The MLA-6 and MLA-8 are microphone mixers with six and eight audio inputs and one audio output 
respectively. They are  designed to combine up to six and eight microphones (or up to four 
speaker/microphones) to expand the listening area of an audio zone.  The MLA-8 is located between the 
microphones (or speaker/microphones) and the Louroe base station.  In addition, it has a line driver amplifier 
that allows for runs up to 5,000 ft. between the MLA-8 and the Louroe base station and up to 1,000 ft. between 
the MLA-8 and the remote microphone (or speaker/microphone) for a total of 6,000 ft
