When using electrical products, basic cautions should always be followed, including the following:
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any of the ventilation openings. Install in accordance with manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers)
that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one
wider than the other. A grounding type plug has two blades and a third grounding plug. The wide blade or third prong is
provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the
obsolete outlet.
10. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point
they exit from the apparatus.
11. Note for UK only: If the colors of the wires in the mains lead of this unit do not correspond with the terminals in your
plug‚ proceed as follows:
a) The wire that is colored green and yellow must be connected to the terminal that is marked by the letter E‚ the earth
symbol‚ colored green or colored green and yellow.
b) The wire that is colored blue must be connected to the terminal that is marked with the letter N or the color black.
c) The wire that is colored brown must be connected to the terminal that is marked with the letter L or the color red.
12. Only use attachments/accessories provided by the manufacturer.
13. Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a
cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
14. Unplug this apparatus during lightning storms or when unused for long periods of time.
15. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any
way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus,
the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
16. Never break off the ground pin. Write for our free booklet “Shock Hazard and Grounding.” Connect only to a power
supply of the type marked on the unit adjacent to the power supply cord.
17. If this product is to be mounted in an equipment rack, rear support should be provided.
18. Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise
for a sufficient time. The U.S. Government’s Occupational and Health Administration (OSHA) has specified the following
permissible noise level exposures:
Duration Per Day In Hours Sound Level dBA, Slow Response
890
692
495
397
2 100
1 1⁄
2
102
1 105

⁄4or less 115
According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear plugs or protectors to the
ear canals or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss, if exposure
is in excess of the limits as set forth above. To ensure against potentially dangerous exposure to high sound pressure levels, it is
recommended that all persons exposed to equipment capable of producing high sound pressure levels such as this amplification system be
protected by hearing protectors while this unit is in operation.

Keyboard Amplifiers
Thank you for selecting the KB4/KB5 keyboard amplifier. Once again‚ Peavey engineers have listened to input from
keyboard players and put together an amplifier that combines excellent features and sound in one portable package. The
new KB Series amplifiers deliver awesome sound reproduction for all of your keyboard sounds—from thundering bass to
crystal highs—it’s all there!
Before you begin to play through your amp, it is very important to ensure the product has the proper AC line voltage
supplied. You can find the proper voltage for your amp printed next to the IEC line (power) cord on the rear panel of the
unit. In addition, an external speaker jack is provided for the additional use of an external speaker enclosure. This
feature is located on the rear panel as well and is also explained in this section. Each product feature is numbered. Refer
to the front and rear panel diagrams in this manual to locate the particular features next to their number.
Please read this guide carefully to ensure your personal safety as well as the safety of your amplifier.

Caution: Excessive low frequency boost causes greater power consumption and increases the
possibility of speaker damage.

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.

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.
MMaasstteerr LLeevveell ((1100))
This knob sets the overall level for the unit. Make sure the Master level is completely down (full counterclockwise) before powering up the unit. This does not affect the headphone level.
DDDDTT™™SSeelleeccttoorr ((1111))
This switch controls Peavey’s exclusive DDT (Distortion Detection Technique) speaker protection. With
this switch in the OUT position‚ a unique circuit senses signal conditions that might overload the
amplifier and activates compression to reduce gain and avoid clipping. This technique utilizes every watt
available for the amplifier to reproduce the signal‚ yet minimizes clipping and distortion which reduces
the potential for speaker damage. Since this function is “invisible” at levels below the clipping point‚ it is
advised that it be activated at all times. Setting this switch to the IN position defeats this protection
feature‚ allowing potential power amp clipping and the resultant increase in likelihood of speaker
damage.

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.

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.

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.
