Introduction
The LS2100P is a premium quality integrated subwoofer and
power amplifier. Created as an easy-to-setup
addition to any P.A., the LS2100P will extend
the bass of a typical sound system with the
least amount of complication. The LS2100P
has been intended to operate primarily
with line level signals (with the option to
accept Speaker Level signals).
Configuration
The LS2100P may be used in several different
configurations. The basic system is a single
LS2100P used for each full range enclosure
or multiple LS2100Ps along with individual full
range enclosures. The LS2100P accepts, and
combines, the signals from separate line level
(e.g. Left and Right) sources. Using the Mono
Blend XLR input combines the second line level signal
properly to drive the internal speakers and does not
affect the stereo separation of the full range enclosures. When
used in a setup where only one signal is provided to a speaker, such as a mono system or stereo
with more than one LS2100P, you can use any of the Link jacks.
1. Input Level Switch
The Input Level switch is provided to switch
the Input Level between line level and
speaker level. This switch should be set to
speaker level when the LS2100P is fed from
the output of an amplifier or ‘powered’ mixer.
Do not plug in two Speaker Level sources to
one LS2100P. The line level position is for use
when the LS2100P is fed a signal directly from
a processor, electronic crossover or the output
of an ‘unpowered’ mixer. When using the line
level mode, the use of balanced (Tip, Ring,
Sleeve) and/or XLR cables will reduce the
unit’s sensitivity to hum and buzz.
2. LS2100P Level Control
The LS2100P Level control adjusts the
amount of bass added to the sound system
by the LS2100P. This adjusts for the relative
sensitivity of the companion full range
speakers and the desired system frequency
response. This control should be set by
listening while operating at a medium level
and then not changed. It is not possible to
set this control properly at high levels since
the limiter is determining the output level.
A setting of 0 dB on the LS2100P Level
control is the correct starting point when
setting up a sound system. From there,
adjustments can be made for the best sound.
The 0 dB mark refers to the setting that will
give full power when the line input is used
and the input signal is at a level of +4 dBV.
3. Shape Control
The Shape control enables tweaking of the
most effective sub frequency, 50 Hz. You can
boost or cut the equalization of the enclosure
(50Hz) by a range of 6 dB (+ 3dB / -3dB).
4. HF Rolloff Frequency Control
The HF Rolloff Frequency control varies the
frequency at which the LS2100P rolls off the
high frequencies. This provides part of a
crossover function. This crossover function
also combines with the natural low frequency
rolloff inherent of the full range enclosure
(when the LS2100P is not used with an élite
processor). An elite processor may be used
to provide the LF rolloff of the full range
loudspeaker. Ideally the LS2100P would then
be wired ahead of this processor. In this case
the LS2100P HF rolloff should match the LF
crossover point of the elite processor. The
elite processor should be set in the mode
intended for use with a subwoofer. An
elite processor may be used ahead of the
LS2100P in which case the LS2100P HF rolloff
should be set to maximum.
