Question about Stanton STR8-150 Turntable

1 Answer

Humming noise/ feedback

Everything is connected correctly ie. amp, mixer, decks. However, when playing records there is a humming noise and feedback from the amp/ decks.
i think this has something to do with the lack of grounding for the decks.
How can i solve this problem?

Your mixer should be grounded by the power cord, and the decks have a seperate ground wire which connects, usually on a screw terminal, to the mixer, which provides the ground for the decks. I would try the headshells to make sure they are tight and connected correctly also make sure the power socket on the wall is earthed properly.

    On the STR8-150s there is no seperate grounding cable, as the decks have been redesigned from the ground up not to need this antiquated piece of hardware. There is a ground lift switch beside the power button on the underside that selects whether ground lift is present or not, depending on your power set up. If you have clean power with a good ground (3 pin style socket), make sure this is in the on position. Next, make sure that as much as possible your rca cables do not run parallel to the power cord from any device. This can cause ground hum on any set up, even one where you have a seperate groud lift cable. Consider buying some premium RCA cables with good shielding, and checking your power supply.

    Also, if you are willing to use the line output level instead of phono, you can likely get rid of this hum altogether as line impedance levels are not as subject to ground loop hum as old style phono impedance.

    The issue is not with the turntable per sey, it is in the wiring. That;'s the source of ground hum.

    If you have really, really dirty power, some success can be had by independently grounding the tone arm, but that's a stopgap solution. Really, you should probably invest in a cheap UPS to protect your gear from power spikes and dirty power.

Stanton str-150 - poor sound from left deck


Just make sure all your connections are clean , your tt in horizontal and take a new record, set the azimututh/anti-skate right , use the channel of the deck which works correct if it doesn't you have to measure the voltage coming from the cable, since i don't believe it's the mixer. But pls describe a poor sound, that doesn't say a lot. My tables often make a poor crappy sound , with channels falling out, but that's due to dust on the vinyl and stylus(needle) or a poor connection with my sme connector and then i clean both. Does is crackle and move the rca cable when you're playing, often is that stuck , but if it's on both channels , which sometimes is hard to hear in a little room. It can't be the mixer, cause i told you to test it on the other, good soudinding mixer input. So then it can be your groundwire, There ain't much more. Good tonar, clean sme connector, clean record(take the needle from the right working table). Check if the pins in the sme connector move smoothly.
Goodluck

My technics 1200 hums when connected to the amp even when the power cord is disconnected.


Is the ground wire from the deck connected to the mixer?.

If everything is connected ok then the ground wire or phono cord could be faulty - look here for replacements :-

Could also be a "ground loop" - try a ground loop isolator.

Deck fades out when i bring the second deck in (records I mean)


are you running phono pre amps ? are you running pre amps to each deck or one for both decks , if you are running pre amps maybe the power supply is not sufficient to run two decks anymore [ possibly damaged ] but it sounds like a power delivery failure to me . hope this helps

Could be a bad patch cord, a setting on the mixer, a faulty mixer (unless it works ok with other amps), or a dirty control on the Sony amp if it has analog controls. Have you tried connecting other sources to the Sony?

Technics 1210 feedback/grounding problem


Since you've already replaced your RCA cables, and tried different cartridges, the only other thing that would cause this type of issue is your tonearm. It's probably on it's way out, and will need to be replaced shortly.

You can obtain a replacement tonearm HERE, however, it's rather difficult to replace the tonearm without experience or knowledge on soldering.

Good luck!

Have a B&O RX-2 with mcc4 and loud hum


Possibly check the wires on the cartridge, make sure none of them are touching and are not bent to badly, are all the connections tight? some cartridges require plastic sleeves over the connections, this insure they don't touch and
avoids resistances between them. Also some cartridges are not compatible with certain model turn tables.Is it universal? Also you my need a mixer most turntables don't work with amps alone. Mine don't. Usually most models you attach the ground wire to the mixer. A mixer boosts table power and take stress off the amp. Hope this helped! good luck!
