Optimizing your United Communications Deployment

As businesses increase their reliance on PC-based collaboration and communication tools, it's imperative that they remain committed to audio quality and performance. While VoIP services and other PC-based communication and collaborative tools offer compelling cost savings, call performance issues, such as VoIP latency and excessive noise, can undermine a company's image and overall efficiency. This is where the DA45 comes in.

This corded USB-to-headset adapter and audio processor is designed to help businesses optimize their unified communications solutions by providing several advanced technologies that bring clear, natural-sounding conversations to all softphone calls. And because the DA45 is compatible with all Plantronics H-series headsets, companies that are deploying unified communications solutions do not have to invest in new headsets to complete the transition.

Voice over IP PC

Advanced Audio Technologies for Business-Class Quality

To ensure clear, professional-sounding conversations, the DA45 audio processor offers wideband compatibility and utilizes a special echo suppression feature to combat the effects of VoIP latency. This combination helps to deliver crisp, clear sound on both ends. In addition to providing smooth, natural-sounding voice communications, these technologies combine to reduce listener fatigue, helping users remain comfortable and focused throughout the day.

Includes inline control

Inline controls are always easy to access.

Convenient, Versatile Design for Ease of Use

The audio processor's ergonomic design puts call controls, including volume, mute, and call answer/end, conveniently at the user's fingertips. And it includes PerSono Call software, which optimizes for unified communications by offering one-touch control over call answer/end features and letting users launch applications automatically with the processor's Smart Button features.

For added convenience, the trademark Quick Disconnect cord allows the headset to detach seamlessly without losing calls, making the DA45 especially expedient for professionals who need to move around or switch between Internet and landline calls. And with simple, plug-and-play USB connectivity, the DA45 ensures that getting started with calls is quick and easy, and that widespread implementation will not require downtime or technical support.

Two-year warranty

The DA45 USB Audio Processor is backed by a two-year warranty and includes PerSono Call Software.
