The unit is AC power line circuit breaker protected from
overloads and fault conditions with a resettable 8 Amp breaker.
If this unit trips the breaker, turn the power switch to the OFF
position, reset the breaker by pushing the center lever in all the
way and then reactivate the power switch. If the breaker lever
does not stay in, it may need to cool first.
If the unit continually trips the breaker, DO NOT continue
resetting the breaker. Instead, have the unit checked by a
qualified service technician.

The input and output jacks are in parallel so the audio input
signal can be daisy-chained to other devices. The “output”
level is the same as the “input” level, and there is no isolation
between the various jacks. The input is medium impedance
balanced. Jack (5a) is a combo female XLR and 1/4" TRS
connector, and jack (5b) is a male XLR.
((66)) VVOOLLUUMMEE
Controls the gain (level) of the Quadra® 15P system. When used
with the Primary Input/Output jacks (5), it directly sets the
system output level. If the microphone input is being utilized in
conjunction with the Primary In/Out jacks, then the mic level is
set using this knob, and the ancillary signal (music into the
In/Out jacks) level is then set using the source or feed (mixer).

Female XLR input jack for using a microphone with the Quadra® 15P system. This connector provides
+15V phantom power and gain suitable for most of today’s “hot” microphones. When using this
input with the regular inputs (5), the volume for the mic should be set first using the Volume (6)
control, and the level fed to the regular inputs should be set to the desired level using the source
level control (mixer).
((99)) CCOONNTTOOUURR SSWWIITTCCHH
When this switch is in the ON position, the mid-range is reduced by approximately 4 dB.

Loop Out receives the signal after the balanced inputs and the Volume control, and sends it to
another Quadra 15P via its Loop In jack. These are unbalanced high-Z jacks, so do not run the cable
very far.
CCAAUUTTIIOONNSS
This unit must be disconnected from the AC power source before any work is done on it. Refer all
servicing to qualified service personnel.
The heat sink on the back plate can become hot to the touch. Do not cover the heat sink or block
from ventilation.
Be sure to keep the microphone away from the front of the speaker after switching the mic input ON
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 Quadra 15P 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.
DO NOT use the Input/Output jacks as mixers or run more than one signal source at a time into
them. The Input/Output jacks (5) are all hard-wired together to allow use of any of the connector
types as an input, and to allow a further send or “daisy-chaining” of the input signal to some other
audio device (such as another Quadra 15P). Attempting to run two different signals directly into the
Quadra 15P could damage the outputs of the source units. Use a mixer to combine two or more
signals into a single signal before sending to the Quadra 15P input.
WWAARRNNIINNGG:: The Quadra 15P is extremely efficient and powerful! This sound system can permanently
damage hearing! Use extreme care setting the overall maximum loudness!
The apparent sound level of the Quadra 15P 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 SPLs in excess of 130 dB at 1 meter from the speaker!

CCaauuttiioonn:: Before attempting to suspend the Quadra 15P, consult a certified structural engineer.
Speakers can fall from improper suspension, resulting in serious injury and property damage. Other
enclosures must not be suspended below one, nor should additional weight be suspended from one
of these units. Use only the correct mating hardware. All associated rigging is the responsibility of
the user.
Always use all four inserts of a given group as a set; NEVER use just one insert to fly a cabinet! The
four insert groupings contain a top group of four and a bottom group of four, and some models also
have a group of four on the rear plane of the cabinet.
Maximum enclosure angle from vertical hang: 30˚
Always loop a suitable safety chain or wire rope through the top handle of the enclosure, and firmly
attach it to a suitable structural member as indicated by a certified structural engineer.
The recommended range of torque for the mounting bolt is 3 to 3-1/2 lb./feet of torque. DO NOT
OVERTIGHTEN! If an insert spins, it has been damaged and the cabinet cannot be flown!
Never transport the cabinet while mounted on an array bracket or other mounting bracket, as this
may unduly stress the mounting inserts.
WWAARRNNIINNGG!!(note to structural engineer)
For the Quadra 15P, the thread insertion depth of the mounting bolt should not be more than 1/2"
past the surface of the cabinet.
If this thread insertion depth is exceeded, the inserts may be damaged or unseated, severely
compromising the mounting integrity of the cabinet!
The correct mounting bolt diameter and threads per inch are: 1/4" X 20. Use of a grade five bolt is
recommended.
GGEETTTTIINNGG AACC PPOOWWEERR TTOO TTHHEE QQuuaaddrraa 1155PP
The Quadra 15P comes with an 8' IEC connection AC power cord. It is likely that some sort of
extension cord will be used with this powered speaker system, so make sure that the extension cord
is no longer than necessary and is of a sufficient current capacity to maintain safety. To maximize the
power output capability of the Quadra 15P’s internal amplifiers and to minimize the voltage drop that
all extension cords cause, do not power anything else from the extension cord used to power the
Quadra 15P. Running just one extension cord back to the wall plug for the entire sound system will
not maximize performance.
The third wire ground plug on the AC plug should NEVER be removed or broken off, as this seriously
compromises safety.

