Word Clock Input: BNC connector takes a TTL level signal at the sample rate to sync the
A\D to the external sample rate. HEDD will sync from 20 kHz to 192K
kHz. The input impedance is 75 ohms.
Word Clock Output: BNC connector this is a TTL level square wave that can be used to
provide sync to other equipment. The WC output will be the selected
sample rate or the rate of the WC input.
Internal Sample
Rate: 44.1kHz TO 96kHz determined by front panel switch.
