Jabra Link 860 Audio Switch – Training & Recording Splitter for QD Headsets (860-09)

The Jabra Link 860 USB Amplifier (860-09) is an in-line USB audio processor that connects corded 2-wire or 4-wire headsets to a PC, delivering DSP-enhanced audio performance including acoustic shock protection and volume control. It's a professional-grade USB amplifier for environments where audio quality and hearing safety are priorities.

The Telecom Spot Take

Standard QD-to-USB adapters pass audio with minimal processing. The Link 860 goes further — it adds digital signal processing for cleaner audio, acoustic shock protection to guard against sudden loud sounds on calls, and precise volume control. This makes it the correct solution for contact centers handling calls from the public where call quality varies widely and operator hearing safety is a compliance concern. It also handles 2-wire and 4-wire headset connections that simpler adapters may not support.

Key Features

• DSP-enhanced USB audio — Digital signal processing delivers cleaner audio than passive QD-to-USB adapters.
• Acoustic shock protection — Guards against sudden loud sounds — important for operators on high-volume public call lines.
• 2-wire and 4-wire headset support — Broader compatibility than standard QD-only USB adapters.
• Precision volume control — In-line volume adjustment without touching the PC or softphone application.
• Professional call center grade — Designed for environments where audio quality and operator safety are priorities.
