The black AtlasIED M1000 8" Dual-Cone Sound Masking Speaker Blackby AtlasIED M1000 8" Dual-Cone Sound Masking Speaker Blackis designed to deliver an adjustable spectrum of sound masking in open office plans. A masking generator (not included) feeds pink noise into an Atlas Sound commercial 70V amplifier (not included), which in turn feeds the M1000 masking speaker to produce a random low-level sound throughout the coverage area. The result is increased speech privacy and a reduced perceived level of noise.

To ensure ample low-frequency response, the M1000 masking speaker's 734 cubic inch enclosure houses an 8" dual-cone loudspeaker and a 70.7V transformer. An external selector switch provides a selection of wattage taps ranging from 0.25W to 4W, plus an "off" position , for precise level adjustments. The masking speaker is designed to be installed above suspended ceiling systems or open ceiling spaces and is approved for use in plenum ceilings. Its suspension system features two factory-installed collapsible galvanized hangers configured to allow upward, downward, or horizontal orientation. Typically the M1000 is installed with contractor-provided strong ceiling grid suspension wire.

Depending on the size of the area you wish to cover and the level of sound masking you require, various combinations of generators and amplifiers can be used with the M1000. For example, an Atlas ASP-MG24 4 channel masking generator can be connected to an Atlas PA1001G amplifier to power up to about eighty M1000 sound masking speakers tapped at 1W. To meet most local code requirements, the M1000 includes a termination cover containing both knockouts and a strain relief. This system will allow the use of rigid or flexible conduit, if required, and easily accommodates "through" connections on the removable plate.

Related Questions and Answers

Q: 1. Can his fit the Tascam dr-70d?

A: Dimensions for the Tascam DR-70D Field Recorder are 6.7 x 4.2 x 2.2" (169 x 106.5 x 55.2 mm) with the top adapter attached and the interior dimensions of the ORCA OR-272 Sound Bag for Zoom F4 and F8N are 8.66 x 8.27 x 2.16" (220 x 210 x 55 mm). It looks like the thickness of the case interior is going to be too tight and the recorder will also be sitting low inside of the case. If you remove the top adapter from the DR-70D, then it will fit better, but still be sitting low. A better option for a case would be the ORCA OR-28 Mini Audio Bag for ZOOM F8, Zaxcom Max, Tascam DR70 & Other Recorders (B&H # OROR28), the ORCA OR-27 Small Sound Bag (B&H # OR27), or the PortaBrace Custom Case for Tascam DR-70D Audio Recorder (B&H # POARDR70D), which are all designed to fit the DR-70D.

Q: 8. I'm considering getting the Kaiser 9x12 enlarging easel. Has anybody used this? Do the blades stay square? Is it better build quality than the 4-bladed 11x14 beseler (which is actually cheaper)?

A: The Beseler 4 bladed easel will stay square compared to the Kaiser. No easel stays perfectly straight unless there are slider locks on all sides but it will certainly keep straighter than the Kaiser. Ideally you would want to tape down the side that doesn't have a clamp, that way it will always stay in position.
