The portable HA3D from Superlux is a robust headphone amplifier which provides three high-performance stereo headphone feeds with individual controls, from line-level sources. It produces high headphone levels with low noise and distortion, ideal for audio professionals and musicians who need to monitor in loud environments, for applications such as radio, TV, film or music production.
The HA3D accepts two balanced XLR line-level inputs or unbalanced 1/4" and 1/8" inputs. If additional headphone outputs are needed, you can connect multiple units using the 1/4" Loop output.
The unit features a sturdy aluminum-alloy housing to withstand the rigors of field or recording studio. It can be powered by two AA alkaline batteries or with an external DC adapter (available separately).
