Insignia NS-R5100 AV Digital Home Theater Receiver
• ON (Auto surround mode)—The optimum
surround mode will be automatically selected
depending on the signal format being input.
Notes
• When the SPEAKER button is set to off, the
auto surround mode is invalid.
• Even when the auto surround mode is selected
and the same type of digital signal format is
being input, the optimum surround mode may
vary depending on whether the speaker type is
set to "N (None)" or not.
• When the auto surround mode is selected and
the PCM (2 channel) digital signal or the
analog stereo signal is being input, only the
stereo mode will be selected.
• When the auto surround mode is selected, the
surround modes other than the optimum
surround mode cannot be selected.
• When 96 kHz PCM signal is being input, only
the stereo mode will be selected regardless of
selecting either the auto surround mode or the
manual surround mode.
Modifying the speaker settings
After you have installed this receiver and
connected all the components, you should adjust
the speaker settings for the optimum sound
acoustics according to your environment and
speaker layout.
When you change speakers, speaker positions,
or the layout of your listening environment, you
should also adjust the speaker settings.
Modifying the speaker configuration
Use the speaker configuration menu to select
the size of each speaker. Select large or small
not according to the actual size of the speaker
but according to the speaker's capacity for
playing low frequency (bass sound below
frequency set on the "X-OVER" menu) signals.
If you do not know, try comparing the sound at
both settings (setting the volume to a level low
enough so as not to damage the speakers) to
determine the proper setting.
Depending on the speaker type, you can select
one of the following:
• L (Large)—Select this when connecting
speakers that can fully reproduce sounds
below crossover frequency.
• S (Small)—Select this when connecting
speakers that cannot fully reproduce sounds
below crossover frequency. When this is
selected, sounds below crossover frequency
are sent to the subwoofer or speakers which
are set to L when not using a subwoofer.
• N (None)—Select this when no speakers are
connected. When this is selected, sounds are
sent to the speakers which are not set to N.
• Y (Yes)/N (No)—Select depending on
whether a subwoofer is connected or not.
Notes
• When speakers are set to S, you should set
their crossover frequency correctly according to
their frequency characteristics. (For details,
refer to "Modifying the crossover" on page 19.)
• When SUB-W is set to N, FRONT is
automatically set to L.
• When the FRONT is set to S, CENTER and
SURR cannot be set to L.
Modifying the speaker distance
Use the speaker distance menu to select the
distance between the listening position and each
speaker to set the delay time for optimum
surround playback.
Modifying the crossover
You can adjust the crossover frequency within
the range of 40 ~ 200 Hz in 10 Hz intervals.
When speakers are set to S, low frequencies in
those channels that are below the crossover
frequency to output from the subwoofer or front
speakers which are set to L (when not using a
subwoofer).
Refer to the operating instructions of the
speakers to be connected. If the frequency
range of your speaker is 100 Hz~20 kHz, the
crossover frequency should be set to 100 Hz (or
slightly higher).
Modifying channel level settings
Modifying the current channel level
You can adjust the current channel levels as
desired. These adjusted levels are memorized
into user's memory (CAL) and not into preset
memory (REF 1 or REF 2).
After adjusting each channel level with test tone,
adjust the channel levels either according to the
program sources or to suit your tastes. (For
details, refer to "Adjusting each channel level
with test tone" on page 14.)
Memorizing the adjusted channel levels
You can memorize the adjusted channel levels
into preset memory (REF 1 and REF 2) and
recall the memorized levels whenever you want.

Note
• You cannot select the speakers set to N.
• You can select either M (Meters) or FT (Feet).
• Once a unit is selected, the distances are
automatically changed in the selected unit.
When setting the distance, you can set the
distance within the range of 0.0 ~ 9.0 meters in
0.3 meter intervals (or 0 ~ 30 feet in 1 foot
intervals).
• When enjoying multi-channel surround
playback with Dolby Digital and DTS sources, it
is ideal that the center, surround, and
subwoofer speakers should be the same
distance from the main listening position as the
front speakers. By entering the distance
between the listening position and each
speaker, the delay times of center, surround,
and subwoofer speakers are automatically
adjusted to create an ideal listening
environment virtually as if the center, surround,
and subwoofer speakers were at their ideal
locations respectively.
Note
Depending on the speaker settings, (N), some
channels cannot be selected.
Note
The LFE level can be adjusted within the range of
- 10 ~ 0 dB and other channel levels within the
range of -15 ~ +15 dB. In general, we recommend
the LFE level to be adjusted to 0 dB. (However, the
recommended LFE level for some early DTS
software is -10 dB.) If the recommended levels
seem too high, lower the setting as necessary.
