This 12HP module is a re-imagining of the voltage controlled amplifier from the ARP 4019 module of 1971. The discrete transistor VCA has a distinctive warm tone.

DESCRIPTION The AM1019 has been carefully engineered to be the ultimate replication of the original voltage controlled amplifier:

  

• Large number of inputs (3x audio, 4x CV), to mirror the matrix switch capability
• 5% carbon resistors in all CV and audio inputs
• Three audio inouts, one of which is inverted
• LED illuminted push buttons for AC blocking on audio inputs
• Linear and exponential CV inputs operate in parallel
• ARP 2500 control knobs with coloured spun aluminium inlays (Rogan RB-67)
• Black and silver phenolic control knob for VCA gain control
• Bourns PTL20 LED slide pots with subtle amber LED;s
• Subtle pink LED for volume level

  

The AM1019 creates beautiful warm sounds from the vintage VCA and has an amazing new aluminum printed front panel design. Operating as an audio VCA with the blocking capacitors engaged, or for CV signal manipulation with the blocking capacitors removed.

  

CONNECTIONS There are  seven 3.5 mm jack sockets on the anodised aluminium front panel:

  

• IN 1, 2 & 3 - audio signal inputs with individual level controls
  
• CV 1 and C2 - control voltages inputs for linear amplitude contol (with attenuation)
• CV 3 - control voltage input for exponential amplitude control (with attentuator)
• CV4 - control voltage inputs for exponential amplitude control
• OUTPUT - audio signal output with LED indicator

There are high quality Alpha rotary potentiometers for adjusting amplifier gain, and the three signal input levels, along with Bourns LED slide potentiometers for amplitude control from CV 1, CV2 and CV3 inputs.

The module comes with a set of M3 mounting screws and washers, and a standard 10 to 16-way Doepfer power cable. Module depth is 26mm.
