Generally, AMX100 is installed behind the TV, under the conference table, in the cabinet,
etc. However, as AMX100 is the HUB node of each component of the A40 package, it
involves:
The new AMX100 is equipped with a power adapter with a power cord, and a 3-meter USB
cable from USB-B to USB-A.
To connect with ACT10, should buy extra network UTP cable.
To connect with ASP100/110 Speaker, should buy extra speaker cables.
If the conference host terminal/speaker's laptop is far away from the AMX100, then need to
consider purchasing additional USB extension cables or transferring via the ground plug
network.
When connecting with A/V system (audio processor/mixer/handheld microphone receiver)
and hardware video terminals, the AMX100 side will use unbalanced 3.5 audio interfaces
and 6.35 audio interfaces. But the other side is usually a balanced Canon interface and
Phoenix terminal interface. Therefore, additional 3.5/6.35 XLR, 3.5/6.35 Phoenix terminal
and other conversion cables need to be prepared (pay attention to male and female at
both ends).
In addition, due to strong electric magnetic leakage, quality of interconnecting cables,
potential difference between two devices and other factors, unbalanced signals are easily
to get interference and generate current noise. In this case, it is necessary to purchase a
noise eliminator isolator to be connected in series in the interconnection cable to solve the
problem of current noise.
PS: The 6.35mm input port will be designed to balanced type the next batch of production.
Therefore, it is necessary to consider and determine the installation location of the
AMX100 by integrating the above factors.

The AMX100 is equipped with a 20-meter Cat6 network cable as standard, which is used to
connect the first A40.
Each A40 is equipped with a 10-meter Cat6 network cable as standard, which is used to
connect the subsequent A40.
The length of the standard AMX100/A40 network cable can meet the requirements of
common conference room space. If the cable length in the package is not long enough for
some super large conference space, then we can use longer Cat6 and above network
cables (well-known brand). Before using the network cable, the line sequence must be
tested with a line measuring instrument.
As we tested, AMX100 support maximum 8 units of A40 cascaded by 8 20-meter Cat6 net-
work cables with all functions work normally.
A40 is a non-standard PoE power supply mode.The RJ45 port of the AMX100 directly sup-
plies power to multiple A40s, eliminating the need to reserve strong electricity for them in
the ceiling.

Before installation, please prepare suitable screwdriver, scissors or wire stripper in
advance.
Network cable length
ASP110 is equipped with a 25m audio cable as standard. If the length of the standard 25m
audio cable is not enough for the actual customer's conference environment deployment,
you can purchase the audio cable by yourself.
Laying and cabling
The audio cable shall be wired in the pipe slot in the ceiling and wall, and shall not be
wired together with the strong current cable, which is easy to cause electromagnetic inter-
ference and generate current noise.
ASP110 is a wall mounted loudspeaker, passive 4Ω/15W. It is not recommended to use a
third-party speaker. If really need use third-party speaker, it must meet the passive 4
Ω/15W specification.

Phoenix terminal, the left side is positive (+) and the right side is negative (-). The specific
wiring diagram is as follows:

Installation height
ASP110 wall mounted loudspeaker shall be installed as high as possible (if the installation
height can be same with the A40 horizontal height, that will be better). To avoid the pickup
beam range of A40, the loudspeaker shall be as far away from the A40 beam as possible.
Installation angle
ASP110 wall mounted speaker has its own wall mounted parts, which can be rotated left
and right (vertical mounting) to adjust the angle or up and down (horizontal mounting) to
adjust the angle.
When the ASP110 is installed at the same height as the A40, in the vertical mounting
mode, sometimes it is hoped that the audience will have a better voice experience, so
speaker should be tilted downward for sound reinforcement. However, the angle cannot
be adjusted downward in the vertical mounting mode, and other installation accessories
need to be purchased.
The ASP110 speaker should not face to the A40. Especially in the local sound reinforce-
ment scene, the A40 should not be deployed between the ASP110 speaker and the audi-
ence. In that case, the ASP110 speaker is faced to the A40 directly, which is not correct.

For A40, remote conference mode shall be adopted as more as possible. If local sound
reinforcement is necessary, we recommend to use handheld microphone to make
sound reinforcement instead of A40;
The sound reinforcement is on the A/V system side, so the audio output is on the A/V
system side. The A40 package side saves a lot of trouble, such as the subsequent local
sound reinforcement, the audio routing problems when the computer audio and video
material is sharing (under the local conference or remote conference), the current noise

ACT10 is designed with POE technology. When connected to the AMX100, the ACT10
powers on. The corresponding functions of the system can be controlled via the buttons
on the ACT10 (which can be defined on the Nearsync tool).
If the A40 must be integrated with the customer's existing A/V system in the project, it is
recommended that the A40 package only be used as the pickup side, instead of deploying
ASP110 speakers, use the existing speakers in the A/V system for sound reinforcement. The
main considerations are as follows:

3.1 Download and Installation of Nearsync
Sound insulation and noise elimination device is used to eliminate electric current
noise;
Pay attention to the specifications of audio connecting cable connectors, especially
male and female;
Pay attention to the design and planning of audio routing to avoid echo;
Pay attention to the realization of audio flow direction and switching in two scenarios
when audio playback scenario when the audio and video materials on the speaker's
laptop are shared and played: 1, In the local conference (without turn on the conference
terminal); 2, In the remote conference (with the conference terminal holding the remote
conference).
The A40/AMX100 does not support central control, scene configuration switching, and
there is no solution temporarily for complex changing conference room scenarios (such
as switching 3 small conference rooms to one big conference room).
Precautions for A/V system integration are also mentioned in previous chapters, mainly
including:
