ProFire 2626
Sample Rate
 
 This menu selects the sample rate of the 
interface when operating in Standalone Mode 
Optical Port B Mode
 
 This parameter determines how the second pair 
of optical ports will operate when the interface is 
in Standalone mode 
 
 
ADAT:
 
 
 Selecting “ADAT” will allow you to send and 
receive four channels of audio at 88 2/96 kHz 
(per ADAT port; S/MUX II) or two channels 
at 176 4/192 kHz (per ADAT port; S/MUX 
IV)   In Standalone Mode, Optical Port B can 
only be set to ADAT when the interface is 
operating at sample rates of 88 2 to 192 kHz *
 
 
 
 
S/PDIF:
 
 
 Selecting “S/PDIF” allows the second optical 
input and output ports to convert optical  
S/PDIF signals into coaxial S/PDIF signals 
while simultaneously converting coaxial  
S/PDIF to optical S/PDIF   
 
 
 * Since ProFire 2626 has a maximum of 
eight analog inputs and outputs, optical 
port B is not necessary for A/D or D/A 
conversions at 44.1/48 kHz.  Optical port 
B can be used for A/D, D/A operation at 
sample rates above 48 kHz.
NOTE:  This parameter only displays sample 
rates (i.e., “44.1 kHz”, “48 kHz”, etc.) when the 
Standalone Mode Sync Source is set to “Internal.”  
If you are clocking the interface to an external S/
PDIF or Word Clock device, this parameter displays 
“Auto” and the interface automatically locks to 
the sample rate of the master device.  If you are 
clocking to an ADAT device, this menu provides 
the same options found under the S/MUX Mode 
parameter while in hosted mode (“Auto,”  
“S/MUX II (88.2 to 96 kHz),” and “S/MUX IV 
(176.4 to 192 kHz).”  See the S/MUX Mode 
description earlier in this section to learn more 
about these settings.
 Note: The coaxial and optical S/PDIF ports support 
a maximum sample rate of 96 kHz when operating 
in Standalone mode.  This is because optical S/
PDIF has a maximum sample rate limit of 96 
kHz.  As a result, when  ProFire 2626 is operating 
at sample rates above 96 kHz, this parameter 
automatically defaults to ADAT mode.
