Preamplifier for connecting a microphone and a line sound source, e.g. a CD or MP3 player. Suitable for residential buildings, small training rooms, medical practices, etc. The volume of the two sound sources can be controlled separately. The preamp UP can also be switched on/off. The pre-amplified signal can then be passed on to up to 50 AMP 10 (DC) units - or e.g. to a 100V amplifier. The metal support plate is screwed onto a standard flush-mounted box with a depth of 63 mm. A printed cover plate measuring 50x50 mm is included in the delivery. A corresponding adapter frame for the respective switch range is available from electrical wholesalers.
