-- Phono/Line Inputs??

Phono/Line Inputs??

Whats the difference between the phone input and the line input?? Is there a specific one i should be hooking my turntables up to??

Phono is at a lower level than Line in is.

Phono needs amplification, and de-noising (ground connection) in most cases too. Do not put a Line level input signal on the phono, it could be the end of some of your audio components.

Phono = Turntables


if you didn't get that by his responce.

haha. Thanks for simplifying

I have a turntable with line level output here, without a ground cable even.

only ones i've ever used (for mixing) had grounds.

:shrug:

yes I understand, keep in mind though that some turntables come with built in amps now, and don't need any ground connection or amplification at all.

Yes exactly, some of the newer tables come with pre-amps built in.

One thing that is kind of neat, you can actually play a record on your TT, and hear it perfectly (through your mixer and speakers), without even having the table turned on or plugged in.

Essentially the stylus vibrates from the grooves in the record, causing a vibration to occur bewteen a coil and some magnets in the cartridge. This induces a current, which goes straight out the RCA leads of your turntables. Since this output is so weak, it has to go through a pre-amp to pump it up to line level (and do some other things, according to the RIAA standard).

That sounds a bit odd. How can it work with no power?

I know my old 1210s (MKII) used to generate a sound if you manually rotated the vinyl with the power switched off (I think) if they were plugged into the mixer. And they had no preamp as far as i was aware...... or do they? Thought MKIIs were first invented in 2038 BC?

Ha, well you DO have to rotate it by hand

I guess it's not really THAT interesting since the original gramophones were completely mechanical, it's just kinda neat how it translates the grooves into electrical impulses using induction.

None of the Technics have pre-amps built-in (as far as I know, unless the M5G does, but I doubt it).

It's really not "a good thing" to have pre-amps integrated into your turntables. It's a convenience thing really, no ground cable, no needing a phono input on your mixer, etc.

Certain mixers are known for having really great pre-amps: Urei 1620, Bozaks, A+H's. So if you have one of those mixers, it probably behoves you to use them.

the new numark turntables dont have grounds

Most decks these days that are not technics don't have the annoyance wire.
