Plantronics A10-16 Direct Connect Cable

Easily connect a Plantronics H-series headset to most headset-ready phones via the headset port with the A10-16 cable amplifier.

Using an H-series headset with the A10-16 cable amplifier replaces the superceded Polaris solution.  However, the A10-16 cable will not allow the telephone to recognize that the headset is disconnected at the Quick Disconnect.  This allows some telephone systems to continue to route calls to the now disconnected headset

Plantronics recommends the M22 amplifier in most cases instead of the A10-16:

The Plantronics Vista M22 amplifier includes Clearline audio technology that provides numerous benefits, including:

• Automatic volume control
• Echo management
• Incoming noise reduction
• Outbound noise reduction
• Protection against loud incoming sounds
• Universal compatibility.
