CVC & RCVC

CVC

For use in traditional plenum space when central volume control is required. The Lencore Spectra® Classic Sound Masking LM6-CVC unit operates as a central volume control from which global volume adjustments can be made for up to 50 main units and covering up to 33,000 square feet system-wide. The unit consists of an individual self-contained noise generator, audio amplifier, loud speaker in a damped metal enclosure, powered by 16/18 volts AC and is capable of driving one secondary model.

Each central volume control unit is a main unit, solid state and consists of a CMOS/MSI digital random sequence noise generator, electronic amplifier and filter for active spectrum shaping. Each unit is equipped with a 10-step volume control and an additional continuous volume control, and the central volume adjustment control. Range of sound level: 41-86 dBA (measured at 1.5 feet from speaker). 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 1dB at 125 Hz to 20 dB at 8,000 Hz (typical).

RCVC

For use when remote wall access to the system adjustments is required. The Lencore Spectra® Classic sound masking LM6-RCVC unit operates as a central volume control from which global volume adjustments can be made remotely for up to 150 masking units and covering up to 33,000 square feet system-wide. The unit consists of an individual self-contained noise generator, audio amplifier, and loudspeaker in a damped aluminum enclosure, powered by 16/18 volts AC and is capable of driving one secondary model in addition to the aforementioned.

The remote central volume control unit, LM6-RCVC, allows adjustment to the volume of masking sound remotely. This model uses a remote rotating switch accompanied by a wall-mountable plate and is adjusted by rotating the dial from 0 to 10. Performance characteristics of the unit remain identical to that of a standard main unit model LM6.

Each remote central volume control unit is a main unit, 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, an additional continuous volume control, and the central volume remote adjustment control (as previously described above). Range of sound level: 41-86 dBA (measured at 1.5 feet from speaker).

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 spectrum 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).
