3.1 RJ12 control port
The 6 wire RJ12 port enables the LT2020E to be controlled by a proprietary
LEAF controller such as the TC3.
3.2 4 way DIP switch module
The rear panel accessible 4 position DIP switch controls functionality of the LT2020E.
The table below summarizes the settings: The individual switches are labelled with
their switch number and ON
– OFF position.
NOTE: The interface will only read the DIP switch settings on power-up. The unit must
be powered off and then back on again for it to respond to any change of the DIP
switch settings.

3.3 Digital Coax (S/PDIF) audio inputs:
The upper row of RCA sockets 1 to 16 are configured as digital coax (S/PDIF) stereo
audio input ports. They can be used as either alternative audio inputs (selectable with
discrete Audio Only commands) or the input points for audio only sources.
3.4 Stereo RCA analog outputs
The lower 2 rows of RCA sockets 1-16 are configured as stereo analog audio outputs
for connection to local devices such as centralised external amplifiers.
The source audio for these outputs can be either an HDMI input source, digital coax
(S/PDIF) stereo connector input or audio return from a zone breakout input.
The RCA outputs may be routed manually or automatically (the default).
With automatic routing active, the RCA audio outputs will follow the zone audio output
of the same number. (example: If zone 4 is selected to source 2, then in automatic
mode the RCA audio will also come from source 2).
