Mode Switch and Display
The ADC1 can be programmed to function in a variety of conversion modes, including sample rates, bit depths, and output formats, using internal and/or external clock sources. This programming is all done through the Mode Switch. The Mode Display shows the selected mode in a concise format.
The Mode Switch is a momentary toggle switch. There are two ways of operating the mode switch:
1.Press
2.Press and Hold
Pressing the Mode Switch momentarily and then releasing it results in a particular change to the ADC1 conversion mode, while pressing and holding the switch results in a different change.
To program the conversion mode
•Press the Mode Switch up repeatedly to cycle through the clock source and sample rate options for the Main Outputs.
•Press the Mode Switch down repeatedly to to cycle through the sample rate and bit depth options for the Aux Output.

•Press and hold the Mode Switch down for approximately 3 seconds to switch between AES/EBU and ADAT mode for the Optical Output.
•Press and hold the Mode Switch up for approximately 3 seconds to reset the ADC1 to Factory Default settings.
Details about all of these actions follow.
Programming the Outputs
Pressing up repeatedly on the mode switch cycles through the clock source and sample rate options for the Main Outputs. The Main Outputs can be set to operate at a fixed frequency using the internal clock source, or they can be set to follow and lock to an external clock source.
Locking to an External Clock Source
The ADC1 can sync to a variety of external clock sources, including Word Clock, Super Clock, AES, and SPDIF. Once the ADC1 acquires sync, it will perform conversion at the sample rate of the external clock.
