Crossover Frequency; Low Frequency Effect Attenuator; Dynamic Range Compression - JVC RX-DV31SL Manuel D'instructions

The distance from your listening point to the speakers is
another important element to obtain the best possible
surround sound from the Surround 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 Setup (see page 21), this setting is
not required.
Set the distance from the listening point within the range of
0.3 m (1 ft) to 9.0 m (30 ft), in 0.3 m (1 ft) intervals.
Notes:
• "10ft" is the initial setting.
• If you have selected "NO" for the center and surround speakers
setting, you cannot set the speaker distance for the center and
surround speakers.
Ex.:In this case, set "FRNT D" to "11ft,"
set "CNTR D" to "10ft" and
set "SURR D" to "9ft."

Small speakers cannot reproduce the bass sounds efficiently.
If you use a small speaker in any position, this unit
automatically reallocates the bass sound elements assigned
to the small speaker to the large speakers.
To use this function properly, set the crossover frequency
level according to the size of the small speaker connected.
• If you have selected "LRG (large)" for all speakers, this
function will not take effect.
