Indoor station Audio Mini Handsfree (HF) with induction loop, suitable for video systems. For surface mounting including the following functions such as a door opener button, setting the ring volume and ring tone muting. This is indicated by a red LED when the function is active. With Mini Audio Handfree, relays connected to the system can optionally be switched or internal communication can be conducted. The device is also equipped with a ring line for hearing aid wearers, which transmits the audio directly to a suitable hearing aid and makes it easier for the resident to communicate with the visitor at the door. During operation, this ring line emits an alternating magnetic field which, through electromagnetic induction, generates an electrical voltage in the receiving coil of the hearing aid, the course of which is the same as that of the audio signal. In the hearing aid, this is amplified by the audio amplifier and passed to the wearer's ear via the earpiece. In order to use such induction loop systems, the hearing aid must have a so-called telephone coil (short: ""T-coil""), which absorbs the alternating magnetic field of the induction loop. The hearing aid's microphone is usually deactivated when the telephone coil is used. Mini Audio Handsfree 6750W is compatible with the audio-video units Art. 4680C, 1622VCF, 1621, 4681 and 1621VC and is supplied with the component 1214/2C. Dimensions: 105x105x20mm.
