ONITOR NSERT
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 INS softkey in
MONITOR OPTIONS. 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.

ASS ANAGEMENT
Selecting the BASS softkey in MONITOR OPTIONS produces a layer of
bass management options:
80H Inserts a 7th order, 80Hz, low pass filter into the LFE monitor
bus, to deal with listening to 5.1 material that has a full range,
unfiltered, LFE channel.
BMN Turns on the Bass Management system. This is designed to extend the low frequency response of the
monitoring system, and to simulate the 5.1 monitoring systems in TV and domestic environments. It inserts
12dB per octave, 80Hz high pass filters in the L, C, R, LS, RS monitor outputs, and feeds a mono sum of these
five outputs to an 80Hz, 24dB per octave, low pass filter, which is summed with the LFE monitor bus. Post
this summing point, the combined signals feed via a 10Hz subsonic high pass filter before reaching the
subwoofer monitor output. These are the default filter slopes. Internal links (see appendices for details) allow
them to be set to 12dB or 24dB per octave and to select whether or not the surround channels are included.
Note that this option is stored separately for each set of speaker outputs (like the level calibration), so it is
possible to have Bass Management enabled on one set of speakers and not on others.
LF0 Normally, the LFE bus level is increased by 10dB post the main monitor level control, as this is a requirement
for DVD playback. If you are mixing for SACD, or any other format that requires unity gain on the LFE
channel, select LF0 to restore the LFE bus level to unity gain.
Selecting NEXT produces a second layer of options:
A2B Retains use of the Main 5.1 subwoofer, even when you switch to
the ALT 5.1 loudspeaker selection.
BMA Uses the Alt 5.1 subwoofer instead of the main subwoofer for
bass management when MINI A is selected and BMN is on.
BMB Uses the Alt 5.1 subwoofer instead of the main subwoofer for
bass management when MINI B is selected and BMN is on.
Pressing RTRN returns you to the top layer of the MONITOR OPTIONS selection.
