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
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.
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).

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
