Essentially it's the same basic circuit as the A-111-2 but with reduced features:\u003cbr\u003e\u003cbr\u003e triangle core\u003cbr\u003e fully analog design\u003cbr\u003e\u003cbr\u003e min. 15 octaves pitch range in each mode (VCO\/LFO):\u003cbr\u003e VCO mode: typ. 0.5 Hz - 20 kHz (with appropriate external CV)\u003cbr\u003e LFO mode: typ. 0.001 Hz - 40 Hz (with appropriate external CV)\u003cbr\u003e\u003cbr\u003e range switch so that the module can be used as VCO or LFO (in LFO mode all frequencies about 1\/500 compared to VCO mode)\u003cbr\u003e about 24 octaves total in both modes (typ. 0.001 Hz - 20kHz)\u003cbr\u003e perfect 1V\/octave tracking over min. 10 octaves (typ. 16Hz - 16kHz in VCO mode)\u003cbr\u003e\u003cbr\u003e exponential frequency section:\u003cbr\u003e Tune control\u003cbr\u003e selectable tune control range by means of an internal jumper: about 0.5 \/ 2 \/ 10 octaves\u003cbr\u003e manual VCO tune range (with jumper pos. 1, without external CV): about 16 Hz- 20kHz\u003cbr\u003e manual VCO tune range (with jumper pos. 2, without external CV): about 16 Hz- 70Hz\u003cbr\u003e manual VCO tune range (without jumper, without external CV): about 16 Hz- 22Hz\u003cbr\u003e if desired the min. frequency can be adjusted by the user (frequency offset trimming potentiometer)\u003cbr\u003e the corresponding frequencies in LFO mode are about 1\/500 lower, the max. frequency in LFO mode is about 40Hz\u003cbr\u003e 1V\/octave CV input \"1V\"\u003cbr\u003e exponential frequency modulation XM input with attenuator\u003cbr\u003e the XM input socket is normalled to a small positive voltage so that the XM control works as fine tune control when exponential FM is not in use. As a logarithmic potentiometer for finer resolution in the lower range is used, also the fine control is exponential \u003cbr\u003e (thank's to Václav of Bastl Instruments for this tip at Superbooth in Berlin)\u003cbr\u003e access to internal bus CV (via jumper, optional, please remove the bus jumper if this feature is not used to avoid unwanted frequency modulation as then the unused CV line of the bus works as a kind of antenna)\u003cbr\u003e\u003cbr\u003e linear frequency section:\u003cbr\u003e linear frequency modulation input LM (without attenuator), DC coupled\u003cbr\u003e Pulsewidth section for rectangle output:\u003cbr\u003e Manual pulsewidth control PW, adjusts pulsewidth from 0% (output = fixed at \"low\" state) up to 100% (output fixed at \"high\" state)\u003cbr\u003e Pulsewidth modulation input PM (without attenuator), about 5Vpp required for full PW range Sync input SY (selectable hard or soft sync via internal jumper)\u003cbr\u003e\u003cbr\u003e Waveform outputs:\u003cbr\u003e Sawtooth, rising edge, output level ~ 10Vpp (voltage range 0 ... +10V)\u003cbr\u003e Rectangle (controlled from pulsewidth section), output level ~ 10Vpp (voltage range 0 ... +10V)\u003cbr\u003e Triangle, output level ~ 10Vpp (voltage range -5V ... +5V, DC offset can be adjusted also also to 0 ... +10V)\u003cbr\u003e Nearly \"perfect\" waveforms (no glitches)\u003cbr\u003e LED (for display in LFO mode)\u003cbr\u003e only 4HP panel\u003c\/p\u003e","brand":"Doepfer","offers":[{"title":"Default Title","offer_id":8884422770735,"sku":"","price":219.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0020\/5199\/7743\/products\/A111-3.jpg?v=1536163220","url":"https:\/\/www.noisebug.live\/products\/a-111-3v","provider":"Noisebug","version":"1.0","type":"link"}
