(1)Level  - Controls the 1⁄4" jack input level. (Channels 1‚ 2 and 3 on the KB5 and channels 1 and 2 on the KB4.)

(2) Low EQ - An active tone control (shelving type: +/-15dB) that varies the low frequency range. (KB5: channels 1‚ 2 & 3; KB4: channels 1 & 2.)

(3) Hi EQ - An active tone control (shelving type: +/-15dB) that varies the hi frequency range. (KB5: channels 1‚ 2 & 3;KB4: channels 1 & 2.)

(4) High Z Level - Controls the high-impedance microphones or other high-level sources equipped with a 1⁄4" phone plug.

(5)Low Z Level  - Controls the low-impedance microphones or other low-level sources equipped with a male XLR connector

(6)Mid EQ  - An active tone control (peak/notch type: +/-15dB) that varies the mid frequencies. (Channel 4 on the KB5 and channel 3 on the KB4.)

(7) Main/Monitor - This affects what signal is sent to the headphones. When in the OUT position‚ only the signal from channel 5 is sent to the headphones. Great when you need to hear a click track or midi/pre-recorded track. When engaged (IN position)‚ the headphones are sent signals from all channels. Keep in mind‚ this signal is never sent to the Main XLR outs.

(8) CH5/Monitor Level - Controls the input level for channel 5. Controls high-impedance microphones or other high-level sources equipped with a 1/4" phone plug.

(9)Headphone Level - This sets the level to the headphone jack on the rear panel. To avoid damage to your hearing‚ make sure to turn the dial fully counter-clockwise before using headphones. Slowly turn the knob clockwise until a comfortable listening level is set. This does not affect the master level

(10)Master Level – This knob sets the overall level for the unit

(11)DDT Selector- This switch control Peaveys exclusive (Distortion Detection Technique) speaker protection

(12) Power Switch – This two way rocker switch applies power to the unit when placed in the ON position

Rear Panel Features:

(1) Ground Polarity - This 3-position‚ rocker-type switch should normally be placed in the center (0) position. If hum or noise is noticed coming from the speaker enclosure‚ the switch may be placed in the (+) or (-) position to minimize hum/noise. If changing polarity does not alleviate the problem‚ consult your authorized Peavey dealer‚ the Peavey factory or a qualified service technician.

(2) Main Line Out - These low-noise‚ electronically balanced XLR connectors can be used to route signals to a mixing console‚ recording device‚ etc.

(3 & 4) Send/Return Jacks Mains  - Two stereo pairs of 1/4" jacks allows the use of various auxiliary units (effects units‚ equalizers‚ etc.) in-line‚ before the power amp section.

(5)Headphone Jack  - This 1/4" jack accepts stereo headphones only.

(6) CH5/Monitor Input Jack  - Use this 1/4" jack to connect to the output of any line-level device.   

(7) Channel 4 (Channel 3 input on KB4) High-Impedance Input  - This pair of 1/4" jacks accepts high-impedance microphones or line-level sources equipped with left and right 1/4" phone plugs.

(8) Channel 4 (Channel 3 input on KB4) Low-Impedance Input - For use with low-impedance microphones or other line-level sources equipped with a male XLR connector.

(9 & 10) Channel 4 (Channel 3 input on KB4) Send/Return Jack  - This pair of 1/4" jacks allows the use of various auxiliary units (effects units‚ equalizers‚ etc.) in-line.

(11‚ 12 & 13) Channel 3‚ 2 & 1 (Channel 2 & 1 on KB4) Inputs  - This pair of 1/4" jacks accepts high-impedance microphones or line-level sources equipped with leftand right 1/4" phone plugs.

(14) External Speaker Jack  - This 1/4" jack provides the powered signal from the amplifier. Use this jack to add a second speakercabinet in parallel. The external minimum speaker load impedance is 8 ohms.

(15) IEC connector/detachable line cord  - 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.
