Looking for an experienced engineer to discuss design of a stereo audio amplifier with wifi as well as a decent active crossover for the already defined drivers. I posses a base knowledge of system level audio amp design, but lack circuit/PCB level skill set. Parameters (can be changed if needed): - Power from a 24V 4A transformer to feed the circuit. - Power Supply Circuit (~200W) - Wifi Audio Circuit (discussion will be needed) - Two Biamplifed Active Crossover Circuits -- (trying to emulate: [login to view URL]) - Pre-Amp Circuit (possibly) - Power Switch - Pre-Amp Input - RCA Input - RCA Output (line level) - Aux Input - Input Switch - Gain - Low-pass/high-pass gain - Left Output Woofer (4 ohms, 20V RMS,40 Max) - Right Output Woofer (4 ohms, 20V RMS,40 Max) - Left Output Tweeter (6 ohms, 15V RMS) - Right Output Tweeter (6 ohms, 15V RMS) Very new to audio over wifi so will need direction as to how to go about the design. I will simply need a circuit sketched up with requirements and part suggestions. I will work on sourcing PCB's and parts (unless this can be done seamlessly). Looking forward to hearing suggestions! Cheers.

Please take a look at my profile. You will find there almost everything you are asking for, schematic as well as routed PCB's both for your amp and a crossover. If it looks like what you fancy, shoot me a message. Thanks, Brian.

Hello, I developed sound amplifiers of different classes. With vacuum tube, transistors, and cheaper analogs. my skype ivanchuba

I've done it all before - even the WiFi. Modules are the way to go for prototype. I would like to clarify how you want the WiFi (or Bluetooth) part to work -- as a transmitter or receiver?

Hi, Regarding your project, there are WiFi microcontrollers with I2S output can can be hooked up to a DAC but few more details about the audio over WiFi would be useful. Do you intent to have a dedicated application running on the system( Windows,Linux, Android etc) that connects to board and streams audio or to have something like an audio device that you can select(like switching sound cards) and any application can use that? If it's the latter then probably bluetooth would be a better choice. Some further details would be needed for the power amplifier section (integrated, discrete, what class?). You can check my portfolio, I have some of my audio related projects listed there, including active crossover filters using JFETs. Best regards, Daniel
