Product information "LD Systems HPA 1"
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 a soft-touch surface and practical belt clip is extremely well equipped.
In addition to locking XLR connectors for 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. It is protected against excessive input levels for safe operation, and a hollow pin socket with negative internal contact enables the connection of a mains adapter in fixed mode.
A 3.5 mm stereo socket serves as a headphone and earphone output. Level and balance can be adjusted using handy rotary controls, while a button switches from stereo signal to mono sum. A fully-fledged limiter is integrated for distortion-free playback and protection against feedback.
The LD Systems HPA 1 has two-colour LEDs to provide an overview of its functions, which indicate the response of the limiter at peak levels and the battery level, among other things. At 165 grams, the headphone amplifier is extremely lightweight and can be operated for up to 12 hours with a high-quality 9V block.
