with the stereo monitor input, and the monitor level control sets the balance of the monitor feed.
Does it run on batteries?
No. It runs from the included 12 V DC power supply, and an LED shows when it is powered.
What is the ground lift switch for?
It breaks a ground loop that can cause hum when the MA400 is connected to a mixer and a stage feed.
Is it a full personal mixer with EQ?
No. It is a compact two-source monitor mixer with level and mono/stereo control, without EQ or a limiter.
