## Summary description

The POLY MDA100 QD USB-A Analog Switch is designed for professional audio setups, featuring a QD connector and USB-A interface for enhanced flexibility and convenience. It allows seamless integration into various audio systems, ensuring reliable performance and ease of use.

## Long description

The HP POLY MDA100 QD USB-A Analog Switch provides a compact, reliable interface for professional audio and telephony setups. Designed to bridge QD connector headsets with USB-A equipped systems, this analog switch offers a straightforward way to connect legacy and modern devices without complex configuration. The unit supports quick-disconnect (QD) headset connections and a standard USB-A interface for easy integration with desk phones, softphones, and USB-enabled audio hubs.
Advantages
The analog switch delivers predictable audio routing and reduces the need for multiple adapters by providing a single, durable connection point between QD headsets and USB-A ports. Its mechanical QD coupling ensures a secure, repeatable connection, while the USB-A interface maintains broad compatibility with many host devices. The simple form factor minimizes cable clutter and supports reliable daily use in contact centers, offices, and home workspaces.
Suitable for
Connecting QD-compatible headsets to USB-A enabled desk phones or computers
Office and contact center telephony environments requiring quick headset changes
Home office setups using legacy QD headsets with modern USB-A ports
Audio systems where a durable mechanical QD connection is preferred
Key specifications
Connector types: Quick-Disconnect (QD) headset connector to USB-A interface
Signal type: Analog audio switching compatible with headset microphone and speaker lines
Compatibility: Designed for use with QD-equipped headsets and standard USB-A host ports
Form factor: Compact inline switch module for desk or cable integration
Durability: Mechanical coupling intended for frequent connect/disconnect cycles
How to use
To use the analog switch, connect your QD headset to the switch’s quick-disconnect port and insert the USB-A plug into the host device’s USB-A port. The switch operates without software drivers; once connected, the host device typically detects the audio interface and routes headset audio accordingly. For desk phones with USB-A audio support, follow the phone manufacturer’s instructions for selecting the USB audio path. When disconnecting, pull on the QD latch to release the headset cleanly from the switch.
Usage recommendations
For consistent audio performance, verify that your headset and host device support analog USB-A audio connections and ensure secure seating of the QD and USB-A connectors. Avoid applying excessive force to the connectors and keep contacts free from dust and debris. If using in a shared environment, inspect the QD coupling regularly for wear and replace when mechanical integrity declines.
