XLR Audio Input and Parallel Output
The ACM250P includes both male and female 3 pin XLR connectors. While the female is normally used as the input
to the amplifier, both XLR’s are connected in parallel so either will work. When signal is connected to one XLR, the
other XLR becomes a line level output allowing the input signal to be distributed (split) to other amplifiers. In some
projects, the same input may be looped through to multiple amplifiers using this method. Up to 6 amplifiers can be
looped together without any noticeable loss in level. A distribution amplifier should be used when more than 6
amplifiers need to be looped.
The XLR’s are wired as follows: Pin 1: Shield. Pin 2: Hot, +, Positive. Pin 3: Cold, -, Negative
