The S/PDIF Inputs Cannot Be Routed to Other Channels on the Line
Mixer
By default, the S/PDIF I/O is ALWAYS assigned to channels seven and
eight. This cannot be changed.
8.5 The Preamps Noise Floor Is Higher When The Tube Drive Is
Engaged
Engaging the tube drive could increase the amount of noise in the
source signal. Turning up the tube drive and the gain simultaneously
could also increase the noise floor. However, mixing the amount of
tube drive and preamp gain can create interesting effects and sounds.
8.6 mLAN Returns Three And Four Do Not Work In ADAT Mode
mLAN returns three and four are not useable when in ADAT or in stand
alone mode. All return channels must be routed to channels one and
two in order to be monitored.
8.7 Word Clock Synchronization (Sync)
If you experience pops, clicks or distortion while recording it may be
due to incorrect Word Clock sync. Only one device can be the master
and all the rest must be slaved. For most applications, the computer
will be the master. In this instance, the FIREstation will be set to EXT
and mLAN. If the ADAT output of the FIREstation is connected to
another device such as a digital mixer, it is recommended that the
BNC output be connected to the BNC input of the receiving device (in
this case the external digital mixer).
