Counter Loop Kit. This is a complete kit for applications where there is no amplified audio system present. A 12” Nylon Fabric Mat (containing a two-turn loop with resistor) is installed under any non-metal counter, and produces about a 36” x 36” magnetic field for T-Coil equipped hearing aid users.
Applications include: Kiosks, Pharmacies, Bank Teller Windows, Ticket Windows, or any application where close-range hearing assistance (via hearing aid T-Coil) is desired. Can also be used as a portable system for meetings as a chair loop or other creative applications.

2 x Microphone inputs. 3.5 mm mono jack plug. DC powered 5 V for Electret Microphones.
2 x Aux In Left/Right Line Inputs. Phono/RCA jacks. For direct connection to a TV sound output or other sound source via SCART or other suitable jack.
Push grip connectors for loop cable (labelled: “loop cable”). Loop will give full output with loop resistance between 0.5 and 1.5 ohms.
3.0 A output current @ 100 Hz - 5 KHz. Meets BS EN60118-4: 2006 for a loop not exceeding 6.5 m (20 ft) in width. Suitable for areas up to 540 sq. ft (50 m2).
Single turn loop cable. System supplied with 40 m (130 ft) of 24 ga/0.2 mm (0.75 mm2) single core PVC insulated cable. Min cable length 36 ft (11 m) = 0.5 ohms.
The counter loop system is installed underneath a non-metal surface such as a countertop, kiosk or desk. The speaker's voice is picked up by the microphone, amplified by the loop amp and transmitted through the loop mat via magnetic field to the t-coil in the listener's hearing aid.
When used in under-the-counter applications (e.g., a bank teller window) the mat is mounted in the upper front corner of the cabinet, with half of the mat facing up, and half facing forward as shown in the illustration. This generates a uniform field about 36" x 36" around the listener, easily picked up by the hearing aid.
