Hi Guys (and probably Gals),
After several months of delays, I am announcing that the
DSPower! supply from Envision Electronics is ready for preorder. I am manufacturing the first 40 by hand due to upstart expenses being a bit costly to support right away. After all, I'm not a big company and my current resources are limited. I expect to be shipping the first orders by Sept 14th.
The introductory cost is $119 (normally $139) including free shipping to the CONUS. My site is being completed for this sale, and will be online by the end of the week. I just need to get a headcount of those immediately interested and ready to purchase.
Please send your inquiry, along with any questions to
envisionelec_at_woh.rr.com
I will return your email with information regarding your order and how to place the order. I will also send you the link to the new webpage http://www.envisionelec.net when it is "online".
As WhiteRabbit (Steve) at DIYMobileAudio.com has posted in the original DCX Mods thread the units perform noise-free and reliably.

I sent Steve a pair of the supplies back in June to use at Marv's BBQ gathering in California and for general beta testing. Although Steve's setup is highly unusual, with the 'guts' of the Behringer processors strewn about the interior of his trunk and passenger compartment, Steve reports excellent performance of the DSPower. Preliminary pictures of the unit are available at these links. These are mere prototypes of the final units, although appearance and performance are similar.

Needless to say, I am very happy with the engineered performance of these supplies. They emit very low levels of EMI, relegated to 2MHz. You can place a portable radio within 6" of an unenclosed DSPower and be able to pick up any AM or FM station without added noise or interference.
Let me go over some of the features of this power supply which is designed to directly replace the AC input section of the Behringer DCX/DEQ2496:
1.
True Plug and Play Operation. The installation takes less than 15 minutes to perform. The supply fits the OEM chassis frame and includes a terminal block for 12V attachment. No drilling holes. No cutting wires. Installation is 100% reversible.
2.
OEM JST jumper connector. I went to great pains to buy the original design connector for this power supply. It is a 75mm long JST PH-terminated connector with a board-in and wire-to-board connector. Simply put, the supply will plug in just as easily as the OEM power supply.
3.
Low-noise, slow-risetime switching operation. Fast-switching edges produce the most radiated high frequency noise into a conductor, whether a wire or the air. I've developed the supply and magentics (transformer) to give a trapezoidal waveform that slowly switches on and off to significantly reduce emitted noise (EMI) from the supply. This waveshape combines the efficiency of a square wave with the low-noise performance of a sine wave.
4.
Fully Isolated Input-to-Output 100% isolation means that there is no chance of introducing ground loops using the
DSPower! Supply.
5.
Oversized MosFETs. The dual IRLR014 FETs in this design are oversized by a factor of 300%. You can short the outputs all day and nothing will blow up (although it might get hot). The supply is fully protected against reverse voltage, thermal overload and short circuit. A 3A onboard fuse handles extreme overcurrent situations and provides a measure of safety.
6.
Double Sided, Blue Soldermask, Gold Plated PCB. It's PRETTY.
7.
Diagnostic Green LEDs give immediate visual indication that any of the 5 output voltages are functional. They are not blinding, however, and will not leak light outside the chassis.
8.
Mixed SMD and Through Hole design. Maximizes longevity and reliability. Surface Mount (SMD) filter capacitors require additional mechanical fixing (blobs of glue) and are subject to capacity loss during the soldering process. Therefore, the filter capacitors, inductors, transformer and terminal connectors are all through hole mount.
