PLEASE NOTE: When sending a 9 to 12VDC
trigger to the CT-10’S Trigger In, the front
pannel’s Standby control button will be disabled.
If the device you want to use to control your CT-
10 doesn’t have a 2.5 mm trigger output
connector, you can cut one plug off the cable
and terminate the end as needed. The tip should
be positive and the sleeve negative.
TRIGGERING OTHER COMPONENTS FROM
THE CT-10
The CT-10 12V Trigger Out jack loops through
the same +12 Volts DC voltage received at its
12V Trigger In jack. This makes it convenient to
control the power to other manufacturers
electronics equipped with similar 12 Volt control
systems. For this purpose, you will need to
acquire the following accessories:
• A second trigger cable with 2.5 mm sub-mini
plugs.
• A component that can be triggered with an
external +9 Volts DC to +12 Volts DC trigger
voltage.
Before Connecting, make sure to remove power
to all the components in your audio system.
Connect one end of this cable to the 12V Trigger
Out jack on the CT-10 and connect the other end
to the component you want to trigger.
PLEASE NOTE: If the device you want to control
with your CT-10 doesn’t have a 2.5 mm trigger
output connector, you can cut one plug off the
cable and terminate the end as needed. The tip
should be positive and the sleeve negative.
PLEASE NOTE: The information found in this
section is pertinent to custom installation and
trades people only. Please disregard this
information if you are not one of the
aforementioned.
RS-232 CONTROL
The CT-10’s RS-232 connector is used only if you
have a computer-based system controller. The
CT-10 is compatible with most system controllers.
CONNECTING A CONTROLLER TO THE RS-232
PORT
For this purpose, you will need the following
accessories:
• A computer-based control system with
RS-232 serial output.
• An RS-232 serial cable with a DB9 connector.
The pin configuration is: Pin 2 transmit, pin 3
receive and pin 5 ground.
Before Connecting, remove power to all the
components in your audio system.
To Connect:
• Plug the RS-232 cable into the RS-232 output
of the computer-based control system.
• Plug the RS-232 cable into the RS-232
connector on the CT-10.
PLEASE NOTE: If your system controller doesn’t
use a DB9 connector, the pin configuration of its
connector must correspond to: Pin 2 transmit,
Pin 3 receive, Pin 5 ground.
REGION SELECT SWITCH
The Region switch found on the rear panel
selects operation for either N. America (US) or
most European countries (EU). It changes tuning
increments and the FM de-emphasis curve for
correct frequency response. For Asia, please
consult your local Classé Dealer.
PLEASE NOTE: After moving the region switch,
you must press the ‘reset switch’ to have this
function enabled.
MEMORY BANK
The CT-10 memory bank requires some electrical
current to maintain its preset settings.
Therefore, the CT-10 should be plugged into an
AC outlet that is not switched off when the
system is turned off. Its memory will remain for
about one week without AC power so presets
aren’t lost during brief power outages that might
result from weather conditions.
RESET SWITCH
This function will erase all stations AM/FM stored
in memory and reset all of the CT-10’s functions.
The reset switch is located behind a small hole in
the rear panel to the left of the RS-232
connector. It is recessed behind the panel to
prevent accidental operation, so you’ll need a
toothpick or other non-metal tool to insert into
the hole. Push gently to avoid damaging the
switch. After pressing reset, the front panel
display will show RESET, the programmed preset
memory will be erased, all FM presets will revert
to 108, and all AM presets will revert to 1720.
OPERATING THE CT-10
STANDBY/ON AND OFF
You can turn the CT-10 on and off with the
Standby button on its front panel, with the STBY
and ON buttons on its remote control handset,
or with an external DC source. For the standby
function to work, you should have previously
turned on the power switch at the back of the
CT-10. See figure 1.
STANDBY/OFF: Press the Standby Button on the
front panel, the ON button on the remote
control, or apply an external DC voltage.
STANDBY/ON: Press the Standby Button on the
front panel, the STBY button on the remote
control, or remove the external DC voltage.
REMOTE CONTROL AND FRONT PANEL
OPERATION
Front panel and remote control operation of the
CT-10 are very similar. However, the remote
control handset gives you control of the
following functions not available on the front
panel (see figure 2):
• Standby
•On
• Discrete Preset Station Access
• Direct Frequency Entry
• RDS (Radio Data System) Activation
The remote uses two standard AAA batteries that
are included. Make sure you insert the batteries
in the direction indicated on the molded battery
compartment. Please recycle and replace them
only with alkaline batteries.
SELECTING RADIO STATIONS
FM & AM BANDS
The FM-AM button on the front panel and
remote control switches between FM or AM
bands. Each time you press the FM-AM button it
toggles between FM and AM.
PLEASE NOTE: The CT-10 remembers if you were
listening to an FM or AM station before you last
turned it off. You don’t need to press the FM-AM
button if you want to continue listening to the
same band.
There are several ways to select a station on your
CT-10. Each method is described in detail below:
• Tune to the previous or the next available
station
• Tune to the previous or the next frequency
• Select an individual preset station
• Directly select the station frequency
• Select the previous or the next preset station
SELECTING STATIONS – SEEK TUNING
This tunes or seeks only those stations that the
CT-10 can receive clearly. Seek tuning doesn’t
stop at weak stations where there’s too much
background noise.
SEEK TUNING WITH REMOTE CONTROL
• Turn on the CT-10 by pressing the ON button
on its remote control or the Standby button
on its front panel. The station you had
previously selected will appear in the display.
• Press the AUTO button on the remote
control. < SEEK > will appear in the display.
• Press the /\ button on the remote control to
seek the next station.
• Press the \/ button on the remote control to
seek the previous station.
SEEK TUNING AT THE FRONT PANEL
• Turn on the CT-10 by pressing the Standby
button on the Front Panel or the ON button
on its remote control. The station you had
previously selected will appear in the display.
• Press the < TUNE/PRESET > button on the
front panel until < SEEK > appears in the
display.
• Turn the tuning knob slightly clockwise to
seek the next station.
• Turn the knob slightly counter-clockwise to
seek the previous station.
MANUAL TUNING
This permits the tuning of signals across the
entire FM and AM bands, regardless of the
stations signal strength.
