No bass with new turntable?

 Hello, I've just set up a Pro-ject Carbon DC Esprit, dialed in the arm etc., and while the upper spectrum of the sound is great, there is just no bass, let's say below the 80-100hz range. It's been probably 30 years since I've fooled around with turntables so I can't remember if that's just the way it's supposed to be. Luckily I have a Velodyne SMS-1 bass management system to turn up what I'm missing, but without that I'd be completely disappointed. Using a CDP my speakers are very full of bass. I've played with the tone arm adjustments with no difference in bass really, all supplied cables hooked up and checked, the cart is an Ortofon Red, the phono preamp is integrated in the Rogue Audio Sphinx amp.
 Any suggestions/opinions?

Wetfeet48,

In your initial post you said you just set up the table and there is no bass. Inna has a point - initially there is not much bass. 

It does sound like you have the channels out of phase, even though you checked. This could occur with a mislabeled connector anywhere from the cart itself to the phono stage. To check for this condition reverse the wires on one channel and see if the bass comes in.  You can do this at the cart pins by switching the tags on the pins - either red/green or white/blue. 

Regards,
