  • Page 3 GENERAL The new redesign ILA-1000 represents a loop amplifier as professional solution for the construction of induction loops. The ILA-1000 loop amplifier for audio transmission is used on a large scale, to supply hearing devices by inductive audio signals. The ILA-1000 automatic induction loop amplifier has been developed as high-quality LOOP amplifier for average induction loops.
  • Page 4 60118-4, so that a loop structure according to a „LOOP SEGMENT“ system is possible. In a „LOOP SEGMENT“ system always two ILA-1000 work together which form a magnetic field, thus on the entire area always the constant field strength of the magnetic field is reached.

    Instruction manual SAFETY INSTRUCTIONS Before start-up of the amplifier ILA-1000 we ask you to read the safety instructions carefully. Please carry the installation out according to the following guidelines: In a clearly visible position close to the entrance to the area where an induction loop is installed, a sign „ INDUCTIVE COUPLING“...

  • Page 6: Front Side

    Turn the MLC control to reach the best sound (audio signal) on the induction loop, simultaneously listen to the audio signal with the ILA-E receiver by the headphone. Repeat the measuring process in all ILA-1000 induction loop amplifiers or induction loops bound in the system. 6.- HIGH-EQ filter (+-12dB) LF control of the individual microphone- or LINE inputs.
  • Page 7 Fault indication for loop impedance (impedance is not within the measurement range of 0.5 -3.0 Ohm). IMPORTANT: After eliminating the fault please always „reset“ the loop amplifier ILA-1000“ by switching the amplifier off with the POWER button, wait for 3 sec. and switch it on again with the POWER button.
