This does not affect the headphone level. (8) Power Switch This two-way rocker switch applies power to the unit when placed in the ON position. F R O N T P A N E L 1 5 6 2 3 4 7 8 6 R E A R P A N E L Main Line Out (9) This low-noise‚ electronically-balanced XLR connector can be used to route signals to a mixing console‚ recording device‚ etc. Send/Return Jacks Mains (10 & 11) This pair of 1/4" jacks allow the use of various auxiliary units (effects units‚ equalizers‚ etc.) in-line‚ before the power amp section. Headphone Jack (12) This 1/4" jack accepts stereo headphones only. CH4/Monitor Input Jack (13) Use this 1/4" jack to connect to the output of any line-level device. Channel: 3 Low-Impedance Input (14) For use with low-impedance microphones or other line-level sources equipped with a male XLR connector. Channels 3‚ 2 & 1 (15) These 1/4" jacks accept high-impedance microphones or line-level sources equipped with 1.4" phone plugs. External Speaker Jack (16) (KB3 only) This 1/4" jack provides the powered signal from the amplifier. Use this jack to add a second speaker cabinet in parallel. The external minimum speaker load impedance is 8 ohms. IEC connector/detachable line cord (17) This is a standard IEC power connector. An AC mains cord having the appropriate AC plug and ratings for the intended operating voltage is included in the carton. The mains cord should be connected to the amplifier before connecting to a suitable AC outlet. U.S. Domestic AC Mains Cord The mains cord supplied with the unit is heavy-duty‚ 3-conductor type with a conventional 120 VAC plug with ground pin. Never break off the ground pin on any equipment. It is provided for your safety. If the outlet used does not have a ground pin‚ a suitable grounding adapter should be used and the third wire should be properly grounded. 17 12 9 14 10 11 13 15 16 K KKB BB2 22/ //3 33 B BBl llo ooc cck kk D DDi iia aag ggr rra aam mm 7 K KKB BB® ®®3 33 S SSP PPE EEC CCI IIF FFI IIC CCA AAT TTI IIO OON NNS SS PPRREEAAMMPP SSEECCTTIIOONN The following preamp specs are measured @ 1 kHz‚ nominal signal levels are with channel level controls set at 5‚ minimum levels are with channel level controls set at 10.
