Jabra GN1218 AC 2M Coiled Attenuation Cord

Jabra GN1218 AC 2M Coiled Attenuation Cord

The Jabra GN1218 AC 2M Coiled Attenuation Cord is a specialized connection cable designed to reduce signal strength (attenuation) between your Jabra headset and certain desk phones that require lower audio levels. This 2‑meter (approximately 6.5 feet) coiled cord features a modular plug on one end and a Quick Disconnect (QD) or RJ9 connector on the other, depending on your setup. If you experience distorted audio, echoing, or a “too loud” signal when using your headset with a specific phone model, this attenuation cord solves the problem. It is the perfect accessory for IT professionals and call centers dealing with incompatible phone and headset combinations.

How It Works

The GN1218 cord connects between your Jabra headset (or headset base) and your desk phone’s handset or headset port. The built‑in attenuation circuitry reduces the audio signal level by a fixed amount (typically 6–12 dB), preventing overload and distortion. This is especially useful when connecting a headset to older phone systems or models that output a higher‑than‑standard signal. The coiled design stretches from 1 foot to 2 meters, giving you flexibility to move while talking, then snaps back for a tidy desk. Simply plug the cord into your phone and headset – no configuration needed.

Compatibility & Design

The Jabra GN1218 AC is compatible with a wide range of desk phones that require signal attenuation, including many older models from Avaya, NEC, Panasonic, and Nortel. It works with most Jabra headsets that use a standard RJ9 or Quick Disconnect (QD) connection, including:

Jabra Engage series (with QD)

Jabra Pro series

Jabra Biz 2300/2400 series

Many corded Jabra headsets

The cord is coiled and extends to 2 meters (6.5 feet) when stretched. The modular plugs are gold‑plated for reliable signal transfer. The built‑in attenuation circuit is passive – no battery or external power required. The cord is black and durable, with reinforced strain relief at both ends to prevent breakage. It comes in a retail package or bulk packaging, depending on the supplier.

Why Choose This Product

Not all desk phones output the same audio level. Some older or specialized models produce a signal that is too hot for modern headsets, causing distortion, clipping, or discomfort for the user. The GN1218 AC attenuation cord solves this by lowering the signal to a standard level. Without it, you might need to turn down the headset volume to an unusable level or experience echo. This cord is a lifesaver for call centers with mixed phone models. It is also a great spare to keep in your toolkit for troubleshooting audio issues. The coiled design keeps your desk tidy while providing ample reach.
