Comelit 6750B

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 controlled, or internal communication can be conducted. 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. In operation, this loop system emits a magnetic alternating field, which generates an electrical voltage in the hearing aid's receiving coil through electromagnetic induction, mirroring the audio signal. This is amplified by the audio amplifier in the hearing aid and transmitted through the earphone to the user's ear. To utilize such induction loop systems, the hearing aid must be equipped with a so-called telephone coil (short: T-coil) that picks up the magnetic alternating field of the induction loop. Typically, when using the telephone coil, the microphone of the hearing aid is deactivated. The Mini Audio Handsfree 6750B 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.
