Incorporates 50 years of experience
Philips Speech Processing has designed professional
dictation systems for more than 50 years. Based on
this experience, as well as on customer requirements
Philips has now created a groundbreaking microphone
system that uses the effect of the acoustic pressure of
the surface.
Configurable to individual needs
In order to meet the future needs of your business, the
daisy chain feature of the boundary layer microphone
allows the connection of up to 6 microphones to the
recording device for larger tables.
360 degree pickup
The revolutionary boundary layer microphone is, as
opposed to other prevalent devices, non-directional. The
design allows sound pick-up from a 360 degree radius,
so that no important details are lost.
Easy setup and maintenance
The conference microphone is easy to set up and
put into operation. Unlike other systems, there is
no microphone stand required; just placed it on the
conference table. For maximum convenience, the cable
storage is integrated into the base of the microphone.
Everything you need
Philips accessories are designed to help you make the
most of your Philips dictation devices. They guarantee
optimal results and ensure that your Philips products
enjoy a long life.
