Sound Limiters from Lime Technologies - Noise Limiter / Noise Management / Noise Control Experts
We supply and install a full range of sound limiters, noise pollution control systems, noise limiting and noise warning devices to assist with noise management / noise control.
Sound limiter, also known as environmental noise control system, noise pollution control system or noise limiting device, is a prerequisite in many UK districts for the granting or renewal of an entertainment licence.
Most local authorities and environmental health officers require the installation of electronic noise limiters in village halls, pubs, bars, clubs, restaurants, health clubs, social clubs and other entertainment venues in order to minimise complaints regarding noise pollution. Additionally, with the advent of the smoking ban, it has become necessary for venues to fit some kind of noise warning sign to help control noise from customers talking loudly whilst smoking outside.
Lime Technologies are experts in noise control / noise management. We supply many types of noise limiters and our technical department will be pleased to offer you free advice on the appropriate type of noise limiter for your venue. If required we can also carry out installation. Please contact our sales department for a quotation on any noise control equipment.

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, resturant 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. This type of noise limiter 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 Mk2 Noise Limiter
Designed by sound limiter installers for straightforward installation and maximum functionality this noise limiter has been fitted in
many venues throughout the world. The NLX noise limiter offers all the features
you need and is local authority approved. The
NLX Mk2 sound limiter features fully automatic operation,
high intensity LED level indicator and 32 Amp switching contactor
with fire alarm / door switch interface. In our opinion this
is the best noise limiter
for most venues.
£429.00 GBP including VAT
Sentry Noise Limiter
The Formula Sound Sentry sound 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 the Formula Sound 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 Formula Sound 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 Formula Sound 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.

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
AVC2 Noise Limiter
The AVC2 Noise Limiter performs as an intelligent automatic 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 Formula Sound AVC2D is to fade between these steps and is almost undetectable in use. The more one tries to increase the volume, the more the Formula Sound 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 £556.00 GBP including VAT
The VCX Automatic Volume Limiter is a lower cost alternative to the Drawmer SP2120 and the Formua Sound AVC2. The Lime Technologies VCX is a superior product which uses a microphone to measure the actual sound level in the room for higher accuracy.
