  Lindsey MartinSep 10, 2025
  If your DCS Media Converter fails to power up, take these steps: * Ensure the mains cable is securely connected and the unit's mains switch is On. * Verify the rated supply voltage on the unit's rear panel matches your local supply voltage. * Check the fuse; if it's blown, identify and fix the cause before replacing it. * Make sure the mains cable is fully inserted into the mains inlet at the rear of the unit.

What to do if one output channel is low or absent on my DCS 900E Media Converter?

  Ensure that all cables are connected correctly and are not damaged. Verify that the balance is not offset elsewhere in the system. If the level trimmers on the rear panel have been adjusted, check that one has not been set much lower than the other.

Why won't the level trimmers on the rear panel of my DCS Media Converter change the input level?

  Ensure the trim tool or screwdriver you are using is narrow enough to reach the adjuster (about 2.5mm or 0.1” diameter) and long enough (at least 12mm or 0.5”). The trimmer may be at the end of its travel - try turning it several times the other way. It is a 20-turn device.

  If the audio output from your DCS Media Converter is low or absent: * Check all cables for correct connection and damage, as damaged cables are a very common cause of malfunctions. * Ensure both the source and destination equipment are powered on and configured correctly. * Verify that an audio signal is present on at least one of the inputs. * Make sure that the Mute function is not enabled (LED off).

  If the level trimmers on the rear panel of your DCS Media Converter aren't changing the input level: * Make sure the trim tool or screwdriver you're using is narrow enough (about 2.5mm or 0.1” diameter) and long enough (at least 12mm or 0.5”) to reach the adjuster. * The trimmer might be at the end of its travel; try turning it several times in the opposite direction. It's a 20-turn device.

Why does my DCS 900/902 Media Converter show overload when the external meter doesn't?
- A
  Aaron HoSep 18, 2025
  The dCS 900 / 902 monitors internal points and data word values to calculate overload. This may lead it to indicate an overload even if the final external data word doesn't show it. For example, it could be due to a very narrow but large spike. Some digital meters are quite insensitive to overloads. If the dCS 900 / 902 indicates an overload, it is likely accurate. You have the option to disregard it.

What to do if the DCS 900E Media Converter unit fails to slave to a Master Clock?
- B
  Becky Beard MDSep 7, 2025
  Press the Master/Slave button to select the appropriate mode. If a suitable reference is connected, the LED should light and the unit should lock after a few seconds. Check that the Reference In or Clk In cable is connected correctly and is not damaged. Verify that the Master Clock is switched on, set to the correct sample rate, and doesn't need recalibration. You can connect a different piece of digital equipment to test the locking capability of the unit. If the condition persists, contact your Distributor or dCS.
