sources from Zone 1~4 as Remote
Source Inputs R5 to R8 can be
selected by all zones.
Remote Source R5 is located at
XS1 of Zone 1, Remote Source R6
is located at XS1 of Zone 2, Remote
Source R7 is located at XS1 of Zone
3 and Remote Source R8 is located
at XS1 of Zone 4. Signals of R5 are
mixed with signals of Local Source 1,

INSTALLING THE XOi DIGITAL HOME SYSTEM
1. Prewire
The XOi uses Cat-5 cable for keypad control and either two- or four-conductor 16gauge speaker wire. All the wire is homerun from each zone to the XOi.
2. The XOi digital home systems require Cat-5, unshielded, twisted pair (UTP), for
communication between the keypads/display pads and the main XOi unit. Each end
of the wire is terminated with an RJ45 connector.
The XOi system can accommodate 500 total feet of Cat-5 cable for each zone. For
the most reliable operation, it is best that no single run of Cat-5 exceeds 250 feet.
The correct wiring scheme for the Cat-5 cable is standard EIA/TIA 568A. Properly
terminating the Cat-5 cable is crucial for the operation of the system. It is very
important to use a good quality crimp tool, and testing each end to end run with Cat5 wire tester will insure that your system operate flawlessly, Fig. 1.

Step-by-Step Crimping instructions
Step1 Strip a 2 to 3 inches portion of the insulation, exposing the 4 twisted pairs.
Step2 Untwist the wires and fan them out individually. Arrange the wires into the
correct color scheme as shown in Fig.1
Step3 Flatten the wires in their correct order, and trim them evenly across the top.
Most crimp tools have a wire trimmer built-in. It is best to trim the wires to
about 1/2 in length.
Step4 While holding the wires flat between your thumb and forefinger, insert the
wires into the RJ45 connector, so each is its own slot. Push the wire into the
RJ45, so all 8 conductors touch the end of the connector. The insulation jacket
should extend beyond the crimp point of the RJ45.
Step5 Insert the RJ45 into the crimp tool receptacle and squeeze the tool firmly. Note
that a ratchet type tool should tighten down until it no longer clicks.
Step6 The RJ45 should be firmly crimped to the Cat-5 insulation. It is necessary that
the color scheme be repeated identically on each end of the wire.
3. Speaker Wire Termination at XOi
It is important to keep the proper orientation of positive and negative signal for each
speaker connection. Typically, two-conductor speaker wire uses red to denote
positive and black to denote negative. Some types of wire indicate positive with
dark line running through the insulation. Four-conductor wire can also be used. This
has four separated wires in one outer jacket, making it possible to run a single
speaker wire to a zone for its pair of speakers. This type of wire typically uses red
and black for one speaker and white as positive and green as negative for the
second speaker.

4. Installing the XOi
The XOi is designed to be placed on a shelf or in a component rack. If you are
mounting the XOi with other components,you should remove the feet.
The audio sources are plugged into the four local source inputs on the back panel
of the XOi using stereo RCA cables, Fig.4

5. IR Outputs
The XOi system ships with four IRE1 IR Emitters for transferring IR data from the
keypad receivers (located under the volume button) to the IR receiver on each
piece of source equipment. There are two separated IR output sections on the back
panel. The 38KHz outputs are used for most audio sources. The exception to this is
cable and satellite boxes, which operate at a higher IR carrier frequency closer to
56Khz.It is important that the output being used for each source matches the source
input number. The outputs work individually with each source to allow independent
source control. Simply plug the IRE1 IR emitter into the appropriate IR output on the
back of the XOi and attach the flasher end over the IR receiver of the source
equipment, fig. 5
Fig. 5

6. Keypad XK1 and Zone Setup
The Zone number each keypad XK1 belonging to is decided by which RJ45
connector each keypad connected through Cat-5 cable from JK2 of XK1 to XOi.
EQ Control and Source Grouping
The keypads can be used to set specific zone functions. These are for bass and
treble EQ response and source grouping. To change bass response, press the Mute
button and Source 2 button simultaneously. Adjust the bass level up or down by
using the Volume Up and Volume Down buttons. The Volume indicator LEDs will
indicate the output level, Fig. 7. Adjust treble response using the same process.
This is accessed by pressing the Mute and Source 3 buttons. Once the desired
setting is made, press the Source button again to return the keypad to normal
operation.

Power
Source grouping is a feature that allows multiple zones in an open living space to
always share the same source selection but still retain individual volume and on/off
control. This is achieved by pressing the Mute and Source 4. Volume Up enables
the group function, and Volume Down disable the group function and cause the
keypad to operate independently of all other groups, Fig 8.
Volume Reset
The XOi system keypads automatically reset the listening volume to a low level
when all zones have been turned off and a zone is turned on again.
All off
All the zones in the system can be turned off simultaneously from any keypad by
pushing and holding the power button until the keypad goes completely dark. A
single push and release the power button will only turn that zone off. If another zone
is on, the power button will remain lit.

7. Using the Link Jack to create Eight Zones (This is an optional feature)
Two XOi can be made to react as one using the back-panel 3.5mm connection
labeled "Link". This requires the use of "Y" cables to link the source inputs and IR
outputs. A single mono mini-patch cable is then plugged into the "Link" jack on both
XOi. This links the All Off command so when it is initiated at any of the zone
keypads, all eight zones will turn off.
8. Mute Input and the AMC PDM1 (Phone-Doorbell-Mute Module)
(This is an optional feature)
The back panel of the XOi has a 3.5mm non-shorting stereo connector input labeled
"Mute". This is designed to be used with the AMC PDM1 Phone-Doorbell-Mute
module. When the PDM1 is connected, the system will temporarily mute when the
phone or doorbell rings.

1,2 Doorbell (This is an optional feature)
The back of PDM1 will accept up to two AC or DC voltages from two different
doorbell chimes.
This connection is done with two conductor wire from the terminals on the doorbell
chime to the Doorbell A or Doorbell B inputs on the back of the PDM1, Polarity is
not important for this connection.
3. RJ-11 Connection
Up to two phone lines can be brought into the RJ-11 connection on the back.
The voltage from the phone ringer will trigger the XOi System to mute.
