flash between blue and red. After 5 minutes of inactivity, the LED
switches to blue flashing, indicating that automatic connection is
disabled.
To enter pairing mode, press the button for 3 seconds until the

the full volume output.

Digital Coaxial Input/Output:

The function of the digital coaxial connector depends on the
selected input. It acts as an output when Bluetooth or USB is
selected and as an input when S/PDIF is selected.

Balanced XLR Analogue Output:

The balanced XLR output provides a balanced analogue audio
signal.

USB-C Input:

The USB-C port is used for data transfer and connects the ZEN
One Studio to the audio source. Please note that drivers may need
to be installed for use with a PC. Visit
