Indoor Audio Mini Handsfree (HF) with induction loop, suitable for video systems. For surface mounting, it includes features such as a door opener button, call volume adjustment, and ringtone deactivation. This is indicated by a red LED when the function is active. With the Mini Audio Handsfree, optionally connected relays can be activated or internal communication can take place. Furthermore, the device is equipped with a loop system for hearing aid users, which transmits audio directly to a compatible hearing aid, facilitating communication between the resident and the visitor at the door. During operation, this loop system emits a magnetic alternating field that generates an electrical voltage in the hearing aid's receiving coil through electromagnetic induction, mirroring the audio signal. In the hearing aid, this is amplified by the audio amplifier and directed to the user's ear through the earphone. To use such induction loop systems, the hearing aid must have a so-called telecoil (T-coil) that picks up the magnetic alternating field of the induction loop. Typically, when using the telecoil, the hearing aid's microphone is deactivated. The Mini Audio Handsfree 6750W is compatible with audio-video units Art. 4680C, 1622VCF, 1621, 4681, and 1621VC, and is delivered with component 1214/2C. Dimensions: 105 x 105 x 20 mm.
