XAOC Devices Tallin

Dual VCA with overdrive and soft clipping

6 HP Eurorack module

Tallin by Xaoc Devices is a dual voltage-controlled amplifier with overdrive, offering two identical channels with linear and exponential CV response. Each channel has two simultaneous CV inputs, manual gain from -80dB to +18dB, color LED level indicators, soft-clip circuit, and switchable overdrive simulating classic tube amplifier distortion. DC-coupled for both audio and CV use.

Features

• Dual VCA with independent linear/exponential response switching
• Normalled signal path — Channel B input normalled to Channel A
• Mix output combines both channels
• Switchable response curve per channel for versatile dynamics

Controls & Jacks (14)

• A— Main level/gain knob for VCA channel A. Sweeps from minimum to maximum output amplitude.
• B LED— Signal level indicator LED for VCA channel B.
• A LED— Signal level indicator LED for VCA channel A.
• B— Main level/gain knob for VCA channel B. Sweeps from minimum to maximum output amplitude.
• Drive A— Three-position drive switch for VCA A: Symmetric, Linear, or Asymmetric saturation character.
• Drive B— Three-position drive switch for VCA B: Symmetric, Linear, or Asymmetric saturation character.
• EXP B— Exponential CV input for VCA B. Response follows the exponential curve regardless of Drive switch setting.
• EXP A— Exponential CV input for VCA A. Response follows the exponential curve regardless of Drive switch setting.
• IN B— Audio/CV signal input for VCA B. Normalled to IN A when unpatched.
• IN A— Audio/CV signal input for VCA A.
• OUT A— Processed signal output for VCA A.
• OUT B— Processed signal output for VCA B.
• LIN A— Linear CV input for VCA A. Always uses linear response regardless of Drive switch position.
• LIN B— Linear CV input for VCA B. Always uses linear response regardless of Drive switch position.
