SPLtrack is a noise level measuring system with the ability to present information
in real time using a web interface.This allows it to be viewed on any computer
with a compatible web browser either locally to the SPLtrack device or via the
Internet.
The system consists of a server computer linked to any number of metering units
via a local area network (LAN) and to the Internet via a wide area network
(WAN).
Each metering unit has a CCCP microphone that conforms to
BS 61672 part 3: Class 1.
The metering units are powered through the LAN cable (PoE) and can therefore
be easily installed at optimal locations.
Please read the following document carefully and familiarise yourself with the
operation of the product before using. Keep this document to hand so that you
can refer to it if necessary.

5. Installation of E-Shield
This manual does not presume to give advice on
suitable locations for E-Shield.The rules for installation
height, proximity to other objects etc must be
respected.
the bottom cap is fitted with a 3/8”UNF threaded
hole suitable for attachment to microphone stands
and professional camera threads. A 1/4”UNF adapter
is also provided for smaller diameter camera tripods.
E-Shield is designed for plumb vertical installation with
the bird spike uppermost.This position ensures
correct polarisation for the microphone and optimum
weather protection.
WARNING: Installation other than in the
vertical orientation described can result in
damage to the microphone due to water ingress.
Ensure that the tripod or other support device is
stable. Be aware that the windShield presents a
considerable profile to the wind and can result in
unexpected overturning forces.Where possible
always peg the feet of tripods or use a stage weight as
an anchor.
Place the windshield over the E-shield with the rubber gasket uppermost and
push downwards gently until the gasket grips firmly on the taper of the bird spike.
it is important that the gasket seals properly. Any damage to the edge of the
gasket or the surface of the bird spike can result in rainwater reaching the
microphone. In this case replace the gasket and/or the bird spike before use.
The manufacturers do not accept any liability for damage to microphones of any
type caused by the assembly or use of this product.
Calibration
The bird spike and the windshield can be removed as one assembly by
unscrewing the bird spike. this presents the microphone capsule ready for
application of a hand-held calibrator. After calibrating the bird spike and
windshield can be replaced as one. take care not to over-tighten.
