A-155

Doepfer A-155

£254.00

Features of the analog rows (knobs):

  • 8 potentiometers (knobs)
  • lower row: Scale (knob), voltage output range 0 ... ~ +6,5V
  • upper row: 1V/2V/4V (octave range switch for exact VCO control), voltage output ranges 0 ...1.0V / 0 ...2.0V / 0 ...4.0V
  • Glide time (knob), same as portamento or slew limiter
  • Glide Control (control input for switching glide on/off)
  • S&H Control (control input for internal S&H, works like A-148)
  • Pre Glide/S&H-Out (analog output before S&H and glide unit, especially required when external audio signals are used as inputs of the lower row)
  • Post Glide/S&H-Out (analog output after S&H and glide unit)
  • lower row: external inputs for the 8 steps (switched jack sockets), control signals or audio signals may be used as inputs (allowed voltage range -5V...+12V), the knobs of the lower row are working in this case as attenuators

Features of the trigger rows (switches):

  • 4 Trigger/Gate tracks with 2 rows of switches
  • toggle switches of 1-0-1 type (with middle position), which can be used to send a trigger/gate to the track above or below or to send no trigger/gate (middle position)
  • 3 trigger rows (i.e. short pulse for each step set, pulse width corresponds to the pulse width of the clock/step input signal)
  • 1 gate row (i.e. a high signal is applied during the length of the step set)

Control inputs and buttons:

  • Step (defines the tempo of the sequence, same as clock or trigger input)
  • Reset (resets all rows to step 1)
  • Start (starts the sequence at the momentary position)
  • Stop (stops the sequence at the momentary position)
