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) 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: The document A160_2_jumpers.pdf shows the position and the function of the jumpers in question. Note: In the final version of the module the upper toggle switch (i.e. the switch which is used to select between Gate and Trigger outputs) is also a 3-position switch. The center position is labelled "Cst" as an abbreviation for "Custom" mode. So far the custom mode is not yet implemented. For future firmware versions a custom mode is planned that can be selected by means of two unused jumpers (probably inverted gate output mode or inverted trigger output mode). Note: It is not possible to connect the A-161 to the A-160-2 as the conception of the A-160-2 is totally different compared to the A-160 with it's fixed binary dividing.
