Antelope Audio DA Distribution Amplifier - Manual (Page 4)

Alternate Sample Rate Selector for Word Clock outputs 7 and 8.
Word clock outputs 7 and 8 are capable of outputting frequencies different from the clock
received by the DA. The first five settings select frequencies that are multiples of the
incoming clock. The final setting, 256 WC, configures the corresponding output to generate
256 FS Clock (sometimes referred to as Superclock), a protocol used by some Digidesign
components.
A red LED is present above each knob. When lit, it indicates that a valid sample rate is
selected. When flashing, the output has been configured to output at a frequency outside
the supported range (32kHz- 192 kHz).
For easy reference, the following chart indicates what frequencies outputs 7 and/or 8
transmit depending on incoming sample rate and knob settings. Although the DA can
receive any frequency between 30kHz and 202 kHz, this chart is limited to those most
commonly used.
