I. DESCRIPTION: The MP16 amplified monitor is a 16 channel audio level display panel and a selectable (1 of 16 channels)
audio monitor. Ten levels of audio are displayed on a vertical array of colored LEDs (4 green, 1 yellow, 1
red). Each channel has a 3-position level selection switch (0.077, 0.775, and 70.7 volts) on the rear panel.
These are the levels that are nominally displayed at the 0dB LED (factory settings). Level settings for each
channel are user-adjustable over a wide range at an individual trimmer on the front panel. The MP16 is
housed in a 2RU chassis.
