Monitor Insert
The External A selector output (ie. all 5.1 sources) is automatically routed via a 5.1 insert point to which an
encoder/decoder system may be interfaced; this insert may be switched in/out of circuit using the Monitor
Options INS function (see next page). The insert send and return appear on two 25-way D-type connectors on
the centre section connector panel. The insert point also has connections for the two channel output from the
encoder, and the two channel input to the decoder. These allow monitoring of the encoder output (‘LtRt’)
signals and provide automatic routing of the External B selector outputs to the decoder inputs to enable
encoded recordings to be played back through the decoder. The logic for this is as follows:
• With no sources selected on External B, the encoder outputs are linked to the decoder inputs.
• Selecting any source on External B will route the External B outputs to the decoder inputs.
• Selecting EXT A and INS will monitor the insert return; if no source is selected on External B you will hear
the External A signals through the encoder and decoder. If a source is selected then you will hear the
decoded output of External B.
• Selecting EXT B and INS and selecting a source on External B will monitor External B.
• Selecting EXT B and INS with no source selected on External B will monitor the LtRt encoder outputs. The
LTR soft button lights to show this. Note that LTR is selected by turning off all other External B sources.
Monitor Metering
A dedicated set of six LCD bargraphs above the centre section provide a constant indication of ‘FOLLOW
MONITOR’ levels (ie. what you are currently listening to), plus a stereo meter for the SOLO/AFL bus and mono
PFL levels. See later for more on meter options. The ‘FOLLOW MONITOR’ meter feeds are available via a 25-
way D-type connector on the centre section connector panel, for use with external metering.
