This section describes the basic operation of your 9301 product.
Figure 1. Simplified Block Diagram of 9301 Functions
AES signals are received on the input BNCs. AES audio is sample rate converted to match the selected
clock source. AES routing, gain, and polarity are then applied. The signals are then stored in memory,
providing an audio delay of up to 5.461 milliseconds.
