Level Control
The Main level control sets the level of all sound
coming out of the NX250P enclosure. Unlike the
Mic Gain control, this control does not affect
the signal coming out the Mix Out. In systems
using multiple NX250P enclosures the Level
control on each cabinet sets the volume for
that cabinet. When used with a microphone
connected to one NX250P at the beginning
of the chain the Level control will normally be
set to maximum unless it
is desired that a particular
cabinet be set quieter
than the rest. When a
line source is used the
Level control will set the
volume for the enclosure. If
there are multiple NX250P
enclosures in a system, it
will be necessary to set
the Levels separately. If
using a mixer for the line
source, the mixer should
control the level of all
the NX250P enclosures.
(When a mixer drives the
NX250P enclosures, the
Level control should be set
to maximum). If there are
multiple NX250P enclosures
it may be desirable to
set the level control of
individual enclosures to
less than maximum (if it’s
desirable for that enclosure
to be quieter).
Treble, Mid and
Bass Controls
These controls affect all the sound coming
out of a particular NX250P enclosure. These
controls do not affect the sound at the Mix
Out. In a system with multiple cabinets it will
be necessary to adjust the bass, Treble, Mid
and Bass controls on all individual enclosures.
Signal / Limit LED
This dual LED illuminates green when signal is
present and red when limiting.
Shield Switch
The Shield switch disconnects the ground
connection on the Line In. This may help
prevent hum or buzz under
some circumstances.
Power LED and
Switch
The Power Switch turns the
power on and off for the
NX250P enclosure, the green
LED will illuminate when the
power is on also indicating a
properly functioning fuse.
Voltage Selector
Switch
Select the proper voltage
for the geographical region
in which the NX250P will
be used. The unit is set for
115V when used with the
standard North American
line voltage. For European
operation set the unit to
230V. If in doubt of the line
voltage please contact your
local Yorkville dealer.
