Sound Limiters By Lime
Technologies - The Sound Limiter Specialists
Sound limiters, also known as environmental noise
control systems, noise pollution control system or just plain 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 sound limiter in village halls, pubs, bars, clubs,
restaurants, health clubs and other entertainment venues to minimise complaints
regarding noise pollution.
Lime Technologies (noiselimiters.co.uk) are specialists in the noise
control field. We supply and / or install sound limiters and our technical
department will be pleased to offer you free advice on the appropriate type of
sound limiter for your particular venue. If required we can carry out the
installation for you. Prices start from around £550 + VAT for a fully installed
sound limiter system, please
contact our sales department for a quotation on any noise control equipment.
Quantity discounts are available - please call or email for pricing if
purchasing more than one unit.
PLEASE NOTE:
Legislation provides that as from 1 October 2006,
local authorities have been able to issue fixed penalty notices in the region of
£500 to the person in charge of the premises at the time of any noise complaint.
This could be the license holder, manager or any other employee.
This is in addition to their existing powers
to serve noise abatement notices and review premises licenses.

Lime Technologies supply two distinct types of
sound limiter.
1.
Sanction Sound Limiter (Electronic sound monitoring and mains power switching
unit)
This type of sound 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 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 device of this type. This type of sound 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 sound limiter, some are shown below.

Sentry Sound Limiter
The Sentry Sound Limiter works in conjunction with a relay or contactor
(available separately £115.00 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 Sentry.
The Sentry 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 sound 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.

Castle GA904 Electronic
Orange Sound 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 AVC below.
SPL2120 Sound Limiter
The SPL2120 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 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" rack mounting case.
Isolation transformer output option. |

AVC2 Sound Limiter
The AVC2 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
limiter is being over driven. Reducing the input level will gently release
the attenuation provided by the AVVC.
