Troubleshooting Guide

If you experience difficulties when using your Verona, the following suggestions may help resolve the problem.

IMPORTANT! The GOLDEN RULES for using a Master Clock:

•The source equipment MUST be locked to the Master Clock.

•The Clock Frequency MUST match the sample rate(s) used in the system.

The unit fails to power up

•Ensure there is power available on the mains cable. Connect the power cable, ensure it is pushed all the way in and press the Power button. If there is a Power switch on the back panel, ensure this is set to the On (I) position.

•Check the rated supply voltage shown on the rear of the unit matches the local supply voltage.

•Check that the fuse has not blown - if so, correct any obvious cause then replace the fuse as described on page 32.

The DAC/DDC suddenly mutes, Verona repeats its’ power-up sequence

•This may be caused by short drop-outs or brown-outs on the AC supply. When the disturbance has passed, normal operation should be restored.

•Check for loose mains wiring.

The system fails to lock to Verona

•Check that the digital audio cables are of the correct type, correctly connected and not damaged. Damaged cables are a VERY common cause of malfunctions!

•Check that Verona is switched on and has settled for at least 1 minute.

•Check that Verona is set to the correct Clock Frequency (probably 44.1kHz).

•dCS Verdi and La Scala will only accept a 44.1kHz clock.

•dCS Purcell will only lock if the WClk page is set to WClk:In.

•dCS Elgar Plus and Delius will only lock if the MS page is set to MS:Sync.

•If you are using dCS Elgar Plus or Delius with Verona while upsampling to

176.4or 192kS/s Dual AES or 88.2 or 96kS/s Single AES, you will need software v4.30 or later for Elgar Plus or v2.30 or later for Delius.

•If Verona is locked to an External Reference, ensure the reference frequency is at a suitable frequency and the Couple menu is set to match the external reference.

•If Verona is trying to lock to an External Reference but is continuously displaying Locking, there is something wrong with the external reference generator, the menu settings or the cable. The external reference may be out of calibration, or at a frequency that the Verona cannot lock to.

•AC coupled cables are not suitable for use with Word Clock signals.

Periodic clicks are heard from the loudspeakers

•This is often caused by part of the system (usually the source equipment) not being locked to the Verona, while the DAC is locked. Check that the system is connected correctly, that the menu settings are correct and the master clock frequency matches the sample rates in use.
