Adapter Cable for 3.5mm Stereo to DB9 Connections

The Key Digital KD-3.5MDB96 is a 6-foot adapter cable designed to connect 3.5mm stereo outputs to devices with a male DB9 input. Whether you're integrating AV control systems, audio components, or serial communication gear, this cable simplifies the connection process with a plug-and-play solution. It's ideal for environments where high compatibility and stable signal transfer are essential, such as conference rooms, AV control hubs, and studio installations.

Supports Audio and Serial Signal Compatibility

This cable is commonly used in setups that require control signal transmission through a 3.5mm stereo connection to a DB9 serial input. It supports applications like RS-232 serial control used in home automation, commercial AV, and digital signage systems. By offering a direct 3.5mm to DB9 pathway, it eliminates the need for additional converters or complex adapters.

Ideal for Key Digital and Third-Party Control Systems

While the KD-3.5MDB96 is engineered to work seamlessly with Key Digital products, it also pairs well with third-party systems that utilize 3-conductor 3.5mm jacks and DB9 serial ports. This makes it a versatile addition to any integrator’s toolkit, offering flexibility across brands and control platforms without sacrificing performance.

Durable Construction for Long-Term Reliability

With high-quality molded connectors and a sturdy cable jacket, this adapter cable is built for frequent use in both residential and commercial installations.

It’s a reliable choice for permanent rack systems, desktop setups, and mobile AV solutions.

Plug-and-Play Setup with Clear Pin Assignment

The cable follows a 3-conductor TRS to DB9 pin assignment, ensuring consistent and accurate signal routing. This simplifies installation for techs and integrators by removing the guesswork often associated with custom pinouts or non-standard wiring. The male DB9 end is ready to connect directly into control systems, serial ports, or RS-232 inputs.

Ideal for AV Control, Digital Signage, and Automation

From controlling displays in boardrooms to syncing AV systems in lecture halls, this adapter cable supports a wide range of use cases. Its compatibility and quality construction make it a go-to solution for audio-visual technicians needing dependable interconnects for their system builds.
