The Lencore Spectra® Desktop Sound Masking Unit is the most sophisticated unit
of its kind for providing speech privacy in home offices, small waiting areas
and for locations where it is difficult to install sound masking in the ceiling
or plenum. It helps create speech privacy by generating a comfortable background
sound. The Desktop Sound Masking Unit consists of an individual self-contained
noise generator, audio amplifier, loud speaker, and power supply unit in a white
damped metal enclosure. It is powered by an internal transformer with a 120
VAC plug (Plug-in can be configured for international use). Adjustments can
be made by a small screwdriver (provided), to the contour and volume control.
The Desktop Sound Masking Unit can be uniquely adjusted to suit a variety of
room conditions by making adjustments to the amplitude and spectra shapes. This
adjustment can be made in increments of +/- ½ dB. In addition, the system has
the adjustment capability to provide the most unobtrusive sound while obtaining
the maximum speech privacy that meets ASTM E-1130 standards for speech privacy
and sound uniformity. The spectrum shape adjustment ranges from 1 dB at 125
Hz to 20 dB at 8,000 Hz (typical). Range of sound level: 41-86 dBA.
