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.

Among the benefits you’ll enjoy:

• Durable and compact. Easy to use.

• High output level for precise monitoring at high volume

• Low noise circuitry

• ¼-inch TRS and RCA inputs

• Four headphone jacks each with independent volume

controls

• Wide frequency response (20 Hz-20 kHz) for full-range
