remind me..a audiophile question..

[vash]

ok..it has been a long time since i had a home stereo. too many years living like a gypsy, i guess.

well. i got some old stuff. Denon 550 stuff..the Denon has a "phono" function..remind me why only a turntable can go into the input..

sorry if the que is retarded..but it has been 20 years for me..

I think it has something with the turntable not having a pre-amp. But i may be wrong

[tchanson]

Unlike other line level inputs, a MC/MM phono cartridge has a much lower output level. It requires additional amplification to bump the volume levels to be similar to other input sources. That's what a phono pre amp does.

Phono inputs are not line level, have their own internal amplification and equalization to compensate for a turntable. They have to be grounded to reduce the noise on the low level signal.

Phonograph needles output must be ran through a specific internal EQ in this preamp to bring the low frequencies back to normal state and cancel noise. Plugging a line level input into a phono jack will be loud, clipped, and distorted most likely.

cool..thanks.

i was going to "experiment", but now i dont have to..

Make sure your phonograph is well grounded. You'll have all kinds of hum and rumble if not.

thanks..i was wondering about the ground lug on the back of the unit..
