Who makes dual mono amps

bassix67 · #1 03-02-2011, 09:31 AM

Hey guys, can anyone tell me besides Eden & Carvin, who makes dual mono bass amps. I'm running two Acme 4ohm B2's and want to run them stereo not chained. I'm looking for 500 or so a side.
Thanks
B.

You could use just about any decent stereo power amp with a pre of your choice. I'm using a Carvin BX1500 to drive mine.

Genz Benz Shuttle Max 12 is a nice option for what you want to do. However, as I think you know, it would not be 'stereo', but rather just a mono source driving two separate power amps.

I think stereo was the wrong word. I just want to run both cabs at 4 ohm.
I love the Ideal of the bx1500 but it's to wide. I'm not crazy about Heads that hang over the sides. Reminds me of muffin tops lol!!!

You want to run the amps in parallel. My system does NOT look like a muffin I'll have you know my lad!

So you want an amp that can run 2 ohms and has two speakers outs?

That would work, but he prefers to run separate power amps, each at 4ohms. Just a different way to get to the same place, and some feel a bit better than driving a single power amp hard at 2ohms.

Yes I want to run the cabs with two separate(dual mono) amps. I'm leaning towards the Ashdown little giant 1000.
I really don't need and amp that bridges.
I do jazz, fusion, r&b and wedding/Corp gigs. So 500w per channel is enough to
Drive acme's.

I had the acoustic image focus but I like to be able to use 1 210 in small venues and I just didn't feel comfortable sending 800w to my acme b2 which I love.

What would be the benefit of sending different amounts of power to each cab? If you aren't running stereo (two different signals coming out of each cab) then you might as well just give them the same amount of power from a single amp.

I think what you want to do is run both of your cabs in parallel with a mono amp at 2ohms.

Mainly amp manufacturers, you sell twice as many amps that way!

I would say just about any stereo power amp on the market would run each side at 4 ohms all day long without breaking a sweat. A stereo amp IS essentially dual mono amps in one chassis.

It'd be a lot different if he didn't want separate amps. Its a lot more exclusive club of power amps that'll run parallel mono and support a 2 ohm load. Nobody I know of will handle 2 ohms in bridge mode.

I don't mind a mono amp but like I said I like the option of using just one 2x10 cab on gigs and putting the other on top when I need it.
Can anyone tell me a mono amp that goes from 500w at 4ohms to 1000w at 2ohms?

I don't want to send different amounts of power out. I want equal amounts which is what dual gives me. With single mono, if I'm running one cab its getting slammed
With to much wattage at 4ohms. Right??

You really need a bigger PA not a bigger amp

If you can find an old stereo Trace Elliot head it'll do dual mono with two channels @ 4 ohm.

Or just go seperate preamp and stereo power amp.

Or do everyone a favour and use the FOH system.

EDIT, cabs get slammed with voltage not wattage. Cranking the amp with any rated amount of load connected will give you roughly the same voltage but the power drawn from the amp goes up with more cabs. At least with a solid state ampo it does, not too sure about valves.

The big Stewarts are true dual monaural amps. Seperate power supplies; the only things they share are the power cord and the box.
The spec sheets don't show it, but according to their tech department they are stable mono or bridged at 2 ohms, and I've yet to have one fail or even really breathe too hard at 2 ohms in use.

Walter Woods stereo Electracoustic amps can be run in a variety of ways given the pan controls for each channel.

Any amp rated for 2 ohm and 1000W, roughly 500W is what it'll push through 4 ohms.

It's the 2 ohm rating and whether it really will hang there that is the big question. It's really tough on an amp to do 2ohm.

+1 The key here is that there are very nice lightweight solutions for exactly what he wants to do. The Genz Shuttle Max 12 is, as you say, basically a typical 'stereo amp' with a dual channel but mono preamp. Perfect power for what he needs, VERY nice EQ control of the low end, which is key with the Acme's, and a somewhat bright voicing inherently, which also IMO makes the Acme's sound good. And, at around $1,000 or so and well under 10 pounds, it is a killer deal. Combined with the Genz service, that particular head would be a nobrainer to me for what the OP is trying to do. It is kind of the 'new Eden WT800' to me. IMO!
