Use relays to control input channels
hi!
I'm making a gainclone, which only have one input source. I'm thinking about controlling the amplifier with an Arduino (a microcontroller), that can control the heatsink temp, turn fan on or off if necessary. I will also make it compatible with IR remotes. But yes, back to the question. I'm going to make four diffrent audio inputs. one for cd, one for AUX, one for LP and one for Radio. can i use relays for controlling inputs, like my fancy little schematic shows? Will this affect the music quality? LINK TO RELAYS: New 5V 8 Channel Relay Module Board for Arduino Pic AVR MCU DSP Arm Electronic | eBay |
