This headphone amplifier is aimed at recording studios, demanding home studio users, podcasters, and sound engineers who want a reliable monitoring system for multiple simultaneous headphones. Musicians appreciate the ability to achieve comfortable levels and tailored balance, while the operator benefits from quick level monitoring thanks to the LED VU meters.
