4.2 Quick Start 
After connection of all cables and power-on of the device, the configuration of the OctaMic XTC 
starts in the menu SETUP – Options - Clock. Choose a clock source and a sample rate. 
The next step is the GAIN setting. Press the desired SELECT button and adjust the gain with 
the encoders, so that the two level meters do not show overload. 
The digital output to send out the converted analog signal is defined in SETUP – Options – Digi-
tal Routing. Press encoder 2 to navigate downwards through the list, for example to ADAT Out. 
By turning encoder 2 the signal source of the ADAT output can be set to Mic 1-8 (default). 
The OctaMic XTC stores all settings before switching off, and sets them automatically when 
switching on the next time. The storing process is triggered 5 seconds after the last change.
