(26) POWER CONNECTOR WITH FUSE HOLDER
This standard IEC power cord receptacle is used to
connect the AC power to your unit. It features a built-in fuse
holder for a 5X20mm, (4A/250V for 115VAC, and 2A/250V
for 230VAC operation) fast-blow fuse. If the fuse
continuously blows, shut off the unit and have it serviced by
qualified service personnel.
(27) SPEAKER OUTPUTS
Two 1/4" (6.3mm) jacks, each powered by its own separate
amplifier output stage, for connecting left and right speaker
cabinets. The connected speaker impedance must be 4
ohms or greater. The PA-4180 delivers 90W RMS of power
@ 4 Ohms per each speaker output.
CAUTION: Do not overload the ENSEMBLE PA 4180 with
speaker loads less than 4 ohms as this will degrade
performance and may harm the unit. Damage caused by
improper use is not covered by the warranty.
