d&b audiotechnik AMP-L P1200 Amplifier Controller Card

This item is used but fully functional.

When used in a d&b audiotechnik P1200 amplifier, this card provides a linear output of the amplifier channel to power any non d&b audiotechnik loudspeaker.  This card can also passively power d&b MAX wedges.  Two cards are needed to take advantage of each amplifier channel.
