APPLICATIONS
device to the first SMUX source device via BNC, and to sync the first SMUX source device 
to the DigiMax FS via BNC (or optical) and designate the DigiMax FS as word clock master. 
A third way would be to set all three devices to external word clock via BNC and to use a 
master word clock generator and distribution amplifier. 
ADAT Optical light pipe
ADAT is an optical format that supports eight channels of digital audio over optical light pipe. 
Suported sample rates are 44.1 and 48k. 
 A set up where you are utilizing eight DigiMax FS preamplifiers and converting to digital 
optical output at 44.1 or 96K sample rate, connect one optical cable from the optical output 
labled 1-8 on the DigiMax FS to the ADAT optical input on your digital audio workstation or 
digital mixer. Press the ADAT sync button on the front panel of the DigiMax FS and set your 
digital audio workstation to sync via optical. 
To synchronize the DigiMax FS via traditional ADAT light pipe, you will need to run only one 
optical cable from the device with the ADAT clock source to the optical input #1 of your 
Digimax FS. From the front panel, select ADAT for your external clock source. The 
Digimax FS will sync to the word clock within the optical signal coming into it’s first optical 
input. To sync another device from the DigiMax FS via light pipe, simply run one optical 
cable from the DigiMax FS to the device you wish to connect and set the other device to 
receive External Clock from it’s optical inputs. You can do this whether the DigiMax FS is 
set as a word clock master or slave.
