AMIS480P 4 x 80 WATT LINE AMPLIFIER INSTALLATION AND OPERATION MANUAL
INTRODUCTION AND CONTENTS The Australian Monitor Installation Series AMIS480P is a robust, highly featured 4 channel power amplifier. Offering 4 independent channels, each delivering 80 watts into 4 ohms or 70/100 volt line, the AMIS480P is designed to operate in extreme conditions to give the contractor the most reliable 4 channel amplifier available today.
FRONT PANEL 1 2 1 STATUS This LED indicates OUTPUT signal level for each channel. Green: -23dB (below rated power) Red: 0dB (rated power, clip) Due to the nature of distributed audio and line transformers, this LED functions as a peak indicator. Some flashing of red is acceptable on program transients. Continuous flashing of red could be placing undue stress on the amplifier due to external speaker transformer saturation.
BACK PANEL 1 2 3 1 IEC MAINS INPUT SOCKET This is a standard IEC 3 pin socket. It accepts a standard IEC mains cable, provided. The fuse draw contains the mains fuse and a spare. The mains fuse is: • 230V/240V model Time lag (slow 6.3A blow) HRC 20mm x 5mm ceramic type. • 115V model Time lag (slow 10A blow) HRC 20mm x 5mm ceramic type. Always replace the fuse with one of the same value and type. NOTE: Always disconnect power to the amplifier before replacing fuses.
INSTALLATION MOUNTING When rack mounting, allow at least 45mm (1.14”) between the sides of the amplifier and the sides of the rack. The front of the amplifier should be left clear and free to draw air. Airflow for cooling the amplifier is front to rear. INPUT CONNECTIONS When wiring balanced in, pin 2 is hot. When wiring unbalanced in, pin 2 is hot and pin 1 and pin 3 should be shorted together to the shield. Balanced input wiring (shielded pair cable) is recommended.
SETUP & TROUBLESHOOTING SETUP Each channel of the AMIS480P can be wired individually to suit multizone systems. If more than one zone is to receive the same signal, it can be easily routed to the next channel of the amplifier using the LINK switches. The channel being linked receives the input signal from the previous channel. The previous channel may be receiving signal from its own input or the signal coming from the previous channel.
