Plantronics DA90 USB Digital Audio Processor (201853-01)

$66.17 $104.00

Plantronics DA90 USB Adapter Benefits:

Take control of your VoIP calls with the Plantronics DA90 audio processor.  With VoIP quickly becoming the business choice for communication, using a headset and adapter have become a necessary endpoint device.

The DA90 adapter gives you easy to use inline volume controls, mute, and call answer ability with compatible software.  This allows you to raise/lower your caller’s volume quickly to a good level for you, ensuring every call is crisp and clear.  You can also easily mute your microphone with a push of a button, if you need to converse with a co-worker.

For reference, lower priced adapters exist, but will not include inline controls.  Without inline controls, you save money but will be slowed down by using your mouse to navigate software and computer settings to adjust volume controls and other features.

Another great feature of this adapter is the multiple LED indicators.  With regard to calls, the Call LED indicator will flicker for incoming calls, hold steady during a call, and flash when a call is being held.  Your Mute LED indicator will light red when you have muted your headset’s microphone, giving you the confidence to know the status of your microphone and what your caller can and cannot hear.

Choosing the right headset is critical for all-day comfort and productivity, but choosing an audio processor with the features you require is equally important, if not more.
