1 GLOBAL INPUT/OUTPUT
• Always turn OFF the CI 980 and other components in the system
before connecting or disconnecting anything to GLOBAL’s INPUT/
OUTPUT terminals.
• Connect the output from a pre-amplier or processor, such as a
surround-sound decoder, to the INPUT terminals. Use a twin RCA-
to-RCA lead to connect the left and right “Audio Output” of the
preamplier or processor to these INPUT terminals.
• The OUTPUT terminal is a line level “loop through”output. The
same level of input signal at the INPUT terminals is available at the
OUTPUT terminals thereby allowing the same signal to be shared or
passed on to another amplier.
• These INPUT/OUTPUT terminals are dedicated only to GLOBAL
settings.
• If the LOCAL/GLOBAL mode selector switch of a particular ZONE is
set to GLOBAL, the source connected to GLOBAL’s INPUT terminals
will become the active input for the particular ZONE.
2 GLOBAL GAIN CONTROL
• Before switching ON the CI 980 from standby mode for the rst
time, make sure all GAIN controls are set to minimum (MIN) level
position.
• This GAIN control is dedicated only to GLOBAL settings. Rotate
clockwise or counterclockwise to adjust the level of the input signal
being fed to GLOBAL’s INPUT terminal.
• Refer also to item about GAIN CONTROL (ZONE 1- 4).
3 STEREO/BRIDGE MODE SELECTOR SWITCH (ZONE 1- 4)
• Depending upon the corresponding speaker setup connection,
slide the particular Zone’s selector switch to either STEREO or
BRIDGE mode.
LOCAL/GLOBAL MODE SELECTOR SWITCH
• Slide particular Zone’s selector switch to either LOCAL or GLOBAL
depending upon the selected input. If GLOBAL is selected, the source
connected to GLOBAL’s INPUT terminals will become the active input
for the particular ZONE. On the other hand, if LOCAL is selected, the
active source at corresponding Zone’s INPUT terminals will be applied.
To illustrate, if LOCAL/GLOBAL mode selector switch of ZONE 4 is set
to GLOBAL, the input from GLOBAL’s INPUT terminals will be the active
input for ZONE 4. On the other hand, if LOCAL/GLOBAL mode selector
switch of ZONE 4 is set to LOCAL, input from ZONE 4 INPUT terminals
will be the active input for ZONE 4.
4 SPEAKER OUT (ZONE 1 - 4)
• Connect the speaker cables to the supplied speaker connector with
reference to the particular Zone’s SPEAKER OUT terminal markings in
the rear panel.
• At STEREO mode, ensure that particular Zone’s “R+” is connected
to the “+”terminal of your right speaker and “R-” connected to the
speaker’s “-”terminal. Connect the particular Zone’s SPEAKER OUT
terminals marked “L+” and “L-” to the left speaker in the same way.

BRIDGE MODE
A particular ZONE can be congured to be MONO (Bridge mode), more
than doubling its output power. This way, a particular ZONE can be used
as part of a high power stereo or home-theatre system by connecting
additional power ampliers. In this mode, the amplier section will
react as though the speaker impedance has been halved.
At Bridged mode, ZONE 2 will produce approximately 100W into an
8 ohm loudspeaker. Low impedance speakers (under 8 ohms) are
not recommended when using Bridge mode as these may cause the
amplier’s thermal cut-out to operate if played at high levels.

5 INPUT/OUTPUT (ZONE 1 - 4)
• These INPUT/OUTPUT terminals are dedicated to their respective
ZONE SPEAKERS.
• Always turn OFF the CI 980 and other components in the system before
connecting or disconnecting anything to the INPUT/OUTPUT terminals.
• Connect the output from a pre-amplier or processor, such as a
surround-sound decoder, to corresponding Zone’s INPUT terminals.
Use a twin RCA-to-RCA lead to connect the left and right “Audio
Output” of the preamplier or processor to these INPUT terminals.
• A Zone’s OUTPUT terminal is a line level “loop through”output. The
same level of input signal at the INPUT terminals of a particular
Zone is available at the corresponding OUTPUT terminals thereby
allowing the same signal to be shared or passed on to another
amplier.
