USB Type-A Ports (14)
These ports are not functional.
S/PDIF Digital Outputs
The S/PDIF digital output ports are for connecting OX's left/right stereo output signals to
the digital input(s) of a computer audio interface or other digital audio equipment.
The stereo signal at the digital outputs is same stereo signal as the signal at the MON /
LINE and HEADPHONE outputs. Both digital outputs carry the same stereo signal, and
both digital outputs can be used at the same time.
Digital signal levels can be adjusted with the master fader in the OX software app. Digital
levels cannot be changed with OX's hardware controls.
Note: The sample rate of the digital outputs is fixed at 44.1 kHz.
Tip: If connecting OX to the S/PDIF input of an Apollo audio interface, activate the
realtime S/PDIF sample rate conversion feature (SR CONVERT) in Apollo Console's
S/PDIF channel input strip to enable compatibility with all Apollo sample rates.
Coaxial S/PDIF Digital Output (15)
This stereo S/PDIF digital output jack accepts a 75-ohm coaxial RCA (phono) digital
audio cable.
Tip: Use this port to digitally connect OX's stereo output signal to the S/PDIF
input port on Universal Audio's Apollo FireWire and Apollo 8 audio interfaces.
Note: For optimum results, use a 75-Ohm RCA cable that is specifically designed
for digital audio.
Optical S/PDIF Digital Output (16)
This stereo S/PDIF digital output port accepts a TOSLINK optical cable.
Tip: Use this port to digitally connect OX's stereo output signal to the S/PDIF
optical input port on Universal Audio's Apollo Twin, Apollo Twin MkII, and Apollo
8p audio interfaces.
Important: Although TOSLINK optical cables are also used for digital connections
in ADAT format, this port outputs S/PDIF format only and is incompatible with
ADAT optical inputs.
