SERIES INSTALLATION AND OPERATION MANUAL
INSTALLATION
Mounting
When rack mounting, it is advisable to allow 1 rack space above and below the
amplifier. When multiple amplifiers are mounted in a rack, exhaust fans should
be used on the rack. Airflow for cooling the AMC30, AMC60 and AMC120 is by
convection from bottom to top. Airflow for cooling the AMC250 is by fan from
front to side.
Direct Output
The output terminal strip accepts wire sizes from 16-22AWG
(1.5mm2 – 0.35mm2) or spade lugs. The following table should be used as a
guideline for cable sizes. Regulations in your area may require different gauged
wire and should be checked before using.

Note:
Only connect one output – either Distributed Line or Low Impedance.
Line Output
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.
REC Output
The REC output wiring
should be kept as short
as possible.
Input Connections
For wiring balanced in, pin 2 is hot.
Unbalanced wiring on the microphone
inputs is not recommended.
Balanced input wiring (shielded pair cable)
is recommended. Unbalanced RCA wiring
should be keep as short as possible.
