IDENTIFICATION OF CONTROLS
REAR PANEL
7 +12V TRIGGER IN/INPUT SENSE - OFF/AUTO
· 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.
·
Refer also to the section below about "AUTOMATED TURN-ON LOGIC
(ATO LOGIC)".
IMPORTANT NOTICE
With the rear panel POWER switch at ON position and the OFF/AUTO
switch at AUTO setting, the CI 940 cannot be switched ON using the front
panel STANDBY button. 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.
NOTES
· Switch the rear panel POWER switch to ON position in order to make
use of the +12V TRIGGER IN or INPUT SENSE AUTO feature as well as the
front panel STANDBY button.
· It will take about 10 minutes for the CI 940 to go to standby mode when
the input signal source is turned OFF.
8 +12V TRIGGER INPUT
·
The +12V TRIGGER input allows the CI 940 to be switched remotely
from standby mode to operating mode and vice-versa by ancillary
equipments such as a preamplifier, AV processor, etc. The controlling
device must be equipped with a 12V trigger output to use this
feature.
·
Refer also to the item above about "+12V TRIGGER IN/INPUT SENSE -

9 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 amplifier.
Use a flathead screw driver or similar to open the fuse holder via
the slot indicated. With the screw driver in place, push and turn
counterclockwise to open the fuse holder.
· Only replace the fuse with the same type, size, and
specification - T6.3AL 250V.
IMPORTANT NOTICE
Do not use any substitute fuses of different types or with different ratings
or values. Failure to observe this precaution may cause damage to the
amplifier circuits and may create a fire hazard and/or defeat the safety
built into the amplifier and may void the warranty.
10 AC MAINS INPUT
·
The CI 940 comes supplied with a separate AC Mains cable.
· Before connecting the plug to the mains power source, ensure that
it is firmly connected to the CI 940's AC Mains input socket first.
· Always disconnect the mains power plug from the mains power
source first, before disconnecting the cable from the CI 940's AC
Mains input socket.
11 POWER SWITCH
· The POWER switch supplies the master AC mains power for the
CI 940.
· When the POWER switch is set to ON position and with +12V
TRIGGER IN/INPUT SENSE set to OFF, the CI 940 goes to standby
mode as indicated by the amber status of the Standby LED. Press
the front panel Standby button to switch ON the CI 940 from
standby mode.
·
If you intend not to use the CI 940 for long periods of time (such as
when on vacation), switch off the POWER switch.
