its right output. Output 2 will contain the original right data on its left output and a
muted signal on its right output. This mode can be altered by the dipswitch settings,
to a channel swap mode or a dual mono mode. These are described in more detail in
the Rear Panel Controls section below.
•
In Combine Mode two mono signals are combined to create a single stereo signal.
Output 1 will contain the input 1 left channel data on its left channel and input 2 left
channel data on its right channel. This mode can be altered by a dipswitch setting, as
with the split mode. Where either the left or right channel data of input 2 is output on
the right channel data of the output. If the two signals are of different sample rates,
a sample rate converter can be switched in place to convert the sample rate of input
channel 2 to that of input channel 1. In the Stereo/Mono Combine mode, output 2 is
always muted.
Bypass Mode – In Bypass mode, input 1 is routed to output 1 and input 2 is routed to
output 2. Input 1 is used as the master clock input. If input 2 is at a different sample rate
to input 1 then input 2 is sample rate converted to match input 1. If the signal from input
2 is lost then output 2 will be muted. However, if the signal from input 1 is lost then both
outputs will be muted and will only return once a signal is present on input 1.
Note that when the unit is operating in Bypass Mode the Type switch is ignored.
