Classic Speaker, Ceiling Plate, brushed aluminum housing, White cover, Secondary

Lencore’s Classic Sound Masking unit consists of an individual self-contained noise generator, audio amplifier and loudspeaker in a damped metal enclosure, powered by 16/18 volts AC. The main (LM6) is capable of driving two secondary units (LS6) while the LM6-RCVC unit can power one secondary model.

Secondary units are connected to a main unit that is solid state and contains a CMOS/ MSI digital random sequence noise generator and filter for active spectrum shaping. All units are equipped with a 10-step volume control plus an additional continuous volume control.

The remote central volume control unit, LM6-RCVC, allows adjustments to the volume of masking sound remotely. This model uses a remote rotating switch accompanied by a wall-mountable plate and is adjust by rotating the dial from 0 to 10.

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.
