Question about Denon AVR-2803 Receiver

Receiver shut down only when using phono preamp

I recently added a Music Hall mmf-5 turntable to my system with a Dynavector MC cartridge DV-10X5. I also added a Antique Sound Lab Phono LUX DT phono stage. I am connecting it to a Denon 2803 AVR using the VCR2 input. After playing the phono at high volume for a relative brief period of time(4-5 songs), the "protection circuit" trips and the unit shuts down. The unit is hot at the time it shuts down, but does not shut down with any other inputs(ie CD, DVD, DVD audio and SACD) at even higher volumes. I have tried the TV input on the receiver, changed out the RCA connections and tried another Phono LUX DT phono stage. All with the same result; the unit shuts down. I had the phono stage bench tested and installed in another system with no problems detected. I added a second ground from the phono stage directly to the ground on the turntable with no success. I put a large floor standing fan to move the air around the unit and it did not help. The Denon receiver is in a cabinet with 5 1/2" clearance on top and 3" on each side. I do not believe I have a problem with the receiver, because it works with all of the other inputs at high volumn. If anyone has any suggestions I would be most grateful.

Re: Receiver shut down only when using phono preamp

I believe you have no fault, all manufacturers employ a number of "anti-condensation" techniques (to stop moisture buildup around the door seals, some use a thermal wire (just like what's in an electric blanket, others and more exotic use hot return gas from the compressor through pipes around the door / s these get really hot but it's a really effective way to keep moisture away. Hope this helps you and others

Re: Receiver shut down only when using phono preamp

Since the protection circuit trips after 4-5 songs at high volume from LPs, it may be that the infra-sonic rumble common to phonographic recordings is driving your amp stages much harder than it sounds like they are driving. You can check this with watt meters for your speaker outputs, or by filtering such extremely low frequencies on the input. If you have an equalizer--especially an old one--it may have an infrasonic filter, or just cut the very lowest frequency available on the equalizer after running your phono pre-amp into the EQ and the EQ into your VCR2 input. This setup will verify if your problem is the infrasonic rumble, but I wouldn't use it as the solution. There are very quiet infrasonic filters available that would work better for the long term. And if you just cut the lowest EQ frequency out, you'll miss some good bass.

Re: Receiver shut down only when using phono preamp

You may want to try putting an attenuater in the line with the RCA's to cut the input signal back just a little bit. So you are not driving the amp so hard with your preamp.

SOURCE: AVR 2807 shuts off at high volumes

I had the same problem. Rebooting did the trick. Reboot the unit per the instructions provided by another user on the main page. Here they are:

To reboot, turn receiver off by the small on/off button, not the big standby button. While off press the night and pure direct button at the same time and keep holding them with your right hand while pressing the small on/off button with your left. You will see your receiver menu flash. When you see it flash let go of the night and pure direct button and the receiver will reset it self to the radio station 87.50. The receiver's microprocessor has now been set back to factory.

SOURCE: No system configration display on AVR3300 since moving.

Make sure the two switches on the remote are all of the way to left most position before you try using the SYSTEM SETUP button - if the AVR is going into SETUP, the LCD display should be saying "SYSTEM SETUP". (I think that model does - most do).  also make sure that the Composite or S-Video on the TV's input 1 work from something else like a VCR, DVD player, ETC. rule out the TV and the cable first.

Where do I connect a turntable to the AVR132? Do I require a phono preamp - if so where does this connect into the receiver?

Most amps / receivers that lack an input specifically labeled "Phono" will require a preamp for the low output that originates from turntables with modern, MAGNETIC cartridges. If your cartridge is a *much* older (1960 ~1985) CERAMIC type, it will not likely need a preamp as the output is greater than a magnetic type.

You should select an unused stereo (left & right) INPUT device such as "VID2" Connect the output of the preamp to these jacks and the turntable should be connected to the preamp input as per manufacturer's instructions.

My receiver works fine when I plug my iPod into it, but when I plug my turntable in I can't get any sound. Any idea?

The phono cartridge on your turntable puts out a much lower level signal than your iPod. Back when turntables were popular, all receivers had a special phono input to take care of that. Your modern HK receiver does not have a phono input, so you need to get an external phono preamp. Plug the turntable outputs into the phono preamp inputs, then plug the phono preamp outputs into one of the audio inputs on the HK, like where you connected the iPod.

