Doepfer - A-151: Quad Sequential Switch

Manufacturer Description: Module a-151 (quad sequential switch) is like an electronic four-position rotary switch.it includes trigger and reset inputs, four in / outputs, and a common out / input. each time a pulse is received at the trigger input socket, the common out / input is connected to the next in / output. after the fourth in / output, the next trigger makes it step back to the first again, and so on. a positive pulse at the reset input switches the out / input immediately back to the first in / output voltages in the range -8v...+8v at the o/i resp. i/o sockets can be processed by the module.four leds indicate the active in / output (ie. the on that is connected to the out / input at any particular time).similar modules: a-152 voltage addressed track&hold / switch (multiplexer) / digital outputs.this module has a maximum current draw of 20ma. it requires 4 te/hp worth of space to fit in a eurorack frame.
