THE MX300 AND DIGITAL I/O
The MX300 is equipped with digital input and output connections (S/PDIF). The S/
PDIF input and output are the digital equivalent of the analog inputs/outputs. The
digital output on the MX300 is always active and will always mirror its analog output
counterpart. This allows you to plug in an analog input source and have it be output
as a digital stream.
The MX300 has three options for input sources which are configurable in the System
Menu: Analog Mono L (Left), Analog Stereo and Digital. (Press the System
button to access the System Menu; turn the Page/Select knob to scroll up and down
the menu.)

While in the System Menu, use Knobs A, B, and C to change values. As with all
equipment that receives digital audio streams, when setting the Input Source to
Digital, the MX300 can no longer use its own internal clock source for the audio
stream, and it is necessary to change the clock source from the MX300’s internal clock
to Digital as it needs to use the external clock source via the S/PDIF input.

If the Clock Source isn’t changed to Digital when the digital input source is select-
ed, there will be synchronization problems between the incoming digital audio stream
and the MX300’s processing, and the System Input Source menu will display DIG NO
LOCK. When the MX300 is properly synchronized with the incoming digital audio,
the System’s Input Source and Clock Source menus display DIG LOCKED.
The MX300 runs at 44.1 kHz or 48 kHz sample rate (using internal or external clock
sources). Do not connect external digital outputs to the MX300 that run at higher
sample rates (88.2 - 192 kHz) as the MX300 cannot accept them.
