Micro Processor controlled Stereo Pre Amplifier

The stereo pre amp is made up from several modules all designed by me namely - ATmega32 micro controller with OLED display, rotary encoder and IR receiver for Apple remote, - the PGA audio controller, - an OPA2314 based phono pre amp, - audio input selector with optical relays, and a low noise 5V/2A and +-5V/150mA power supply. The ATmega evaluates the user commands from the IR remote and the encoder, updates the oLED and handles the PGA2311 audio gain controller and the 5 input channels. All boards have been manufactured by PCBway based on my Target3001 layouts. Processing time and delivery to Germany of the orders was between 5 and 7 working days. All boards are in excellent quality. I was very impressed by the quality and the professional ordering process. Unmatched service regarding quality, processing time and price!
