AVLink Pre-amplifier For Turntables, Black

I had a stand alone turntable, which originally was part of a music centre. After the original system developed a fault, I brought a newer, second hand one, to plug the turntable into. However, the sound was very quiet, and after reading up, discovered I may need a pre amp. Not wanting to spend too much, just in case, I sent for this. Hey presto, it works a treat, with a great sound. So far, so good.

I built this preamp into an Ariston 1200 turntable plinth with a Stanton and also a Goldring cartridge. The preamp is designed to raise the few millivolts of such (hi–fi) cartridges by about 40db or 100 times to match the line input of an amplifier. It also has the necessary RIAA frequency response to compensate for such cartridges. The metal case must be earthed via the screw in order to prevent extraneous hum pick–up. If it were to be connected to the input or supply permanently there could be the possibility, in some cases, of introducing an earth loop. The preamp seems to be very low noise and hum and works very well, is small cheap and saved me the bother of making one. JPM

It was cheap and works. If I'd have given it any thought I might have gone for something a little more expensive. I wasn't 100% sure a pre-amp would solve the problem I had with a change of turntable so went for the cheapest option. It did solve the low volume issue very well. But as with many other reviews on here, there was a humming noise when switched on. Doesn't affect the sound quality when records are playing so it's not that much of a problem. So much so, I'll not bother buying another any time soon. I'm very happy with it. Mains or battery powered. I've inserted a battery now. Works great

I knew I was buying a pre-amp for my turntable, so was not surprised with this product. Small, compact and easy to use. It could use a PP3 9V battery or the mains adapter. I went for the battery (because I had one!) and because I now pre-amps are very noise sensitive. Which brings me onto my next subject - the hum and the buzz! The pre-amp box has no means of connecting a 'ground', 'earth' or '0V' connection; and sure does it need one!! I found a screw at the end I thought was for that reason, but does nothing because it screws into plastic. I tried grounding the metal case, but did naff all, so it's 'floating' (not grounded itself). If I used a ground wire to the phono 0V connection, hey presto, hum/buzz gone, but no way of making it a permanent hardwire connection. I plan to get my soldering iron out, drill a hole into the metal case and make a common ground for all. I will let you know how I get on!

great piece of kit works well

I guess you get what you paid for... But the total lack of support for grounding is astonishing, and borderline dangerous. The unit hums like a buzzsaw, and renders it almost unusable. But it's cheap... So I guess, the old rule applies here as well. YOU GET WHAT YOU PAID FOR... Anyway, if you look for a quick way to revive your old TT, just walk a few more miles and leave that unit at arm's length at all time. It's a waste of money...

I have a very good turntable purchased well over 20 years ago. Haven't used it for years and all my vinyl has been stored away. Decided to try hooking the deck to the auxiliary input of my stereo system via a pre-amp to bring the deck output to line level. To summarise; it works great and for the price I cannot fault it. It comes with a mains power unit, but the design also allows the amp to be powered by a 9 volt battery - nice feature. Need to make sure that you ground the unit via the earth connection on the deck because otherwise you will get some audio hum when there is no record being played. This will probably be the case whatever product you buy and the only downside of this great little unit is that there is no specific point of termination provided for the earth wire. I simply soldered the earth to the outer casing of the input jack and the hum was totally eliminated.

Technics turntable used but this is making a low buzz/humm in the background when used with my bose theatre system via RCA input sockets Shame, worse when at high volume

Perfecto, lo que se espera de un preamplificador para phono es que aumente los milivoltios de salida en RCA. Y eso es justo lo que hace. Dicho de otra nabera, te convierte los agudos en graves y hace el sonido perfecto. Este aparato cumple con las espectativas. Por poner un pero, que el enchufe de la fuente de alimentación no es el estandar de españa entonces con una clavija de otro aparato inservible has de pelar los cables y enroscar en los bornes de este y luego con cinta aislante dejar todo bien precintado o comprar un adaptador en un chino (1,75€).

Pessimo, inserisce un rumore di fondo non eliminabile , che si avverte non appena si alza il volume. Certo , costa poco, ma non vale di più.

Der Vorverstärker hat einen UK-Stecker - ein entsprechender Adapter liegt dem Artikel nicht bei. Ich habe den Verkäufer kontaktiert, jedoch keine Antwort bekommen; muss mich nun entscheiden, ob ich diesen Artikel zurückschicke oder einen Adapter kaufe. Artikel = Note 6, da dieser unbrauchbar ankommt, Verkäufer = Note 6, da dieser solche Artikel vertreibt und auf Anfrage nicht reagiert.

Avevo già comperato un oggetto dello stesso tipo ma era risultato inutile in quanto nemmeno amplificava, per fortuna l'ho potuto restituire senza alcun problema recuperando la somma spesa. Ho ordinato questo oggetto con un poco di diffidenza ma debbo convenire che risulta efficientissimo con una amplificazione accettabile e soprattutto priva di fruscio.

Aqui tenemos un previo para tocadiscos que esta muy bien para el precio que tiene, no vas a encontrar un previo de estos por este precio en otras marcas, es evidente que el previo no es un previo profesional, pero suena muy bien. La carcasa se abre como una tapa que gira con dos tornillos y dentro esta la circuiteria electronica y compartimento para pilas de 9v, yo lo tengo alimentado con una pila de 9v, cuando lo uso lo enciendo y al terminar de usarlo apago el interruptor de off para que no se gaste la pila. Si buscas un previo barato y que suene bien esta claro que este es el ganador aunque, se le pueden poner 2 pegas y las dos del transforamdor, uno que el transformador lleva una clavija de esas inglesas y hay que comprarle un adaptador, el segundo pero es que el transformador es de muy mala calidad y su circuito esta mal estabilizado, por lo tanto si lo usamos con transformador mete un ruido de fondo bastante molesto y es por eso que yo lo uso con la pila, a parte que es mas comodo y creo que la pila debe durar años, asi que la pega que le veo para mi no es ninguna pega por que no tengo intencion de usar el transformador.
