1. Hi Frequency
Cutoff Control
This control varies the
frequency at which the
ES700P 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
ES700P 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 ES700P . 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 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
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.

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
+30
Cutoff should be set to 150-Hz and the Input Level
should be set to LINE. For Line
-3
Level operation a balanced ( Tip dB
Ring Sleeve ) cable should be
used. If the system is being INPUT GROUND
operated without a processor ,
UNGROUNDED
this Subwoofer can be

connected to the output of the
INPUT LEVEL
power amplifier as shown in the
diagrams and the Input Level
SPEAKER
should be set to SPEAKER. If
LINE
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.

3. Input Ground Switch
The ES700P expects the source feeding
it to be grounded. A system comprised
entirely of ungrounded equipment may
cause the ES700P 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 ES700P is fed
from the output of an amplifier or
powered mixer. The line level position is
for when the ES700P 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.

spl when set for speaker
level input. With a typical

full range companion
speaker this will give flat
response. In either line
3
or speaker operation it
will usually be desirable
to set the control at +3
4
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
