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 pre high pass filter

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 Appendix for

details) allow the links 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 loudspeaker 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.

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.

RTRN – Returns you to the top layer of the MONITOR OPTIONS selection.
