The Peavey® SP®4P is a powered, bi-amplified, two-way speaker system engineered to provide very high levels of performance in a compact powered loudspeaker. This quasi-three-way powered system is comprised of a 1000 W peak switching power amplifier driving a pair of 15” Black Widow® BWX series woofers, now with a long throw voice coil. The 2” RX™22CT titanium diaphragm compression driver is driven by a 500 W peak switching power amplifier, and is coupled to a low coloration waveguide with a coverage pattern of 100° horizontal by 50° vertical.

The SP®4P is capable of up to 131 dB peak SPL. The enclosure is constructed of plywood augmented with internal braces, covered with a textured black painted finish. The shape is a trapezoidal form, with a full-length coated perforated steel grille, to offer an attractive yet durable powered speaker system. A pair of four-way inset handles, one on each side, and a set of casters on the bottom rear edge and a top rear handle provide convenient transport and handling. Multiple fly points are provided to allow overhead rigging. The cabinet and grille are black.

Two independent mixed input channels each offer a balanced input to the preamp/EQ electronics, and a level control. Each channel has one combo female XLR and 1/4” TRS phone jack. It is switchable between mic-level and line-level sensitivity. Channel 2 has a 3.5 mm media jack added. A line out section has male XLR connec tors. The Thru outputs allow linking of additional speaker systems, or feed of the signal to a powered subwoofer, etc.

The power amplifiers providing the bi-amplification are low-distortion switching units providing 1000 W peak available power into the nominal 4 ohm load of the woofer, and a 500 W peak available power into the nominal 8 ohm load of the tweeter. The power supply for both amps is a switch mode type for low weight and high efficien cy. Both amplifiers feature our DDT™ compression, which virtually eliminates audible power amplifier clipping. Cooling is via forced air circulation. The combination of the Black Widow® BWX woofer with the RX™22CT tweeter and DSP crossover and EQ pro vide a clarity and impact beyond conventional powered enclosures. The switching power amps and switch-mode power supply, along with the professional grade speaker components, provide this high level of technological sophistication at a very light weight, while at a very reasonable cost.




The Peavey® SP®4P has a variety of applications such as sound reinforcement, public address, side fill system, karaoke or musical playback. A typical signal source for the line-level inputs of the Peavey SP®4P would be a sound reinforcement mixing console (mixer) or the output from a CD player, MP3 player or tape deck. A dynamic microphone can be connected directly and used as well.

Bottom Rear Panel


) This rocker switch supplies AC power to the SP®4P when switched to the ON position. The ON position is with the top side of the switch pushed “in” or nearly flush with the rear panel.

FUSE (2)

The unit is AC power line fuse protected from overloads and fault conditions with a slow-blow 5 x 20mm 250V fuse. This fuse is located within the cap of the fuse holder. If the fuse fails, THE FUSE MUST BE REPLACED WITH THE SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT AND TO PREVENT VOIDING THE WARRANTY! The fuse in the SP®4P can be replaced with a time-delay type 5 x 20 mm size 250V rated fuse.

For 120VAC operation, a fuse rated at 10 amps should be used. In the USA, types GDC, GMC, 215, 218, and 477 cartridge-style 5 x 20 mm size fuses with a 10 amp 250V rating can be used.

For 220-240VAC operation, a fuse rated at 5 amps and 250V should be used, which conforms to the international fuse classification “T5AH”. If the unit continues to blow replacement fuses, do not keep replacing them, it should be taken to a qualified service center for repair.

To replace the fuse, be sure to remove the IEC power cord from the IEC socket.


This receptacle is for the IEC line cord (supplied) that provides AC power to the unit. It is very important that you ensure the SP®4P has the proper AC line voltage supplied. You can set the proper voltage for your SP®4P using the Voltage Selector switch (4) on the rear panel of the unit.

Please read this guide carefully to ensure your personal safety as well as the safety of your equipment. 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 grounded properly. To prevent the risk of shock or fire hazard, always be sure that the mixer and all other associated equipment are properly grounded.



