Bastl Instruments - ABC (six ch. mixer)

ABC is a simple 6 channel signal mixer. It has 6 inputs – A, B, C, D, E, and F – and two outputs – A+B+C – which is mixed into the D+E+F output if nothing is inserted in the A+B+C jack. ABC is designed to mix audio signals but can be modified to mix CV signals instead. There are 6 solder jumpers on the backside, which can be connected to turn the ABC mix into a CV mixer.

Simple yet versatile: ABC mixes mono, stereo, or CV signals

There are also 3 jumpers on the backside 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 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
• 35 mm deep (skiff friendly)
• current: +12 <10mA, -12 <10mA
