How soon is the price going to be jumping?

I really need to get a good comparison between this and the DBX though...but that's for another thread I suppose.

I will say that this PSU looks very well designed. Makes me wonder if you would consider building a higher wattage PSU for CarPC purposes...

The price goes back to $139 (still free shipping in CONUS) on Oct 20th. Go to www.ezamps.com and send me an email through the contact form. I will give you directions on payments. I currently accept Paypal only, but will be accepting Visa/MC in a few days.

Hmm. I thought there were already PC supplies for vehicle use. I guess you would know better than I!

[RedGTiVR6]

There are already PSUs for computers, but non of high wattage. 350 watts at the most currently.

I'll have to see if I can come up with the $800 I'll need to buy two PSUs and 2 Behringers before October 20th then!

Here they are! These are the final revision of the DSPower boards. I thought I'd scan one in to bring some excitement to the thread (as if there wasn't enough already)!

The photos depict the top and bottom layers of the raw (pre stuffed) boards that hold a few features you won't see one you receive the boards. They are gold plated, blue soldermask (matches the Behringer for extra points!), covered vias. Any of these terms can be searched through Google. The boards themselves are FR-4 fiberglass 1 oz copper. I used all SMD components EXCEPT components that are notorious for "falling off" the board in vehicles. SMD filter capacitors, inductors, and the transformer are through hole mount for the best possible reliability.

You will see a couple integrated pieces to the upper and lower right. That is a key fob "gift" included with each power supply. The other is the terminal input PCB. I flipped the image over in Photoshop without mirroring the image so...there is text on the fob's reverse that says The Ultimate Audio Experience www.envisionelec.net

I hope you enjoy these! The preorders ship Friday!

Well done! I certainly wish you the the best of luck with your products. You deserve it. Not many have the drive and guts to financially extend themselves for the DIY community. You are a true example of dedication.

Along with Npdang of course

[Whiterabbit]

I love the excitement readable in your post. You can always tell an engineer, especialy one who loves his work...

they ship friday? I havent paid yet, has anyone else? did you get my email? do I need to send it again?

[scott_fx]

i can't wait to get this all set up! i'm so psyched!

I probably got your email, but unfortunately, my webmail doesn't pick up ezamps mail. As many of you know, I have a full time job from which I am afforded the luxury of internet access and a lot of nice test equipment. Everyone that has paid will be getting their's sent out tomrrow, with the exception of a few international order which will go out on Monday due to all the extra paperwork involved. I think there are ten or so going tomorrow, plus any last minute orders. I accept Paypal at
envisionelec_ at _woh.rr.com

[Whiterabbit]

You said youd be able to accept cc directly in a couple days? I can wait.

[envisionelec]

Eh..I didn't see an email from you. Did you send it through the contact form, or are you waiting?

[Whiterabbit]

sent it direct to aaron@ezamps.com

just a small text blurb expressing my desire to get on the preorder. shall I resend it?

Uh, maybe they took that one offline. There might be a Spam filter on "direct" mail.
Your best best is to hit the Contact Form on the www.ezamps.com website.

Do stickies only last a few weeks?

I have a couple questions about the setup of the Behringer.....

I will be running a Nak CD-700ii, which uses Female RCA outputs. There is one per channel. How should i wire this thing to the Behringer? I was thinking 2 channel RCA to XLR cables, which would match up with the 3 inputs. Someone had mentioned that the inputs are not hardwired to the outputs, so I know that i don't necessarily need to use all of them this way but i figured it would be a bit more straightforward.

on the output side i have a couple choices....to use a similar setup with the same kinds of 2 channel RCA to XLR cables to match up with my amps, or 6 unbalanced RCA to XLR, correct?

I think i have it figured out....but i am curious...is there an advantage to doing this one way or the other? Any responses, please be simple and explanatory....pardon my n00b status, but i am especially amateur when talking about balanced to unbalanced cables and the flexibility of the processor's inputs and outputs...

On the input side, you have three input sources, but they can be linked together at the outputs. For example, your NAK would connect L and R to channels A and B (C would be empty unless you have a subwoofer output on the NAK). The outputs are discrete, but can be made in tandem for a stereo setup. For instance, channels 1 and 4 would be Left and Right Lowpass (or bandpass), channels 2 and 5 would be Left and Right Highpass and Channels 3 and 6 would be Left and Right Lowpass (or Subwoofer output). I have it connected with the separate subwoofer input since I enjoy having control over it. You can easily tie the "C" input to either A or B, likewise you can move the output channels around so they correspond to A, B or C - on the fly.

Does this help?

By the way, don't worry about "balanced" or "unbalanced" inputs (same for the outputs). The Behringer happily accepts either signal type with no loss of signal gain. I will have a large FAQ on my site that will explain how this works - and there might already be an answer in this thread that explains the 'servo' action of the Behringer's inputs and outputs. It is recommended that you tie pins 2 and 3 to Ground at the Behringer and use Pin 1 for signal input on an XLR plug.

There's a diagram on that in the manual if you need more inf.

Are these currently available?

Yes, they are. Please send me a PM for ordering information.

I was hoping some folks that are using the DSPower would be replying to this thread, but maybe they're too busy enjoying their systems!

[Whiterabbit]

definitely too busy enjoying their own systems, family, food, etc. It's thanksgiving!

They are absolutely sweet though. rugged, noiseless, and they work. They do what they are supposed to: Dissapear into the stereo and be a work-horse you never have to worry about or think about again.

Which is why I bought that third one

Hi
This power supply works with the Behringer CX3400?

Unfortunately, the CX3400 does not have the specialized switching-power supply that the DCX/DEQ models have. It contains a basic toroidal transformer which will work fine with a standard inverter under most circumstances*

*Note that some folks claim/test that the DCX2496 works well with an inverter - but, honestly it doesn't work noise-free in all circumstances in real world applications.

[Whiterabbit]

the behringer powersupply has its own behringer part number: PSU2496.

I suspect Aaron's power supply is compatible with any behringer product model that ends in "2496"

Just a guess though.

the only problem with toroidal transformers is they dont deal with DC at all... if there is any dc coming out of the inverter for any reason it saturates the toroid and you get nothing on your secondaries :eek:

neat product, i might have to pick one up

i have modified my DEQ2496 quite a bit for my headphone setup (new balanced output sections etc)

No transformer deals with DC, I can't think of why an inverter would make DC, it would be tough.

He's talking about an offset which is correct: toroidal transformers don't deal well with offset which leads to flux imbalance. Generally speaking, a mobile inverter deals with one load at a time; Neutral currents should be balanced. It's those pesky low PF loads you have to worry about.
