Clock Source
500R8 can be integrated into your studio as either a master or slave device by configuring its
Clock Source using the software control panel for your chosen device - Cranborne Audio’s USB
Control Panel for Windows machines, or Audio MIDI Setup for macOS.
The Clock Source can be assigned to 5 different options to allow for maximum integration into
your studio space. These options are as follows:
Internal Clock (default, recommended)
Allows 500R8 to generate its own accurate and low-jitter clock from it’s internal clock.
This setting should be used when 500R8 is connected to a device via USB and is
intended to be used as the clock master to the system.
USB Recovered
Allows 500R8 to slave from a device connected to its USB port. This setting should be
used if you have multiple audio interfaces connected to the same machine that you
would like to be clocked from USB.
ADAT Recovered
Allows 500R8 to slave from a device connected to the ADAT stream. This setting should
be used if you need 500R8 to slave off of the device that is connected via ADAT.
Word Clock
Allows 500R8 to slave from a device connected to the Word Clock Input connector. This
setting should be used if you need to clock 500R8 off of an external clock master
connected via a word clock BNC cable.
