Busy call centers and help desks need one reliable headset that works with both legacy desk phones and modern PC softphones—without juggling cables or sacrificing audio quality. The HP Poly MDA524 QD USB-A Audio Processor (8L544AA) makes it simple. Plug in your Quick Disconnect (QD) headset, connect to your desk phone and USB-A computer, and enjoy seamless call switching, crystal-clear sound, and independent controls that keep agents focused and customers happy. Compact, easy to set up, and packed with smart audio features, it’s the upgrade your hybrid telephony environment has been waiting for.
Key Features
- One headset for both worlds — Seamlessly switch and merge calls between your traditional desk phone and PC/softphone using a single Quick Disconnect (QD) headset—no more swapping gear mid-shift.
- Crystal-clear conversations every time — Advanced noise and echo cancellation (Noise@Work technology, Anti-Startle protection, G616 compliance) keeps background noise out and voices natural so customers hear you clearly and you stay focused.
- Independent controls at your fingertips — Separate volume wheels and mute button for each audio channel (desk phone vs. PC) let agents fine-tune listening and speaking levels instantly.
- Smart LED status indicators — Quick visual feedback shows incoming calls, active calls, hold, and mute states so agents always know what’s happening.
- Advanced audio mixing (with Poly Lens app) — Play custom greetings on answer, record private voice notes during calls, or play PC audio privately without the desk-phone caller hearing it—all configurable from your desktop.
- Built for real call center life — Supports make/take/end calls, hold, merge, and walk-away freedom with standard 4-pin QD headsets. Optional EHS cable or HL10 lifter (sold separately) adds automatic headset answering for even faster response times.
