Bastl Instruments ABC

ABC is a relatively simple 6 channel signal mixer. It has 6 inputs – A,B,C,D,E, and F – and two outputs. The A+B+C output is mixed in to the D+E+F output if nothing is inserted in the A+B+C jack.

The ABC mixer is designed to mix audio signals, but can be modified to mix CV signals instead. There are 6 solder jumpers on the back side, which can be connected to turn the ABC mix into a CV mixer.

INPUT NORMALIZATION

There are also 3 jumpers on the back side which can be used to normalize inputs A to D, B to E and C to F. This is useful if you would like to use the ABC mix as a 3 channel stereo mixer (using both outputs and having separate volume control for the left and right channel).

FEATURES

• 6 channel mixer
• 6 inputs A,B,C,D,E,F
• 2 outputs: A+B+C and D+E+F (A+B+C is mixed into D+E+F if no jack is inserted in A+B+C)
• 3 jumpers to select normalization of inputs A to D, B to E, C to F (useful for stereo mixing)
• inputs are AC coupled
• there are solder jumpers for changing the inputs to DC coupling (then it can be used for mixing CV signals)

TECHNICAL DETAILS

• 5HP
• 35mm deep (skiff friendly)
• current: +12 <10mA, -12 <10mA
• PTC fuse and diode protected 10 pin power connector