The SP®4P has a voltage selector switch to allow switching between an input power voltage of 120VAC to a range from 220VAC to 240VAC, all at either 50 or 60 cycles per second (Hz). It should be set to the proper voltage for your country out of the box. However, world conditions are such that some areas have power line voltages differing from the voltage used by the majority of any given locale. Be sure to check the position of the voltage selector switch to see that it matches the power line voltage used locally. If it does not match, then to change the voltage to the correct one, follow the steps outlined on the next

Changing the Voltage Range of the SP®4P

First, make sure the SP®4P is disconnected from the power line, and that the power switch (1) is in the OFF position.

Second, unscrew the screws holding the clear switch protector on the voltage selector switch (4) just a little, just enough to allow rotation of the clear switch protector. The screws DO NOT need to be unscrewed very far.

Third, rotate the clear plastic protector about 90 degrees to uncover the voltage selector switch. One side of the cover has a slot, the other just a hole, the side with the hole is the side that pivots.

Fourth, using a small flat blade screwdriver, push the red selector switch slide plate to the other side from where it was. The voltage that is now visible on the red slide plate is the one you have selected.

Fifth, rotate the clear plastic protector back underneath the loosened screws, and tighten one down while holding the clear plastic protector in place. Tighten the other screw down, and make sure both screws are tight.

If the screws are over-tightened, this could damage the voltage selector switch clear plastic cover, so do not apply excessive force to the screws!

Sixth, the fuse should be changed to the correct amperage rating. For an input power voltage of 120VAC, use a 10 amp rated, 250V 5 x 20 mm cartridge type time-delay fuse, which conforms to the international fuse classification “T10AH”.

For an input power voltage range of from 220VAC to 240VAC, use a 5 amp rated, 250V 5 x 20 mm cartridge type time-delay fuse, which conforms to the international fuse classification “T5AH”. The IEC power cord that is correct for your locale can now be plugged into the IEC receptacle (3), and the Power switch (1) activated to turn on the powered SP®4P speaker system.

Safety Information


The unit must be disconnected from the AC power source before any work is done on it. Refer all servicing to qualified service personnel.

The back plate can become hot to the touch. Do not block or cover the fan or the exhaust louvers from ventilation. There must be a minimum of 4” of space behind the fan. Do not allow the airflow to be become blocked by objects such as curtains or drapes, thermal building insulation, etc. It is recommended that the rear of the SP®4P not be placed in a closed space or a space that has no fresh, cool airflow.

Be sure to keep the microphone away from the front of the speaker after connecting it to the input, and while setting the microphone level, or very loud feedback will occur! Damage to the system is likely if this occurs!

DO NOT connect the inputs of the SP®4P to the output of a power amplifier. The inputs are meant to be driven from a line-level strength signal.

DO NOT remove the protective metal grille.

WARNING! The SP®4P is very efficient and powerful! This sound system can permanently damage hearing! Use extreme care setting the overall maximum loudness!

The apparent sound level of the SP®4P can be deceiving due to its clear, clean sound output. The lack of distortion or obvious distress can make the sound level seem much lower than it actually is. This system is capable of SPL in excess of 131 dB at 1 M from the speaker!

Flying/Rigging Information

Caution: Before attempting to suspend this speaker, consult a certified structural engineer. Speaker can fall from improper suspension, resulting in serious injury and property damage. Do not suspend or mount any other product or device from this enclosure! Maximum enclosure angle 30°. Use only the correct mat ing hardware. All associated rigging is the responsibility of others.

Whenever possible, in addition to the nominal primary mounting method, use a suitable safety chain or wire rope, attached to one of the other groups of inserts, and firmly attached to a suitable structural member as indi cated by a certified structural engineer.

We recommend the use of Thread-locker at the insert point bolts, so the bolts cannot vibrate loose. Never transport the cabinet using the array bracket or other mounting brackets as a structural member, while the cabinet is mounted on an array bracket or other mounting bracket and unsupported otherwise, as this may unduly stress the mounting inserts.

This Peavey loudspeaker should be suspended overhead only in accordance with the procedures and limita tions specified in the User’s Manual and possible manual update notices. This system should be suspended with certified rigging hardware by an authorized rigging professional and in compliance with local, state and federal suspension ordinances.

