Dear Rep,I have a piece of equioment that I believe is an amplifier or an attenuator. It is a part of an older paging system. The item itself is a LX-10C and is from McMartin Industries, Inc. Do you have any knowledge of this piece of equipment? If so, I would like to purchase the same model or any other device that would be compatible.Thank you for you time,Donnie Ussery
