REMOTE CONTROL

1. Prewire
The XO uses Cat-5 cable for keypad control and either two- or four-conductor 16-
gauge speaker wire. All the wire is homerun from each zone to the location of
ZT8 that normally located behind XO and hooked to XO via short SCSI cable.
2. The XO digital home systems require Cat5, unshielded, twisted pair (UTP), for
communication between the keypads/display pads and the main XO unit. Each end
of the wire is terminated with an RJ45 connector.
The XO system can accommodate 2000 total feet of Cat5 cable. For the most
reliable operation,it is best that no single run of Cat5 exceeds 250 feet.
The correct wiring scheme for the Cat5 cable is standard EIA/TIA 568A. Properly
terminating the Cat5 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.

Note: Colors listed as "stripe" are a white wire
with a colored stripe.

Step-by-Step Crimping instructions
Step1 Stripa2to3inch 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 Cat5 insulation. It is necessary that
the color scheme be repeated identically on each end of the wire.
3. Speaker Wire Termination at ZT8 (8 Zone Terminal)
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. ZT8
Both the speaker wire and Cat5 cables for each zone terminate into the back side of
the ZT8. The order of Cat5 plug-ins is irrelevant to the operation of the system,but it
is recommended that you label the individual Cat5 cables for future references.
Follow the zone and polarity labeling for speaker wire termination, Fig. 2
The final connections from ZT8 is made with the SCSI cables supplied with XO Digital

5. Installing the XO
The XO is designed to be placed on a shelf or in a component rack. If you are
mounting the XO with other components,you should remove the feet.
The audio sources are plugged into the four source inputs on the back panel of the
XO using stereo RCA cables, Fig.4
6. IR Outputs
The XO 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 XO and attach the flasher end over the IR receiver of the source equipment,

7. Keypad XK and Zone Setup
EQ Control and Source Grouping
The Zone number each keypad XK belonging to is decided by which RJ45
connector each keypad connected through CAT5 cable from JK2 of XK to ZT8.
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 1 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 2 buttons. Once the desired setting is
made, press the Source button again to return the keypad to normal operation.
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 3. 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.
The XO 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. If a zone is
turned off and turned back on before all the zones are turned off, it will return at
previous volume level.
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.

8. Using the Link Jack to create Sixteen Zones
9. Mute Input and the AMC PDM1 (Phone-Doorbell-Mute Module)
Two XO 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
XO. This links the All Off command so when it is initiated at any of the zone
keypads, all sixteen zones will turn off.
The back panel of the XO 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
3. RJ-11 Connection
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.
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 XO System to mute.

(APPLIES TO TUNERAND RECEIVERS ONLY)
An outdoor antenna should be located away from power lines.
(APPLIES TO TUNERAND RECEIVERS ONLY)
If an outside antenna is connected to the receiver, be sure the
antenna system is grounded so as to provide some protection
against voltage surges and built up static charges.
Section 810 of the National Electrical Code,ANSI/NFPA No.
70-1984, provides information with respect to proper
grounding of the mast and supporting structure, grounding of
the lead-in wire to an antenna discharge unit, size of grounding
conductors, location of antenna-discharge unit, connection to
grounding electrodes, and requirements for the grounding
electrode. See Figure.
a) Use No. 10 AWG (5.3 mm ) copper, No. 8 AWG (8.4 mm )
aluminum, No. 17 AWG (1.0 mm ) copper-clad steel or
bronze wire, or larger, as a ground wire.
b) Secure antenna lead-in and ground wires to house with
stand-off insulators spaced from 4-6 feet (1.22-1.83 m)
apart.
c) Mount antenna discharge unit as close as possible to where
lead-in enters house.
d) Use jumper wire not smaller than No.6 AWG (13.3 mm )
