AMB-5 / SMX-6 IQ Mixer/Multiplexer
3.3 Connect the Audio Wiring (Step 3)
IQ mixer/multiplexers have 6 mic/line inputs and 2
stack inputs (Input 6 of the IQ–AMB-5 is dedicated for
ambient sensing). Two audio channels feed two main
and two auxiliary bus outputs. Three-terminal remov-
able barrier block connectors are provided for the mic/
line inputs and main and bus outputs. RCA-type
phono jacks are provided for the stack inputs. See
Section 5.1 for information on the operation of the
mixer/multiplexer inputs and outputs.
3.4 Connect Auxiliary Devices (Step 4)
Connect any external circuits you plan to use to
control the AUX input and/or monitor the AUX output
of the mixer/multiplexer. See section 5.2 for
information on the operation of the AUX input and
output and for examples of wiring circuits to the AUX
connector.
Important: Provide adequate
cooling if the unit will be used in a
hot environment. It is good prac-
tice to allow one empty rack
space (1.75 inches or 4.4 centi-
meters) between each unit if
more than four units will be
stacked in a cabinet. Each empty
rack space should be sealed with
a blank rack panel to facilitate
proper air flow inside the cabinet.
