Doepfer A-131 VCA, Exponential

Details
The Doepfer A-131 VCA is an Exponential voltage-controlled amplifier. Exponential VCAs are often associated with audio signals, but it doesn't always have to be that way. Equipped with two audio inputs, each with its own attenuator, the A-131 amplifies the signals by an amount determined by the combination of the gain and the two CV controls. The module uses a high-end VCA circuit that is able to process slowly varying CVs as they have DC coupled signal inputs/outputs. The A-131 delivers high quality, powerful voltage-controlled amplification in a simplistic and intuitive format.

Pay by Finance

To make it as easy as possible for you to get the gear you want, we offer a range of instant finance options. If you spend £250 or more online, you can choose to pay over 48, 36 or 24 months. The majority of decisions are given instantly, so you could get your new gear sooner than you thought!

Representative Example

To help you understand how our finance options work, the examples below are based on a total order value of £250:

Finance APR Deposit to Pay Payments Total Payable
Classic Credit 48 Months 14.9% 14.9% No Deposit 48 months: £6.83
Final payment: £6.83

How to Apply

Applying for finance couldn't be easier - if your order totals £250 or more, simply proceed through the checkout as normal, then select Pay by Finance on the payment page, then click the orange APPLY FOR INSTANT FINANCE button. This will start your application with V12 Retail Finance, our finance partner, and completing this form should take approximately 10 minutes.

You should get an instant answer on whether your application has been successful, though in some rare cases V12 may need to look at the application in more detail.

Specifications

  • Width: 8HP / 40.3mm
  • Depth: 45mm (Measured from the rear side of the front panel)
  • Current:
    • +12V: +20mA
    • -12V: -10mA

Controls & Indicators

  • The A-131 features an exponential (AKA logarithmic) response. That means that CV changes have less effect at low levels of amplification that at high levels, and makes the A-131 more sensitive and suitable for subtle changes at low levels
  • Gain: Controls the overall gain of the VCA. At 0, with no CV present, there is no amplification at all, meaning there will be no signal at the output of the VCA. One the gain is increased, amplification will occur, even if there is no CV input preset. The gain control shifts the entire VCA response upwards
  • CV 2: Attenuator that affects the level of voltage control at the CV 2 input. It controls the amount of effect the CV has on the VCA's amplification
  • IN 1: Attenuator for controlling the level of the signal patched into Audio In 1
  • IN 2: Attenuator for controlling the level of the signal patched into Audio In 2
  • Out: Attenuator that controls the total volume of the VCA's output

Inputs & Outputs

  • CV 1: Control voltage input. The voltage at this input is combined with the voltage at CV 2. The effective range of the VCA goes from 0V (no amplification) to +5V (maximum amplification)
  • CV 2: Control voltage input. The voltage at this input is combined with the voltage at CV 1. The effective range of the VCA goes from 0V (no amplification) to +5V (maximum amplification)
  • Audio In 1: Input for the signal you wish to amplify
  • Audio In 2: Input for the signal you wish to amplify
  • Audio Out: Output for the amplified signal
