When you split a signal twelve ways, physics works against you. A standard passive splitter divides the electrical energy of the source signal, leading to:
The noise floor increases by approximately 3dB for every two stages engaged in THRU mode due to cascade noise accumulation. This is a known design limitation—Visual Audio prioritized the “analog warmth” of cascaded discrete transistors over low noise. visual audio splitter amp- joiner 12 serial
Long cable runs act like antennas, picking up electromagnetic interference. When you split a signal twelve ways, physics
