The 400DA2Q-AESB provides an economical method of distribution for your 110Ω balanced AES digital audio signals. The DAs feature two auto-equalized inputs with four reclocked outputs each. The module can also be configured for one input with eight reclocked outputs for applications where a larger number of outputs are required.

The 400DA2Q-AESB is housed in the 400FR Exponent frame that will hold up to 16 modules. The 400DA2Q-AESB card edge LED indicators provide quick and accurate assessment of the incoming signal integrity.
