400ADA-AUD

Analog Audio Distribution Amplifier

Interact with this product in a Layout Tool:

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.

特点

  • 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
