Power, Limit and Clip
LED -
The Power LED
illuminates green when
power is on, the yellow
when operating at full
power and the limiters are
functioning and the Clip
LED illuminates when
the signal is too strong
(adjustment is needed to
either the input’s signal or
the input level control).
Level Control -
Allows the
audio level of the cabinets,
linked in a chain, to be
individually adjusted. It does
not adjust the level of the
Link jacks. Set at ‘0’ (center)
for most applications.
LF Rolloff -
For use with a
subwoofer, the LF Rolloff
shuts off the low frequency
boost and filters out
signals below 100 Hz. This
only affects the signals to
the internal amplifier and
does not affect signals
going out from the internal
mixer, or to signals
passing through the Link
connections.
Mixer On/Off -
This switch
turns the NX55P Series
Two’s internal mixer on
and off, the LINK jacks
still function.
*Note: these units have
been designed to interconnect multiple NX55P Series
Two cabinets (up to 12+) via the Link. When linking a
maximum of 3 internal mixers can be used (activated).
Mic Input/Level -
Connect a regular mic into the Mic input
and use the control to adjust the level. Phantom power is
built–in for condenser microphones.
Line/CD inputs -
These 1/4-inch inputs allow line-level sources
such as smartphones or other sources such as mixers to be
connectedm, use the control to adjust the level.
If both inputs are used the signals will be blended into
mono. The inputs are balanced and unbalanced 1/4-
inch plugs can be used.
Treble and Bass Controls
-
These controls affect
the signals from devices
plugged into the Line/CD
and Mic inputs. The signal
through the Link will also be
affected. These controls do
not affect signals coming
into the cabinet from the
Link connections.
Link -
These parallel jacks
allow multiple NX55P
Series Two cabinets to be
connected together. The
Link Jacks are the correct
input to use when driving
the NX55P Series Two from
an external mixer.
Power Switch -
This turns
the power On and Off to
the cabinet.
Note; a cabinet that is one
of the cabinets in a chain,
but turned off might cause
hum (or buzz) in the other
cabinets.
Fuse -
The mains fuse
should never blow even
in extreme operating
conditions. A blown fuse
will generally mean that
excessive mains voltage
has been applied or there’s
a serious fault with the
unit. Self resetting thermal
switches are built into the
power transformer as well
as the internal heat sink. These will not trip even under the
most extreme operating conditions and are provided only
for safety reasons.
Unbalanced operation: When connecting an unbalanced
source (such as a mixer with RCA outputs) to balanced
inputs such as an NX55P Series Two, the best hum
rejection can be achieved by running a balanced
connection right to the unbalanced plug. The return
connection should be connected to ground at the
unbalanced plug. The NX55P Series Two does not
connect the AC power ground directly to the input signal
ground. This will eliminate most ground problems.
