HP Poly RJ9 to RJ9 Cable with Rx Attenuator – 0.2M, For Desk Phone Headset Port (85R83AA)

The Poly RJ9 to RJ9 Cable with Rx Attenuator (85R83AA) connects two RJ9 handset ports with a built-in receive attenuator that reduces the incoming audio signal level. This is used in headset-to-phone configurations where the receive volume from the phone is too loud even at the phone's minimum volume setting — the attenuator reduces the signal before it reaches the headset, preventing audio discomfort or SoundGuard triggering on every call. At 0.2 meters, it is a very short in-line cable intended to sit directly at the phone's headset port.

Key Features

• Receive Attenuator: Reduces incoming audio signal level — solves the problem of phones that are too loud at minimum volume setting.
• RJ9 to RJ9: Standard handset port connectors on both ends.
• 0.2M Compact Length: Short in-line format designed to install directly at the phone port without adding cable clutter.
