Hello,
I recently picked up a used equalizer, and decided to hook my turntable up to it for a better sound. However, when I run the turntable through the equalizer (a Pioneer SG-9) to my receiver (Sansui G-8000), it produces some hiss when the volume and considerably more hum than when I had the turntable connected directly to the receiver. Any ideas on how I can correct this problem? Thanks!!

Sure. One more time (the software ate my last reply).

The output of the turntable is a low voltage (a few millivolts) which needs to be amplified and equalized by a specialized phono amp which is what your receiver has at its phono input.

The EQ, otoh, is a line level device (about a volt). So if you feed the turntable into it, the very low signal is combined with the inherent noise of the EQ and both are then greatly amplified by the phono stage of the receiver.

What you need to do is to re-connect the turntable to the receiver's phono input. Then, if you want to use the EQ, connect it into the receiver's tape loop or, if it has one, its processor/EQ loop. Then you can switch it in or out, as needed.

Why do you have an equalizer? Also, buying a used equalizer could be your problem. That is, the equalizer is bad.

Thanks for your help Kal. I solved the problem. My receiver does have a tape loop button, but it's labeled as "4CH/NR Adaptor", which had me confused. Thanks again.

To compansate for room modes of course.

The SG-9 is far, far from ideal for this application since you cannot adjust frequency or Q. Also, it has too few and fixed frequencies. A parametric is needed.

Maybe his room has a problem that is at one of the equalizers frequencys and has the same Q as his equalizer.
It could happen.
I always loved visiting friends that had EQs in their system. They always adjusted them based on the appearance of the display. Looks cool, huh? Give someone more bands and sliding center frequencies with variable Q and see how bad they can set it.

Rane on it baby PERFECT "Q" or Proportional "Q" this ain't no BSR/ADC tone control. http://www.rane.com/swf/deq60lfp.swf

Is that page supposed to do something?

Picture of a nice equalizer that fufills the idea of controlling in subtle pieces, to control a room.

Much better than the GS-9 but hardly ideal for room correction. This lacks those same capacities listed above and cannot be adjusted as critically as can a good PEQ.
