Leading Loop Installers
WHY HAVE PRINTACALL INSTALL YOUR LOOP SYSTEM?
Printacall has over 25 years of research and development of loop design and installation with the objective of providing hearing impaired people with correctly functioning loops.
OUR TECHNIQUES INCLUDE THE FOLLOWING:
We check the client's end uses, size of the hall, ceiling height, building construction, metallic influences and background magnetic fields.
DESIGN & EQUIPMENT
Our amplifiers are purpose built loop drive modules and incorporate a Limiter/Compressor Module, specifically configured for hearing impaired users.
On installation, we set the level of the compressor for a softly spoken person. Any person speaking or music above this level will come through the loop system at the same volume as the softly spoken person.
The Hearing Aid "T" switch can pick up magnetic interference caused by electrical sub-stations, some dimmers and some electrical cabling.
In most cases this can be improved by boosting the level of the loop, thus improving the signal to noise ratio.
Also note that electric guitars may pick up the loop signal. Should you expect this to be a problem, please contact Printacall to discuss solutions.
Our installation procedures include a consideration of aesthetics. We spare no reasonablepractical effort to ensure wires are concealed. Where possible, we prefer to mount the loop drive amplifiers in a secure place to avoid tampering and all controls are preset.
We adjust, tune and test the installation and circuitry to theoretical and practical standardsusing modern equipment and check the actual audio-magnetic fields overthe area of the loopwith modern engineered audio inductive field strength testers.
We provide A4 signs with the international "ear" symbol to notify the hearing impaired of the presence of a loop. These are supplied at all our installations at no charge.
Loop Receivers are extremely useful for testing the integrity of the Hearing Loop and are also available for those people who do not have the "T" switch" to gain the advantages of the loop.
