2. INTRODUCTION
The C Series hearing loop driver range has been designed as high quality digital, networkable
single and dual loop output drivers. The range includes models intended for use with perimeter
loops and multiple loop (MultiLoop™ / Phased Array) designs, with the option to control or access
the unit via a network where required.
An array system provides a solution where a simple loop around the room perimeter will not
work. Arrays are the standard solution for buildings with metal structures or reinforcements, or for
covering large areas. Arrays can also dramatically decrease the ‘spill’ of the magnetic signal outside
of the room, allowing hearing loops to be installed in adjacent rooms, and providing an improved
level of condentiality. Arrays can also be used to change the way two loops interfere with each
other, providing ways of solving even the most complex installation problems.
Depending on a number of factors regarding the installation of the loop and the set-up of the driver,
the C Series can provide compliance with IEC 60118-4 for perimeter loop areas of up to 950m2or
phased array systems up to 3,200m2.
Ease of installation, set-up and operation have been major factors in the design, combined with
optimised performance and the freedom from R.F.I. generation.
The output channels on network equipped C Series models can be congured to be shifted in
phase by 90°, or in phase with each other, allowing the use of array systems or two separate loops
with the same signal, potentially doubling the area coverage.
The C Series drivers have two balanced inputs. These can be congured for microphone or line-
level operation. Input 2 can also be used for 100V line operation.
Dante options are available which adds a third input to the driver.
For more complex installations, you may need ancillary equipment such as microphone pre-amp(s),
adaptor(s), or signal processing units. See Accessories or contact Ampetronic for advice.
The C Series range utilises class ‘D’ drivers; meaning a 60%+ increase in energy eciency over
previous solutions. Drivers feature a graphical user interface with intuitive menus, built in test
signals, and precise audio level adjustments. Networked models are capable of remote control and
monitoring, via email, a browser-based control panel, or standard networking protocols.
All units feature high power outputs plus ample voltage headroom, making them the most exible
solution on the market and suitable for a huge range of applications.
In another rst for high-power Class D Induction Loop drivers, installation can be performed with
total condence, as unique multi-stage ltering ensures compatibility with both other system
equipment and global EMC regulations. Networked C Series models also boast dual-slope metal
loss compensation that caters for a wide range of metal loss frequency characteristics.
