Ideal for experimental musicians and sound designers who want a flexible and affordable interface.

Product Description

Doepfer A-119, External Input / Envelope Follower

Module A-119 is used to integrate external audio signals into the system A-100, and includes the components pre-amplifiers, envelope follower and a comparator. The preamplifier has two inputs: the unbalanced input with a gain factor of 0 ... 20 is mainly used for line-level signals, while the balanced input has a gain factor of 0 ... 500 for the integration of low-level signals (microphone , Electric guitar).

The envelope follower generates an envelope at its output, corresponding to the signal profile of the external audio signal. The comparator generates a gate signal corresponding to the level of an adjustable trigger threshold. Three LEDs are used to control the amplification (overdrive), the envelope and the gate signal., Width: 8HP / 40.3 mm, Depth: 45 mm (measured from the rear of the front plate), Power requirements: 30 mA (12 V) / -20 mA (-12V)

PROS
  • • Excellent pre-amp gain range for both line and mic signals
  • • Envelope follower accurately tracks complex audio dynamics
  • • Balanced input handles low-level signals with impressive clarity
  • • Compact HP width maximizes space in dense modular setups
CONS
  • • Limited routing options compared to more advanced envelope processors
  • • Gain staging can be tricky, requiring careful adjustment
  • • The comparator’s trigger threshold isn’t as precise as dedicated gates

Frequently Asked Questions

Absolutely, the comparator output provides a gate signal that can trigger percussion or other rhythmic events based on vocal dynamics.
Yes, the 500 gain factor provides enough headroom to handle a dynamic microphone’s output level without excessive noise.
It's fairly standard; not as snappy as some dedicated envelope generators, but versatile enough for most applications.