When installing the Quadra® 15P, use AC power runs and a consult certified electrician to make sure
that all AC wiring complies with local codes and regulations. It is also advisable to properly affix a
cable clip to the cabinet to secure the IEC power cord (2) so it cannot vibrate loose.

The built-in pole adapter allows use with the Peavey Q-W™118 subwoofer and the accessory pole it
is designed to use, Peavey part #00326540.
The pole used is 36-3/16" long, and has a nominal diameter of 1-3/8".
GGEETTTTIINNGG AA SSIIGGNNAALL TTOO TTHHEE QQuuaaddrraa 1155PP
There are a variety of ways to input a signal to the Quadra 15P system.
Microphone input usage is covered in a specific section below. The balanced line-level input/s allow
the use of a 1/4" phone plug; either a standard single-ended (tip-sleeve) plug or a balanced TRS
(tip-ring-sleeve) plug; OR either a male or female XLR plug. Do not connect cables to the jacks while
the units are ON and the Volume is turned up!
While a standard, single-ended 1/4" phone plug will work well and the balanced input circuitry will
provide some interference rejection, a balanced cable using either a TRS 1/4" phone plug or an XLR
plug will provide superior interference rejection and performance. With some difficult interference
problems, it may be helpful to lift the shield ground on a balanced cable at the Quadra 15P end only.
Check any input changes carefully, always turning the Volume control down before plugging and
unplugging cables.
Use of high quality premium cables is recommended with the Quadra 15P, as these usually have
better shielding and materials and will provide greater long-term reliability. It is usually a good idea
to leave some slack at the Quadra 15P’s input, and also to tape the cables down or run them under a
cable guard.
VVOOLLUUMMEE CCOONNTTRROOLL AADDJJUUSSTTMMEENNTT
The Quadra 15P is equipped with a Volume control to facilitate use in many different applications.
With the Volume control adjusted fully clockwise, gain is at maximum and the input sensitivity is 0.5
V RMS for full-rated output. When driving the Quadra 15P from a mixer, it may be advantageous to
reduce the input sensitivity by turning the Volume control to the halfway point. The Quadra 15P will
then more closely match a typical power amp input.
If the mixing board indicates clipping on its output signals, then the Quadra 15P’s power capability is
not being utilized cleanly. If this occurs, reduce the mixer output level and turn up the Volume
control on the Quadra 15P.
The amplifiers in the Quadra 15P are equipped with SPS™and an LED indicator to show if it is
engaged or not. 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 Volume control on the Quadra 15P)
needs to be reduced.
When first switching on the sound system, turn on all upstream electronics first, then the Quadra
15P with its Volume 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 Quadra 15P’s
Volume control set to the desired setting (halfway up recommended to start).

