It really should just work. I haven't given my second-hand HD400 a try out on the Speakons yet, just direct, so I hope they work on mine. It's possible that someone used it with two 4 Ohm amps and blew the thing.
As you got yours from a store (I assume) then I would be tempted to return it while you can. I do love mine though already.
The other option would be to contact Support directly - but then they may advise sending away for a repair:
There is no way to apply software updates or reflashing. You can try resetting it if you like, but I think that just reinstates the factory patches. I think you hold A whilst powering up.
I assume you have 2x8 Ohm speakers?

Thanks for your reply.Today, I received a used Lowdown HD400 from Guitar Center for $299.99. Haven't had the opportunity to try it out yet. I would like user input into the question as to how well it produces "warm" tube like sounds or what settings can acheive this. I have read some great reviews about this amp and will put it through it's paces soon enough. I am using two 8 ohm speakers. One is a 1x15 rated @ 400 watts (Neo Acoustic); the other is a 4x10 rated @ 400 watts (Acoustic). Both have a mellow horn. I believe this combination along with the HD400 will be a match made in heaven. I have played through an Ampeg SVT with a 8x10 speaker and the warm bottom was "perfect". Also, I used to use a GK 400 B rated @ 200 watts and GK is known for the contour and "valve effect". I prefer solid state to tube amplifiers due to the longevity and reliability of solid state. I don't want the cost of replacing tubes when they go out. Hopefully, I will be able to produce some "sweet" tube like sounds with the HD400. In the opinion of the Line 6 users, should I expect to be able to get some similiar tones to what I have described ? Thanks guys for reading this post.
