    Ok, now that I've kinda decided I'll be getting a rack system to power my 8Ohm 410 cab I'm getting deals from shops and these two do seem rather tempting:

    Sansamp RBI
    QSC Powerlight PL 1.4 (used)

    or

    EBS-1 (used)
    EBS EP800 w/ SKB 4U RACK (used)

    I'd like your opinions on which of these would seem a more sensible option. I play mainly heavy metal.

    Also, any thoughts on the QSC PL series? I've never heard them mentioned in the bass playing community, and new they seem to be a bit pricey. However, their power ratings (1400W @ 8 / 1000W @ 4 bridged) and weight of 18lbs / 8.2kg are tempting.

    Thoughts?

    I'm not familiar with this EBS unit, but I can tell you that if it's anything near what the Fafner or HD350 is, you're far better off with that than the SansAmp.

    Bob,
    I was looking at the PL manual..

    What's with the "“Touch-Proof” binding posts"? No conventional output connectors?
    I'm confused.

    Hei Fangry,

    How much more conventional can you get than binding posts?

    Now I feel a bit embarrassed :)

    It's just that I've never seen but 1/4" and speakon connectors, my cab has 1/4", and am wondering how do you connect a cab to the amp!

    Poweramps in general don't seem to have 1/4" outputs.

    That's true; power amps seldom have 1/4" outputs any more. There's good reason for that! ;)

    With binding posts, you have several options for connecting the speaker wire:

    1. Loosen the barrels of the binding posts. Strip the ends of the speaker wire about 13 mm. Insert the wires fully into the side holes of the respective binding posts. Tighten the barrels so that they clamp onto the wire securely.

    2. Same as #1, but affix a spade lug (12.9 mm wide, with 6.3 mm slot) onto each wire. This applies to PowerLight amps made since sometime in 1996, when we started using binding post connectors with slots to accommodate spade lugs.

    3. Use a pair of banana plugs (or a dual banana plug). On amps sold in the EU, the end holes of the binding posts have plastic plugs inserted due to CE safety regulations, but you can insert banana plugs into the side holes.

    Thanks a lot, Bob, as others have often said, it's good to have you here :)

    I just got a bit worried not being able to stick a regular speaker cable right in the back of an amp... but I'll definitely consider the 1.4. Looks good.

    A vote for the RBI...I'm constantly impressed by mine.
     
  10. Is it versatile enough for you?

    I've been wondering about the RBI. Everyone's saying how great it is and recommending it to anyone, really. But I must have missed on what the point really is, besides tube emulation (bet there isn't one :) ). And just is it suitable for my heavy rock application.

    I have a SABDDI used as a pre (basically same thing) They have decent EQ, good sound (from "hi-fi" to warm/gritty) and are versatile. You should like it for heavy rock :D

    What's your point? ;)

    It's a preamp with a tube amp emulator, and it can do a very nice SVT sound, among others.

    Point? Oh, I seldom have one. I'm usually like that, confused and not really even knowing what is it I wanted to know ;)

    Ok, that's what I wanted to know.
    Sheesh, here I go again bothering people with my "everyone says it's good; is it good?" questions :)

    does the sans amp bass driver (stompbox version) have enough juice coming from it to drive a qsc amp?

    bob lee was going to find out a while back. if you posted without me seeing bob, i'm sorry.

    some folks say yes, some no.

    anybody?

    no, the di box version of the sansamp doesn't output very much voltage. It is my understanding that the boxes can be easily modified to run straight to a power amp and effectively, but that depends how technologically inclined you are. the rbi rackmount version outputs at 0db though, and requires no modification

    I've also heard that driving a poweramp with a SABDDI can be an iffy thing.

    For QSC, I think Lord Valve will modify new poweramps bought from them to require a lower input voltage to drive to peak - Bob Lee, can you comment?

    Anyone with an answer for the original question?
