up to 300 watts of power with Peavey’s DDT™ speaker protection and exclusive tone enhancements.
The Peavey MAX 100, MAX 150, MAX 208, MAX 250, and MAX 300 bass combo amps deliver huge bass tone with exclusive
Peavey designs, including unique psycho-acoustic low-end enhancement that adds bass without demanding anything extra from the
speaker—a testament to Peavey's technology-driven reliability. The EQ section includes three-band EQ, a gain boost featuring Peavey’s
patented TransTube® tube emulation circuitry, and switchable presets like Contour, Mid-Shift and Bright.
The MAX 100, MAX 150, MAX 250, and MAX 300 also feature a built-in chromatic tuner with mute, a tuned and ported enclosure,
1/8" headphone output and 1/8" auxiliary input. All models include an XLR direct output with ground lift, while the MAX 250 also
has a built-in tweeter.
Features: (vary according to model)
• Up to 300 watts of power
• Premium speakers
• DDT™ speaker protection
• Pre-gain control with TransTube® gain boost
• ree-band EQ with Overdrive, Contour, Mid-Shi, Bright, and Kosmos-C switches
• Tuned, ported enclosures
• Kosmos-C low-end enhancement
• Precision balanced direct interface with ground li
• 1/8" aux input

• Chromatic tuner with mute (not on 208)
• Unique cabinet design allows for superior high-frequency dispersion in tight spaces.
VENTILATION: For proper ventilation, allow 12" clearance from the nearest combustible surface.
All vents should have a minimum of 2" of free air space so air can flow thru the unit freely for proper cooling.

(1) ACTIVE/PASSIVE PICKUP Inputs
ese 1/4" inputs are included so you can choose the appropriate setting for your instrument. e gain structure of the amplier is
modied to accommodate the outputs of dierent pickup congurations. e PASSIVE input is 10dB hotter than the ACTIVE input.
(2) GAIN
is knob controls input level to the preamp.
(3) OVERDRIVE
is crunch circuit is designed so that the volume of the amp will not change when the boost is switched on, but the distortion level
will increase depending on the level of the GAIN knob. For best results, rst set the distortion amount by adjusting the GAIN. Next,
set the desired volume using the VOLUME knob. At this point, the clean volume will match if the Overdrive is turned o.
(4) BASS
is knob provides a shelving tone control for low frequencies and provides cut/boost of +/-15 dB. e center point is at. e center
frequency is 50 Hz. -3 dB shelf corner frequency is 100Hz.
(5) CONTOUR
is button boosts highs and lows while simultaneously cutting mid tones, producing a "scooped" sound.
(6) MIDDLE
is knob provides a peaking tone control for Mid frequencies and cut/boost of +/-15dB. e center point is at.
(7) MID SHIFT
is switch controls the center frequency of the MIDDLE knob. When the switch is OUT, the middle frequency is 600Hz. e middle
frequency is 250Hz when the switch is pushed IN.
(8) TREBLE
is knob provides a shelving tone control for high frequencies and cut/boost of +/-15dB. e center point is at and the frequency is
6 KHz. -3dB; the shelf corner frequency is 4 KHz.
(9) BRIGHT SWITCH
is button provides a 10 dB boost to frequencies above 1KHz. To activate, depress the switch to its “IN” position.
(10) VOLUME
is knob controls the overall volume of the amplier.
(11) KOSMOS-C Subharmonic Generator
is Kosmos-C Low enhancement works by creating harmonics of signals in the bottom octave, where speakers are usually ineective. e harmonics are more easily reproduced, resulting in a perception of stronger bass. e eect is source dependent; obviously a
source with little energy in the bottom octave will not create booming bass.
(12) CHROMATIC TUNER (Not on Max 208)
Pressing the TUNE/MUTE button (13) will engage the chromatic tuner while muting the output to the speaker. e LED screen will
indicate which note is being played while the red and green LEDs above the screen indicate whether the note is at (red), sharp
(red) or in tune (green).
(13) TUNE/MUTE (not available on Max 208)
Pressing this button will engage the chromatic tuner while muting the output to the speaker. e LED screen will indicate which note
is being played while the red and green LEDs above the screen indicate whether the note is at (red), sharp (red) or in tune (green).
is switch also mutes the DI.

(15) AC POWER INLET:
is is the receptacle for an IEC line cord, which provides AC power to the unit. Connect the line cord to this connector to provide
power to the unit. Damage to the equipment may result if improper line voltage is used. (See line voltage marking on unit).
Never break o 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 grounded properly. To prevent the risk of shock or re hazard, always
make sure that the amplier and all associated equipment is properly grounded.
NOTE: FOR UK ONLY
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) e wire that is colored green and yellow must be connected to the terminal that is marked by
the letter E, or by the Earth symbol, or colored green or green and yellow. (2) e wire that is colored blue must be connected to the
terminal that is marked with the letter N, or the color black. (3) e wire that is colored brown must be connected to the terminal that
is marked with the letter L, or the color red.
(16) LINE VOLTAGE SELECT SWITCH
is selector switch allows the amplier to be operated at dierent line voltages. Please be sure this switch is set to the
proper voltage for your area before connecting the amplier to a power source or turning the amplier on for the rst time.
NEVER CHANGE THE POSITION OF THIS SWITCH WHILE THE AMPLIFIER IS TURNED ON.
CAUTION! THE FUSE MUST BE CHANGED TO THE CORRECT VALUE PRINTED ON THE REAR OF THE CHASSIS IF
A DIFFERENT LINE VOLTAGE IS SELECTED.
(17) SPEAKER OUTPUT JACK (Max 150, 250, and 300 only)
is combination 1/4" / twist-lock connector is used to connect a speaker cable to the amplier. e minimum load impedance on the
amplier is 8Ω.
(18) FOOTSWITCH JACK
e optional footswitch (part number 03022910) plugs into this jack. e footswitch controls OVERDRIVE and MUTE.
(19) HEADPHONE OUTPUT
1/8" headphone output for personal monitoring.
(20) AUX INPUT
is 1/8" input jack allows you to connect a CD player or MP3 player to your MAX® Series bass amp and play along
(21) PRECISION BALANCED DIRECT INTERFACE
is XLR output is used to connect the Max pre amp section to external equipment, such as mixing consoles, external power ampliers,
or recording equipment. is novel circuit provides a perfectly balanced and noise-free signal with none of the problems associated
with small transformers.
(22) DI GND LIFT SWITCH
is switch may be used to eliminate hum caused by ground loops between the amplier and other equipment, such as a mixing console.
(23) FX LOOP
e eects loop consists of the SEND and RETURN jacks, which are used to patch external eects processors post EQ in the signal
chain. Connect the SEND jack to the input of eects processors. Connect the RETURN jack to the output of eects processors. e EFFECTS SEND and RETURN jacks can also be used as a line level unbalanced preamp output and power amp input jacks, respectively.
