Ancillary hearing loop equipment by Ampetronic
To facilitate the implementation of complex loop designs such as those required for very large area coverage, spill control, metal loss compensation or balcony coverage, Ampetronic provide a range of ancillary equipment including:
- CTU11/12 Current ratio transformer
If you don’t need more power output, but you need more current or voltage, a current ratio transformer – the CTU11 or CTU12 – can be used with an ILD1000G to optimise the amplifier output to your application. The CTU11 Current Ratio Transformer can often be used where the voltage or current demands of a loop would normally exceed the capabilities of the ILD1000G loop driver. - ILC4 combining unit
The ILC4 is integral to Ampetronic’s Parallel drive™ technology and is designed to hold up to 4 ratio transformers. The unit is designed to sum the output currents of multiple loop drivers to cope with high current and voltage loop demands. The units are factory configured to match the loop amplifier(s) with the actual loop impedance for maximum efficiency. This enables very large areas to be covered; it can also be used with loop applications where very high metal loss is expected. Using the parent – child system found on our professional loop driver product range, areas up to 4000 m² (43000 ft²) can be successfully covered. - SCC signal connection cables
The cables allow connection from an audio source on a 3.5mm stereo jack socket such as a headphone output commonly found on most portable audio devices and laptops. They are intended to interface to a wide range of typical inputs and provide appropriate attenuation where applicable. - Wireless kit
The Ampetronic Wireless Kit is a pre-selected and tested set of components designed to easily and quickly enable a network access point during testing and commissioning of networkable Drivers.The kit can be used in various scenarios where a LAN is either not available, not convenient, or where security protocols prevent access to it when setting up a Hearing Loop system.
Ampetronic often design Audio Induction Loop Systems that are more complex than the simple ‘wire-around-wall’ installations when customers require specialised systems or have demanding specifications to meet. These systems vary from very large area requirements such as cathedrals, sports halls, etc. to irregular-shaped areas, loop systems requiring low-spillover for confidentiality, or proximity to other induction loops. Modern buildings often incorporate large amounts of metal in their structures, and the frequency dependent losses caused by this require special attention. For many of the special situations listed above, and others, Ancillary hearing loop equipment by Ampetronic enables these requirements to be met with essentially ‘standard’ units. For the majority of situations, these units are set up in the factory for a particular location, and this is part of our design support work.
