INSPECTION AND ACCESSORIES
The Classé CT-10 has been carefully wrapped in heavy gauge plastic, packed in semi-rigid foam and contained in a special box. Inspect the unit and accessories for any concealed damage.
Report any concealed damage to your dealer promptly.
Apart from the owner's manual, please ensure the following is also included:
•Detachable A.C. power cord.
•Remote control handset (along with two (2) type “AAA” batteries).
Please report any missing parts to your dealer promptly and bring him/her (or fax him/her) the inspection report found in the box.
SETUP
The CT-10 TUNER must be operated on a horizontal platform (see specifications for details) such as a table or, preferably, specialized audio furniture to extract the best performance. Like fine turntables and interconnect cables, the final location of the CT-10 should be free of any hum- inducing magnetic fields, such as those caused by power amplifiers, AC line filters and other regulation devices. Such locations can introduce noise into an audio system, which inevitably degrades sound quality. Ideally, a few feet should separate the CT-10 from the power amplifier.
The CT-10 should not be located near a CD or DVD player since this can cause reception problems. Keep low-level interconnect cables away from the power amp and separate from A.C. power cords. The CT-10 generates negligible amounts of heat. Therefore, air space around the CT-10 for ventilation need not be a concern.
AUDIO CONNECTIONS
Connect your tuner to the pre-amplifier, using cables/interconnects in your system. For a single- ended (un-balanced) system the cables will be connected to the RCA on the rear panel of your tuner to an unused line level input on the rear of your pre-amplifier/integrated amplifier. For connection to a balanced system, the balanced cables will be connected to the XLR outputs marked “Balanced” on the rear of your tuner to the balanced inputs on the rear of your pre- amplifier or integrated amplifier. For visual aid, use figure 1.
ANTENNA CONNECTION
Connect your FM antenna cable to the ANTENNA terminal on the rear panel of the tuner. The connection type on back of your tuner is an “F” connector (75 ohms). Should your antenna cable be 300 ohm twin lead, you may convert this to 75 ohms with a 300 ohm to 75 ohm balun/ transformer.
Make sure that the center conductor of the cable is properly inserted into the connector.
PLEASE NOTE: Many countries that use 220/230 and 240 volts use FM transmitters with special tuning emphasis. Tuning de-emphasis required from the CT-10 in these countries may be different. Please consult your Classé Audio Dealer or Distributor for the correct usage. If your tuner is used in a country where the tuning de- emphasis is set incorrectly the sonic performance will be seriously affected.
You will need to connect different antennas for both FM and AM reception. Refer to the
Reception and Performance Information
section for detailed information regarding antennas.
FM ANTENNA
An FM “dipole” antenna is a pink-hued flexible wire that looks like a “T” when it’s stretched out. This is a good antenna for system setup and evaluation, however it has limitations to overall performance, and a higher quality antenna system is recommended. Please see the reception and performance information section of this manual for further details on selecting the antenna system best suited to your needs.
To connect:
•Use a screwdriver to loosen the two screw terminals on the adapter.
•Slide one of the metal spade lugs under each screw terminal.
•Tighten the screw terminals so the spade lugs are firmly secured and not touching each other.
•Slide the balun adapter onto the threaded round antenna connector on the CT-10.
•Position the antenna for best FM reception.
•Fasten the antenna on the wall or behind the equipment cabinet.
AM ANTENNA CONNECTION
For AM reception, you will need a separate molded plastic loop AM antenna with spade lugs at the end of its two wires. With this antenna, you can receive AM stations in many urban and suburban locations. Please see footnote on maximizing AM performance on this page.
To connect:
•Loosen the two AM terminals on the CT-10 rear panel. No screwdriver is needed.
•Slide the spade lug from each antenna wire under one of the AM terminals.
•Tighten these terminals so the spade lugs are firmly secured and not touching each other.
•Position the loop antenna as far away from the CT-10 as possible to minimize its interference with the AM section for best AM reception.
PLEASE NOTE: The AM antenna can be mounted to the rear chassis of the CT-10. This is done for convenience but requires careful positioning to avoid interference. If you are unable to eliminate any antenna interference, mount the AM loop antenna as far away from the tuner and any metal surface as the provided cable will permit.
USING THE CT-10 WITH INFRARED REPEATER SYSTEMS
EXTERNAL REMOTE INPUT AND LOOP OUT
The IR input allows for infrared remote control operation via a wired infrared repeater system or system controller when infrared commands cannot directly reach the front panel infrared receiver. This input connector accepts a standard 1/8-inch (3.5 mm) two conductor mono mini plug. The tip is positive and the sleeve is negative. Your Authorized local Classé Audio, Dealer or Custom Installer can recommend a compatible infrared repeater system for the CT-10. The External remote circuit has a loop output so you can connect additional IR controlled devices.
CONNECTION OF INFRARED REPEATER
The IR In jack is for a wired infrared repeater system or system controller. It eliminates the need for a stick-on front panel IR flasher. For this purpose, you will need to acquire the following accessories:
•An infrared receiving eye.
•A power supply for the IR system.
•A connecting block from the external IR system’s manufacturer.
•One cable with 1/8” mini mono plugs at both ends.
To connect:
•Plug the receiving eye into the input on the connecting block.
•Plug the power supply into the connecting block.
•Push one of the cable’s 1/8” mini-plugs into the connecting block.
•Push the other end of this cable into the IR In jack on the CT-10.
•Plug an IR flasher or other IR repeater into the CT-10’s IR Out jack to control another component if desired.
PLEASE NOTE: IR repeater connections may vary by brand. Refer to the installation manual of your IR repeater system for more information.
DC TRIGGERING
The CT-10 can be turned on or off automatically with a 12 VDC trigger from an external DC voltage source such as a preamplifier or system controller.
For this purpose, you will need to acquire the following accessories:
•A trigger cable with 2.5 mm sub-mini plugs.
•A component with an external +9VDC to +12VDC trigger voltage.
Before Connecting, make sure to turn off the power to the CT-10.
To connect, insert one end of this cable into the 12V Trigger In jack on the CT-10.
Plug the other end into the device with an external DC trigger voltage.
