1.INPUT 1: Use this 1/4” jack to connect your key- board or other line level signal to the amplifier by means of a shielded instrument cable. The signal level at this jack is controlled by the Level 1 knob (#3).
2.INPUT 2: Use this 1/4” jack to connect your key- board or other line level signal to the amplifier by means of a shielded instrument cable. The signal level at this jack is controlled by the Level 2 knob (#4).
3.LEVEL 1: Use this control to adjust the level of the signal connected to the Input 1 jack (#1).
4.LEVEL 2: Use this control to adjust the level of the signal connected to the Input 2 jack (#2).
5.PEAK: This LED illuminates when the input signal level nears clipping. For the best signal to noise ratio, adjust the Level controls until this LED flashes on strong signal peaks.
6.LOW: Use this control to adjust the bass response of the amplifier. Rotating the control counterclockwise reduces the low frequency output. Rotating the con- trol clockwise increases the low frequency output.
7.LO MID: Use this control to adjust the “thickness” or “fatness” of the amplifier. Rotating the control coun- terclockwise reduces the lower midrange frequency output. Rotating the control clockwise increases the lower midrange frequency output.
8.HI MID: Use this control to adjust the clarity and definition of the amplifier. Rotating the control coun- terclockwise reduces the upper midrange frequency output. Rotating the control clockwise increases the upper midrange frequency output.
9.HIGH: Use this control to adjust the high frequency response of the amplifier. Rotating the control coun- terclockwise reduces the high frequency output. Rotating the control clockwise increases the high fre- quency output.
10.REVERB: Use this control to adjust the amount of reverberation added to the signal. With the control fully counter clockwise, the signal is dry - no reverb added. As you rotate the control clockwise the amount of reverb added increases.
11.LEVEL: Use this control to adjust the overall out- put signal of the amplifier.
12.LIMIT: The KXB50 employs an internal limiter cir- cuit to help prevent overdriving the output signal. This LED illuminates when the limiter circuit is activated. During normal playing conditions, this LED will flash occasionally. If this LED remains illuminated, reduce the level controls.
13.CD INPUT: Use these RCA jacks to connect the output from a CD player or tape deck to the amplifier. The signal at these jacks is combined into a mono sig- nal which is sent to the internal power amp circuit. Use the CD or tape player’s output level control to adjust the signal for the proper mix with your instru- ment.
14.INSERT: Use this jack to connect external effects to the amplifier. This is a stereo R/T/S 1/4” jack: ring = line out, tip = line in, sleeve = ground. This jack can also provide a line out signal - insert a mono T/S 1/4” plug half way into the jack to obtain the signal. (This will not interrupt the signal going into the internal power amp.)
15.
(HEADPHONES): Use this jack to connect headphones to the amplifier. The internal speakers are disconnected when this jack is used.
CAUTION: To avoid possible damage to your hearing, do not use headphones for extended periods of time at extremely loud levels.
16.ON: This LED illuminates when the amplifier is turned on.
17.POWER: Use this switch to turn the amplifier on (top of the switch depressed) and off (bottom of the switch depressed).
18.POWER CORD (rear panel, not shown): The grounded power cord should only be plugged into a grounded power outlet that meets all applicable elec- trical codes and is compatible with the voltage, power, and frequency requirements stated on the rear panel.
Do not attempt to defeat the safety ground con- nection.
