Question about Marantz Audio Players & Recorders
I recently hooked up a Audiophile TC-750LC phono preamp to my Marantz NR1403 receiver. I plugged it into the pre out ports and played a vinyl. The sound only comes out of the speakers and the subwoofer does not kick on. I am also unable to control the volume through the receiver - I'm forced to use the volume control on the preamp. Any thoughts?
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,

If all the amps are going into protection mode, then the preamp may be pushing a DC component with the signal. This is a little serious,and should be investigated further. There may be some deterioration in the electronics of the preamp causing this. I would suspect a leaky transistor or bypass/coupling capacitor in the DC coupled output stages. should not be too hard fix for a good HiFi tech.

Sorry for the delay in getting back to you, you have an odd problem happening there, the pre-amp being the common denominator to the syptoms. Perhaps you could try reducing the attenuators to say 60% and retry at the same levels you used to use at the preamp. It is unlikely that there is a fault occurring that would increase the output of the preamp, more likely to be a DC component getting through. It could also be possible that the amps if all the same make and model have through over the period of installation developed the same fault.
There will have to be a common contributor to the symptoms. It is not uncommon for the same problem to affect a particular model at the same point of its life. Best approach and easiest to fault find it would be to change out the preamp with something similer to test the system and see what happens. At least tyouy will know where to start looking. Hope I have been able to help you, still happy to discuss it further. In the Free section our only reward is a FixYa ratings. Cheers

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!

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.

Some of the newer turntables come with selectable internal preamplification to solve the lack of it in modern equipment.
Volume is always handled at the electronics.