WARNING! (note to structural engineer)

NOTE: Use the correct type and grade of bolt into the mounting point inserts. The correct mounting bolt diameter and thread spacing are: M8, 1.25 mm per thread. Use of a metric grade 8.8 bolt or better is recom-

Hardware for Flying/Rigging the SP®4P

Eyebolts or bracket bolts should be M8 metric thread, 1.25 mm per thread.

Eyebolts and bracket bolts must conform to certain minimum strength criteria for safety reasons.

Unspecified eyebolts found at local hardware stores are not strong enough to maintain safety for overhead flying or rigging. Use only forged steel shoulder machinery eyebolts designed for rigging use, which adhere to the stat ed standards as outlined below.

Hardware Specifications

Forged shoulder machinery eyebolts should be an M8 size, 1.25 mm per thread, and must conform to DIN 580 or ASTM A489, for Germany, BGV-C1 is the relevant standard. Minimum shank length should be 20 mm. The eyebolts should be rated for a minimum of 450 lbs straight pull working load Bolts used on custom mounting brackets must be certified to be a metric grade 8.8 or better.

If there are any questions regarding the proper hardware or practices for safe flying or rigging of the Peavey SP®4P, contact a certified structural engineer, or consult with those local rigging companies who have trained and certified personnel.


Connecting AC Power To The SP®4P

When installing the SP®4P, AC power runs will be used and a certified electrician should be consulted to be sure that all AC wiring complies with local codes and regulations. It is also advisable to use a cable clip properly affixed to the cabinet to strain relief the IEC power cord connected to the amplifier module at (3) so the power cord cannot be pulled out or vibrate loose.

Special Note for Permanent Installation

When installing the SP®4P, AC power runs will be used and a certified electrician should be consulted to be sure that all AC wiring complies with local codes and regulations. It is also advisable to use a cable clip properly affixed to the cabinet to strain relief the IEC power cord connected to the amplifier module at (3) so the power cord cannot be pulled out or vibrate loose.

Use of the SP®4P on a Stage or on top of a Subwoofer

Always place the SP®4P on a flat, level and stable surface, and be sure to secure the Sub so it can not roll or fall off of the stage or sub. The SP®118P Sub or SP®218P Sub can be used with an SP®4P using the electrical crossover supplied with the Sub.

Connecting a Signal to the SP™4P

There are a variety of ways to input a signal to the SP®4P. The inputs (5) provides either a balanced mic- or line-level input, allowing the use of a 1/4” TRS (ring-tip-sleeve) type phone plug or a male XLR plug.

There is also a 3.5 mm MEDIA IN jack on the Channel 2 input.

The 3.5mm TRS input jack has its own preamp designed for connection to the headphone jack on mobile audio devices. The Channel 2 Gain control adjusts the signal level from all of the channel 2 input connectors. It is pos sible to use both the combo mic or line input and the 3.5mm input by setting the channel 2 Gain control for the combo input source, and then using the mobile devices headphone volume to adjust its volume.

Note that the 3.5 mm jack mixes a stereo signal down to monophonic, as the SP®4P is a single sound source. Do not connect cables to the jacks while the unit is ON and the Gain knob is turned up! While a standard single-ended 1/4” phone plug-equipped cable will work well and the balanced input circuitry will provide some interference rejection, a balanced cable using either the balanced TRS 1/4” phone plug or the XLR plug will pro vide superior interference rejection and performance. Sometimes, with difficult interference problems, it will be helpful to lift the shield ground ( Pin #1 of an XLR) of a balanced cable at the SP®4P end. Check any input changes carefully, always turning the Gain control down before plugging and unplugging cables, or lifting the ground.

Use of high quality, premium cables is recommended for the SP®4P, as these usually have better shielding and materials and will provide greater long-term reliability. The best option is a shielded balanced cable no longer than necessary to reach the SP®4P. It is usually a good idea to leave some slack at the input to the SP®4P and also to tape the cables down or run them under a cable guard to avoid anyone tripping over them or pulling the SP®4P over when stand mounted.

Gain Control Adjustment

The SP®4P is equipped with Gain controls (6) on the input to facilitate use in many different applications. With the Gain control adjusted fully clockwise, gain is at maximum and the input sensitivity is 0.42 V RMS for full-rated output with the line level position of the Mic/Line switch (7). When driving the SP®4P from a mixer, it may be advantageous to reduce the input sensitivity by turning the Gain control to the halfway point. The SP®4P will now more closely match a typical power amp.

