SOURCE: we have a Marantz sr4500,

It is not so easy to probe into to find a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.In this case I think that some capacitors are faulty as when the set is put on it charges on to make the amplifier work. Possible fault in the protect circuit or preamp.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

SOURCE: how do i attatch preamp to marantz sr9200 for phono

If you are talking about a phono preamp, take the output rca cables from the turntable, "red and white" plug it into the preamp input, "labled" next take a red and white cable wire male ends, "3 to 6" feet long, and plug the one end in the output of the preamp, "labled" and finally plug the remainder into the AUX input of the Marantz receiver matching the colour codes so the left and right channels don't get mixed up, you now should be good to go.

SOURCE: Marantz NR 1403 & Preamp - Volume cannot be controlled by receiver

The newer surround sound recievers will not work no matter what you try with them the way you have it hool up, they are not design to be useing a turn table on them that has a mgnetic cartridge ,Evan if you buy a phono preamp for it, you are just wasteing your time end money, I was a electronic tech for over 40 years ,Before i retired this summer, End no lots of people who tried to do the same thing your trying to do ,End It would not work,

Connected to turn table. having sound problem. At 99, sound hardly audible.


The bose as most all in one systems do not have an inbuilt phono stage. Phono especially MM type have a very low signal and an eq curve that gets altered in the phono stage. Without a phono stage (known as a phon pre amp) you will not get much fun from your turntable. To connect : turntable out - into phono preamp - phono pre amp out into bose line in/aux in

Selecting phono preamp for Onkyo HT-R510


The magnetic cartridge preamp should work with the turntable, as presumably it will have a magnetic cartridge in it. The only reason that the amp states "magnetic" is that some very old turntables have ceramic cartridges which should not be connected to that terminal. Even if the turntable had a "ceramic" it could be replaced with a magnetic one!

There is very low sound from turntable to teac


Check out if the earth connections are are good in the jack.
Are you connecting to a dedicated socket for turntables on your amp? Turntables have to have a pre-amp stage (unlike CD/Tape) before they go to the main pre-amp. If the Teac doesn't have a turntable socket, you will need to buy a pre-amp for the turntable.

The left channel tends not to work intermittently. I have tested the pre-amp and it appears it is from the turntable. One day it might work and the next it will not.


There will be a pre-amp in the turntable too, presumable you have checked the cartridge, and the everything on the turntable for bad connections?
If yes take the base off and check the pre-amp.

Connect a phonograph turntable to a receiver w/o phono connection


you will need a little box called a pre-amp. This hooks up between the turntable and newer receivers without a phono input. A basic explaination & drawing of this type of setup can be found here
