WARNING: Before connecting an JFNT/KFNT 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 Audio Connection

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.

3.4 AC Mains Connection

Connect the supplied AC mains cord to the Neutrik PowerCon socket on the rear of the
loudspeaker. Connect the other end to an AC mains supply receptacle, nominal 115 V 60 Hz or 230
V 50 Hz as labeled on the loudspeaker. If necessary, have a qualified electrician change the cable
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 Adjusting the Output Level

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 ACTIVE 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.