If the mixing board indicates clipping of its output signals, then all of the SP®4P power capability is not being utilized cleanly. Clipping the signal before it gets to the SP®4P is not optimal. Reduce the mixer output level and turn up the Gain control/s on the SP®4P. The amplifiers in the SP®4P are equipped with DDT™ and there is an indication on the rear panel LCD display (12) that reads “DDT” whenever the DDT system engages.

If the sound seems heavily compressed, check this indicator; if it is blinking more than occasionally, then the drive level from the mixer (or the Gain control on the SP™4P) needs to be reduced.

When first turning on the sound system, switch on all upstream electronics first, then the SP®4P with its Gain control fully counterclockwise (all the way down). Begin checking levels with the mixer output level controls all the way down, and bring them up slowly with the SP®4P Gain control/s set to the desired setting (one-third way up recommended to start).

It is not good practice to turn the Gain control/s on the SP®4P all the way up and then try to control level only

from the mixer, this approach would tend to pick up excess noise. Best practice would be to run a “hot” signal from the mixer down the cable to the SP®4P, and then turn the SP®4P Gain control up only as much as necessary to reach full desired output. With this approach, it is necessary to verify the mixer output is not clipping.

Disconnecting AC Power to the SP™4P

We recommend that the Power switch (1) be used to turn the unit off first, and then the AC power cord can be removed, this minimizes stress to the power amplifiers and the transducers from turn-off transients. The power switch has an arc suppression capacitor to help during turn-off, and tends to make a clean disconnect from the AC power, while the power cord IEC connector can make intermittent contact before finally becoming fully disconnected, e.g., as when wiggling the cord.

DSP User Control Menu Operation A two-line, 16-character per line LCD and a rotary push-to-select encoder make up the interface for this prod uct.

The DSP processing control accessible by the user, consists of a 9-band graphic equalizer (GEQ), choice of output Polarity, selection of Bass Enhancement, and signal Delay. This is applied to the powered speaker system, and in some cases, to the processed output. The user can also select from a menu of preset Program EQ settings that are applied to the graphic equalizer and Bass Enhancer. User interface: Rotating the encoder takes the user thru the top level menu screens. These screens will display current infor mation such as a Input Level meter, configuration and current user settings. Pressing the encoder on a top level screen will take the user to related selection screen(s) when relevant. The configuration screens play an im portant role in preparing the speakers for the intended application. The configuration screen comes up after the initialization screen when the speaker is powered on. If the configuration screen is not selected within 5 minutes the Input Level screen is displayed . The user can still select this screen at any time by rotating the edit knob. The configuration screens help the user set up the SP®4P system for optimal operation. By answering a couple of questions, the processor is configured and proper connections displayed. When complete, the user is returned to the main menu. The LCD backlight will dim after 5-minutes without interface activity but returns to full brightness when the encoder is moved. When the backlight auto-dims, the display returns to the Input Level screen. This prevents inadvertent changes from occurring while reactivating the LCD backlight.

No Output at All

First, make sure the unit has AC power and is turned ON. Make sure the LCD on the power amp module is illuminated. If not, make certain the ON/OFF switch (1) is in the ON position and check the IEC power cord connection (3) by ensuring it is fully engaged and seated. Make certain the AC line cord is plugged into a working AC outlet.

Finally, check the fuse (2). (See the Rear Panel: FUSE section, for safety instructions.) Once assured your unit is getting AC power, check that the SP®4P is getting a signal. Temporarily disconnect the cable running to its inputs and connect it to some other device capable of reproducing the signal (i.e., a power amp and speaker). If this produces a signal, make sure that all Level controls being used have been turned up to a satisfactory level (one-third to halfway).

If the SP®4P has been subjected to direct sunlight or excessive heat, the built-in thermal protection may have been triggered. If so, turn off the SP®4P and let it cool for a sufficient amount of time.

If there is still no output, contact your authorized Peavey dealer or the Peavey International Service Center.

