    I just got a Alembic F1X and a Stewart 2.1 , I believe I hooked it up right but it sounds like crap.Now you got to understand this is a new venture into the world of amp/preamp. I hooked the preamp full range out to the input side 1 of the amp flip the mono switch on the amp to mono and ran a speaker wire from the two reds across from each other as stated in the manual to a bergantino 2x10 at low volume with a modulus bass..and then to my six ten Ampeg, any ideas why ? My 300 watt Mesa sounds better..

    By connecting both of the red binding posts, you seem like you are trying to run in bridged mono. Check to see that the Stewart is rated into 4 ohms, bridged. A lot of amps don't like this load. Don't know if the Stewart has a bridge switch, if so, it needs to be engaged, if you want to run the amplifier bridged. Most amps have the bridge switch in addition to the stereo/mono switch. . This assumes both of your cabinets are 8 ohms. If either of your cabinets is less than 8 ohms, do not even try to run them both in bridged condition...you will fry your amp. A more conservative approach would be to run parallel mono. You would need to check your Stewart manual to see if this is accomplished via a switch or by using a jumper. This way, you would have your Bergantino on one side of the amp and your Ampeg on the other.
    Full range out on the F1-X is correct. Check out your amp connections and switches after re-reading the manual. It's really easy to be jazzed about a new piece of gear and skip over some important, but at the time seemingly small, point. Good luck!

    Well, just to check the sound, why don't you run the pre-amp through one side of the Stewart just to see what the tone is like? I doubt you're ever going to need 1,200 watts into a single 210 anyway.
