9.4.2.1. Digital Input & Output Select Buttons
These buttons are used to switch the digital connection between the AES/EBU XLR
connector (button out) and the S/PDIF phono connector (button in) for the digital
source and digital output.

Altering the Stereo/Mono Split/Combine Mode – In Split mode With switch 1 off,
channel A (Left) and B (Right) on the input are transferred to channel A (Left) of
outputs 1 and 2 respectively. With switch 1 on, channel A (Left) on the input is
transferred to channel A (Left) on output 1 and channel B (Right) on the input is
transferred to channel B (Right) of output 2. With switch 3 on (switch 1 is ignored),
channel A (Left) is transferred to both channels on output 1 and channel B (Right) on
the input is transferred to both channels on output 2.
In Combine mode with switch 1 off, channel A (Left) on input 1 is transferred to
channel A (Left) of output 1, and channel A (Left) on input 2 is transferred to channel
B (Right) of output 1. With switch 1 on channel A (Left) on input 1 is transferred to
channel A (Left) of output 1, and channel B (Right) on input 2 is transferred to
channel B (Right) of output 1.
Switching on the Sample Rate Converter - Switch 2 is used to turn the sample
rate converter on, or off and can be used in all modes. When there are two inputs
connected to the unit which are at different sample rates or which need to be
synchronised, then the sample rate converter should be switched on. If it is not, then
you may suffer from missed samples and bit errors affecting the signal output. If the
sample rates of the incoming signals are always going to be the same and are
synchronised, then switch the sample rate converter off, as leaving it on will worsen
the output signal (signal jitter will increase).
