Introduction

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
(
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.

just like an ordinary speaker along with the full range speakers. The
"INPUT LEVEL" switch should be set to "SPEAKER

the AC cord, the "INPUT GROUND" switch must be set to "GROUNDED." The may be wired before or after

the left or right inputs when using separate 's for each side or when used in a mono system. The

power from the amplifier driving the full range speakers. Please note that an external cross-over is not necessary.
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.

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.
frequency cutoff to maximum (160 Hz)
If an élite processor is used, set the high

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

except when operating at low levels. For
AT HIGH POWER LEVELS WHEN THE LIMITER IS OPERATING INCREASING THE SUBWOOFER LEVEL CONTROL WILL NOT
INCREASE THE OUTPUT. DO NOT INCREASE SETTING WHILE OPERATING AT HIGH LEVELS.
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 (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

most applications the control should be set between 0dB and +20dB.
A setting of 0dB on the SUBWOOFER LEVEL control is the correct starting point when setting up a sound system. From there the sound can be adjusted for 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. This also is the setting to give a sensitivity of 2.83 Vrms (1 watt 8-Ohms) for 100 dB spl when set for speaker level input. With a typical full range companion speaker this will give flat response. In either line or speaker operation it will usually be desirable to set the control at +3 to +6 to give some bass boost at low power levels. At levels approaching full power the built-in limiter will automatically reduce the gain to prevent over powering the subwoofer. Operation with settings significantly above +12 may clip the circuitry in the subwoofer reducing the dynamics of the music. Setting the subwoofer gain above +12 is only appropriate at low operating level.

3. Input Ground Switch

The LS700P expects the source feeding it to be grounded. A system comprised entirely of ungrounded equipment may cause the LS700P to hum or buzz. If you have a buzz or hum problem, try setting the switch to the "GROUNDED" position. The switch should otherwise be left in the "UNGROUNDED" position. Do not use the grounded position with an amplifier operating in bridged mode or when the sleeve of the input signal is live.

4. Input Level Switch

A switch is provided to switch input levels between speaker level and line level. The switch should be set to speaker level when the LS700P is fed from the output of an amplifier or powered mixer. The line level position is for when the LS700P is fed a signal 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) cables will reduce the sensitivity to hum and buzz.

5. Stereo Input and Parallel Thru Jacks

For normal operation, connect the LS700P just like an ordinary speaker, along with the Full-Range speakers and set the Input Level switch to SPEAKER. If the audio source does not have a ground pin on the AC cord, the Input Ground switch must be set to GROUND (GND). The LS700P may be plugged in before or after the Full-Range speakers. Use the Left and Right Inputs when using a single LS700P in a stereo system. Use either the Left or the Right inputs when using separate LS700P's for each side (or when used in a Mono system). The LS700P does not alter the signal to the Full-Range speakers, and will not draw any power from the host amplifier driving them. Please note that an external crossover is not necessary.
As well as accommodating the full range speakers, the PARALLEL THRU jacks allow many LS700Ps to be connected in a string (or otherwise in parallel). There is no practical limit to the number of LS700Ps that may be connected together.