With the mic input (8) switched ON (7), a microphone signal will be sent to the Quadra 15P’s preamp
electronics. Be sure to keep the mic away from the front of the speaker after switching the mic input
ON, and while setting the microphone level, or very loud feedback will occur! The person using the
microphone should stand to the side and slightly to the rear of the Quadra 15P, not out in front of the
speaker system. When not using the mic input, be sure to switch off the mic switch (7) for lowest
noise and hum pickup.
Set the microphone level using the Volume control (6), keeping in mind any possible volume
changes during the performance or presentation, and the possibility that the microphone may be
brought closer to the Quadra 15P later on. For best results, the microphone should be held close to
the person’s mouth, instead of a foot or more away. Do not “eat” the mic; that is, do not put your
lips directly onto the mic, as this can often result in a boomy sound. Best results are obtained when
the mic is approximately 2" to 3" away from the mouth.
When using the mic input (8) and the regular inputs (5) for simultaneous music and speech/singing,
the volume for the mic should be set first using the Level control (6) as described above. The level
fed to the regular inputs should be set to the desired level and matched to the microphone levels
using the source level control or a mixer.
UUSSIINNGG OOFF MMUULLTTIIPPLLEE QQuuaaddrraa 1155PPss
(or other Impulse®series powered products)
This unit’s multiple parallel inputs allow daisy-chaining from one to another. Run the first cable from
the mixer to the first Quadra 15P, then connect a cable from one of the first Quadra 15P’s inputs to an
input on the second Quadra 15P. This can be continued for several units, depending on the length
and total capacitance of all the cables. With a low source impedance, such as a typical mixer output,
and typical balanced cables, two or three Quadra 15Ps can be daisy-chained from one output using
30' or 40' cables without obvious loss of high frequencies.
The Loop-Thru jacks (10) can also be used to connect one other Quadra 15P or one other Impulse
series powered unit, while conveniently controlling volume from just one of the units. Connect a
well-shielded 1/4" to 1/4" phone plug patch cord from the Loop Out jack of the unit connected to
the signal source and plug it into the other unit’s Loop In jack. The Volume control of the first unit
now controls the volume for both identically.
Do not connect cables to the jacks while the units are ON and the volume is turned up!
AAPPPPLLIICCAATTIIOONNSS
The Quadra 15P can be used in a variety of applications, such as sound reinforcement, public
address, side fill system or music playback. With the optional monitor stand kit, the Quadra 15P
makes an excellent stage monitor. Presentations or karaoke can be performed by using the mic
input and regular line-level inputs in conjunction.
A typical signal source for the line-level inputs (5) of the Quadra 15P is a sound reinforcement mixing
console (mixer) or the output from a CD player, Minidisc player or tape deck.

First, make sure the unit has AC power and is turned ON. If so, the Power LED (4) should be
illuminated. If it is not, check that the ON/OFF switch (3) is in the ON position, check the IEC power
cord connection (2), making sure it is fully engaged and seated. Make sure the AC line cord is
plugged into a working AC outlet and check the circuit breaker (1) {see the REAR PANEL/Circuit
Breaker section for safety instructions}.
Next, run a cable from the Quadra 15P’s inputs to some other device capable of determining this (for
example, a power amp and speaker) to make sure the inputs of the Quadra 15P are receiving a
signal. If there is still no output, make sure the Volume control has been turned up to a reasonable
level (one-third to halfway).
Has the Quadra 15P been exposed to direct sunlight or excessive heat? If so, it may have triggered
the unit‘s thermal protection. Turn off the unit and cool as best as the situation allows (DO NOT use
liquids for this purpose!).
If there is still no output, it may help to read the owner’s manual completely.
HHuumm oorr BBuuzzzz
As this can be AC outlet-related, try plugging the Quadra 15P into a different AC outlet. Hum
problems may result from using different circuit breakers for the mixer and the Quadra 15P.
Make sure the microphone input (8) is disengaged when not in use by checking the Mic On switch
(7). It should be in the OFF position.
Make sure that shielded cables have been used to transport the signal to the Quadra 15P’s inputs.
Speaker cables with 1/4" or XLR plugs are most likely to hum.
Check to make sure light dimmers are not on the same circuit as the Quadra 15P or the mixer (or any
source devices). If light dimmers are in use, then it may be necessary to turn them full ON or full OFF
to eliminate or reduce hum to tolerable levels. This is an AC wiring/light dimmer interference
problem, and not the fault of the Quadra 15P. The third wire ground plug on the AC plug should
NEVER be removed or broken off, as this seriously compromises safety.
DDiissttoorrtteedd oorr FFuuzzzzyy SSoouunndd
First, make sure the mixer (or signal source) is not clipping or being overdriven. This can sometimes
occur when the Volume control (6) on the Quadra 15P has been set too low (too far
counterclockwise), and it takes a lot of signal to drive the unit to full power.
Make sure the input plugs are fully seated in the input jacks (5) on the rear panel of the Quadra 15P.
Check to see that the proper inputs are being used (5) for line-level signals not the mic input (8).
Make sure that a power amp has not been plugged into the input jacks of the Quadra 15P.
If an extension cord is being used to provide AC power to the unit, make sure it is of sufficient
current capacity and not also being used to supply power to any other units. See “GETTING AC
POWER TO THE Quadra 15P” for details.

