Good job Giskard. But I can't view it. My computer says that it is not able to process it. It's the Korean language programming on top of my essential non geek status.

Can you tell me:
Is the DX 1 basically like the BX 63?
Does it have a wall wart power suppy?
Are there any controls such as output level or defeat?

Thanks in advance.

BEing from Australia, would these crossovers be easily converted to 240V as I noticed in the schematic it was made for 110v?

Cheers

I opened the OM pdf and noticed the journalists aren't embedded, ooops, I mean the graphics aren't embedded in the document.

There are only two user-accessible controls. Power switch and low frequency level control. Looking at the schematic it's basically a 5234/5235 style network that uses crossover cards. One pair of stereo inputs, one pair of stereo HF outputs and two sets of stereo LF outputs, one of which allows for bridging/strapping power amps. Power supply is built in.

Sure, any service center down under should be able to set it up for 240 in a couple of minutes.

I sent convoy Australia and e-mail about getting the DX-1's in, so I'll see if the actually send a 240V version ready made!!!

Thanks for your info!

Giskard, is it true that there is another copy of the scematic floating around that is not the real DX-1?

I can show you a picture of the box its shipped in!!! That's pretty exciting isn't it?

I have yet to come accross a picture of this x-over, but the box should at least give indication of its physical size.

Don,

As far as you're concerned, this particualr dx-1 has been dsigned for the XPL-200's?

Those DX-1's were designed for the XPL200. JBL's current litterature states that there is a DX1 for the k2-S9800. To be honest, I don't know what that is.

Around six months ago, I stirred up our forum by posting that picture in response to someone looking for a DX-1 like you. This caused a number of people to contact Harman Consumer looking to buy them. After initial denials about the unit's existance, a couple of people reported that Harman did make them available for sale. I never did hear from anyone who actually bought a unit so I have no idea whether they were left over stock from the XPL days or a new unit for the S9800.

The units in the previous picture are definitely not for sale. This is a picture I took in 2001 of Greg Timbers in the Harman Consumer Engineering Lab. Last month, I asked him about the units since they had caused such a stir on our site. He stated that they are used strictly for development. He thought there were about seven units left when we took the original picture, but they are currently down to three. They tend to dissapear at the conclusion of each project.

Don,

Since I initiated this thread, how about pulling some strings for me and get a couple of DX-1's put aside for me to order ;)

Don, ask Greg to get the goofy look off his face and turn around and get one of those DX-1's off the shelf.

The goofy look is totally due to my digital camera. With its proprietarty DORKIFY™ image processing, it turns just about anyone into a goofball.

Actually it is a result of the camera's use of a "preflash" to determine correct flash exposure. This inital flash seems to ensure that people's eyes are at best half closed, and at worst, fully closed when the exposure is taken. You should see what this shot looks like at its original resolution of 2600 x 2000, with Greg's face filling up 19" monitor.

As to taking a unit off the shelf, see above.

If you go through the XPL series brochure they have one in one of the photo's. Can't see to much.

Don,

I have read from review on the internet about the DX-1 crossovers for the XPL 200's that the crossovers in the two versions (The USA version is black lacquer while the european version is walnut) are completely different and they do not sound the same.

The USA version is designed to be placed close to a wall while the european version is designed to sit in the middle of a room. The crossovers can be modified to either standard.

Can you or someone with knowledge of this can verify this?

Cheers
Mark
