Malcolm Toft MICMIX

Because of the wide amount of connectivity and versatile signal routing provided, it soon becomes apparent that it's small size belies the flexibility of operation that is possible. Two of its immediately obvious applications are that of a multi track 'front end' for recording to a DAW via multi channel A to D converters and as a summing mixer to provide analogue 'warmth' during the mix process. The setup for these are shown on the pages of this manual entitled 'Multi Track Recording' and Stereo Recording'.

It should be noted that whilst being designed to provide a high input impedance for use with musical instruments such as guitars, the instrument inputs are of very high quality and can easily be used as a line level input, again increasing the versatility of the unit.

It goes without saying that as a product designed by Malcolm Toft it brings with it his more than fifty years designing recording consoles and associated equipment that is used in the very best recording studios around the world. The microphone amplifier is a precision instrumentation amplifier providing a frequency response in excess of 40kHz with low noise and very low distortion. A custom designed microphone level control avoids the 'cramping' often found in microphone amplifiers with a wide range of gain controlled by a single potentiometer.

The instrument input uses a jfet amplifier that provides an input impedance suitable for just about any guitar input and again offers an extremely smooth frequency response with low noise and distortion.

All balanced outputs are ground compensated so that if the negative output is grounded making the output unbalanced, the gain is compensated to allow for the signal loss.
The unit is self powered by a.c. mains operating fron 80-250v.
