Description

Module A-160-2 is an enhanced version of the standard clock divider A-160. The module is a frequency divider for clock/trigger/gate signals, designed to be a source of lower frequencies, particularly for rhythm uses. The Clock input will take any digital signal from, eg., an LFO, MIDI sync, or the gate from a MIDI-CV interface. At the outputs, you have access to three sets of seven different sub-divided clock signals, from half the clock frequency down to 1/128. The low/high levels of the output signals are 0V and about +10V.
The A-160-2 also has a reset input. Whenever a reset signal is sensed, all outputs are set to certain levels which depend upon the selected mode.

These are the most important features of the module:

  • Three different sets of dividing factors, selected by a three-position switch at the front panel:

power of two: 2, 4, 8, 16, 32, 64, 128
prime numbers: 2, 3, 5, 7, 11, 13, 17
integer: 2, 3, 4, 5, 6, 7, 8

  • Two output modes, selected by a two-position switch at the front panel:

Gate mode: outputs act like the outputs of typical binary dividers
Trigger mode: in this mode the outputs are AND-wired with the clock signal (i.e. the clock pulsewidth affects the pulsewidth of the outputs)
(the center position labelled “Cst” has no meaning so far, please refer to the note at the bottom of the page)

  • Clock edge type selected by a jumper on the pc board:

positive: the rising edge of the clock signal triggers the state change of the outputs
negative: the falling edge of the clock signal triggers the state change of the outputs

  • Reset behaviour by two jumpers on the pc board:

level triggered: the level at the Reset input triggers the Reset
edge triggered: the edge of the signal at the Reset input triggers the Reset
positive: a high level (> 2.5V) or the rising edge at the Reset input triggers the Reset
negative: a low level (< 1 V) or the falling edge at the Reset input triggers the Reset

  • Output polarity selected by a jumper on the pc board:

positive: non-inverted outputs
negative: all seven outputs are inverted
The sketches show the behaviour of the outputs for the different modes:

 

Width: 4 HP / 20.0 mm
Depth:: 35 mm (measured from the rear side of the front panel)
Current: +50mA (+12V) / -0mA (-12V)
