I'm sorry, I know this is very amateur of me but I'm really frustrated.
I just bought all new gear (owned similar gear 20 years ago - now back in as a hobby) which includes:
(2) TEchnic 1200's
Rane TTM 56s mixer
Yamaha r-s300 receiver
Martin Logic speakers.
I can't get any sound out of my speakers. I bought a yamaha rx-v371 amp a few days. Wasn't getting any sound and was told I needed a preamp. They were right this amp didn't have a phono line. Then I bought NAD Phono Preamplifier but couldn't figure it out. The only way I could get sound through speaker was if I hooked up one turntable to the phono amp. It had two phono inputs but just one ground. One turntable wouldn't work.
Figured it would be best to just take both back and pick up an amp (yamaha r-s300) that had a phono line. Thought this would solve all my problems. But still no sound through speakers (and only one turntable working through headphones). Very frustrated.
The way I have things set up right now is like this:
Both turntables plugged into phono lines and grounded on Rane Mixer. RCA cable running from Rane mixer to phono inputs on amp.
Please, please, please help me. It's been torture to have my new gear for five days now and not be able to use it.
Thanks.
