Hearing Loop System Types

Hearing Loop System Types

There are 6 basic types of loop layout for an audio induction loop system:

overspill_counter_loop 
Overspill (counter) loop
Powered by one, small amplifier, overspill or counter loops work best for one-to-one communications at counters, reception desks and intercoms.

 

perimeter_loop
Perimeter loop

Powered by as little as a single amplifier, the perimeter loop is used for area coverage, in spaces up to 25m wide with NO METAL LOSS and spaces up to 2-6m with metal loss. Installers should allow for spill up to 4x width away.

 

single_array_loop
Single array

Powered by as little as a single amplifier, the single array is used for areas with metal loss that are wider than 2-6m (maximum). Ideal for fixed seating areas, for example a theatre or classroom.

 

cancellation_loop
Cancellation loop

Powered by as little as a single amplifier, cancellation loops are the solution for areas suitable for a perimeter loop, but where spill control is required on one side only. A good example of this scenario would be adjacent classrooms.

 

phased_array_loop
Low loss array

Powered my multiple amplifiers, a low loss array is appropriate for large areas in excess of 25m wide with metal loss. An example of a situation that would benefit from a low loss array system is balconies in theatres.

 

low_spill_phased_array_loop
Ultra-low spill array

Powered my multiple amplifiers, an ultra-low spill array is ideal for adjacent rooms that require full confidentiality or with nearby, interfering systems. Suitable for large areas in excess of 25m wide with metal loss.
