Troubleshooting
Symptom: When power is applied, there are no LED's lit on the
Flying Calf's front panel.
Solution: Make sure the power supply is properly plugged
into the unit and into a live wall source or power
strip. Also, make sure the Calf's Power button is
pushed in and latched.
Symptom: When first turning the unit on, small bursts of noise
or a "pop" sound are sometimes heard.
Symptom: When the S/PDIF source sample rates change, small
bursts of noise or a "pop" sound are sometimes
heard.
Solution: This is normal as it takes a small amount of time for
an S/PDIF receiver to lock onto a digital audio
source. Be sure to turn down your mixer or amplifi-
er before powering up the Flying Calf or changing
sample rates.
Symptom: When applying a digital signal to the Flying Calf, the
Calf's "Data Valid" LED light is erratic or doesn’t
light at all.
Solution: The S/PDIF digital signal may be invalid or the
S/PDIF cable may be faulty.
Symptom: Valid digital data is coming into the S/PDIF input
(the Data Valid LED is lit), but there is no audible
D/A output.
Solution 1: Check your analog output connections from the
Flying Calf.
Solution 2: The digital data source may be sending valid data,
but the data could be static (non-changing or DC).
Verify that digital source material is actually valid.
Solution 3: The digital data source may be sending valid data,
but the data could represent an audio signal that is
so quiet that you are unable to hear it. In this case,
nothing is wrong.
