Denon AVR-1683 Operating Instructions Manual page 20

NOTES:
- Assignment of low frequency signal range -
l
The signals produced from the subwoofer channel are LFE signals (during playback of Dolby Digital or DTS signals) and the low frequency
signal range of channels set to "SMALL" in the setup. The low frequency signal range of channels set to "LARGE" are produced from those
channels.
- Crossover Frequency -
l
When "Subwoofer" is set to "Yes" at the "Speaker Configuratron Settrng", set the frequency (Hz) below which the bass sound of the
various speakers is to be output from the subwoofer (the crossover frequency),
l
For speakers set to "Small", sound with a frequency below the crossover frequency is cut, and the cut bass sound is output from the
subwoofer instead.
NOTE:For ordinary speaker systems, we recommend settrng the crossover frequency to 80 Hz, When usrng small speakers, however,
setting the crossover frequency to a high frequency may rmprove frequency response for frequencies near the crossover frequency.
- Subwoofer mode -
l
The subwoofer mode setting IS only valrd when "LARGE" is set for the front speakers and "YES" IS set for the subwoofer rn the "Speaker
Configuration" settings (see pages 18, 19).
If "SMALL" is set for the front speakers or "NO" is set for the subwoofer, the subwoofer mode setting does not affect playback of low
frequency signal range.
l
When the "+MAlN" playback mode is selected, the low frequency signal range of channels set to "LARGE" are produced srmultaneously
from those channels and the subwoofer channel,
In this playback mode, the low frequency range expand more untformly through the room, but dependrng on the srze and shape of the room,
interference may result in a decrease of the actual volume of the low frequency range.
l
When the "NORM" playback mode is selected, the low frequency signal range of channels set to "LARGE" are only produced from those
channels. In this playback mode there tends to be little interference of the low frequency range rn the room
l
Try playing the music or movie source and select the playback mode providing the stronger low frequency range sound.
Input the distances from the listening position to the speakers and set the surround delay time.
Preparations:
Measure the distances from the listening position to the speakers (Ll to L3 on the diagram at the right).
LI: Distance from center speaker to listening position
Lz: Distance from front speakers to listening position
L3:
Distance from surround speakers to listening posrtion
CAUTION:
% Set the center speaker at the same distance from the front speakers (left and right) or the subwoofer,
or so that the difference in distance (L2 - Ll) is 5 feet or less.
% Set the surround speakers (left and right) at the same distance from the front speakers (left and right)
or the subwoofer, or so that the difference in distance (L2 - L3) IS 15 feet or less.
SL
SR
Use the 0 (left) and 0 (right) buttons to set the distance from the front speakers and subwoofer to the
listening position.
