Using a Verona with a GPS clock

If you have a GPS clock or atomic clock, you can slave the Verona to the clock, improving the accuracy of the Verona to that of the clock.

Figure 3 – Slaving the Verona to a GPS clock

do this: Connect up as shown in Figure 3.

do this: The first time you use this arrangement, open the menu and run the Factory routine on all four units. This sets the Verona to 44.1kHz.

do this: Open the menu and set the Couple page to Bipolar.

The Verona will lock to the clock. All the outputs will be at 44.1kHz, at the accuracy of the clock.

do this: If you need 48kHz, press the Clock Frequency button.

do this: Use the Verona‘s outputs to synchronise the audio equipment together.

Note that a GPS clock relies on receiving a satellite transmission. Any gaps in GPS satellite coverage will result in the frequency accuracy of the outputs reverting to that of the Verona – which is quite adequate for audio use.
