LFE redirection for 5.0 and 8.0 PRIRs
If a 5.0 or 8.0 PRIR has been created, for example by using one or more of the
ONE
,
LsRs
, or
LbRb
methods, there is no virtual subwoofer, yet the user will need to route the LFE channel to some
destination.
If the user has no real subwoofer, the preamplifier or receiver can be set accordingly and the LFE
channel will be mixed into some or all of the main channels within the preamplifier.
If the user has a real subwoofer and needs therefore to maintain a separate LFE channel out of the
preamplifier, the
REL VOL
and
MIX BLOCK
settings can be used for redirecting the LFE into one
or more main channels within the Realiser. Four possibilities exist, as detailed in the tables below.
The LFE levels in the headings refer to the LFE level output by the preamplifier and present at the
input of the Realiser.
LFE at 0 dB, routing LFE to C only
LFE at 0 dB, routing LFE to C, LS and RS
