Dynamic
Microphone
The left and right line-level outputs from a
mixer feed the inputs of two Mackie TH-12A
Powered Loudspeakers. Their respective THRU
jacks feed the inputs of another pair of Mackie
TH-12A Powered Loudspeakers.
Using a Microphone and the Thru Jack
For microphone connections, you can daisy-chain
up to two TH-12As using the THRU jack, as shown.
Take great care to point any microphones away
from the loudspeakers. Otherwise, feedback may
occur.
