Tech Specs

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. Both LM6/ LM4 units are capable of driving two secondary models (LS6/ LS4) while the LM6-CVC/ LM6-RCVC units can power one secondary model.

LS6 and LS4 plenum secondary models duplicate the output of models LM6 and LM4. 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 RCVC has the option of an on/off switch (LOF). Performance characteristics of the LM6-RCVC remain identical to that of a standard main unit model LM6. 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.
