Default OEM Digital Crossover now Available to Diy Market

A serious OEM digital crossover controller is now available to DIYers. Its the Xilica xm-2040 which is 2 inputs and 4 outputs. One unit will run a stereo pair of two way speakers. or a three way plus sub, or a four way. These have a lot of DSP power and can do all kinds of crossovers, notchs, Parametric EQ, time delays, etc.. They are built with the best audiophile components like the Crystal Semiconductor CS4398 DAC. This is board only (runs on +_12V. Power can be drawn from the DC bus of an ICEPOwer or from an AC to DC switching power supply. It comes with great software to control everything. These units sell in Holland for over 500 Euro. I have a number of brand new in box units with a RS232 interface I would like to sell ASAP. I am asking $300 each plus shipping. I'll give discounts for larger orders. E mail me for details. I take paypal and I want to sell all of these by the end of the year. Quantities are limited so don't wast time. When this lot is sold,there wont be any more at this price.

Contact me at delphinj@aol.com. The modules are in NJ.

Thanks.

Looks very interesting. Is there a link to the original factory site to learn more about the units? It would be helpful rather than drop a hundred questions here.

The website say precious little about the specs. What kind of analog output stage does it have? If it has opamps what type? Is the controller software for it available? etc.

Hi

Where is the optional (needed for a modern PC) *USB interface available from, $?
How are 12 pin Euro outputs converted to normal RCAs?
How did you get them?

Thanks

Hi,

Thanks for your interest in the crossovers. I'll try to answer all preceding questions in this post.

1. The xm 2040 comes with an RS 232 interface. An optional ethernet is available from Xilica. (a USB may be as well, I don't know). The 232 is quite common (even these days) and works very well for this application since its pulls very little current from the PS. I use an external USB to RS232 cable to program the units with no trouble at all with modern computers.

2. The output of the XM 2040 is balanced. The Euro 12 pin contains screw down terminals that accepts bare wire for 4 channels. The positive (hot), the negative (cold), and the ground for each channel. When building this into a speaker or its own enclosure, you simply wire each output to a corresponding XLR jack (or RCA using just the hot and the ground).

3. New firmware and software is always available on www.xilica.com. (ie. latest release has FIR as well as IIR filters).

4. The chips used in the unit are as follows:

ADC: Cirrus Logic: CS5361
DAC: Cyrus Logic: CS4398 (2)
DSP: Analog Devices ADSP21363 Sharc
Buffers: JRC 4580's
Clock: CQ12-288

5. They were bought directly from the manufacturer, Xilica Audio and are new in the box.

Are there still some of these modules available? I'm getting closer to being able to afford one, with a couple of more sales, I'll be there.
