2-channel headphone amplifier

dual-channel headphone amplifier
Two line inputs with independent gain controls
Two line-level outputs
2 x mini jack (front) and 2 x jack (rear) for headphones
Signal and clip lights on each channel
External 100–240 V power supply

The HPA 2 is a two-channel headphone amplifier that makes monitoring flexible and easy.

The two line inputs have independent gain control. The connection is made via a standard 1/4" (6.35 mm) jack socket or a Euroblock terminal.

The HPA 2 features two headphone outputs – 2 x 1/4" on the front and 2 x 1/4" on the back – as well as two line outputs on 1/4" jacks. You can daisy-chain multiple units for group listening. Input signal and clip lights help you keep an eye on everything.

The configuration switches allow two people to listen to the same stereo signal or separate mono signals. Additional options allow you to configure the two volume controls for individual headphone volume or a control as a separate monitor output level.

Thanks to its compact size of 106 x 44 x 225 mm and the supplied mounting plates, it can be installed inconspicuously. Alternatively, it can also be placed in a 1/4 19-inch rack. With the optional rack tray, up to four products from the TICA® series can be placed next to each other, allowing you to create a system that exactly meets your requirements and takes up little space in the rack.

A great monitoring solution for all audio professionals.
