Hi, does anyone out there know of any schematics for building a mixer with two input channels? In addition, the signals being input can be modulated such that the output can have a echo effect. Thanks in advance.

In >addition, the signals being input can be modulated such that the output can have a echo effect. Craig Anderton has written two books that have schematics for just exactly this sort of thing. The titles are something like "Electronics Projects for Musicians" and "Home Recording for Musicians". Ask at your local guitar shop or write to the Mix Bookshelf for a catalog (you can find the address for Mix in most any Electronic Musician magazine.) ron@vicorp.com

Here's a simple 2 channel audio mixer: R C +------/\/\/\/\---+ || R | | V1 --||---/\/\/\/\----------+ | |\ Vcc | || | | | \ | | +--+----|- \| | C | | \ | || R | | \ | V2 --||---/\/\/\/\----------+ | \______|_______ Vo = -(V1+V2) || | / | / | / +----|+ /| | | / | | |/ Vee GND The values of the components can be R= 47k ( good choice for audio applications ) C= 0.1uF Vcc= -Vee= 9 V. Op Amp 741 for low to medium performance audio applications. Any other low noise type can be used for higher performance/fidelity. <Ayman> -- [ Ayman Issam Kayssi | Email: ] [ Advanced Computer Architecture Lab. | ayman@caen.engin.umich.edu ] [ EECS Dept., Univ. of Michigan, Ann Arbor | ayman@eecs.umich.edu ]
