- Page 3 Instruction manual GENERAL The new redesigned ILA-450 is a loop amplifier as professional solution for the installation to loop amplifiers. The ILA-450 loop amplifier for audio transmission is used extensively to supply hearing devices by inductive audio signals. The ILA-450 Phoenix induction loop amplifier has been developed as a high quality LOOP-amplifier for medium induction loops.
- Page 4 The magnetic field outside the intended area quickly loses strength and drops to ZERO. This is done by coupling a phase shift FS-1 which is connected between both ILA-450, which in turn produces a signal phase difference of 90 degrees in the electric current by two adjoining induction loops.
- Page 5 SAFETY INSTRUCTIONS Before starting the amplifier ILA-450 we ask you to read the safety instructions carefully. We ask you to carry out the installation according to the following guidelines: In a clearly visible position a sign „INDUCTIVE COUPLING“ should be placed near the entrance to the area where an induction loop is installed.
- Page 6 Turn the MLC-control to reach the best tone (audio signal) on the induction loop, simultaneously listen to the audio signal with ILA-E receiver via the headphones. Repeat the measurement process for all induction loop amplifiers resp. induction loops ILA-450 which are bound in the system.
- Page 7 0.5 -4.0 Ohm). IMPORTANT: After elimination of the fault please always reset the loop amplifier ILA-450 by switching the amplifier off with the POWER button, wait for 3 seconds and switch it on again with the POWER button.

- Page 13 By the phase modulation the audio signal is shifted by 90 o phases and routed to the second ILA-450, then the second ILA-450 has to supply the second parallel induction loop in the complete system.
- Page 14 LOOP SYSTEM WITH 90 DEGREES PHASE SHIFT according to EN 60118-4 Example for a simple LOOP-SEGMENT induction loop system with two ILA-450 (MASTER/SLAVE) and FS-1 90 degrees phase shifter. It is important that the induction loops are approximately of the same size.

- Page 16 The magnetic field outside the intended area loses quite rapidly strength and drops to ZERO. This is done by coupling a phase shifter FS-1 which is switched between the two ILA-450, this again effects a signal phase difference of 90 degrees in the electrical flow by two adjoining induction loops.
