to ensure reliable operation of the product and to protect it from overheating.
These openings must not be blocked or covered. The openings should never be
blocked by placing the product on a bed, sofa, rug, or other similar surface. This
product should not be placed in a built-in installation such as a bookcase or rack
unless proper ventilation is provided or the manufacturer’s instructions have been
adhered to.
• Power Sources - This product should be operated only from the type of power
source indicated on the marking label and connected to a MAINS socket outlet
with a protective earthing connection. If you are not sure of the type of power
supply to your home, consult your product dealer or local power company.
• Power-Cord Protection - 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 at plugs, convenience receptacles, and the
point where they exit from the product.
• Mains Plug - Where the mains plug or an appliance coupler is used as the
disconnect device, the disconnect device shall remain readily operable.
• Outdoor Antenna Grounding - If an outside antenna or cable system is
connected to the product, be sure the antenna or cable system is grounded so
as to provide some protection against voltage surges and built-up static charges.
Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information
with regard 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.
NOTE TO CATV SYSTEM INSTALLER
This reminder is provided to call the CATV system installer’s attention to Section 820-40 of
the NEC which provides guidelines for proper grounding and, in particular, species that
the cable ground shall be connected to the grounding system of the building, as close to
the point of cable entry as practical.
• Lightning - For added protection for this product during a lightning storm, or
when it is left unattended and unused for long periods of time, unplug it from the
wall outlet and disconnect the antenna or cable system. This will prevent damage
to the product due to lightning and power-line surges.
• Power Lines - An outside antenna system should not be located in the vicinity
of overhead power lines or other electric light or power circuits, or where it can
fall into such power lines or circuits. When installing an outside antenna system,
extreme care should be taken to keep from touching such power lines or circuits
as contact with them might be fatal.

• All eight LINE INPUT LED indicators will turn red for about 10
seconds, briey all blue and then blue for those LINE INPUT
channels with active line input signal or no light (except Standby
LED) in the absence of any active line input signal. The 10 seconds
delay in powering up is intended for system power stability and
security self-check.
3 LINE INPUT (1 – 8) LED INDICATORS
• LINE INPUT channels with active source or input signal will
have their corresponding front panel LINE INPUT LED indicators
illuminated in blue.
• If there is no active source or input signal connected to a particular
LINE INPUT, the corresponding front panel LINE INPUT LED indicator
will not light up.
• Pressing the Power button again turns the unit back to standby
mode. The Standby LED indicator will turn from blue to amber.

• Use RCA-to-RCA leads to connect Audio Output terminals from
compatible external devices such as preampliers, processors or other
applicable devices to GLOBAL A IN and/or GLOBAL B IN terminals.
• If GLOBAL A and/or GLOBAL B are turned ON in the web-based
CI 8-120 User Interface, the source(s) connected to GLOBAL IN
terminals will become the active input defeating all other active line
input channels.
• GLOBAL A takes priority over GLOBAL B.
GLOBAL A OUT, GLOBAL B OUT
• Use RCA-to-RCA leads to connect GLOBAL A and/or GLOBAL B OUT
terminals to audio INPUT terminals of compatible external devices
such as ampliers, receivers or other applicable devices.
• The GLOBAL OUT terminals are line level “loop through” output. The
same level of input signal from corresponding GLOBAL IN is available at
the corresponding GLOBAL OUT terminal thereby allowing the same
signal to be shared or passed on to another amplier.
• At standby mode, line level “loop through” output at GLOBAL A
OUT and GLOBAL B OUT terminals remain available as long as the
sources for GLOBAL A IN and GLOBAL B IN are active.

