Conventional digitally controlled volume schemes usually fall into three categories:
- Potentiometer + Stepper Motor – Simple and easy to control, but prone to left–right channel imbalance and limited separation.
- Relay Array – Preserves signal integrity, but frequent relay switching produces audible clicks and high-frequency noise.
- Electronic Volume Chips – Inexpensive and simple, but their integrated resistors lack the quality of discrete precision parts, introducing coloration.
NADAC L rejects these compromises. Instead, it is built around a full analog signal path, ensuring high precision, ultra-low noise, and uncompromised signal integrity
