S2125A

Introduction

Congratulations on your purchase of the LS701P. The LS701P is a premium-quality integrated subwoofer
and power amplifier. It’s been designed as an easy-to-setup addition to any P.A. and will extend the
bass of a typical sound system with the least amount of complication.

Note: The LS701P is primarily intended to operate with line-level signals, but will also work with
speaker level signals.

Configuration

The LS701P can be
used in several different
configurations. The basic
system is a single LS701P
used for each full-range
loudspeaker (multiple
LS701Ps can also be used
with individual full-range
loudspeakers). A single
LS701P can also be used with
a stereo system if both Input A
and Input B are used..

Note: Left and right signals
can be directly connected
to a single LS701P maintaining
their stereo separation. Plug the two
audio signals (left and right) into the Input A
and Input B jacks, the LS701P combines the
line-level signals properly but also allows you
to connect the respected left and right full­range powered loudspeakers by connecting
them directly to the Thru jacks.

Note: When sending a mono source signal into
the LS701P, you can use either Input A or Input B.

1. Input Level Switch

The Input Select switch is provided to choose
between line-level and speaker level. The line­level position is for use when the LS701P is fed
a signal directly from a processor, electronic
crossover or the output of an un-powered 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.
This switch should be set to speaker level when
the LS701P is fed from the output of an amplifier
or a powered-mixer.

WARNING: Do not plug in two speaker level
sources to a single LS701P.

2. LS701P Level Control

The Level control adjusts the amount of bass
added to the sound system by the LS701P. This
Level Control adjusts for the relative sensitivity of
the companion full-range loudspeakers and the
desired system frequency response. This control
should be set by listening while operating at a
medium level and then not changed.

Note: It is not recommended
to set this control at high levels

since the limiter determines the

output level.

Note: A setting of 0 dB on the

LS701P 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. Boost Frequency Control

The Boost Frequency control allows the user
to change the character of the subwoofer
sound. This control will have less effect when
operating into limiting.

4. HF Rolloff Frequency Control

The HF Rolloff Frequency control varies the
frequency at which the LS701P rolls off the high
frequencies, which provides part of a crossover
function. This crossover function also combines
with the natural low frequency rolloff inherent
of the full-range loudspeaker (when the LS701P
is not used with a separate processor). As an
example, a Yorkville élite processor may be
used to provide the LF rolloff of the full-range
loudspeaker. Ideally the LS701P would then be
wired ahead of this processor. In this case the
LS701P HF rolloff should match the LF crossover
point of the separate processor. A separate
processor may be used ahead of the LS701P in
which case the LS701P HF rolloff should be set to
maximum. Most Yorkville powered loudspeakers
include a LF rolloff switch, which makes it
unnecessary to use an electronic crossover.

5. Input Jacks

The inputs are set up to make it easy to hook up
your LS701P to almost any audio system with a
minimum of hassles. There are two groups of input
jacks, Input A and Input B. Each set provides a
Thru connection to allow daisy-chaining. Input A
jacks includes ¼ inch jacks, a male XLR jack and
female XLR jack. Input B jacks use a single XLR
male jack and a single female jack. If these two
sets of jacks are used simultaneously the signal is
mono summed within the LS701P to generate the
signal to drive the subwoofer.

Note: For speaker level operation, connect

At high power levels when the limiter is operating, increasing the subwoofer level control will not

increase the output. Do not increase the setting while operating at high levels.

Note: The LS701P’s built-in stand mounting adapter can be used with the Yorkville SW-Teletube accessory to support

our full range cabinets. The support tube can be adjusted up to its full 5-foot 4-inch extension safely

as long as the LS701P is NOT inclined more that 10° (10-degrees).

WARNING: Larger or heavier cabinets should NOT be used!

SELECT

the LS701P just like an ordinary speaker
along with the full-range loudspeakers. Set
the Input Level switch to Speaker if the signal
is coming directly from a power amplifier,
‘powered’ mixer, or other powered source.
If the LS701P is receiving the signal from
a non-powered mixer, a line-level signal
processor (as in an equalizer) or another
line-level source, set the input switch to Line.

The LS701P may be plugged in before or after
the full-range loudspeaker. The LS701P does
not alter the signal to the daisy-chained (thru)
loudspeakers and will not draw any power from
the host amplifier/processor driving them. Also,
note that an external crossover is not necessary
when using the LS701P.

Note: As well as accommodating full-range

loudspeakers, the Thru jacks allow many

LS701Ps to be connected in a string (parallel).

There is no practical limit to the number of

LS701Ps that may be connected together

(even greater than 30).

6. Protection

The LS701P has circuitry to prevent clipping,
over current and over excursion. At high levels
the limiter will limit the gain of the LS701P and
hence if the user attempts to set the subwoofer
level control at a high level, the resulting setting
will be incorrect. The level control should be set
while operating at low levels (under 10 watts).

Note: If the level control is set too high, due to
high operating levels there will be excessive
bass when operating at lower levels possibly
causing low frequency feedback.

7. NX Link Outputs (NX Series
Full-Range Loudspeakers)

Many of the NX powered loudspeakers have a
link output. The LS701P may be driven from this
output. This allows the internal mixer to be used
while still driving the LS701P powered subwoofer.
