- External 100-240V power supply
Part of the TICA®series, the HPA 02 is a two-channel headphone amplifier 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.
The configuration switches let two people 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 works with high impedance headphones and very low impedances down to16ohms. Its capacitor-free output stage means that the frequency response is not affected no matter what type of headphones you use - low or high impedance.
Its tiny (106 x 44 x 225) form factor and included mounting plates allow it to be installed discreetly. Alternatively, it fits into ¼ 19 inch rack. Use the optional rack tray to slot up to four TICA® series products alongside each other and build a system to your exact requirements, using minimal rack space.
A great monitoring solution for audio professionals.
