Uneeda Audio - Universal Pad PCB Kit

The universal pad board provides a simple and convenient way to make and use single-value attenuator pads. The board accomodates most of the common fixed attenuator topologies: H, T, L, U, O, Pi, Bridged Tee. The wiring layout is flexible enough to be used with either balanced or unbalanced configurations.

The board is small: 2.062 x 0.85 inches. It does not fit inside an XLR tube. There is a hole provided for a single swage spacer (supplied). You can purchase the board several different ways. Click here for the Universal Pad Board manual.

One Small Detail

If you are ordering a complete kit, with resistors, delivery could take at least two weeks, possibly more. Why? Because if I don't have the resistors on hand, I have to order them. Think about the problem:

1% resistors use the e-96 series of perferred numbers for their values. This means that there are 96 values for every decade. There are 5 decades between 10-ohms and 1-Megaohm. To have every e-96 value between 10-ohms and 10-Meg is 480 resistors. That's a lot of resistors.

I stock many of the e-96 values, and I stock all of the e-24 (5%) values. If you request a value that I don't have, I'll have to order it, which takes time. There's no way to forsee which values I have and which ones I don't. I charge a small premium for this service. I'm willing to buy 100 at a time. Are you?

Resistor Choice

I'm into buying good parts, but I refuse to buy pedigreed parts. If that's your game, be my guest, but don't ask me to be your purchasing agent. My 5% parts are all carbon film resistors, with varying sources, mostly Asian.

My 1% parts are a mix of US and Asian parts. Some are Vishay Dale, but newer parts are made by Koa-Speer.

Design Service

If you can't make heads or tails out of the calculations, I'll do them for you... For a Price. Design time is $75 per hour. Most designs take 15-minutes. The design process is supposed to be simple, so this should be a learning experience for you. Whatever... Send me your problem, and its application, and I'll tell you how many 15-minute blocks this represents.
