Product Information
Full details
The Behringer HA400 is an ultra-compact, flexible 4-channel stereo headphone amplifier designed for musicians and audio professionals needing to monitor audio simultaneously. Its key benefit is providing individual volume control for up to four listeners from a single stereo source, ensuring everyone hears the mix clearly without compromising audio quality. A potential caveat is its reliance on an external power adapter, requiring an available outlet. The HA400 features high-power stereo amplifiers for clear sound, ultra low-noise op-amps, and individual volume controls for each of the four outputs.

FAQs
Can I plug in 3.5mm headphones?
Yes, you can use headphones with a 3.5mm (1/8 inch) jack by using a standard 6.3mm (1/4 inch) to 3.5mm adapter. The HA400 outputs use 6.3mm jacks.
Does the HA400 require batteries?
No, the HA400 is powered by an external 12V DC power adapter, which is included with the unit.
How many headphones can I connect simultaneously?
You can connect up to four pairs of headphones simultaneously.
Can each person set their own volume?
Yes, each of the four headphone outputs has its own independent `LEVEL` control, allowing each listener to adjust their volume.
What kind of audio source can I connect to the input?
You can connect any stereo line-level audio source, such as the headphone output of an audio interface, a mixer's main output, or a portable music player with a stereo output.
Is the HA400 suitable for live performances?
Yes, its compact size and ability to provide individual monitoring levels make it suitable for small-scale live performances where multiple band members need to hear a monitor mix.
Does the HA400 affect the original stereo image?
No, the HA400 processes the stereo input signal and distributes it to the individual outputs while maintaining the original stereo integrity.
Troubleshooting
No sound from any output
Ensure the power adapter is securely connected to the unit and a working power outlet. Verify that the audio source is connected to the `STEREO IN` and is producing a signal. Check that the `LEVEL` controls are turned up.
Sound only in one earphone or channel
Check the headphone cable connection for that specific output. Try a different pair of headphones to rule out a headphone issue. Ensure the stereo input source is properly wired (left and right channels).
Distorted or noisy audio
Reduce the `LEVEL` control for the affected channel(s). Ensure the input signal from your source is not clipping or overloaded. Check that the power adapter is the correct one supplied with the unit.
Low volume from all outputs
Turn up the `LEVEL` controls on the HA400. Check the volume output of your source device. Ensure the headphones being used are not excessively high impedance without sufficient power from the source.
