Setting The Speaker Distance; Setting The Bass Sounds - JVC RX-7040B Instructions Manual

Setting the speaker distance

The distance from your listening point to the speakers is another
important element to obtain the best possible sound of the Surround
and DSP modes. Set the distance from your listening point to the
speakers.
By referring to the speaker distance setting, this unit automatically
sets the delay time of the sound through each speaker so that sounds
through all the speakers can reach you at the same time.
• If you have used Quick Speaker Setup on page 21, this setting is
not required.

Setting the bass sounds

You can adjust subwoofer and bass sounds precisely according to
your preference.
7 Subwoofer output—S WFR OUTPUT
You can select the type of the signal which can be transmitted
through the subwoofer. In other words, you can determine
whether or not the bass elements of the front speaker channels
are transmitted through the subwoofer regardless of the front
speaker size setting (either "SMALL" or "LARGE").
Select one of the following:
S WFR: LFE Select to emit only the LFE signals (while
playing Dolby Digital or DTS software) or the
bass elements of the "SMALL" front speakers
(while playing any source other than the above).
S WFR: LFE+MAIN
Select to always emit the bass elements of the
front speaker channels (MAIN). While playing
Dolby Digital or DTS software, the bass
element and the LFE signals are both emitted.
Note:
If you have selected "NO" for the subwoofer, this function is not
available.
7 Crossover frequency—CROSS OVER
You can select the crossover frequency for the small speakers
used. The signals below the selected frequency level will be sent
to and be reproduced by the subwoofer (or by "LARGE"
speakers when you have selected "NO" for the subwoofer).
Select one of the crossover frequency levels according to the
size of the small speaker connected.
