ATTENTION!
Please make sure that the CI 940 is powered OFF or unplugged before making any connections. It is also advisable to power-down or unplug all associated
components while making or breaking any signal or AC power connections.
1 ZONE 2 (INPUT/OUTPUT)
· These INPUT/OUTPUT terminals are dedicated only for ZONE 2
SPEAKERS and corresponding STEREO and BRIDGE mode settings.
· Always turn OFF the CI 940 and other components in the system
before connecting or disconnecting anything to the INPUT/OUTPUT
terminals.
· Connect the output from a pre-amplier or processor, such as a
surround-sound decoder, to the INPUT terminals. Use a twin RCAto-RCA lead to connect the left and right “Audio Output” of the
preamplier 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 amplier.
2 ZONE 1 (INPUT/OUTPUT)
· Same description as item 1 above (ZONE 2 – INPUT/OUTPUT)
except that these terminals are dedicated only for ZONE 1 SPEAKERS
and corresponding STEREO and BRIDGE mode settings.
3 ZONE 2 SPEAKERS
· Connect the speaker cables to the supplied speaker connector with
reference to ZONE 2’s speaker terminal markings in the rear panel.
· In STEREO mode, ensure that ZONE 2 “R+” is connected to the “+”
terminal of your right speaker and the ZONE 2 “R-” is connected to
the speaker’s “-” terminal. Connect the ZONE 2 terminals marked “L+”

BRIDGE MODE
ZONE 2 can be congured to be MONO (Bridge mode), more than
doubling its output power. This way, ZONE 2 can be used as part of a
high power stereo or home-theatre system by connecting additional
power ampliers. In this mode, the amplier section will react as
though the speaker impedance has been halved.
In Bridged mode, ZONE 2 will produce approximately 70W into an
8ohm loudspeaker. Low impedance speakers (under 8 ohms) are
not recommended when using Bridge mode as these may cause the
amplier’s thermal cut-out to operate if played at high levels.
4 ZONE 2 SELECTOR SWITCH
· This selector switch is dedicated only to Zone 2.
· Depending upon the speaker setup connection, slide selector
switch to either STEREO or BRIDGE as applicable.
· Refer to item 3 above (ZONE 2) for corresponding speaker

· This dual function switch alternates between sensing a +12V input
as applied through the +12V TRIGGER IN jack or sensing any active
input signal applied at ZONE 1 INPUT or ZONE 2 INPUT terminals.
· At AUTO setting and with the +12V trigger input of the CI 940
connected to the DC output jack of a compatible auxiliary
component, the CI 940 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 940.
· If there is no 3.5mm mini-jack inserted at the +12V TRIGGER IN
jack and with the switch still at AUTO setting, the CI 940 will
instantaneously turn to operating mode from standby mode if it
senses any input signal (approximately above 20mV RMS input)
applied through ZONE 1 INPUT or ZONE 2 INPUT sockets.
· In the absence of a +12V trigger input or any input signal at ZONE
1 INPUT or ZONE 2 INPUT sockets and with OFF/AUTO switch set to
AUTO, the CI 940 will switch automatically to standby mode. Slide
the OFF/AUTO switch to OFF setting for the CI 940 to be normally
switched ON (or back to standby mode) using the front panel
STANDBY button.
