WARNING: Before connecting an NTS loudspeaker to the AC mains supply, completely turn
down the input signal to the loudspeaker using the signal source's output level (master volume
control or other output level control). If not, there could be excessive and possibly damaging
sound levels from the loudspeaker when energized.
3 . 3 A u d i o C o n n e c t i o n
Connect the output from your line-level signal source to the XLR-3F Input connector on the rear panel.
This is an electronically balanced input. Use the loop through connector to daisy-chain the signal to
additional NTS250s.
3 . 4 A C M a i n s C o n n e c t i o n
Connect one of the supplied AC mains cord to the Neutrik PowerCon receptacle on the rear of the
loudspeaker. Use the appropriate cord for the AC mains voltage as labeled on the loudspeaker: nominal
115 V or 230 V. Connect the other end to the AC mains supply receptacle. If necessary, have a qualified
electrician change the AC mains cord plug as required for compatibility with the local AC mains
receptacle.
CAUTION: There is no power switch on the loudspeaker. When connected to the AC mains,
the loudspeaker will be fully operational, with the output level controlled by the signal
source feeding the loudspeaker.
3 . 5 A d j u s t i n g t h e O u t p u t L e v e l
With a source program playing, gradually turn up the level of your signal source until the desired
volume is reached but below the point where the CLIP and/or LIMITER lights illuminate.
CAUTION:
If there is no sound, turn down the signal source's output level before
investigating the problem. Do this to avoid excessive and possibly damaging sound levels
from the loudspeaker.
