3 Channel Audio Mixer Circuit
Although the modular Portable Mixer architecture accessible on these web pages has become a hit for abounding amateurs, some correspondents appropriate a abundant simpler device, mainly for bond address signals.
This architecture should fulfil their needs, featuring three inputs with switchable high/low acuteness and abnormal level-control circuits, accouterment aerial afflict margins and low-noise figures, proportional to gain-level settings. Low accepted burning due to a simple, five-transistor circuitry, allows the Mini Mixer to be powered by a accepted 9V PP3 array for abounding hours.
