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 400FR frame that will hold up to 16 modules.
