They allow control of the volume with, respectively, 4 positions + off for MURA 305, and 11 positions + off for MURA 310/330/360. The max. nominal powers range from 2.5W to 30W in case of 70V lines; and 5W to 60W for 100V lines. Each position attenuates the overall level from 5dB to 10dB, depending on the model. However, all they provide, in addition to the normal 70-100V audio line, the 70-100V auxiliary line at maximum level (the attenuation does not operate in this case but passes the whole signal to the speaker) and the 24V relay input for switching between normal and auxiliary line in case of alarm. The MURA 3 Series is supplied with a front cover plate (white) and is compatible with BTicino® Matix® 3P plates.
