The A10-16 cable amplifier provides an extra boost to the microphone volume if required.
A10 Direct Connect Cable: Easily connect any Plantronics H-series headset to a headset-ready phone via the headset port with A10. Recommended for use in an environment with a mix of M22 amplifiers and direct connect solutions.* Allows H tops to be used in amplified and direct connect systems – and reduces the risk that the wrong headset will be connected (Polaris on an M22 or H top on a U10P) which would result in degraded transmit.
