EASY TO INSTALL l SIMPLE TO OPERATE lANTI - TAMPER PROTECTION In danger of losing your licence through Noise Complaints ? Are you complying with the Health & Safety legislation - The solution is simple, effective and inexpensive. Let the music play ! - with The Castle Electronic Orange Noise Controller. Everybody likes to party, but it’s all too easy to let music levels get out of hand - and when the morning comes, complaints come rolling in and your licence is on the line. The Castle Electronic Orange Noise Controller will keep your premises free from the risk of complaints and closure. The unit is connected to the main power supply for the amplification equipment, the Electronic Orange flashes a warning when pre set sound levels are exceeded. If the operator doesn’t turn down the sound within a pre-set time, an automatic cut off kicks in. The music never has to stop, because a warning light flashes if the limit is exceeded, and only when this is ignored does the power supply cut off to prevent further abuse. Pioneered by Castle, this unit, approved by The Environmental Health, is used by thousands of venues through the World, and the latest model is as easy to use, robust and reliable as ever. GA904 AUTOMATIC CUT OFF : The cut off is similar to normal mains power removal, and will not damage the amplification equipment. After a pre-set time, power can be restored automatically or manually. A key operated ‘cabaret’ over-ride is also provided. FEATURES : 3 colour LED bar graph display showing Sound Pressure Level (SPL) ’Switchable ‘A’ weighting, or ‘B’ weighting for more effective Bass control. ’External trigger facility - e.g. contact on Fire Door ’Level, Microphone and external indicators show cause of cut off. INSTALLATION : The GA904 can be installed at low cost by any competent electrician. Detailed instructions are supplied.
