The LD Systems HPA 1 is a versatile headphone amplifier with high output power for stage, studio and home recording and the perfect connection solution for wired in-ear monitoring. The compact device in a robust, ergonomically shaped plastic housing with soft-touch surface and practical belt holder is extremely well equipped. In addition to locking XLR connectors for the balanced input of the stereo signal L/R, the HPA 1 has a 3.5 mm stereo socket as an aux input, which can be used in parallel for click or playback tracks. For safe operation, it is protected against excessive input levels, a hollow pin socket with negative internal contact enables the connection of a mains adapter in fixed operation. A 3.5 mm stereo jack serves as headphone and earphone output. Level and balance can be adjusted with handy knobs, a button switches from the stereo signal to the mono sum. For distortion-free playback and as protection against feedback, a full-fledged limiter is integrated. The LD Systems HPA 1 has two-colour LEDs for function overview, which indicate the response of the limiter at level peaks and the battery level, among other things. The headphone amplifier is an extremely lightweight 165 grams and can be operated for up to 12 hours with a high-quality 9V block.
