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

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.

Bass Management

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.
