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 Safety 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
2100
1 1⁄2 102
1105
1⁄2 110
1⁄4 or 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.

Congratulations on your purchase of the Peavey MAX®450. The MAX 450 includes an easy-to-use, threeband active EQ with shiftable mid-range control and a contour control (for that smiley-face EQ curve).
These tone controls are so versatile you should be able to quickly dial up your own sound.
Also provided are a buffered tuner send jack, an electronically balanced XLR line out with its own level
control, pre-post EQ switch, and a ground lift switch. The XLR output is before the master volume control,
so you can adjust your stage volume without affecting the send to the main sound system.
A -10 dB input pad switch, footswitchable post-EQ effects loop, preamp output/power amp input patch
points, and the DDT
™
(speaker protection) enable/defeat switch add to the list of professional features
found in the MAX 450.
For more information on operation and specifications we suggest that you spend a few minutes to look
through this manual. Pay close attention to the safety precautions. They contain warnings that concern
the safety of both you and your amp. Thank you for buying Peavey!

This receptacle is for the IEC line cord (included), which provides AC power to the unit. Connect the line cord to
this connector and to a properly grounded AC supply. Damage to the equipment may occur if an improper line
voltage is used. (See voltage marking on unit.) Never remove or cut the ground pin of the line cord plug. This unit
is supplied with a properly rated line cord. When lost or damaged, replace this cord with one of the proper
ratings.

As the colors of the wires in the mains lead of this apparatus may not correspond with the colored markings
identifying the terminals in your plug, proceed as follows: (1) The wire which is colored green and yellow must be
connected to the terminal which is marked by the letter E, or by the earth symbol, or colored green or green and
yellow. (2) The wire which is colored blue must be connected to the terminal which is marked with the letter N, or
the color black. (3) The wire which is colored brown must be connected to the terminal which is marked with the
letter L or color red.

Three-position, rocker-type switch, which for most applications should be operated in the center (zero) position. If
hum or noise is present with the ground switch in the center position, place the ground polarity switch to positive
or negative (+ or -) to minimize hum; should a problem continue, consult your authorized Peavey dealer, the
Peavey factory, or a qualified service technician.

Located on front panel this LED illuminates green when the Power Switch is in the “ON” position and AC power is
supplied. During normal operation the LED also acts as a DDT indicator. The LED illuminates red when the DDT
speaker protection is active. When DDT is defeated, the LED will illuminate red when clipping occurs.

This jack accommodates the remote footswitch (optional part number 00051000 ON/OFF single button switch),
which is used to remove the effects loop from the signal path. The remote footswitch essentially acts as a bypass
to punch in or punch out from your external effects.

DDT™ speaker protection is defeated when the push button is in the “in” position. We recommend that DDT be
enabled at all times to protect the speakers.

This 1/4" jack is used to route the preamp signal to external inputs, such as the input of an additional power amp.
The signal is post volume control. Use of this jack does not defeat the signal to the MAX 450 amp (some volume
difference may be noticed due to the impedance change experienced when adding an external unit to the signal
patch).
2266.. PPOOWWEERR AAMMPP IINN JJAACCKK
This 1/4" jack is used to input an external signal to the power amp section of the MAX 450. Using this jack will
disconnect any signal from the preamp section. Using this jack along with the preamp out jack creates a possible
second effects loop.
2277.. PPOOWWEERR CCOORRDD RREETTAAIINNEERRSS
Use the Power Cord Retainers to wrap and store your cable while storing or transporting your MAX 450. It is best
to disconnect the cord from the unit before wrapping.
2288.. SSPPEEAAKKEERR OOUUTTPPUUTT JJAACCKKSS
These two 1/4" jacks provide the powered signal from the amplifier. Each connector is electrically the same (in
parallel). Use one of the jacks to connect your speaker cabinet and the other to add a second speaker cabinet in
parallel. The minimum speaker load impedance is 2 Ohms (or two 4-Ohm speakers in parallel).

To prevent the amplifier from overheating, the front fan and rear-located vents should always remain
clear of obstructions.
