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.

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.

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 

Cutoff should be set to 150-Hz and the Input Level 
should be set to LINE. For Line 
Level operation a balanced (

Tip 

Ring Sleeve)  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.

For normal operation connect the 

 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.

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)

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
