BVRD2M is an 8 x 8 EN54-16 safety digital matrix with DSP technology. It delivers a maximum of 68 inputs, 87 outputs and 30 messages by adding 5 slave matrices (BVRD2S/LT) directly by internal data link. To create more zones, it's only necessary to add one or some matrix (up to 126) separated or linked with each other in loop by a cooper network, optical fiber or by an IP network (see additional modules). 3 bands parametric aqualization with limiter and levels of bass and treble, 9 bells as one chooses on each input and 10 bands parametric equalization and maximum delay of 1 second on each output, with the configuration software.
