What it is and who it serves
The Plantronics DA75 USB-A/C digital adapter connects any Poly Quick Disconnect headset to a PC through a dual-connector cable. It targets call-centre staff who work from home or migrate to cloud platforms such as Avaya, Genesys and Cisco.
Installation ease and common pitfalls
Plug the USB-A or USB-C end into the computer and attach the headset QD plug; no driver download or software configuration is required. The adapter has no inline controls, indicators or audio tones, so volume and mute must be handled in the operating system or the softphone application.
Limits of the USB-A/C interface
The 1300 mm cable fixes the maximum working distance from the host device. Audio processing and acoustic protection rely on the host USB audio stack, so performance varies with the PC sound subsystem and the chosen communications platform.

Questions about this item
How can I confirm the DA75 USB-A/C adapter is functioning correctly after plugging it into my computer?
The adapter has no indicator lights or tones; verify it is recognised in your operating system sound settings and that audio passes through a connected Poly Quick Disconnect headset during a test call.
What is included with the 218266-01 DA75 and what must be purchased separately?
The box contains the DA75 digital adapter with a 1300 mm cable ending in both USB-A and USB-C connectors; a compatible Poly Quick Disconnect headset is required and sold separately.
Which DA series model should I choose if I need call control buttons and a Teams button on the adapter itself?
Choose the DA85-M instead; the DA75 has no controls, no indicators and no tones, while the DA85-M places call control and a Teams button on the adapter with red, blue and purple status LEDs.
