INTRODUCTION AND CONTENTS The Australian Monitor AMC+ Mix mixer takes the affordability and ease of use of our AMC+ series amplifiers and integrates the front end into a low cost mixer for applications where reliability is everything, but the more elaborate features of larger mixers are not required. The AMC+ Mix is a 1 RU mixer with 3 universal mic/line inputs.
front PANEL 1 2 3 4 5 6 1 CH 1–4 These control the levels for each channel input. 2 Bass There is 12dB of cut and boost at 100Hz. 3 Treble There is 9dB of cut and boost at 10kHz. 4 Master This controls the overall mixed output level. 5 On This LED indicates the unit is powered “on”. 6 Power This switch switches power on or off from the mains. The up position is on.

RCA input – This is an unbalanced line level input. It has an input sensitivity of 150mV. The two RCA sockets are summed to mono internally. 3 2 1 3 Line Output The LINE output is on a balanced XLR connector. The output level is 1V into 1k at rated output.
installation OUTPUT CONNECTIONS Rec Output Line Output The TAPE output wiring should be kept as short as possible. Typically less than 3m. The LINE output XLR can be used to connect up to 6 booster amplifiers. Balanced wiring (shielded pair cable) is recommended. NOTE: When wiring the LINE output as unbalanced, Pin2 should be wired as hot and Pin1 should be wired as ground/shield. Do not wire Pin3. Input Connections For wiring balanced in, pin 2 is hot.
