New Federal Rules That Matter to You

January 15, 2010 the FCC has prohibited ALL wireless microphones, wireless in-ear-monitor (IEM) systems and wireless audio link systems in the 700 MHz UHF band. Users must absolutely cease operation on June 12, 2010. See the DSC Sound Tip page on wireless microphones.
Check your wireless microphone operating frequencies. You must be in compliance or risk nasty letters from the bandwidth auction winners (Verizon and ATT), legal action by the FCC, and lots of interference. If you are not sure how to check your systems and are in the Washington, DC, Virginia and Maryland region give us a call and we can help you stay legal.

February 15, 2010 the FCC has mandated the following warning be attached to all wireless microphone equipment, data sheets and ads.
CONSUMER ALERT
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones.

Contractors are now responsible for lead paint abatement.
April 22, 2010 the EPA has mandated that any contractor work that will involve painted surfaces in buildings built before 1978 and disturbing more than 6 square feet of surface must be trained in lead paint abatement or engage a licensed hazardous materials sub-contractor to remove paint and cut holes in affected surfaces. This will appreciably increase the cost of installing many sound systems for our clients. Most likely it will result in many designs resorting to surface mounted speakers and equipment that would have otherwise been recessed. If you have had to deal with asbestos on a project, you know the headaches of hiring abatement contractors, sealing off rooms and paying exhorbitant fees for disposal. While this may be a useless endeavor in 99% of cases built after the mid-60s, all will have to comply or face the risk of crippling federal litigation and enourmous fines. Violation of this rule may bring a fine of up to $32,000 per violation, per day. It would not take much to put most small sound contractors like us out of business. We will be asking ages and looking for cornerstones. While the present regulation relates to facilities occupied by children under 6 and pregnent women more than 2 days a week, the EPA is seeking to extend it to all occupied facilities.  http://www.epa.gov/lead/pubs/renovation.htm

An example: A typical 8" ceiling speaker requires a 9-10" hole in a plaster or drywall ceiling. That hole disturbs a little over 1/2 square foot of surface area.  Any specification for more than 10 to 11 speakers in a room built before 1978 will require an outside lead paint abatement subcontractor to cut the holes or strip the surface where cutting will be done A typical single electrical box for a microphone receptacle is about 8-1/2 square inches, 14 square inches for a double box. It would take 96 single boxes to reach the threshhold, but 9 single  boxes or 5 double boxes would equal 1 speaker cutout, further reducing the number of speakers before a subcontractor must be hired.
