  • Four-Channel Mixer With Logarithmic Potentiometers
  • Logarithmic Pot Response Especially Suited For Audio Signal Mixing
  • Each Channel Equipped WIth Its Own Attenuation Control
  • Master Attenuator For Controlling The Output
  • Ideal For Use At End Of Signal Chain To Interface With Other Devices

Doepfer A-138bV Mixer, Logarithmic, Vintage Edition

Details
The Doepfer A-138bV Mixer is a powerful four-channel mixer, ideal for mixing either audio or CV signals. Each input/channel is equipped with an attenuator, on top of the module's master attenuator. The A-138bV features potentiometers that have a logarithmic response, making it much more suited to the mixing of audio signals. The Doepfer A-138bV is perfect for placing at the end of your audio chain, and can even be used to directly interface with an external device such as an amplifier or mixer.

The A-138bV is the Vintage Edition of the powerful A-138 Mixer, featuring a striking vintage finish.

Logarithmic Potentiometers For Audio Mixing

The Doepfer A-138b is equipped with potentiometers featuring a logarithmic response. This makes them especially suited to mixing audio signals. You can patch your audio signals into inputs 1 to 4, and adjust the relative amount of each signal with the input's respective controls. The entire mixed signal is output through the Out socket.

Input 1 Offset Function

On the Doepfer A-138b's PCB you can find a pin header labelled JP4. This can be used to enable voltage offset for Input 1. By placing a jumper onto JP4 in the right position (towards the edge of the PCB), a positive offset voltage is generated by the In 1 control, providing that nothing is inserted into Input 1. If a jumper is put to JP4 in the left position (direction to the front panel), then a negative offset voltage is generated.

Specifications

  • Width: 8HP / 40.3mm
  • Depth: 35mm (Measured from the rear side of the front panel)
  • Current:
    • +12V: +10mA
    • -12V: -10mA

Controls

  • In 1: Attenuator for controlling the level for Input 1
  • In 2: Attenuator for controlling the level for Input 2
  • In 3: Attenuator for controlling the level for Input 3
  • In 4: Attenuator for controlling the level for Input 4
  • Out: Master attenuator for determining the output level of the mixer. This allows the module to act as the end of the audio chain and interface directly with devices such as amplifiers or mixing desks

Inputs/Outputs

  • Input 1: Audio/CV input, channel 1
  • Input 2: Audio/CV input, channel 2
  • Input 3: Audio/CV input, channel 3
  • Input 4: Audio/CV input, channel 4
  • Output: Output for the complete mixed signal
