How It Works - Usl MMP-10 Instruction Manual

MMP-10 I
The MMP-10 contains four high quality microphone pream-
plifiers, followed by an adjustable switching circuit. Micro-
phone signals are routed through the unit in several different
configurations.
On powerup, only microphone one is amplified and routed
through the MMP-10 to your analyzer.
The remote switch at the analyzer end of the MMP-10 cable
permits selection of other microphones. Pressing the switch
once selects microphone two. Press it again and microphone
three is selected; once more and microphone four is selected.
Pressing it once again starts automatic scan mode, which
cycles through all four microphones, one at a time. Pressing it
one more time resets the MMP-10 to microphone one.
Typical analyzer equipment is shipped with only a single
microphone. The MMP-10 allows you to expand your equip-
ment to four microphones. [Such multi-microphone measure-
ment techniques achieve far superior acoustical results in
auditoriums due to the averaging effect.]
