Note: For speaker level operation, connect
the NX720S 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 NX720S
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 NX720S may be plugged in before or after
the full-range loudspeaker. The NX720S 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 NX720S.
Note: As well as accommodating full-range
loudspeakers, the Thru jacks allow many
NX720Ss to be connected in a string (parallel).
There is no practical limit to the number of
NX720Ss that may be connected together
(even greater than 30).
6. Protection
The NX720S has circuitry to prevent clipping,
over current and over excursion. At high levels
the limiter will limit the gain of the NX720S 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 NX720s may be driven from this
output. This allows the internal mixer to be used
while still driving the NX720S powered subwoofer.

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 NX720S’ built-in stand mounting adapter can be used with the
Yorkville SW-Teletube
accessory to support
our
E160
cabinets. The support tube can be adjusted up to its full 5-foot 4-inch extension safely
as long as the NX720S is NOT inclined more that 10° (10-degrees).
WARNING: Larger or heavier cabinets should NOT be used!
