Anleitung Zusammenfassung
Compact assembly adds low-level sound into environment to obscure ambient noise, achieving conversational privacy in designated areas. Easy-to-install system may be used in general application to increase privacy and/or productivity in individual cubical and work areas by “blocking out” surrounding conversation. It is also used in individual office areas, common waiting areas, and professional offices where confidential conversations occur. The equalized masking sound lowers intelligibility and “masks” disruptive outside sounds. GENERAL DESCRIPTION The Masker AM1100 Series is an easy-to-install, high-performance masking system that includes a built-in power supply, digital pink-noise generator, 2-watt amplifier, 4" loudspeaker and selection of optional installation and performance enhancements. Compact assembly is housed within a 6" metal cube enclosure with one point suspension to allow 360° positioning in ceiling plenums. Easy-to-operate control panel features on/off power switch, screwdriver-adjust master SPL level control, knob adjust attenuator (11.2 dB per step), and two screwdriver-adjust low-pass filters. For installation convenience, the sound out-put curve of The Masker is pre-set at the factory to meet most masking applications (see Fig. 1). Custom curves to satisfy individual customer specifications are also available upon special request. The 117VAC versions are standard with transformer, IC electronic regulator, replaceable fuse and grounded plug or conduit connector for termination. The 16VAC version is equipped with IC electronic regulator, re-settable circuit breaker and 8" leads for connection to external power transformer. Models are finished in black epoxy and configured as listed in the chart below. Option abbreviations are as follows: (L) AC line cord with molded plug and (H) 4' suspension chain with “S” hook.
