KX-100 Keyboard Amplifier

1:Mic input jack will accept a low impedance balanced input, such as a microphone, and may be used in conjunction with the Line Input (#2).

2:Line input also provides Channel 1 with a 0dB balanced input jack. It is suitable for a signal source from synthesizers.

3:Level controls set the gain for each channel independently.

4:Peak Indicator LEDs light when the corresponding input stages of the each channel are within 10dB of clipping. Adjust each Level control (#3) until a strong signal from the instrument or signal source causes the LED to flash.

5:Reverb/Effects Send controls are used to set the amount of reverb, as well as the amount of signal sent to the Effects Send jack (#17) for each channel.

6:Phantom Power applies 15 volts to the Mic input jack (#1) when this switch is pressed in.

7:Low control increases or decreases the bass response of channel 1.

8:High control increases or decreases the treble response for channel 1.

9:Input jacks for Channels 2, 3 and 4 accept standard 1/4” phone jacks, and are suitable for a line level source such as a signal from synthesizers.

10:Master EQ has five bands and enables you to shape the tonality of the KX-100 to suit room acoustics. Frequencies from 100Hz to 10kHz may be boosted by moving the sliders up or cut by moving them down.

11:Reverb Return acts as the reverb master level control and works with each channel’s Reverb/Effects Send control (#5).

12:Master Level controls the total output level of the KX-100.

13:Effects Return control is a master volume for the Effects Loop (#17 and 18) with which you can increase or decrease the amount of effect desired. This control works with each channel’s Reverb/Effects Send control (#5).

14:Balanced Line Out/Headphones Level adjusts the level for both the Balanced Line Out and Headphones jack and is independent of the Master volume.

15:Power Indicator LED will be lit when the unit is turned on.

16:Power Switch turns the AC power on and off.

17:Effects Loop Send jack, when used in conjunction with the Return jack (#18), provides a pre-EQ effects loop. The pre-EQ circuitry reduces the unwanted noise associated with most external effects devices. This output can be connected to the line input of your external effects device.

18:Effects Loop Return jack can be connected to the line out- put of your external effects device.

19:Preamp Out jack provides a high impedance unbalanced output for connecting the KX-100 to another amplifier or a tape recorder. Simply run a cord from this jack to the input of the other amplifier or the tape deck.

20:Power Amp In jack is used as a direct input to the power amp. Plugging into this jack disconnects the direct (normal) con- nection between the preamp and the power amp. This jack may be used with the Preamp Out jack (#19) as an effects loop.

21:Balanced Line Out jack is a low impedance balanced out- put for connection to an external amplifier or mixer with balanced inputs.

22:Headphones jack allows the use of stereo headphones. Connecting headphones here does not disconnect the internal speakers. For private listening, turn down the Master level con- trol (#12).

23:Power Cord (rear panel, not shown): Your KX-100 is equipped with a heavy-duty grounded three-wire power cord. Be sure this cord is properly plugged into a safely wired grounded 120 volt, 60Hz AC power outlet before use. (If your KX-100 was purchased outside the United States, refer to the rear panel for power ratings.) For your safety, never attempt to defeat the ground connection on this cord.
