9. Line/CD Control
This control adjusts the volume level of devices
plugged into the Line/CD input. The signal out
to other cabinets, from this device, through
the link connections will be affected as well. A
line-level signal and microphones can be con-
nected simulataneously.
10. Treble and Bass Controls
These controls affect the signals from devic-
es plugged into the Line/CD and Mic inputs.
The signal out, to other cabinets, through
the Link will also be affected. These controls
do not affect signals coming into the cabi-
net from the Link connections.
11. Green PWR LED
Illumination indicates that AC power is on and
the fuse is functioning.
12. Yellow Limit LED
This indicates that the cabinet is operating at
full power and the limiter(s) are actively reduc-
ing the signal level. It’s all right to operate in
limiting as long as the clip light is not constantly
on. The Limit light does not indicate low fre-
quency processing action. There are separate
limiters for the woofer and horn. This LED will
indicate operation of either limiter.
13. Red Clip LED
The illumination of this LED indicates that the
signal level is excessive and may cause distor-
tion. Reduce mixer levels or turn down the Level
control (on NX55P) to reduce clipping.
14. Power Switch
This turns the power On and Off to the cabi-
net. Note; a cabinet that is turned off, but is
one of the cabinets in a chain might cause
hum (or buzz) in the other cabinets.
15. 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 re-setting thermal switches are
built into the power transformer as well as on
the internal heat sink. These will not trip even
under the most extreme operating condi-
tions and are provided only for safety reasons.
Thermal margins may be compromised when
operating facing straight up, straight down or
while operating in direct sunlight!
A note about unbalanced operation: When
connecting an unbalanced source (such as a mixer
with RCA outputs) to balanced inputs such as an
NX55P, 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 does not connect the AC power ground
directly to the input signal ground. This will eliminate
most ground problems.
