Monitor Insert

The External A selector (ie all 5.1 sources) output 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 key (see page 4-21). The insert send and return appear on two 25-way D-type connectors on the
connector panel. The insert point also has connections for the two channel output from the encoder and the 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 for playing back encoded recordings 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 key lights to show this. Note that LTR is selected by turning off all other External B sources.

Monitor Options

A wide range of monitor options are available via the soft keys and associated display in the Monitor Control
Section. Pressing the MONITOR OPTIONS button above the display produces the following choices; press the
button below an entry to select that option.
INS – This switches the encoder/decoder insert into the monitor path for use with 5.1 monitor sources selected
via the EXT B monitor selector.
PFM – This routes the PFL signal to the Mini A loudspeakers. In this mode the PFL level is controlled by the PFL
level control only - the Monitor and Mini level controls have no effect.
SRA – Both sets of Main speaker outputs are capable of handling six channels. If you are mixing in 5.1 and and
the client turns up with an alternative set of 'front' (LCR) speakers only, the surround feeds may be locked to the
Main A outputs by selecting the SRA (Surround on A) function.This allows you to switch to the alternative LCR
speakers, connected to the Main B output, and still maintain full surround monitoring. A further option (ALFE –
see page 4-21) enables the subwoofer output to be included in this arrangement.
LRA – Similar to the SRA function except that the LCR monitor feeds are locked to the Main A outputs but an
alternative set of surround speakers may be selected by switching to the Main B output. This can be useful in
rooms that work on both music, using full bandwidth separate surround speakers, and film using multiple lower
powered surround speakers.
