[. . . ] CARVIN ENGINEERING DATA KB1000 HEAD/KB1010 COMBO/KB1015 COMBO OPERATING MANUAL KB1000 Congratulations on your purchase of the KB1000 series amp. The KB1000 combines a 7-channel stereo line mixer, 4-band EQ, Direct Out box and a stereo / bi-ampable power amp with crossover into one compact package. Your new amp inherits Carvin's rugged DCM power amp technology with features including power amp limiters, high current SpeakonTM speaker connectors, 1' Titanium Drivers for the KB1010 and the KB1015 combos, and thermal/short circuit protection. This manual covers the KB1000 head the KB1010 and KB1015 combo amplifiers. GETTING STARTED QUICKLY If you are like most players, you probably want to plug in your new amp and get started playing right away. [. . . ] MONO (MAIN) SWITCH With the MONO switch in the "OUT" position, the KB1000 will preserve stereo imaging from the INPUT JACKS to the POWER AMP 1(L) & 2(R) outputs. Setting the MONO switch to the "IN" position will send the combination of both LEFT and RIGHT signals to both POWER AMP OUTPUTS. Helpful if only one speaker cabinet is used, or if stereo imaging is not important. NOTE: THE MONO (MAIN) SWITCH DOES NOT AFFECT THE STEREO OR MONO OUTPUT OF XLR DIRECT OUTS. 4. DIRECT OUT XLRs The DIRECT OUT XLRs are balanced outputs that get their signal directly from INPUTs 1-7. These outputs are very useful when connecting to the main mixing board for live performances or recording. Use the DIRECT OUT LEVEL control to set the output. The MONO switch is used to combine the LEFT and RIGHT INPUTS so that both L-R DIRECT OUT XLR jacks receive the same mono signal. NOTE: THE DIRECT OUT MONO SWITCH DOES NOT AFFECT THE STEREO OR MONO OUTPUT OF THE POWER AMP. A LIFT GND switch is also available on the DIRECT OUT XLR jacks. Set this switch for the lowest hum/noise when using this output. When the LIFT GND switch is depressed, the signal ground is lifted from these jacks thus eliminating any ground loops between the KB1000 and the gear it's feeding. NOTE: THE AMP EQ, POWER AMP 1&2 AND MAIN LEVEL CONTROLS DO NOT AFFECT THE DIRECT OUT SIGNAL. 10. PHONES JACK A PHONES jack is provided for practicing or monitoring. The phones jack does not interrupt the amplifier output. To listen to the PHONES output without sound from the speakers, turn down the POWER AMP 1&2 controls. A high-current headphone amp drives this output for any pair of headphones. REAR PANEL FEATURES 11. POWER / (RESET) Push the upper portion of the POWER SWITCH to turn the amplifier on. If the POWER LED is on but no sound is coming out of the speakers, the amp may have gone into one of its protection modes with the PROTECT LED ON. To reset the amp, turn the power off for one minute and then turn the amp back on. If the problem persists, check for; a) The speaker impedance is too low for the bridge output (4 ohm min. ) or normal outputs (2 ohms min. per amp) b) bad speaker cable, c) damaged speaker or d) blocked rear fan cooling vents. 5.
