So let’s say you have an RG-59 cable or something similar. It’s several hundred feet long but it developed a break somewhere along it’s length. The problem is it’s not obvious where the break is. Now what do you do? Option 1: Cut the cable in half, check each half …
Every sound/recording engineer is familiar with the terms unbalanced and balanced interfaces… more commonly referred to as “unbalanced or balanced lines.” Yes, everybody knows “unbalanced line” can be very susceptible to noise (for very long runs), and that “balanced lines” are more preferred because they’re quieter, i.e. not as susceptible …
CircuitLab.com is a cool web-based “workbench” where you can create circuits and simulate it. You can do DC analysis, Time Domain, Frequency Domain analysis. I think it’s a great learning tool to “experiment” with circuits and see what will happen. No special software need to be installed, you can run …
Our stock SK-1DI Mic Preamp uses a potentiometer for the gain control. It’s simple, it works, you turn the pot and you control the gain. But some users may prefer a stepped switch instead of a potentiometer, so they can precisely control the gain. It also makes “recall” easier as …
I’ve been trying to optimize performance of my new upcoming Mic Preamp Kit, the NK-72DI. It’s hooked up on my workbench to various probes and meters, and displays. I want to make sure that performance of this new Mic Preamp will be top-notch, and something my customers will be proud …
Just testing some PEQ-503 EQs before shipping out to customers. Each frequency band has two (2) selectable frequencies, and a bypass switch. It also has an overall EQ In/Bypass switch to let you easily make before & after sound comparisons. The equalizer’s smooth broad curves makes tonal adjustments easy and …
Hello folks! I’m currently working and testing a new mic preamp kit as successor to our SK-1DI 500 Series Mic Preamp Kit. I’m calling it our NK-72DI. This new mic preamp will feature Carnhill transformers, imported from the UK – the same kind of transformers used in Neve preamps and …
An opamp doesn’t know where the “Ground” is, so one can normally operate an opamp from a dual power supply (i.e. also called split power supply, dual power supply with +/-V supply voltages) or from single-supply voltages (V+ & Gnd). As long as you don’t exceed the Maximum Ratings specified …
So here’s the scenario… you have a power transformer with a voltage output of 25V + 25V AC. Let’s say, you’re using this power transformer to supply power to a power amplifier project. So it’s all good. But you also need 5 Volts DC to power some logic circuits (a …

Back in October 1st, we released our SK-1DI Mic Preamp Kit for the 500 Series API format. I’m happy to announce that Rev.1.2 PCB is now out, incorporating fixes and suggestions from our customers and fixing a …
