Introduction
The LS700P is a premium quality integrated powered subwoofer and amplifier. Created
as an easy-to-setup addition to your PA, the LS700P will extend the bass of a typical
sound system with a minimum of complication, and hence is intended primarily to
operate with speaker level signals.
Configuration
The LS700P may be used in several different configurations, the minimum standard
system is one LS700P used with a pair of full range speakers. The LS700P accepts the
signal from separate Left and Right sources simultaneously. It then combines them into
one signal (to drive the internal speakers). 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 LS700P, use
either the Left or Right input.
USER NOTE:
This
Subwoofer
may be driven from Speaker Level
or Line Level signals. If an
élite processor
is used,
this Subwoofer should be plugged into the
SUB
output of the processor. The
High–Frequency
Cutoff
should be set to
150-Hz
and the
Input Level
should be set to
LINE.
For
Line
Level
operation a balanced (
T
ip
R
ing
S
leeve) cable should be
used. If the system is being
operated
without a processor
,
this
Subwoofer
can be
connected to the output of the
power amplifier as shown in the
diagrams and the
Input Level
should be set to
SPEAKER
. If
none of the equipment has a
U-
ground,
the
INPUT GROUND
should be set to
GROUNDED.
Otherwise the
INPUT GROUND
should be set to the position that
best minimizes the hum.

just like an ordinary speaker along with the full range speakers. The
"
INPUT LEVEL
" switch should be set to "
SPEAKER
." If the audio source does not have a "U" ground, eg. a ground pin on
the AC cord, the "
INPUT GROUND
" switch must be set to "
GROUNDED
." The
may be wired before or after
the full range speakers. Use the left and right inputs when using a single
in a stereo system. Use either
the left or right inputs when using separate
's for each side or when used in a mono system. The
does not alter the signal to the full range speakers in any way. The
will not draw any
power from the amplifier driving the full range speakers. Please note that an external cross-over is not necessary.
1. Hi Frequency Cutoff Control
This control varies the frequency at
which the LS700P rolls off the high
frequencies. This provides part of
a crossover function. This crossover
function also combines with the natural
low frequency roll off inherent of the
full range cabinet (when the LS700P is
not used with an élite processor). This
control should be set to the closest
possible frequency to 20 Hz below
the crossover point that the full range
speakers processor uses as it's crossover
point.
If an élite processor is used, set the high
frequency cutoff to maximum (160 Hz)
2. Subwoofer Level Control
The subwoofer level control adjusts the
amount of bass added to the sound
system by the LS700P. 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. Setting the level too high will over
load the circuitry causing a loss of bass
dynamics. The level control should not
be set above the 9 o’clock position
