A little birdie just told me that the Model 200 draft manual is available for perusal. Follow this link: http://pdf.outlawaudio.com/outlaw/docs/200manual.pdf

Thanks for the link!

The section about heat and ventilation doesn't seem to clearly state whether it's OK to stack these amplifiers up or not. It suggests one can (by talking about not putting things in the middle of a stack), and indicates there's ventilation from the bottom, which suggests the feet are high enough to provide sufficient ventilation between multiple amps in a stack. Sound right?

The specs page on the main website says that there are two RCA input jacks, but the diagram of the rear panel on page 4 of the manual shows only a single input. On a possibly related note, the manual makes no mention of bridging two amps together. I take it this feature got dropped?

In an email from the Outlaws I was told you "could only stack two units at a time due to heat ventilation and weight factors."

Thanks for the info, obie. I figured there had to be a limit, but I would have hoped it would be more like 3-4 units in a stack. If the issue were just ventilation, it should be possible to add some kind of spacers to leave more of a gap between units in a stack, but there's not much to be done about the weight.

The fact that the M-Block is only 1 rack unit high sounds great, but if you can't stack more than 2 of them, and they don't have brackets for rack mounting...

I wonder how performance/heat dissipation would be affected if, instead of using it in the normal "flat" configuration, you were to rotate it 90 degrees so that the "side" now becomes the "bottom"? You could slide a whole row of them together then with no concerns about weight.

I don't know about putting them on end. Off hand, I would not recommend it since the cooling path might be comprimised to some extent. I would call Outlaw about that one.

Hmm, can only stack two at a time... can only trigger two at a time... Doesn't sound like they're going out of their way to make these things useful in a 7.1 system...

Matthew:

They may have said that you can't run more than two units off the trigger, but there is no reason that you can't put them in the "music sense" mode and run as many units as you want with auto turn-on.

I wonder if anyone asked them about the stacking. Is there some specific height that you can use between units so that you could stack more than two and get the needed coooling?

On the other hand, while it sounds neat, one has to wonder if this type of product is really meant to be used in a stack of seven or eight. Me thinks a multi-channel amp is the better route for that.

But what do I know, I'm only a dog!

Update:

While we were being somewhat conservative with our recommendations, the sheer weight of these units really limits the stack to three units. More than three units does increase the risk of heat or weight related damage.

The trigger will accept as little as a 6 V DC 4 mA signal. However, since many of you will likely be using higher voltage and mA triggers you should easily be able to trigger seven or more of these amplifiers.

Best,

If a person were using an actual equipment rack that would eliminate weight concerns. I wonder what sort of spacing or ventilation requirements would exist on a setup like that. I guess it would also make a nifty sub amp for the 1050 if you have a passive sub.
