Question about Audio Players & Recorders

2 Answers

I have a Harman Kardon 700 Series amp/pre-amp/tuner system that I want to get repaired ( an HK 770 Twin Torroidal Ultra Wideband DC Amplifier, a matching HK 725 Pre-Amplifier, and a matching HK 710 Tuner) Can I still access parts to repair this system? I tried to order a power swith assembly ( for my HK 710 Tuner) from Harman Kardon via their parts dept., but was told by a Jamie there that this part is no longer available. This is frustrating, as this unit was a great one when it was in working order. There has to be a way to still access parts for this system. Thanks, Randy Wilson Ewing, New jersey

This will take a little homework on your part, but parts for this might be available. I don't kow your model well enough to know whether or not the power switch is generically available. Any possibility you can post a picture? Manufacturers are only required to maintain spare parts for 5-7 years after they stop selling that model. If the part is generic enough, other distributors will carry replacements. If all you need is the power switch, you stand a good chance that a replacemetn is available.
Keep me posted,
Dan

How can I connect a Thorens 145 turntable to it?


Your Harman Kardon AVR 85 doesn't have "phono" inputs. That means that you can not connect a turntable to it directly. You will need a "phono preamp" to amplify the very tiny signal from the phono cart enough for the HK receiver to play it. Something like this:

PYLE PRO PP444 Ultra Compact Phono Turntable Preamp

will do it. There are certainly better ones, like:

Best way to hook up Bose 901 series VI to a Harman Kardon HK3490


According to the HK site, "Stereo pre-amp outputs let you connect the receiver to an external power amplifier." So it's easy. Connect the Bose equalizer in the pre-out / amp in loop.

I have a Harman Kardon HK990 which throws an error #005 if I switch it on with a digital input connected. If digital input is not connected, it turns on without any error and all buttons work as expec


If you had a bad amplifier, as suggested, the unit would most likely have a condition known as DC Offset. In this case, the amp would immediately shut off. As you said, the amp stays on, but you have no sound. First thing I suggest, turn the unit off. Listen carefully to the top of the amp. When you first push the power button, you should immediately hear one click, followed by a second click, within 5-20 seconds. If you hear that second click, you amp is likely not bad. If you don't, then you do most likely have a blown amp, with engages the DC Protection circuit to the microprocessor(computer within your unit).

Next step is to open your owner's manual. In there, you will find a procedure called, "Return to factory reset, or default". Follow that procedure, to reset the unit back to the factory settings. Those inputs are assignable, meaning that you can make certain inputs, analog or digital. You may have set one wrong by mistake. The reset will fix that. If you need more assistance, or would like to inquire about a repair, please visit my website at, Audioserviceclinic.com. By the way, I worked for HK, JBL and Infinity. Thank you.

Amplifier doesnt turn on at all


The Signature line was always an HK high end line. If it won't turn on at all, there may be a power supply issue. If it turns on, but you have no sound, your amplifier may have DC Offset, meaning a damaged amplifier.
I was a Technical Support Specialist in Audio for HK, JBL and Infinity.
If you are interested in having your amplifier repaired, please look to my website at audioserviceclinic.com. Thank you.

Harmon kardon hk3270 shuts off after only being on about 10 sec


Disconnect speakers and wires. Bad wiring or defective speakers may be loading the amp down and causing the protection circuits inside to disconnect (no sound). If the HK is heating up (beyond what you perceive as normal) with no wires or speakers connected then you have a problem requiring expert repair.

Only hissing sound from 990 Vxi tuner


I remember a similar problem with these back when I repaired them. It has something to do with the I.F. section of the AM/FM tuner section and will require a HK service visit. Find a local HK dealer who's been selling them "forever" and ask if they have a bench tech who they would recommend for the repair. I just saw one of these on Ebay for $25.00 so I wouldn't spend much to have it fixed.

I own my harman kardon 620 amplifier for about 8 years. Now the sound from the speakers comes on and off intermittently. I have connected and disconnected all the cables to the speakers but it still has...


The problem is in the audio circuitry, there are bad solder joints on the board that need to be addressed, from your description it is a intermittent issue with the sound. Since this a high end unit I recommend a top audio technician to work on your amplifier, and I suggest not using the system until it is repaired because the risk to the audio output parts getting damaged is high and they are pricey.

Fiber Optic input


No gots. The 3485 is pre-digital stereo-only.

From the manual, page 19

"You may have observed that the HK 3485 is not equipped with digital audio inputs or surround sound decoding. If you prefer the complete home theater experience, you may wish to consider purchasing a fullfeatured Harman Kardon AVR Series audio/video receiver. However, we hope you will find that using a DVD player with the HK 3485 in smaller settings, such as a bedroom or den, surpasses the audio performance of most televisions, including those with onboard stereo speakers."
