Doepfer A-160-2 Clock Divider

Name: A-160-2 Clock Divider
Brand: Doepfer

Binary and prime clock division for polyrhythmic complexity

4 HP Eurorack module

The A-160-2 is a clock divider module that takes an incoming clock or trigger signal and outputs divided sub-frequencies from /2 to /128, with selectable binary or prime number division ratios. Its ability to generate polyrhythmic and polymeter patterns from a single clock source gives it a distinctly generative and rhythmically complex musical character.

Features

Clock division from /2 to /128 in binary mode
Prime number division mode with ratios /2, /3, /5, /7, /11, /13, /17
Selectable trigger pulse or constant gate output mode
Seven simultaneous division outputs available at once
Individual LEDs for each division output
Reset input via CI jack for synchronization
Improved version of the original A-160 with two additional mode switches
Zero negative rail current draw
