Bass management
When switched on, the low frequency content in the audio signal may be re-routed to
different loudspeakers, depending on their capabilities. Bass management redirects low
frequencies to the most capable loudspeakers in your current setup. For example, if you
have two small loudspeakers and a subwoofer, the low frequency signals will be directed
to your subwoofer instead of to your smaller main speakers.
Crossover frequency
: All output signals use the same crossover frequency to
ensure that coherent signals on multiple output channels have matched phase
responses when passed through the bass management and bass re-direction
processing. However, you can adjust it here or bypass it.
Enable filtering
: Determine whether the bass management filtering should be on
or off for the individual output channels.
Panning
: Adjust the panning of the bass management signal derived from each
output channel into the two bass management low-frequency channels. Adjust
bass according to your listening position.
Redirection levels
: Adjust the level of the two bass management low-frequency
channels being added back to the output channels.
Redirection balance
: Adjust the relative levels between the two bass
management low-frequency channels in each output channel.
LFE input to ceiling
Some record labels use the LFE (Low Frequency Effect) channel on their discs for height
information instead of low frequency effects. This means that the LFE input channel
should be directed to a 'full range' speaker placed above the listener. Setting the
LFE
input to ceiling
to
Yes
directs the audio signal on the LFE input to a loudspeaker with a
'ceiling' speaker role.
Subwoofer
Here, you can adjust the relative delays of the subwoofer and the main loudspeaker
channels and adjust the allpass frequency to better match the subwoofer to the main
speakers.
Time alignment
: Allows you to adjust the relative delays of the subwoofer and
the main loudspeaker channels. When the value is positive, the subwoofer is
being delayed relative to the main loudspeaker channels. When the value is
negative, the subwoofer output precedes the main loudspeaker channels by the
displayed value.
All-pass frequency
: There is a first-order allpass filter in the signal path of the
subwoofer output. This can be adjusted to better match the subwoofer to the
main speakers in cases where either the placement or the phase responses of
the loudspeakers result in poor matching of the upper- and lower-frequency
components through the crossover band.
Volume
Adjust the volume level of the television. The volume level you set here is the volume
level the television will start at each time you switch it on, no matter which volume level it
was at when you switched it off.
Here you also set the highest volume level allowed in normal usage. This can be used to
limit the maximum output of the television.
