Noise Limiters from Lime Technologies - The Noise Limiter / Noise Control Specialists
Lime Technologies supply and install sound limiters, noise pollution control systems, noise limiting devices
and noise activated warning signs.
Sound limiters, also known as environmental noise control systems, noise pollution
control system or noise limiters, are now a prerequisite in many parts of the
UK for the granting or renewal of an entertainment licence.
Most local authorities and environmental health officers require the installation of an
electronic noise limiting device in village halls, pubs, bars, clubs, restaurants, health clubs,
social clubs and other entertainment venues in order to minimise complaints regarding noise pollution.
Lime Technologies (noiselimiters.co.uk) are specialists in the noise control field.
We supply and / or install all types of noise limiter and our technical department will be pleased to
offer you free advice on the appropriate type of noise limiter for your particular venue.
If required we can carry out the installation for you. Prices start from around £750 + VAT
for a fully installed NLX sound limiter / noise limiter system, please contact our sales department for a quotation on any noise control
equipment.
New - Soundsign Noise Activated Warning Sign.
SoundSign is a highly visible noise activated warning sign that has been designed for use in environments where there is a need to
clearly warn or indicate when a preset noise level is reached. Soundsign is ideal for use in Factories, Entertainment venues, Hospitals,
Schools and Libraries.

bypassing.
Lime Technologies supply two distinct types of noise limiters.
1. Sanction Noise Limiter (Electronic sound monitoring and mains power switching
unit)
This type of noise limiter monitors sound levels within the venue using a built
in or external microphone. If the preset sound pressure level, usually set by
the local environmental health officer, is exceeded for a certain period of time
(normally 10 seconds) the mains power is disconnected from the sound equipment
for around 10 seconds and then automatically restored. This type of sound
limiter can be used in almost any situation but is the only viable solution when
bands or mobile DJs bring their own equipment to your premises. If you own or
manage a pub, bar, village hall, social club or other establishment where live music is
played you can safeguard your licence and avoid the possibility of large fines
by ensuring that musicians plug their equipment into a power socket controlled
by a noise limiter device of this type. Sanction noise limiters will usually need to be
fitted by a professional installer as mains voltage connections are involved.
Lime Technologies supply and install several different models of noise limiters, some
are shown below.
Lime NLX Noise Limiter - BEST SELLING
SOUND LIMITER!
Designed by installers for straightforward installation and maximum
functionality this noise limiter has been fitted in thousands of venues
throughout the UK, The NLX noise limiter offers all the features of more
expensive noise limiters and is local authority approved. It features fully automatic
operation, remote level indicator and sound pickup microphone, built in 30 Amp
switching contactor and fire alarm interface. In our opinion these noise
limiters offer
the best value.

Sentry Noise Limiter
The Sentry noise limiter works in conjunction with a relay or contactor (available separately
£130.00 GBP including VAT) and usually controls mains power. But the Sentry is
not limited to this function; any function that can be controlled by a relay or
switch can be controlled by Sentry noise limiters.
The Sentry noise limiter has connectors provided to interface with a range of equipment, plus
internally selectable options to make the system as versatile as possible.
Although its main application is to control mains power outlets in entertainment
venues it is not restricted to this application. Basically any function that can
be controlled by a relay or switch can be controlled by the Sentry. These may
include disconnecting loudspeakers, switching passive attenuators to reduce
system volume or acting as the trigger into an active attenuator system. It is
microphone driven and has its own microphone built in to minimise tampering.
The Sentry noise limiter also incorporates the facility to operate at two different sound
level thresholds which may be selected manually, by a remote key switch or
similar, or automatically by a time switch (switches not supplied). This allows
a venue to operate at different levels at different periods of the day. e.g.
when near offices or shops. An integral timer is available as a cost option.
£567.75 GBP including VAT
Castle GA904 Electronic Orange Noise Limiter
The Castletech Electronic Orange Noise Controller 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 activates. 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.

2. Electronic sound level attenuation system
A unit which is connected between the mixer or sound source, a karaoke machine
or CD player for example, and the main power amplifier. The unit continually
monitors the sound level and reduces the volume if a preset limit is exceeded.
This type of noise control system is only suitable if the sound system or at
least the power amplifier is permanently installed in the venue. An example of
this type of unit is the AVVC Noise Limiter below.
SP2120 Noise Limiter
The SP-2120 front panel features an integral security lock to ensure that
adjustments to maximum volume levels are implemented by key holders only. In
‘unlocked’ mode two front panel pre-sets are exposed and available for
adjustment. The first calibrates the 16 segment Left/Right bargraphs to the
incoming audio and dictates the point at which ‘protection’ processing
commences. The second sets the absolute volume level to which the sound system
is allowed to perform. If the SP2120 noise limiter receives increased signal levels, the
transparent ‘protection’ circuitry is activated which maintains the specified
system volume level without degradation in sound quality.
Step 1: Insert key to ‘unlock’ front panel and adjust VU meter pre-set until the
peaks of the incoming audio illuminate the red endstop 0dB LEDs.
Step 2: Adjust max output level pre-set until sound system volume reaches the
maximum permitted SPL as specified by the installer, client or environmental
Health Officer and remove key.
Installed in only a few minutes this unit completely eliminates the possibility
of ‘unauthorised’ volume levels. No sound quality loss even during heavy
protection processing. Housed in a 1U 19 inch rack mounting case. Isolation
transformer output option.
SP2120 Sound Limiters £339.00 GBP including VAT
FORMULA SOUND AVC2 Noise Limiter
The AVC2 Noise Limiter performs as an intelligent volume control and in operation is very
simple. If the average operating level is kept below the internally set
threshold, the AVC2 has no effect. If the average programme level exceeds the
threshold the unit will reduce its output level. The level is reduced in
discreet steps indicated by the led. bar graph meter on the front panel of the
unit. The action of the AVC2 is to fade between these steps and is almost
undetectable in use. The more one tries to increase the volume, the more the
AVC2 will decrease it so that the system will barely change in perceived level.
If driven to maximum attenuation, the output level will be reduced by more than
the increase in input level. The mixer or pre amp will probably be clipping, but
the system will actually be at a lower than normal level. A clip indicator is
provided to show when the input stage of the noise limiter is being over driven.
Reducing the input level will gently release the attenuation provided by the
AVVC noise limiters.
AVC2 £547.70 GBP including VAT
The Castle GA902 Noise Warning Sign is activated only when
the noise exceeds a preset level allowing exposed workers to wear ear
defenders only when absolutely necessary.
The GA902 Noise Activated Warning Sign is a self-contained unit housing its
electronics in a tough case and is easily installed and set up. The front
panel noise warning text is available as standard in EC or USA forms, but
can be ordered in any language and a variety of colours. The front panel is
completely blank when idle but brilliantly lit when activated to give an
easily noticed noise warning. Outputs from the master unit can also trigger
other external devices such as machines or process cut-off actuators.
