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.
CALIBRATION : Unlike other
entertainment noise controllers
the GA904 has a chain of fixed
level settings making selecting a
specific noise setting easy. The
unit is pre-calibrated at the factory so accuracy is assured. A
standard Sound Level Meter
such as the GA601, may be
used to verify the settings or to
reset the calibration - a very
popular feature with the Environmental Health Officers.
