PMB-L Merge Box

The PMB-L is a two channel passive line level merge box. Each channel has two balanced XLR/f inputs. The input signal is merged via a resistor network to a XLR/m output. The top side input is transformer isolated. Possible applications might be the routing of two mixing desks to one power amp or mixing a stereo signal down to mono. Our transformer technology allows for an unbalanced top side input to be sent out balanced. There ia a ground lift switch on each channel.
