Doepfer A-160-2 Clock Divider 2. - Standard

You are looking at the Doepfer A-160-2 Clock Divider 2 - Standard Color.

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, e.g., 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:

o power of two: 2, 4, 8, 16, 32, 64, 128

o prime numbers: 2, 3, 5, 7, 11, 13, 17

o integer: 2, 3, 4, 5, 6, 7, 8

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

o Gate mode: outputs act like the outputs of typical binary dividers.

o 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)

o (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:

o positive: the rising edge of the clock signal triggers the state change of the outputs.

o negative: the falling edge of the clock signal triggers the state change of the outputs.

· Reset behavior by two jumpers on the pc board:

o level triggered: the level at the Reset input triggers the Rese

to edge triggered: the edge of the signal at the Reset input triggers the Reset

o positive: a high level (> 2.5V) or the rising edge at the Reset input triggers the Reset

o 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:

o positive: non-inverted outputs

o negative: all seven outputs are inverted
