400ADA-AUD

Analog Audio Distribution Amplifier

The 400ADA-AUD Analog Audio Distribution Amplifier is a general-purpose 1x9 amplifier for distributing balanced analog audio signals.

The 400ADA-AUD can be operated with either differential or single ended inputs and offers a wide range of gain adjustment to handle a wide variety of input signals.

The 400ADA-AUD is housed in the 3RU exponent 400FR frame that will hold up to 16 modules.

Features
  • Differential and single ended input (automatic single ended to differential conversion)
  • High impedance inputs
  • Low impedance inputs
  • Wide gain adjustment range
  • High common mode range and common mode rejection ratio
    • Very high SNR
    • Very low THD+N
    • Card Edge LEDs
    • Module status / Local fault
    • Power supply status
