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-speaker volume control, hard wired zones and cannot be reconfigured via software as with a networked system.

 

Configuration

 

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

 

Modules

 

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 speakers, or approximately 6000 square feet.

 

 

 

 

 

 

The DS1092 features digital masking generator with adjustable low pass filter for tuning. The DS1092 incorporates a mixer to introduce paging and music signals into the system. A 40 watt amplifier provides power for up to 40 speakers, or approximately 10,000 square feet.

 

 

 

 

 

 

 

The DS3008 masking/paging processor features four independent digital masking generators, eight balanced line level inputs and outputs.
