DM15

Next Generation acoustic protection with exceptional
sound quality.

Plantronics VistaPlus™ DM15 digital amplifier
offers breakthrough performance, enhancing
the capabilities of the most popular & trusted
amplifier in the industry – the Vista M12. 

Using Digital Signal Processing (DSP), the
DM15 offers unsurpassed acoustic protection
and provides a solution to contact centres 
needing to ensure compliance with new EU
noise at work legislation. 

SoundGuard DIGITAL provides two distinct
types of protection. Firstly, it monitors and 
predicts daily personal noise exposure, and
adaptively limits the maximum volume to
ensure the action levels specified by current

EU legislation are not 

exceeded.

Constantly on guard, it also identifies and 
eliminates sudden loud sounds. Network 
interference, a fax machine tone, or even 
a whistle blown by a malicious caller are 
all instantly reduced to a level similar to 
background noise. 

A particular strength of SoundGuard DIGITAL
is its ability to provide such protection whilst
not affecting normal speech – delivering 
face-to-face clarity of communication within 
a contact centre or office environment.

The VistaPlus DM15 also includes Plantronics
Call Clarity DIGITAL system, to deliver the 
clearest sounding calls. With the Automatic
Volume leveler, conversations can be 
maintained at a comfortable and consistent
level, regardless of the loudness of the 
incoming call.

Additionally, frequency response shaping
maximizes speech intelligibility, whilst phone
line noise is also reduced.
