Q: I need an owner's manual for my Denon product.

A: Manuals for recent products can be downloaded from Denon in PDF format. Click Here . Older manuals can be purchased from us. Please email .

Q: My Denon receiver is acting strangely.

A:  Some receivers can be affected by power fluctuactions. Many have procedure to reset to factory settings. Sometimes this will correct the problem. Generally most Denon receivers made after 1994 will have that information listed in the service manual. If yours doesn't and you would like to know how, email us . Note: the procedure will erase all user settings. Also some consumer electronics devices have trouble with energy saver lightbulbs. You might try removing the bulb to see if that is the problem.

Q: I cannot hear the subwoofer through my Denon receiver in surround modes.

A:  Most Denon receivers will not play through the subwoofer output if the front speakers are defined as 'Large'.'Large' implies that the front speakers are large enough to reproduce all of the bass. In the 'Large' mode, the subwoofer signal is mixed with the front signal instead of being sent to the Subwoofer output jack. Check the owner's manual for setup information to change the definition to 'Small'.

Q: My Denon car receiver is acting strangely. How do I reset it?

A:  You can try to initialize the receiver back to factory settings. Note this will erase all the user settings. Most Denon car receivers have a small recessed reset button about 1/16" in diameter (1.5mm) on the front panel. You may have to hunt for it. Gently press this button with ball point pen. If initialization does not help, the unit will need repair .

Q:  My Denon DCH-470 won't eject and display on the head unit reads 'RST1' or 'E-1'

A:  That error means the unit's mechanism is unable to eject the cartridge. That is not a user servicable problem and the changer will need to be repaired. Click here to find out to send the unit to be serviced.

Q:  My receiver clicks off or goes into 'Protect' mode.

A:  You may have a problem with your speakers. Try disconnecting the speaker wires from the receiver. If the receiver still goes into protection, try the reset procedure above. If that doesn't help, the receiver will need to be repaired. Click here to find out to send the unit to be serviced.
If the receiver stays on without the speakers, then you may have a problem in the wires or the speakers. Note that in rare instances, problems in the receiver will only show when actually connected to speakers. Inspect the wires to make sure the metal conductors of wires are not touching each other. See you owners manual for instruction on how to strip the insulation off. Often, we find speaker wires inproperly stripped or connected. The best bet is to try a different set of speakers on the receiver. Maybe you can borrow a small set. Your dealer may also be able to check it for you.

Q: I can't see my receiver's on-screen display on my TV/monitor.

A: Most Denon AV receivers provide the 'On Screen' display at the Monitor outputs (S-video and Composite). Be sure your television or video monitor is connected to one of these.

Q:  My speakers hum when I connect my VCR cables to my receiver

A:  If your system has cable system connected and another grounded device (satellite dish, amplifier with grounded plug, outside grounded attenna), the interaction between the two systems can cause hum. In some markets, your cable provided is required to connect their incoming cable ground to your power ground. You should contact your cable provider or an electrician if you are not sure.

Q:  I have a new phono cartridge. I have these four colored wires hanging here from my tone arm. How do I hook them up?

A:  Here's the standard phono wire assignments:

Wire Color Red Green White Blue
Connection Right + Right - Left + Left -

Q:  My system has very little bass.

A:  It's possible you speakers are wired 'out of phase'. Easy way to check: listen to the system; then reverse the wires on the black (-) and red (+) terminals on one speaker only. Then listen to the same music again. If you have more bass, then this is the proper polarity or 'phase' for you system. It's best to listen to the music right between the two speakers to determine the polaritiy. If you have even less bass, revert back to your original connections. Also note that speakers have the most bass on the floor, and closer to the walls. They generally will have the most bass (sometimes too much) when placed in corners.Speakers placed up on shelves will often have weak bass unless used with a subwoofer on the floor.
