Adapter USB to QD POLY DA85 786C7AA HP POLY
The USB to QD POLY DA85 adapter enables connection of Poly headsets to computers and other devices with USB-A ports. Designed for compatibility with Poly (HP POLY) headset systems, the adapter converts the headset quick-disconnect (QD) plug to a standard USB interface, providing straightforward integration for office and remote-work setups.
The POLY DA85 adapter offers a compact and durable solution for converting QD headset connections to USB, preserving audio quality and microphone functionality. Its plug-and-play design requires no additional drivers, and it is made to match the mechanical and electrical compatibility of Poly headsets for reliable daily use.
Connect the headset's QD plug into the adapter's QD socket until it clicks, then insert the USB-A connector into an available USB port on your computer. The adapter is plug-and-play; once connected the system should recognize the headset for audio input and output. Use your operating system's audio settings to select the headset as the default device if needed.
For stable performance, connect the adapter directly to a USB port on the computer rather than through an unpowered USB hub. Keep the QD connector clean and free of debris and disconnect by pressing the release mechanism before pulling to avoid damage.
