INSTALLATION

This section contains several diagrams which shows many, but by no means all, of the ways to connect the RE 27 into a

sound reinforcement or monitor system. Whatever your particular application, it is helpful to realize that the RE 27 is
actually two independent products in one: an equalizer with input(s) and output(s), and a realtime analyzer with a mic input
and pink noise output.

MAIN SPEAKER EQUALIZATION

IMPORTANTNOTES:

1. See page 3 or Rane Note 110 for connector wiring.

2. To drive both left and right amplifier channels from a single RE 27 Output, use a “Y” connector to split the RE 27

Output to both left and right inputs of the amp or crossover. 

(NOTE: If you have the good fortune to be using a Rane AC 

series crossover , you need only connect the single RE 27 Output to the Channel 2 input of the crossover - both left and

right outputs will automatically be driven internally to eliminate the need for a “Y” connector.)
