ALM Busy Circuits Beasts Chalkboard (ALM002)

Beast’s Chalkboard is dual channel stepped voltage source and adder for your eurorack modular synthesizer system. It can also function as a dual precision buffered mult. 

It primarily is intended as a dual octave switcher for VCO’s but has many other uses including sequence transposition, FM ratio creation, buffered CV distribution and VCO calibration.

Key Features:

• Dual channel voltage adder and source with 1V stepped range of -2 to +2 volts (i.e 5 Octaves)
• Two Buffered outputs and through output per channel
• Top input normalized to bottom. Allows input to be varied across both channel outputs
• Bottom octave switcher can be chained to top extending range to 9 octaves
• Also functions as 1->6 or dual 1->3 buffered mult.
• Skiff friendly
• Designed and built in England.
• An ALM Classic.

Technical Specifications:

• Supply: +12V ~25mA / -12V ~25mA
• Size: 6HP
• Depth: 22mm (including power header)
• Offset Error: +/- 10mV
