The Lencore Spectra ® Sound Masking LD6 demonstration unit consists of an individual self-contained noise generator, audio amplifier, loud speaker, power supply unit in a damped metal enclosure, powered by an internal transformer. The Demo model is used as a demonstration tool when presenting the system to prospective clients. The desktop unit, powered by a standard plug-in outlet, allows the presenter to make incremental adjustments to the volume. Using a small screwdriver, adjustments can be made to the spectrum of sound. The demo unit has an on/off switch on the unit. Each demo operates as a main unit and is solid state and consists of a CMOS/MSI digital random sequence noise generator, electronic amplifier and filter for active spectrum shaping, and is equipped with a 10-step volume control plus an additional continuous volume control. Range of sound level: 56-86 dBA. Additionally contained is a continuous and completely separate volume control for paging/music. The masking system can be uniquely adjusted to suit a variety of standard and non-standard ceiling 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). The Spectrum Graph above (measured in A-scale) depicts the range of spectra attained with standard fiberglass or mineral ceiling tile. The lower spectra provide the most unobtrusive sound, while the upper spectra provide the maximum speech privacy. Lencore's Spectra system can incorporate a high-quality paging and music system to handle all call paging, zoned paging, voice over IP, paging through the phone system, security
