THANK YOU FOR CHOOSING POLSEN.
The Polsen HPA-4X2 Stereo Reference Headphone Amplier is a compact and powerful headphone
amplier that can withstand the rigors of professional use. It is ideal for studio recording, stage
monitoring, or any application where multiple headphone connections are needed.
The four ¼-inch TRS stereo headphone outputs each have their own volume control, and each channel
has an individual amplier circuit that offers maximized output levels with low and minimal distortion.
Wide frequency response guarantees full-range stereo sound, and there is no loss of signal when all
four headphones are connected. The ¼-inch TRS and stereo RCA inputs accommodate a wide variety
of input sources. The mini plug cable used with a mini plug adapter lets the HPA-4X2 use a handheld
media player or smartphone as an input source, and the mini plug adapters allow monitoring with
earbuds.
