[brenner182]

bump. because i am off today. lol

[brenner182]

nothing? anybody?

[rpsands]

There is no better bargain in power amps right now

That said, if your cabs come out to a 4 ohm load, I'd consider getting the XLS1500 and bridging it. There is no need whatsoever to biamp with your setup.

[brenner182]

you know, for some reason that idea never even crossed my mind. thats a really good idea.

[BigOldHarry]

Interesting: I just read a piece in some A/V pro magazine while at an office, about the top-rated power amps in professional A/V settings (arenas/convention centers/ect). By far, Crown was the champ...

If you can afford it, buy a crown. I'm not a Peavey fan.

[brenner182]

thinking even more about it the 1500 would make alot more sense(my gutar player explained it to me when i asked his opinion)

while it only will do 525 @ 4ohm i can bridge it and have 1550w

but if i was going with the 2500 i could only get 775 max. if i bridged it holy hell. 2400watts would explode everything.

and 359.10 looks alot better than 540 bucks

[rpsands]

It's probable you would be fine with just the one side at 4 ohms, but bridging would make you less likely to engage the limiter at any point which I find to be a good thing for power amps ("headroom").

note: If you are going to bridge, be sure you get a bridge wired speakon cable or wire it for bridge. the XLS series has had some hilarious reports of people saying the 1000/1500 provided no extra volume when bridged, only to find out the people were not using a 1+/2+ cable.

[brenner182]

from what i read in the manual it just runs off of side one if you are using the speakon cable

[OldHack]

Those DriveCores look really good. The limiting sounds good too. Well, I haven't actually heard the limiting but it keeps you from hearing it hitting the rails if you ever get there. Crown engineers their stuff to not fail. Something some amp companies don't put as high a priority on.

That's what it sounds like until you read the fine print. And I quote:

"b. If using a Speakon® connector, connect the positive terminal of the speaker to 1+ and the negative terminal to 2+."

Normal speakons are wired 1+/1- to 1+/1-. For bridging with some power amps you need 1+/2+ to 1+/1-.

The binding posts work fine with a banana to speakon cable too though.

I paid $540 for my MarkBass LM3 800.

(That's the Littlemark 3 with 800 watts of power)

Got it at Guitar Center on a weekend discount promo which they seem to have every weekend.

It powers 2 Avatar B410 Neos without even breaking a sweat.
Powerful - Tonal - Hugely Loud - any sound I want is available from bone-crushing, breathtaking bass, growling dinosaurus bass, to smooth jazz tones round and mellow,

Instead of a volume control it has a Richter Scale (normally reserved for earthquake measurement) - just kidding.
But it could happen!

Where would you even find that sort of cable?

[rpsands]

A normal 4 pole speakon (NL4), a sharpie, and a screwdriver. Write "A" for "amp" on one side with the sharpie, then open it up and move the 1- end from the amp side to 2+. if it's not obvious which one is which, consult master google for pics.

The banana to speakon cable is easy to find, used a lot in DJ environments.

Fairly sure those cabs can't use any more than the IPR current available can give.

[brenner182]

The new Bassman 410 cabinet was designed to provide a quick and punchy tone. And with 700 watts programmable power (350 watts continuous) at 8 ohms, four 10” Eminence speakers and a compression driver horn with full attenuator, it's ideal for medium power usage

i plan on getting another one to match it as well

So you mean to tell me you can just slide a switch in it?

[brenner182]

i did not know they were held in with screws i thought they were soldered in.

[rpsands]

Its not a switch it's a screw yeah. I have never seen speakons soldered before, just stripped wire held in by a screw.

[brenner182]

this is why i love talkbass. i learn new stuff everyday.

that explains it. kinda, would you have to rewire both ends though? or just the one end?
