LD Systems HPA 2

The LD Systems HPA 2 2-Channel headphone amplifier is designed to make monitoring flexible and easy.

The two line inputs have independent gain control. Connect using standard 1/4" (6.35mm) jack or terminal block connections.

The HPA 2 comes with two headphone outputs and two line outputs using 1/4" (6.35mm) TRS jacks and two 3.5mm headphone outputs connected in parallel to these. Daisy chain multiple units together for group listening environments. Input signal and clip lights help you keep everything in check.

Configuration switches enable two people to listen to the same stereo signal with independent volume control, or listen to independent mono signals per headphone channel, acting as two independent headphone amplifiers. Further options let you configure the volume knobs for individual headphone volume control or configure one knob for global headphone volume control and the other as a separate monitor output level control.

The HPA 2 is compatible with high impedance headphones and very low impedances down to16ohms. Its capacitor-free output stage ensures the frequency response is not affected regardless of the headphones’ impedance.

Part of the LD Systems TICA®series, this ultra-compact headphone amp can be discreetly located with the supplied mounting plates or fitted into a 19 inch rack with up to three further TICA Series products using the optional rack tray for a bespoke system in minimal rack space.

The HPA2 is a great monitoring solution for audio professionals.
