M-Audio Super DAC [9/12] Troubleshooting

TROUBLESHOOTING

Symptom: When power is applied, there are no LED's lit on the Super

DAC's front panel.

Solution: Make sure the correct power supply is properly plugged into

the unit and also into a live wall source or power strip. Also make sure the

unit’s Power button is pushed (and latched) in.

Symptom: When the digital audio source changes sample rates, or I select

a different digital input using the Format button, the audio is muted for a short

period of time.

Solution: This is normal as it takes a small amount of time for a digital

audio receiver to lock onto a digital audio source. In order to prevent spurious

noise, the Super DAC mutes its analog outputs until it sees a valid digital

signal for 200 milliseconds.

Symptom: When applying a digital signal to the Super DAC, the DAC's

"Data Valid" LED lights erratically or not at all.

Solution: The digital signal being input may be invalid or the digital

cable may be faulty.

Symptom: Valid digital data is coming into the Super DAC (the D/A

Valid LED is lit), but there is no audible analog audio output.

Solution 1: Check your analog output connections from the Super DAC.

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 extremely small waveform (one with very low volume) that

you are unable to hear.
