THANK YOU FOR CHOOSING POLSEN.
The Polsen HMA-41 Stereo Headphone Amplier is a compact and lightweight headphone amplier
that is ideal for studio recording, band rehearsals, or any application where multiple headphone
connections are needed.
The ¼-inch TRS stereo input accepts any stereo line output. The four TRS stereo ¼" headphone
outputs each have their own volume control, and there is no loss of signal when all four headphones
are connected. Wide frequency response guarantees full-range stereo sound. Individual amplier
circuits on each channel offer maximized output levels with low distortion and assures clean sound
even at high volumes. The included mini-plug adapter enables the HMA-41 to use a handheld media
player or smartphone as a source.
Among the benefits you’ll enjoy:
• Compact and portable. Easy to use
• Four headphone jacks each with independent volume
controls
• Wide frequency response (20 Hz-20 kHz) for full-range
stereo sound
• High power for precise monitoring at high volume levels
