

Take care to prevent damage to the power cord. Do not allow it to become
crimped, pinched, walked on, or become tangled with other cords. Ensure that
the power cord does not present a tripping hazard.



Never unplug the unit by pulling on the power cord. Always grasp the connector
head or adapter body.



Ensure that power is turned off and disconnected before making any electrical
connections.



Clean using a soft, dry cloth only. Do not use chemical cleaners, solvents, or
detergents. For stubborn deposits, moisten the cloth with warm water.



This device has no user serviceable parts. Do not attempt to open, service, or
modify this device.



If using this amplifier to drive a 70V or 100V speaker array, ensure that the total
wattage rating of the speaker array does not exceed 80% of the amplifier's rated
RMS power level, i.e., 48 (18803), 96 (14886), or 192 (18805) watts, depending on
model



Because high voltage is present on the 70V and 100V speaker output terminals,
always use the included terminal cover to prevent electric shock from accidental
contact.

INTRODUCTION

Thank you for purchasing this 5-Channel 70V/100V Mixer Public Address Amplifier!
This amplifier features three microphone inputs and two auxiliary inputs, each of which
is active and mixed into the line and speaker level outputs. When an EMC input trigger
is detected, all outputs except MIC 1 are muted, allowing for the clear broadcast of
important messages. The amplifier can drive a speaker array consisting of one or more
speakers presenting a 4~16 ohm load or to one or more 70V or 100V speakers
connected in parallel as part of a large public address system.
