DJ turntable issues?

I have purchased a Pioneer PLx500 just want to play some records, but no sound is coming out of the speakers, I have fixed the anti skate to what seems to be correct, now the needle just stays in position as the record spins, if I change tempo I hear minor sounds but no music, I’m a completely newbie with turn table any advice would be appreciated thanks

    Find a local audio nut with turntable experience for in-person assistance.

    Could be a turntable cartridge malfunction. If you position your ear close to the needle or stylus you should hear the music at a very low level. If you do not hear any music then it is a cartridge problem (the stylus is part of the cartridge). If you hear the music at the stylus but not from the speakers, then there may be a problem with a loose cable, the amplifier's circuitry that processes the phono input or some wire that is broken or loose between the cartridge and the turntable.Even if the needle does not move laterally as it plays (e.g. because of a broken LP record), you should hear the same musical passage playing nonstop.  BTW, that is where the phrase broken record came from.

    What have you got it connected to?

    It must connect to an audio power amplifier of some sort.

    If you have amplified speakers, switch it to "line" level output and you should be able to connect it directly to them using the RCA connections or adapters from those.

    Likewise for an amplifier aux input, use line level mode.

    The "Phono" mode disables the internal preamplifier so it can connect to amplifier with a built-in dedicated low-level phono input, or a separate phono preamp unit.

    The USB socket is only for connection to a computer for recording from the turntable etc., it cannot connect to speakers.

    ps. It may have been supplied with a protective cap over the cartridge/stylus tip - have you removed that, if there was one?

    It should look like this:

    The biggest issue here is that you say “the needle just stays in position as the record spins”. Do you mean that it just stays where you put it and doesn't move towards the centre of the record as it plays? If so, then it suggests that the stylus (needle) isn't in contact with the record. In a quiet environment if you put your ear close to the platter as it revolves you should be able to hear the mechanical sound of the record being played.

    Otherwise, you don't say what you have connected the turntable to. Connecting it to standard speakers will not produce any sound. You need either active (or “powered”) speakers or an amplifier. If you are connecting directly to a power amplifier or active speakers the switch on the back needs to be set to “line”. Make sure you start with the volume control on whatever to plug into low.

    Good luck.

    Added, I guess that you've just abandoned your question but it would be really nice if you responded to the people trying to help and explained - is the record actually playing (in which case the problem is electrical) or not (in which case the fault is mechanical)

    To answer that without making the following educated guesses, you need to explain exactly how you have connected it to your speakers.

    The PLX-500 has a switchable phono/line output. That means it does not require a preamplifier, nor does it require an “integrated” amplifier (amp with a built-in pre-amp). But it does still need a power amplifier.

    So if you have that switch set to “phono” as all but the most audiophile users will, then you can connect it to either the phono input of any power amplifier, or you can connect it directly to powered speakers which contain their own basic power amplifier. 

    If that switch is set to line output then the only power coming out is the tiny few milliamps generated by the movement of the stylus, and that won’t even register on a normal power amplifier or on powered speakers. That output is intended to be run via a pre-amplifier which boosts that signal up to phono output levels, and that phono output then gets fed into a power-amp (Or to powered speakers), or is done internally if using an integrated amplifier. 

    A separate pre-amplifier can easily cost as much as a good power-amplifier, and is intended to produce a better, cleaner, output than the pre-amp built in to your turntable or one built in to an integrated amp, both of which are normally built to do the job adequately at lowest cost.

    The other obvious thing to check is that if the switch has been set to phono, that you haven’t made a common silly error and connected the other end of the cable to outputs on your amplifier. It will also be worth positively clicking that line/phono switch back and forth a couple of times to ensure it has fully engaged into the chosen position. But if you have to do that all the tine then the switch is faulty and the turntable should be returned under warranty for a complete exchange as accepting a repair could leave you without your new toy for weeks for what is a very simple repair.

      Robert J: Yes, thanks for pointing that out. It shows the perils of posting in a hurry whilst commuting and still half-asleep.
