Built in Pre-Amp has gone out

I recently found out that you can actually turn OFF the built in pre-amp and think that perhaps someone in the household did so accidentally.
Can anyone let me know where the control switch is or any other ways to troubleshoot a problematic pre-amp?

    I found the switch after the fact.
    But the pre amp was on and the player still isn't playing properly.



1 Answer

Remove the turntable pad (part where the record sits) and the switch is in the corner.

Volume from turntable too low

Have you got it connected to a dedicated "phono" sockets that has an in-built pre-amp for it?
If you haven't got one you might need a magnetic cartridge pre-amp.
If it has got a pre-amp then it's possible the pre-amp has failed. To check, remove the wires from the cartridge. And with your finger (with the unit connected to an amp and it switched on) touch the wires one at a time. You should hear a loud buzz on two of the wires. If you do the cartridge is faulty. If you don't the pre-amp has gone. The pre-amp failure will not effect any other function on the amp. Pre-amp's are these days a single IC, which will need to be replaced.

My record players sound quality is really low and idk what the problem is. The vinyls aren't dusty and it used to be so much louder so can you please help?

Unless you are connecting to a different amplifier and the sound is low on that, the likely cause is the pre-amp of the amplifier. Since the record deck uses a separate pre-amp on your amp it won't affect the other functions. You can confirm that it's gone by removing the wires from the cartridge. With the amp on and deck still connected touch the wires with your finger. If there is only a small buzz from two of the wires, this will confirm the pre-amp is the problem. However if you hear a loud buzz from them, the cartridge is faulty.
If you have knowledge of electronics you can trace the pre-amp inside the amp. It's probably a small IC that has gone, which if you can get the replacement part should cure the problem.
If you are connecting the deck to another amp, then that amp might not have a Magnetic Cartridge Pre-amp built in, but you can buy these separately.

Using turntable (audio technica at-lp 120) with built in pre amp the sound is distorted and broken up. the turntable requests phono turned on to use. Does the receiver have a pre amp or boost signal...

A turn table produces sound voltage in the millivolt range. If you have it connected to a receiver that has a phono input and the turn table is pre-amplified, you are overdriving the receiver and it is clipping the audio and making it sound bad.

How to connect sony dav-hdx 900 to turntable

If the Sony has a dedicated "phono" or record deck socket, you should use that. Many modern amps however don't. In which case use a tape in socket or aux one. You will also need in-between the two devices a Magnetic Cartridge Pre-amp. These can be found by searching the internet. Without this device the sound will be very low. Amps with dedicated sockets normally have the pre-amp built in. Consult your user manual to see if it does have one built in.

Do I need a pre-amp?

Hi, no built in pre amp. If you are connecting to an amp without dedicated phono input you will need to use a preamp or mixer. Cheers John.

Very low sound after new needle installed

Firstly the cartridge could be faulty or incorectly wired. I think what you are refering to is a magnetic cartridge pre-amp. If the turnatable has seperate audio connectors these should be plugged into the "phono" socket. And not an "aux" or "CD" input. If there is no phono socket, you wouldn't be able to plug a pre-amp in anyway. Yes the deck if it is built in should have this pre-amp built in. However these pre-amp can fail!
To test if the pre-amp is working, even if has no phono socket, unclip the leads to the cartridge. With your amp on, touch the end of each wire with your finger. On two you should hear a buzz - one for each channel. If it's not loud then there's a problem with the pre-amp. If you do get a decent buzz the cartridge is faulty.
You can also trace the wiring to the pre-amp inside the unit, if you wish to fix it. It will almost certainly end up at an IC, which should be replaced.

Ihve just purchased Kenwod P-110 turntable for my husband - do I need to purchase speakers also or can this be conected to TV Audio ???

Generally most turntables require a "magnetic cartridge pre-amp" before it becomes as loud as say a CD player. TV's generally again don't have pre-amps of this type built in. So unless the turntable has a pre-amp built in then any sound would be too low. Some amps don't have one built in so you need to check that too before purchasing any amp. You can buy the pre-amp seperatly too!

Has a muffled sound

How are you using the mic ie how far,through what type of equipment etc.. Shure make and have made great mics for years with the 58 and 57 dynamic models[very common used live and in the studio] being able to produce good clear vocal and guitar,sax etc recordings.. If you are using one of these or similar dynamic mics,then because they are not' too sensitive' ie pick up room sound/character you ought to get clear usable results from a few cm ..{a pop shield can help one move closer without pops[ppwwwooow type sound from breath].. But the pre amp level has to be set right so the sound is not to quiet but not overloading etc..{ i don't know what you have or why,so am suggesting basics} If there is a simple 2 or 3 knob eq on a mixer/amp or software,then add s little treble and less bass... If you have a good functioning set up and feel the sound lacks a certain amount of detail and you have tried all the above ,perhaps you need to consider trying out different types of mics..Large diaphram condensers perhaps..?? How about one with built in pre amp and USB input so that you can plug direct into the computer with minimum fuss ,if thats what you are using..[Rode and SE electronics make great USB mics at fair prices..] The pre amp that amplifies the signal is an important part of the chain if not using USB models ,but even a small mackie mixer with its pre amps built inwill turn out good results with some effort and experimentation.. ..Good luck..

Lack of signal to amp on turntable

You need to get a pre amp for your turntable. The 5740 does not have one built in. Not to worry, they are actually inexpensive! Google pre amp or turntable pre amp & you will find lots of good units that will do the trick for 25-45. They also give you an input ground to get rid of that lovely turntable humm. Hope this helps