Hum or Buzz

If the SP®4P is producing a hum or buzz, this can be AC outlet related. Try plugging the SP®4P into a different AC outlet. Sometimes, if a different circuit (breaker) is used for the mixer and for the SP®4P, it can cause hum problems. Unless it is not practical, it is best to use the same wall outlet (breaker) to supply power to both the mixer and the powered speaker.

Ensure that shielded cables have been used to route the signal to the SP®4P input. If speaker cables with 1/4” plugs are used as input cables instead of shielded cables, they will be prone to hum or buzz.

Hum may be ground loop related. It may be helpful to lift the shield ground (Pin #1) on a balanced cable at the SP®4P end. Check any input changes carefully by first turning down the Level control, before plugging and un plugging cables, or lifting the shield ground at the speaker end.

Check to make sure light dimmers are not on the same circuit as the SP®4P, the mixer or any source devices. If light dimmers are used, then it may be necessary to turn them full ON or full OFF to eliminate or reduce hum. This is a typical AC wiring/light dimmer interference problem, not a design flaw of the SP®4P. The third wire (ground plug) on the AC plug should NEVER be removed or broken off, as this is a potential safety hazard.

Distorted or Fuzzy Sound

First, ensure the mixer (signal source) is not clipping or being overdriven. Make sure the Gain (6) control on the SP®4P has not been set too low. Check that the input plug is fully seated in the input jack on the rear panel of the SP®4P. Ensure that a power amp has not been plugged into the input jack of the SP®4P. If an extension cord is being used to provide the AC power to the unit, insure that it is of sufficient current capacity and that it is not also being used to supply power to any other device. The SP®4P has built-in EQ to smooth and extend the natural response of the speakers. If excessive additional bass boost or HF boost have been added externally to the SP®4P, it could cause premature overload at high SPL. Reduce the amount of any external (mixer, rack) EQ and see if that clears up the distortion.

If no external bass boost or HF boost has been added, but there seems to be an excessive amount of bass boost (boominess, bass clipping, and/or treble boost (shrillness, sizzle, harshness), then you may have selected the wrong choice on the Set-Up Wizard in the DSP menu on the LCD display. Go back and select the proper choice.

If using the SP Sub as the main input from the mixer, and then running a cable from the Sub to the SP®4P , then the SP®4P should be set to USE WITH SP SUB on the Set-Up Wizard menu. If the Set-Up Wizard menu choice seems to be correct, and there is still too much boost, then try a preset with less boost, such as the Acoustic (Flat) preset and make sure the Tone controls have not been set all the way up.

Finally, realize that even though the SP®4P is a powerful and high output unit, it does ultimately have limits, and it may need additional powered units (or a subwoofer) to provide enough sound output or coverage. In this case, try turning the mixer levels down a little to see if that clears things up. If, after checking all the things listed to check and anything else you can think of to check safely, and the system still exhibits problems, carefully note all conditions and check with your Peavey dealer for advice.

Care and Maintenance

Your SP®4P is a sturdy and durable product and will provide years of reliable use if properly cared for. Use com mon sense and read the safety warnings to avoid hazardous operating conditions.

The unit must be disconnected from the AC power source before any work is done on it. Refer all servicing to qualified service personnel.


Avoid prolonged exposure to direct sunlight, as this may cause the unit to overheat and thermally shut off.

Excessively hot operating conditions can also cause a thermal shutdown.

Do not store in extremely hot or cold conditions or extremely high humidity. Always allow unit to come to room temperature before use.


Never clean the SP®4P while plugged in or turned ON! When the unit has been fully disconnected from AC power sources, use a dry cloth to remove soil or other dirt. Never use strong solvents on the SP®4P, as they could damage the cabinet. Do not allow ANY fluids to drip inside the SP®4P.


To touch up the painted surfaces of the SP®4P, you can use Peavey® Black Touch-Up paint (part # 00052110). Never paint the enclosure or other parts while the unit is plugged in or turned on!

Check for Secure Hardware

After the first few weeks of use and periodically thereafter, check the hardware of the SP®4P for tightness, includ ing the rear panel screws and the screws that hold the baffle and rear cabinet together.

The unit is subject to a great deal of vibration, and this could cause the hardware to loosen with use.