The sound is really low if i press the aux tape cd phono or vcr the sound is there but really low

Evaluate your current receiver. Take a look at the back-panel connections to make sure you don't have a phono input. In most cases, the phono input will be clearly marked. If the connections are not marked, look for a set of RCA-style inputs with a grounding screw next to them; this is a phono input. If there isn't a phono input on your receiver, see if you have an open set of RCA inputs. If they are all occupied by other equipment, you can disconnect one piece of equipment, buy an A/V switcher or get a new receiver--preferably one with a phono input.
2 Purchase a phono preamp. The voltage output of a turntable is much lower than those of other peripheral devices, including CD players, tape decks and game systems. Although the inputs look the same, connecting a turntable to a standard RCA audio input will result in very faint sound output, if you hear anything at all. The output of your turntable must be amplified to a level of about 150 millivolts (mVs) before it reaches the receiver, so a turntable "pre-amplifier" or phono preamp is necessary.
3. Purchase patch cables. You'll need a set to run from the preamp to your receiver. Measure how long your cables need to be, and purchase accordingly. Resist the temptation to "go cheap," because better-quality cables will provide better sound.
4. Connect the preamp into the system. First plug the preamp into an AC power outlet. Most models have a small AC-to-DC adapter built into the plug. Then connect the cables from the turntable to the preamp, and connect your new patch cables from the preamp to the receiver.
5. Adjust the gain of the phono preamp. Most models have a gain control for fine-tuning. Follow the instructions provided by the manufacturer and adjust your system accordingly.

How do I connect a technics turntable to an RX-V463 AV reciever? Thank you in advance

Modern AV receivers rarely contain PHONO preamps.

A traditional turntable requires a preamp inline with it to PRE amplify and frequency-balance the minute signal produced by it's cartridge. Most stereo receivers and preamps have Phono connections and internal preamplification strictly for that purpose. Yours does NOT.

A standard turntable will require you to acquire an external PHONO preamp to place between the TT and an Aux connction on the receiver.

Some of the newer turntables come with selectable internal preamplification to solve the lack of it in modern equipment. If your turntable is that type you can select its internal preamp output and run that to an AUX input.

If the receiver doesn't have a function specifically named PHONO, yes. Very few AVR's have phono preamps. They're not expensive. I'd check eBay.

I have minimal volume coming from the turntable

You may need a phono preamp to increase your input voltage coming from the turntable. More information from you would be helpful like what kind of turntable are you using. Whate is your receiver/amp are you plugging into a phone input or a line input? Here's the science part: Typically a line level input is expecting a 2V signal. A Moving Magnet (MM) phono input would expect something in the mV range (e.g. 2 - 4 mV) and a Moving Coil input would expect 1/10th that of the MM input (so 0.2 - 0.4mV or thereabouts). If your receiver has a phonostage then you may have a different problem but this sounds like the phono is not putting out a voltage that the receiver/amp is able to amplify. Search for phono preamps (some are very inexpensive) but find out what type of cartrige your record player uses (MM,MC or crystal) all types have large differences in output signal voltage. Good-luck.

Phono input

If you mean Moving Magnet vs Moving Coil, they are different.

MM is the higher output of the two types so most Phono Preamps can deal with them.

Not knowing the specific receiver model, a direct answer to your second query is not possible. I would guess - YES.

"Since the coils are much smaller than those in the MM cartridge, the MC cartridge generates a much smaller signal."

see this great article where that originates...

You have a VERY nice turntable! TWO quick questions: 1) How do you define "minimal" volume? It is not NECESSARILY unusual that your turntable / receiver combination will have lower volume than your tuner, CD or DVD player. What happens when you CRANK IT UP?! Don't worry about the position of the volume control! 2)Are you changing the turntables output settings via the switch under the platter? Please post a reply and we'll go to the next step! Note: Ceramic cartridges are pretty much extinct. They were strictly low-end, low-cost, low-fidelity devices used in cheap audio systems of "yesteryear". Have you ever seen a BSR or Garrard turntable? Or your grandad's Magnavox Console Stereo? THAT'S where you'd find a ceramic cartridge!
