    Aphex AX454 HeadPod 4 Headphone Amplifier

    If the headphone output on your existing gear just isn't loud and clear enough, or you need multiple headphone outputs with independent level controls, the HeadPod 4 delivers. But the HeadPod 4 gives you more than just volume. It's designed to deliver clean, clear, undistorted sound at any level - ideal for long periods of listening without fatigue. The input signal can be fed from separate balanced connections; a single extension from your existing headphone output; or digitally via S/PDIF. Since it places no load on your existing headphone output, your audio will actually sound better through the HeadPod 4. Four fully independent amplifiers ensure maximum efficiency with minimum crosstalk and distortion, even when all four outputs have completely different sets of headphones connected. Housed in a rugged, metal chassis, the HeadPod 4 is ready for any environment from the desktop to the rehearsal room, with its optional mic stand bracket. Whether you're a musician, audio engineer, broadcaster, or just over old, tired headphone outputs, the HeadPod 4 is for you.
