(24)POWER

SWITCH

Turns the unit ON or OFF. Always turn level controls down before turning on the unit.

(25)VOLTAGE SELECTOR SWITCH For selecting the proper voltage (115/ 230VAC) to match the power supply in your area.

Note: To avoid damage to your unit, always make sure this switch is set to the correct supply voltage. Damage caused by improper use is not covered by the warranty.

(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.
