VistaPlus TM AP15 Audio Processor Enhanced Contact Center Productivity October 2008 Slide 2 2Plantronics, Inc. October 2008 VistaPlus TM AP15 New Improved Audio Processor for Contact Centers DSP-based with AudioIQ technology Key Features Multiband compression for improved intelligibility (new) Background noise compensation (new) Echo canceller (new) Incoming & outbound noise reduction Automatic call volume leveling Startle protection Available now in U.S. and Canada $150.00 MSRP Slide 3 3Plantronics, Inc. October 2008 Multiband compression for improved intelligibility (new) Corrects for signal loss anywhere in the bandwidth Background noise compensation (new) Automatically adjusts to compensate for varying levels of background noise throughout the day delivering clearer audio even in a noisy contact center Echo canceller (new) Outstanding echo cancellation ensures great audio even on VoIP systems Startle protection Reduce loud incoming noises (whistles, fax tones, etc.) Automatic call volume leveling All calls, no matter what the source, come in at the same user-controlled, comfortable level Incoming noise reduction Reduces line noise when talking Background noise reduction Reduces transmission of background noise when listening What is AudioIQ technology Slide 4 4Plantronics, Inc. October 2008 VistaPlus AP15 Multiband Compression Frequency bandwidth is split into sections 16 bands of 250Hz Analog audio processors treat the whole signal as a single band This DSP algorithm, part of AudioIQ, strives to deliver the optimum frequency response at all times Mobile & cordless phones and long line lengths contribute to loss in the bandwidth, i.e. poorer audio quality received by the agent This DSP algorithm reviews the incoming signal in its component parts & compensates each 250Hz band to deliver an overall signal that is corrected for loss anywhere in the bandwidth Not just the level at 1kHz (traditional level compensation) Replacement of lost frequencies clears up speech, making it crisper and clearer thus reducing errors and repeats Slide 5 5Plantronics, Inc. October 2008 Multiband Compression Preferred frequency response: high quality call Frequency (Hz) dB Slide 6 6Plantronics, Inc. October 2008 Multiband Compression Poor frequency response: poor quality call Lower overall level High frequency loss The overall signal volume (level) is reduced and the high frequencies have lost even more. Frequency loss can occur at any frequency. The loss here is shown at the high frequencies, which is most typical on sub-optimal calls. Frequency (Hz) dB Slide 7 7Plantronics, Inc. October 2008 Multiband Compression Poor frequency response: poor quality call Low volume compensation only Does not recover lost high frequency components Increase in total gain The loss in volume can be compensated for by analog audio processors but no correction is made for additional lost volume at other frequencies (in this case, the higher ones). Frequency (Hz) dB Slide 8 8Plantronics, Inc. October 2008 Multiband Compression Poor frequency response: poor quality call Full audio compensation High frequency compensation Increase in total gain Not only is the loss in level compensated for by the AP15 but also lost additional level at other frequencies is compensated for making speech richer, clearer and more easily understood. Frequency (Hz) dB Slide 9 9Plantronics, Inc. October 2008 VistaPlus AP15 Background Noise Compensation Agent selects their preferred listening volume This DSP algorithm, part of AudioIQ, uses background noise from the headset mic (there will be some even with a NC mic) and adjusts the receive level automatically to compensate for changing levels The level of background noise inside the contact center will most likely change during the day (e.g. different numbers of agents work at any given time) AP15 adjusts the receive level for the agent automatically There is no need for the agent to try to compensate by making adjustments at the volume control; the algorithm does this automatically Results in better receive sound especially in noisy contact centers so agents can hear better Slide 10 10Plantronics, Inc.
