Frequently Asked Questions - TC400Q HARMAN KARDON
How do I connect my speakers to the Harman Kardon TC400Q?
Use speaker cables with bare wire or banana plugs. Connect to the Speaker A or B terminals on the back panel, matching polarity (+ to +, - to -). Ensure speaker impedance is between 4 and 16 ohms.
Can I use the receiver with a turntable?
Yes, the TC400Q has a dedicated Phono input compatible with moving magnet (MM) cartridges. Connect your turntable's ground wire to the GND terminal to minimize hum.
Why is there no sound from the speakers?
Check if the receiver is in Speaker ON mode (button on front panel). Ensure the input source is selected correctly and volume is turned up. Also verify speaker connections and that the speakers are not damaged.
How do I set the FM radio presets?
Tune to the desired station manually or via scan. Press and hold the Memory button on the front panel until the preset number flashes. Use the tuning knob to select a preset number (1-30) and press Memory again to save.
What type of remote control does the TC400Q use?
The receiver comes with a basic infrared remote that controls power, volume, input selection, and mute. It requires two AAA batteries (not included).
How can I improve FM reception?
Use the FM dipole antenna included with the receiver. For best results, extend it fully and place it in a window or high location. Avoid metallic obstacles. You can also connect an outdoor FM antenna to the 75 ohm terminal.
What is the power consumption in standby mode?
The TC400Q consumes approximately 30 watts in standby mode. For energy saving, it is recommended to turn off the unit completely when not in use for extended periods.
Can I connect a subwoofer to this receiver?
Yes, there is a subwoofer output (RCA) on the back panel. Connect an active subwoofer using a shielded RCA cable. The output signal is full-range; use the subwoofer's low-pass filter.
How do I clean the receiver's faceplate?
Turn off and unplug the receiver. Gently wipe the faceplate with a soft, lint-free cloth slightly dampened with water. Do not use alcohol, ammonia, or abrasive cleaners. Dry immediately.
Is there a protection mode? What triggers it?
Yes, the receiver has overload protection. It may shut off if a short circuit occurs at the speaker terminals, if the receiver overheats, or if the power supply is unstable. Solutions include checking speaker wires, ensuring ventilation, or plugging into a different outlet.
