Turntable Volume? |
|
|
I'm a newbie to the group, so I might have missed this if it was
addressed before... I have a Technics 1200 turntable that does not
have a pre-amp. It is connected to a phono jack on a JVC amplifier.
When recording to either the tape deck or the CD recorder, the music
recorded from the turntable is much lower in volume than a CD. I've
heard (don't know if it's true or not) that getting a pre-amp would
solve the problem. Can a pre-amp be purchased and connected inline
between the turntable and the amplifier? The turntable wasn't cheap
and I'm not in the market to upgrade it.
Does anyone have any ideas? Thank you.
JoAnn :-)

If the sound is very quiet and has very strong high frequencies |
and no low frequencies, then you need an outboard phono pre-amp.
If the sound is normal, but a little quiet, then you don't
have a problem. Blame the people who use lots of compression
on CDs and radio for how loud they sound compared to your
turntable.
Hope this helps,
Peter.

The jack is specifically labeled PHONO and there is a ground for the
turntable as well. I talked to radio shack about it once and they told
me that I had to buy this smaller amplifier (that they called a preamp)
and connect it between the turntable and the JVC amplifier. I did that
and the results were clearly wrong. Can a preamp be connected inline
between the turntable and the amplifier to boost the signal? |

You do not need a phono pre-amp, because it is built into your JVC, and
it probably would not make much of a difference in the volume level
anyway. It's quite common for turntables, even after pre-amplification,
to still be lower in level than standard line-level inputs.
Your problem isn't a problem at all. Just turn up the input levels on
your tape deck, and you'll be fine.

Maybe you tried an additional phono preamp (would make music VERY bassy and
dull), instead of a 'MC preamp' , if your cartridge is indeed MC.

Maybe you have a MC (Movoing Coil) phono cartridge than requires a
transformer or additional low noise linear preamp before the phono preamp ?
As opposed to a MM (Moving Magnet) cartridge that goes straight to 'Phono'.
Or maybe you are comparing perceived audio levels on highly-compressed music
as on many recent CD releases.

Let me add to Peter's thoughts on this. If the sound seems normal, but is
quite low both when listening and when taping, then you probably have what
is called a "low-output moving coil cartridge" in the Technics. In that
case you need what used to be called a "headamp" or a "pre-preamp". This is
essentially a low-powered amp that boosts the signal to sufficient volume
for the preamp that is built into the "phono" input of your JVC to handle.
Probably today the best place to look would be on eBay. Look under the
headings "step-up transformer (a variation)", "pre-preamp", "headamp",
"moving-coil step up".

Mebbe but unlikely. That's why I asked him in my original reply what
cartridge was in the TT.

Not uncommon; the output levels from consumer equipment are not very
well standardized. I'm told that some amps/recievers with digital
controls will let you program a volume offset depending on which input
you've selected, to compensate for this... but since volume also varies
from record to record and CD to CD, there are obvious limits to how far
this will get you. |

In that case, the output of the phono cartridge you have (what model
is it?) is too low for the gain/amplification of the phono stage.

I wouldn't be so sure of this. All she's said is that the output of the
turntable is lower than the output of her CD player when she records to
tape. That's fairly common. If she had to crank the volume *way* up
even to listen to the turntable, then I'd agree that there's a problem.

Or you can simply live with the discrepancy and just turn up the phono
when you need to.

That's how I deal with it.

What was the name of this input? If it was not "Phono" then
it was likely a line-level input and I'm surprised you were able
to hear *anything* out of it.

If you don't have an input specifically designed for "Phono"
then, indeed, an RIAA phono preamp is required.

Yes. There are several sources of standalone phono preamps.
You can buy one at Radio Shack (# 42-2825) |

I don't have model number information about it, but it is an
Audio-Technica cartridge. The sound is normal, just a bit lower volume
than the CD. |
