Toppobrillo - Mixiplexer
1-4 & 4-1 Panner | Scanner
The Toppobrillo Mixiplexer or "mixing multiplexer", is a unique hybrid signal routing device that marries the idea and design of a quad-panner with a 4-channel crossfader, otherwise known as an "interpolating scanner". It is a flexible 4-to-1 and/or 1-to-4 voltage-controllable "switch" with an adjustable linear cross-fade between channels. possible applications include source location or "position" control in a multi-channel setup, timbre mixing or "morphing" between sources, "soft" (ie. pop-free) switching, nonlinear wave-shaping techniques, and programming.
The Mixiplexer is all analog, and has been designed with audio in mind-(though is DC coupled) employing high quality low-noise VCAs throughout, with excellent channel separation and gain matching from channel to channel. "off" is really "off" (-100dB) and "on" is never greater than unity gain. Many combinations of input/output routing are possible.
