The source input, marked as Sonos in the diagram below (this is almost always the source of music in my house these days) can be taken from RCA connection of the Sonos or using a split cable take one into this unit and the other to the amplifier. The amplifier output should be connected to an output of the amplifier, connection to tape recorder is typically not used anymore these days and can very well be the best place to connect this unit to your amplifier (recording output of tape from Amplifier to the Amplifier jack of this unit). I used 220 Ohm as I placed the IR LED very close to the amplifier IR sensor. Do not go below 100 ohm otherwise you might fry your Arduino. 1.2M views 5 years ago Home Audio Basics How do you connect a speaker to an amplifier I got this question a while back and its time to give the most thorough answer possible Check out. Note that if you do that, the resistors should be slightly different between the Red, Green and Blue ones (for example 330 for Red, 300 for Green and 270 for Blue for the RGB LED that I have).ģ) Reducing the value of the resistor of the IR LED can increase the distance between the IR LED and the amplifier under control. If you want to play around with different colors and stuff, you will need to move to three different resistors one for every color. I use only one resistor and that means that you can only have one color at a time from this RGB LED. If showing Blue, that means amplifier is ON and music is played by source.Ģ) Increasing the value of the resistor of the status LED will make it dimmed which might be desired. Well use two amp channels to power the left and right speakers. If showing Green, that means amplifier is ON but no music is played by source Zone 2 is simple, with just one pair of speakers in the basement den. If showing Red, that means amplifier is off and no music is played by source. The circuit here is a subset of it and for it no PCB is really necessary (but since I got 10 PCBs in a batch. The PCB shown in the picture is part of a shield designed for similar idea that also includes Equalizer bar-graph of the music.

The best place to learn the codes of your gear is by looking at You will need to change one or two hex codes only in the KenwoodIdle.PDE file. Changing the program to work with another set of codes is really simple.

The code here is set to work with a Kenwood 6030 amplifier. If source is playing then the unit will turn amplifier on by using the sending the remote infrared code to turn it on, and when idle for some time, the unit will send the power off remote infrared code to turn off the amplifier. It is pretty similar to another project I posted a while ago, but here it turns amplifier on and off. Do you have an amplifier hidden somewhere in the living room or basement (or home theater) that you want it to turn on when you start to play music? This circuit is the solution for you!
