70 Volt Sound Masking Systems

70 Volt sound masking systems have been a professional approach to commercial sound masking since the mid-1970s. Even with the development of networked sound masking systems, centralized systems are often still a good choice in some workplace environments. Centralized systems provide manual per-loudspeaker volume control, hard wired zones and cannot be reconfigured via software as with a networked system.

70 volt sound masking systems are well suited to environments having uniform acoustical conditions and basic paging requirements. Loudspeakers are “daisy-chained” together into hard wired zones using standard two conductor audio cable. All loudspeakers in a given zone receive the same audio signal. Loudspeaker mounted volume controls provide adjustment on a local basis.

 

Sound Masking Generators/Mixers/Amplifiers for 70 Volt Systems

 

The DS1042 features a digital masking generator with adjustable volume and low pass filter for tuning. A 25 watt amplifier provides power for up to 25 loudspeakers, or approximately 6000 square feet.