corresponding Audio Output terminals of compatible external
devices such as preampliers, processors or other applicable
devices.
• Congure LINE INPUT 1-8 via INPUT/OUTPUT menu of the webbased CI 8-120 User Interface. Each LINE INPUT source can be
assigned to a specic or multiple speaker OUTPUT channel(s).
• The LINE INPUT ports are numbered 1 to 8. LINE INPUT channels with
active input signal will have their corresponding front panel LINE INPUT
LED indicators illuminated in blue. If there is no active input signal
connected to a particular LINE INPUT, the corresponding front panel
LINE INPUT LED indicator will not light up.
6 SPEAKERS (1 - 8)
• Connect external speaker cables to supplied SPEAKERS terminal
block ensuring that the connections match CI 8-120's SPEAKERS
terminal markings.
• To illustrate, connect CI 8-120 SPEAKERS “1+” terminal to
corresponding “+” terminal of your external speaker and “1-”
connected to external speaker’s “-” terminal. Follow the same
connection conguration when connecting other external speakers
to SPEAKERS terminals “2+” and “2-” up to “8+” and “8-”.
• After installing the external speaker cables to the supplied SPEAKER
terminal blocks, plug in the wired up SPEAKER terminal blocks to
corresponding SPEAKERS (1- 8) rear panel terminals of CI 8-120.

7 +12V TRIGGER IN
+12V TRIGGER IN – ON/OFF
• This dual function switch alternates between sensing a +12V input
as applied through the +12V TRIGGER IN and defeating +12V
TRIGGER IN.
• At ON setting and with the +12V TRIGGER IN of CI 8-120 connected
to a compatible external device that is equipped with a +12V DC
trigger output, the CI 8-120 can be switched remotely from standby
mode to operating mode and vice-versa. This is dependent upon
the presence or absence of +12V DC supply at +12V TRIGGER IN
(refer also to item about +12V TRIGGER IN +/-).
• With +12V TRIGGER IN-ON/OFF switch set to ON, the CI 8-120
cannot be powered from standby to operating mode and viceversa. The function of powering up/down the CI 8-120 is handled
by the compatible external device where +12V TRIGGER IN is
connected.
• +12V TRIGGER IN is disabled when +12V TRIGGER IN - ON/OFF
switch is set to OFF. This is the default setting and allows the
CI 8-120 to power up normally.
+12V TRIGGER IN +/-
• Use the supplied 12V TRIGGER terminal block to connect +12V
TRIGGER IN +/- terminals to corresponding terminals of compatible
external +12V TRIGGER source. Install the wired up 12V TRIGGER
terminal block to CI 8-120’s +12V TRIGGER IN +/- rear panel terminal.
• The +12V TRIGGER IN allows the CI 8-120 to be remotely switched
from standby mode to operating mode and vice-versa by the
external controlling device where +12V TRIGGER IN is connected to.
The external controlling device, such as compatible preampliers,
integrated ampliers, receivers, etc., must be equipped with +12V
trigger output to use this feature.
• Refer also to the item about “12V TRIGGER- ON/OFF”.
8 LAN
• LAN connection must be setup for wired connection to be
established. Set up a Wired Ethernet broadband router with
broadband internet connection. Your router or home network
should have a built-in DHCP server to consummate the connection.
• Using a standard straight-through Ethernet cable (not supplied),
connect one end of the Ethernet cable to the LAN port of your
wired Ethernet broadband router and the other end to CI 8-120’s
LAN port.
NOTES
• NAD is not responsible for any malfunction of the CI 8-120 and/or the
internet connection due to communication errors or malfunctions
associated with your broadband internet connection or other
connected equipment. Contact your Internet Service Provider (ISP) for
assistance or the service bureau of your other equipment.
• Contact your ISP for policies, charges, content restrictions, service
limitations, bandwidth, repair and other related issues pertinent to
internet connectivity.
9 RESET
• Use the RESET button to manually restore CI 8-120 to its factory
default settings.
• While at operating mode, press and hold RESET button until
Standby LED continuously ash in amber color. Release hold of
RESET button. Factory reset is completed when the continuously
ashing amber Standby LED stops and unit goes to standby mode.