6 GAIN CONTROL (ZONE 1-4)
• The CI 980 is equipped with separate GAIN controls for each Zone.
• Before switching ON the CI 980 from standby mode for the rst time,
make sure all GAIN controls are set to minimum (MIN) level position.
• Rotate clockwise or counterclockwise a Zone’s GAIN control to
adjust the level of the input signal being fed to the corresponding
INPUT terminal.
Level Matching
In a surround sound or system with more than one set of speakers,
dierences in levels can occur due to varying ineciencies among the
speakers. In case your preamplier or processor also has individual trims
for each channel, set these to neutral or mid position (usually marked as
0dB). Adjust the GAIN control so that the speakers driven by the CI 980
have the correct level compared to the other speakers, judging from
your listening position.
Extended Volume Control Range
Many systems have so much voltage gain that the speakers (or your
ears) are overdriven at any volume control setting higher than 11 or 12
o’clock. As a result you are conned to using only the lower half of the
volume control’s range, where adjustments are imprecise and where
channel balance errors tend to be greater.
If the input level is reduced, you can turn up the volume control of
your processor or preamplier, making more eective use of its range.
(Suggestion: adjust the GAIN controls so that your preferred maximum
sound levels usually occur at about 2 or 3 o’clock on the volume
control.) As an added benet, this procedure suppresses any noise
produced by the preamplier’s high level circuitry (e.g. any residual hum
or hiss that does not go away when the Volume is turned down).
7 AC MAINS INPUT
• The CI 980 comes supplied with a separate AC Mains cable.
• Before connecting the plug to the mains power source, ensure that
it is rmly connected to the CI 980’s AC Mains input socket rst.
• Always disconnect the mains power plug from the mains power
source rst, before disconnecting the cable from the CI 980’s AC
Mains input socket.
8 FUSE HOLDER
• In the unlikely event a fuse may need to be replaced, unplug the AC
cord from the wall. Then, remove all connections from the amplier.
Use a athead screw or similar to open the fuse holder via the slot
located on the top edge of the fuse holder. With the screw driver in
place, push it outward to unlatch and open the fuse holder. Only
replace the fuse with the same type, size, and specication.
• Only replace the fuse with the same type, size, and specication -
T6.3AL 250V.
IMPORTANT NOTICE
Do not use any substitute fuses of dierent types or with dierent ratings
or values. Failure to observe this precaution may cause damage to the
amplier circuits and may create a re hazard and/or defeat the safety
built into the amplier and may void the warranty.
9 +12V TRIGGER IN/OUT
• The +12V TRIGGER IN allows the CI 980 to be remotely switched
from standby mode to operating mode and vice-versa by ancillary
equipment such as a preamplier, AV processor, etc. The controlling
device must be equipped with a 12V trigger output to use this
feature.
• The +12V TRIGGER OUT is used for controlling external equipment
that is equipped with a +12V trigger input. With TRIGGER - OFF/
ON/AUTO set to OFF, this output will be 12V when the CI 980 is at
operating mode and 0V when it is at standby mode or powered
OFF.
• Refer also to the item about“TRIGGER IN/INPUT SENSE - OFF/ON/
A U TO ”.
10 TRIGGER - OFF/ON/AUTO
• This switch has three settings - OFF, ON or AUTO.
• At OFF setting, +12V TRIGGER OUT will output 12V when CI 980 is
at operating mode and 0V when it is at standby mode or powered
OFF.
• At ON setting and with the +12V TRIGGER IN of the CI 980
connected to the DC output jack of a compatible auxiliary
component, the CI 980 can be switched remotely from standby
mode to operating mode and vice-versa. Use a 3.5mm mini-jack to
pass +12V from the auxiliary equipment into the CI 980.
• At AUTO setting, the CI 980 will instantaneously turn to
operating mode from standby mode if it senses any input signal
(approximately above 20mV RMS input) applied through any of the
GLOBAL or ZONE INPUT sockets.
• Slide the OFF/ON/AUTO switch to OFF setting for the CI 980 to be
normally switched ON (or back to standby mode) using the front
panel STANDBY button.
NOTES
• With the rear panel POWER switch at ON position and the OFF/ON/
