Quick-Disconnect Interface with Integrated PTT for Legacy Portables

The Motorola BDN6676D is a mission-critical audio adapter designed to bridge legacy radio platforms with modern, professional-grade discrete accessories. Featuring a 3.5mm threaded jack, this adapter provides a secure, vibration-proof connection for earpieces and surveillance kits, such as the RLN5313 series. By attaching directly to the radio’s side external accessory connector, the Motorola BDN6676D ensures that high-stakes audio remains tethered to the operator even during intense physical movement or tactical maneuvers.

Equipped with a built-in Push-To-Talk (PTT) button, the adapter allows users to communicate without having to reach for the radio chassis, improving response times and operational efficiency. The integrated quick-disconnect latch facilitates rapid accessory changes in the field, while the CSA intrinsic safety rating makes it suitable for hazardous environments where equipment reliability is non-negotiable. Whether for undercover surveillance or standard patrol, the Motorola BDN6676D is the essential link for professional audio integration.

Frequently Asked Questions

Does this adapter work with standard 3.5mm headphones? While a standard 3.5mm jack may fit, this adapter is designed for threaded professional accessories. Non-threaded plugs may not maintain a stable connection or activate the microphone circuit properly.

Is this adapter compatible with APX radios? No. APX series radios use a different accessory connector. For APX models, the BDN6783B is the appropriate threaded 3.5mm adapter.

Do I need to program the radio to use the PTT on the adapter? No. The adapter is plug-and-play; the radio automatically detects the accessory and enables the PTT functionality on the adapter housing.
