IN400
AV SWITCHING AMPLIFIER
INSTALLATION AND OPERATION MANUAL

1. Save the carton and packing material even if the equipment has
arrived in good condition. Should you ever need to ship the unit, use
only the original factory packing.
2. Read all documentation before operating your equipment. Retain
all documentation for future reference.
3. Follow all instructions printed on unit chassis for proper operation.
4. Do not spill water or other liquids into or on the unit, or operate
the unit while standing in liquid.
5. Make sure power outlets conform to the power requirements listed
on the back of the unit.
6. Do not use the unit if the electrical power cord is frayed or broken.
The power supply cords should be routed so that they are not likely
to be walked on or pinched by items placed upon or against them,
paying particular attention to cords and plugs, convenience
receptacles, and the point where they exit from the appliance.
7. Always operate the unit with the AC ground wire connected to the
electrical system ground. Precautions should be taken so that the
means of grounding of a piece of equipment is not defeated.
8. Mains voltage must be correct and the same as that printed on the
rear of the unit. Damage caused by connection to improper AC voltage
is not covered by any warranty.
9. Have gain controls on amplifiers turned down during power-up
to prevent speaker damage if there are high signal levels at the inputs.
10 Power down and disconnect units from mains voltage before making
connections.
11. Never hold a power switch in the “ON” position if it won’t stay
there itself!
12. Do not use the unit near stoves, heat registers, radiators, or other heat
producing devices.
13. Do not block fan intake or exhaust ports. Do not operate equipment
on a surface or in an environment which may impede the normal flow
of air around the unit, such as a bed, rug, weathersheet, carpet,
or completely enclosed rack. If the unit is used in an extremely dusty
or smoky environment, the unit should be periodically “blown free”
of foreign matter.
14. Do not remove the cover. Removing the cover will expose you
to potentially dangerous voltages. There are no user serviceable
parts inside.
15. Do not drive the inputs with a signal level greater than that required
to drive equipment to full output.
16. Do not connect the inputs / outputs of amplifiers or consoles to any
other voltage source, such as a battery, mains source, or power supply,
regardless of whether the amplifier or console is turned on or off.
17. Do not run the output of any amplifier channel back into another
channel’s input. Do not parallel- or series-connect an amplifier output
with any other amplifier output. Australian Monitor Inc is not
responsible for damage to loudspeakers for any reason.
18. Do not ground any red (“hot”) terminal. Never connect a “hot” (red)
output to ground or to another “hot” (red) output!
19. Non-use periods. The power cord of equipment should be unplugged
from the outlet when left unused for a long period of time.
20. Service Information Equipment should be serviced by qualified service
personnel when:
A. The power supply cord or the plug has been damaged.
B. Objects have fallen, or liquid has been spilled into the equipment
C. The equipment has been exposed to rain
D. The equipment does not appear to operate normally, or exhibits a
marked change in performance
E. The equipment has been dropped, or the enclosure damaged.

RS485 Setup
The IN400 data port is an RS485 serial data port. Twisted pair cabling should be used when connecting
RS485 devices, such as CAT3, CAT5, CAT5e or CAT6 UTP cabling. RS485 data networks should be wired
in a ‘daisy chain’ configuration with a maximum of 32 devices in the chain. The IN400 is not terminated
so may be inserted anywhere in the data network. If the IN400 is being used at the end of a chain,
a 120ohm (characteristic impedance of UTP) terminating resistor should be connected between
the + and - connections.
The IN400 has built in failsafe bias circuitry so there are no need for external biasing resistors.
The maximum length of the chain is 500m.
Global Mode
When the IN400 is in global mode, changes to the volume and tone affect all the sources.
When not in global mode, changes to the volume and tone affects the selected source.

PAGE 7IN400 INSTALLATION AND OPERATION MANUAL
INSTALLATION
POWER CONNECTION
Ensure the mains voltage supply matches the rear of the IN400 (+/- 10%)
Ensure that all system grounds (earth) are connected to a common point. Avoid
powering equipment within a system from multiple power sources that may be
separated by large distances. This will eliminate ground loops that are heard as
50/60Hz humming or buzzing in speakers and seen as moving or stationary bars
on video equipment.
INPUT CONNECTIONS
Audio
All the inputs are unbalanced RCA sockets. Unbalanced RCA wiring should be
keep as short as possible. Typically less than 3m.
Video
Video inputs are on either unbalanced RCA sockets (composite) or 15 pin high
density female connectors D-connectors (VGA). The maximum cable length for
composite video is typically less than 3m for shielded wire and 10m for coaxial
before signal degradation. This will depend on the cable quality.
OUTPUT CONNECTIONS
Audio
The line level outputs are unbalanced RCA sockets. Unbalanced RCA wiring should
be keep as short as possible. Typically less than 3m.
The amplifier outputs are 5.08mm pluggable connectors. Use the following table
for selecting a suitable guage wire for the cable you are running over a particular
distance. The table is for a 1dB drop in level which is generally considered
acceptable.
OUTPUT CONNECTIONS (cont.)
Video
Video outputs are on either unbalanced RCA sockets (composite) or 15 pin high
density female connectors D-connectors (VGA). The maximum cable length for
composite video is typically less than 3m for shielded wire and 10m for coaxial
before signal degradation. This will depend on the cable quality.
There are two composite outputs for running to 2 different monitors without the
need for an external distribution amplifier.

The RS485 data port is on a 5.08mm pluggable connectors. Twisted pair cabling
should be used When connecting RS485 devices, such as CAT3, CAT5, CAT5e
or CAT6 UTP cabling. RS485 data networks should be wired in a ‘daisy chain’

The maximum length of the chain is 500m.
All installation work should be done with the power disconnected. The following inforamtion will help with installation. After installation is complete power up all the
sources before turning on the IN400.
Do not connect a total impedance of less than 4ohm per channel.
