Sample Rate 
 
The sample rate for your AudioFire hardware is set here.  The sample rate, also 
known as clock rate, affects recording and playback. For more information please 
refer to Appendix C: An Introduction to Digital Recording.  The application or 
audio software you are using may change the sample rate.  The settings tab gives 
you an easy way to see exactly what sample rate your audio is set to. 
 
The “Locked” setting allows you to lock the sample rate.  If you want to always 
run at a particular sample rate and block software from changing the sample rate, 
select the “Locked” setting. 
 
Clock Source 
 
 
Under clock source you may select the input clock source.  The clock source 
setting is used to synchronize your AudioFire hardware to another piece of audio 
hardware. If a given synchronization source (input clock) is not detected, that clock 
source will be grayed out.  You will only be allowed to select input clocks that are 
currently connected.  For more information please refer to “Synchronizing 
Multiple Devices” later in this manual. 
 
If an external clock is selected and that clock is disconnected, the button will turn 
red. You will either need to reconnect the clock source or select the internal clock 
button.
 
 
S/PDIF Format
 
 
AudioFire2, AudioFire4 and AudioFire8 can transmit digital information in two 
formats: “professional” or “consumer.” The primary difference between the two is 
in the implementation of the SCMS copy protection bit, which, in the Consumer 
format, prevents the user from making digital copies of a digital copy.
