While you operate both RX1 and RX2, usually you need to listen to either only one of them or
both of them, but in different channels (left / right). To do that we added special functions to the
E-Coder panel, which set the mixer for both RXs.

Listen both RX1, RX2 – default settings, both RXs have equal volume in both channels.
Listen RX1 only – listen to the RX1 in both channels.
Listen RX2 only - listen to the RX2 in both channels.
Listen RX1 in left channel, RX2 in right – listen to the RX1 in the left channel and RX2 in
