Overview

Ultra-compact 4-channel stereo headphone amplifier for all types of headphones.

The Behringer MicroAMP HA400 is an ultracompact four-channel headphone amplifier that provides flexible audio monitoring for studios and practice spaces. With the HA400, up to four people can listen to the same signal source, like a mixing board or audio interface, while controlling their own headphone volume level. Despite its small size, the HA400 delivers high-fidelity audio through four stereo headphone outputs, each with an independent volume control. It's powered by premium op-amps that minimize noise, even at loud listening levels.

Hear Every Detail With Premium Audio Performance

Each of the four stereo headphone outputs on the HA400 is driven by high-quality 4580 op-amps, providing ultralow noise and distortion for accurate audio monitoring. You'll hear every subtle nuance in your mixes and recordings. Even at high volume levels, the sound remains crystal clear.

Dial in Your Preferred Volume

The HA400 gives each listener independent volume control over their headphone feed. Just plug your headphones into one of the four stereo outputs, each with a dedicated volume knob. Now up to four musicians can monitor the same signal at their preferred loudness. It's perfect for letting a vocalist hear themselves over a live band mix.

Connect Your Gear With Versatile Audio I/O

On the rear panel, the HA400 offers a 1/4" stereo input to connect your mixing board, audio interface, instrument or other source device. It also has a 1/4" stereo output to send the amplified signal to powered monitors or an external amp. The HA400's DC power supply is also included for quick setup anywhere you have an electrical outlet. The HA400 provides flexible monitoring connectivity in a compact and affordable package.
