CONFIGURING THE S170i
16
BASS/TREBLE
From the <Audio setup> menu, select the <Bass> or <Treble> item using the remote's [Cursor
keys. Using the [Cursor ] keys, you may increase or decrease Bass or Treble settings by ±12 dB by 1
dB steps.
• Bass/treble settings affect only the front channels (left, center, and right), and are active in all listening
modes
• It is often better to "cut" (a minus setting) than boost (a plus setting); for a "warmer" overall sound
try reducing Treble by a few dB instead of boosting Bass, and vice versa.
• If you frequently find yourself selecting large tone control settings, you may be better served by
reexamining your choice of loudspeakers, and your loudspeaker and listening-position locations to
better exploit your room's acoustics.
LFE CHANNEL
The Low-Frequency Effects channel—-the "point-one" channel in "5.1/6.1"—-is active only with Dolby
Digital or DTS multichannel sources. LFE is employed most often as a supplementary channel to enhance
the dynamic range of very low-frequency sounds; it should not be confused with the S170i's Subwoofer
output-channel, which may carry most or all bass information from some or all channels, depending on
the configuration of the <Speaker setup> menu page.
From the <Audio setup> menu, select the <LFE channel> item using the remote's [Cursor
Using the [Cursor ] keys, you may decrease the LFE channel setting by as much as 10 dB in 1 dB
decrements.
In most systems the LFE channel setting may be left at 0 dB (no change), because the S170i's Bass Limiter
(see below) will be set to prevent subwoofer overload. However, if your subwoofer's headroom is known
to be limited, or if the low-frequency effects of film soundtracks generally seem excessive in your system,
you might profitably try decreasing the <LFE channel> setting by a modest degree.
