Plantronics D251N Headset and VistaPlus DM15 Amplifier

The SupraPlus Digital Monaural NC Headset has been created to work with the VistaPlus adapter to optimise audio performance in Health and Safety conscious work environments. Meeting the lower sound exposure thresholds required by Noise at Work legislation often means that the headset receive is quieter than previously experienced. This can make calls harder to hear and potentially reduce productivity. SupraPlus Digital uses on board memory to store the exact parameters characterising each individual headset. VistaPlus reads these parameters and tunes its setting to optimally match with the headset and lifting the receive level to enhance ease of listening, whilst remaining within the limits set by the New (2003/10/EC) Noise Directive.

SupraPlus Digital can only be used with the DM12 VistaPlus adapter offering the highest standards in the market in terms of sound protection and sound clarity. No additional bottom cable purchase is required as it is supplied in the box with the headset.
