Audio Mixer Project - Introduction

First things first...

I've been a musician basically all of my life. Around 12 years ago I played drums professionally in local bands and managed to do around 500 shows. I also dabbled in guitars & keyboards.

Anyways over the years I've accumulated a ton of semi-pro audio equipment for home recordings etc. but nowadays I just want a good quality, simple, setup for audio playback from my PC.

To cut a long story short, I want to decrease my clutter and replace my old Soundcraft Spirit SX 20 input mixer with a little 2 channel mixer I can have on my desk.


So I plan to document the many steps involved in creating this little mixer. The topics I hope to cover are: 
  • Schematic and PCB designs
  • Determining the required specifications of the mixer
  • Various electronic measurements
  • Case design in Solidworks
  • Parts selection
At the end of the project hopefully I will have documented the design well enough that the reader can make their own version of this little mixer.

I'll also make all the files (CAD, Schematics, Gerber Files etc.) available for download.

Stay tuned.

Audio Mixer - Part 1 - Playing with OP-AMPS

Audio Mixer - Part 1 - Playing with OP-AMPS When I decided to do this mixer project I first started to play around with op-amps. This entry was originally done as a little report for myself on my first experience using an op-amp. So its mainly theory and simulation. In the next entry I'll breadboard up an op-amp circuit using the OPA-2134 that will be used in the mixer circuit. The objective is to demonstrate a straight forward, easy to understand, example of the operation and use of Op Amps in a circuit. The circuit consists of an LM324 Quad Op-Amp, Microphone and a speaker. To get a decent audible level from the selected speaker, a Peak to Peak (PP) voltage of 12V is required. This was calculated by feeding a source signal from a wave generator and adjusting the PP value. Using the oscilloscope it was also determined that the microphone produced a PP value of roughly 20mV. This leads to the following formulas:                  Required Output (Vout) = 12V

Mixer - Part 2 - Using the OPA2134

Hi, This is just a quick post showing my tests of the OPA2134 OPAMP from TI. Datasheet - http://www.ti.com/lit/ds/sbos058a/sbos058a.pdf I'm not sure whether or not I'll use this in the final design but as its touted as a "High Performance Audio Op Amp" I figured it's not a bad place to start. At around $7 AUD its not necessarily the cheapest Op Amp around. It's available in single, dual and quad versions but as I'm after individual control of the Left and Right channels, I chose the 2 channel 2134. Now to the breadboard! If you read the previous entry I explained how to setup a split power rail (and the reasons why you need one) to supply the + & - voltages used by the chip. Whilst not shown in this quick example, I used a TLE2426 rail splitter IC to supply +6V and -6V from a 12V power supply. I'll show the use of this chip in detail in another entry. Rather than go through the theory of the values used I've decided t

Omron CJ1M-CPU11 PLC Teardown

Image
Hi, Recently I asked a lecturer what processor the OMRON PLC's generally used and all I got was a dumbfounded look and a who cares reaction. Fast forward a couple of months I purchased a used one off eBay and to initially program the unit I had to pull it apart. I'll go into more detail about that in another post but I thought why not take some photos and identify the main components on the board. I couldn't find any reference on the net as to what's inside one of these units so I thought some people out there might find it interesting. As expected ,however, there's not much to them. The main chips and their datasheets are: Renesas HD6437145 - Datasheet Cypress - CY7C1021CV33 - Datasheet - $6.94 Maxim – MAX3243 - Datasheet - $7.67 Renesas – R1LV0408CSA - Datasheet - $19.85 SN74LV14A - Datasheet - 72c Thanks for reading Justin