The Quadra® 15P has built-in EQ to extend and smooth the natural response of its speakers. Bass
Boost and HF EQ have been applied, and the system has a nominally flat response that should
require little, if any, additional EQ. If excessive additional bass boost or HF boost have been added
externally to the Quadra 15P, it may cause premature overload at high SPLs. Try backing off of any
external EQ (mixer, rack EQ) and see if that clears up any tendency to distort. If the Contour switch
(9) has been engaged, defeat it by making sure it is in the OFF position.
Even though the Quadra 15P is an extremely powerful, high output unit, it does ultimately have
limits and may need additional powered units (or a subwoofer) to provide enough sound output or
coverage.
If the system still exhibits problems after checking everything listed to check, and anything else you
can check safely, carefully note all conditions and check with your Peavey dealer for advice.
Your Quadra 15P is a sturdy and durable product that will provide years of reliable use if properly
maintained. Use common sense and read the safety warnings to avoid hazardous operating
conditions.
To tighten the bolts on the rear panel, remove the front speaker grille and woofer, and then reach in
from the front to stop the nuts from spinning. The unit must be disconnected from the AC power
source before any work is done on it. Refer all servicing to qualified service personnel.
SSuunnlliigghhtt//HHeeaatt
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
return to room temperature before use.
CClleeaanniinngg
Never clean the Quadra 15P while it is plugged in or turned on! When the unit has been fully
disconnected from AC power sources, a dry cloth can be used to remove dirt. Never use strong
solvents on the Quadra 15P, as they could ruin the cabinet. Do not allow ANY fluids to drip inside
the Quadra 15P!

If the QUADRA 15P cabinet becomes scratched or abraded, it can be touched-up using a black
permanent marker. First, if the area to be touched-up is larger than a short scratch, rub it lightly with
an unsoaped plastic scrub pad. Wipe the scratched or abraded area a little at a time with the black
permanent marker and wipe away the surplus with a lint-free cloth. For an overall finish
enhancement and protective coating, use gloves to apply either WD-40®or Armor-All®protectant to
the surface of the plastic cabinet only. Rub the cabinet vigorously with a dry, lint-free cloth if it
becomes slippery form excessive protectant application.
If the grille becomes discolored, you can use a cleaner such as 409®or Fantastic®to remove it. Rub a
clean, slightly dampened cloth across the front surface of the grille.

After the first few months of use and periodically thereafter, check the hardware of the Quadra®15P
for tightness, including 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 them to loosen with
use.
The Peavey Architectural Acoustics®Quadra 15P is a powered, bi-amplified two-way speaker system
engineered to provide the highest levels of performance possible in a compact, powered
loudspeaker. Capable of over 130 dB peak SPLs, this system can pump out a huge amount of sound.
The enclosure utilizes high-impact polypropylene in an injection-molded plastic trapezoidal form,
with a coated, perforated metal grille to offer an aesthetically pleasing-yet-durable powered speaker
system.
This two-way powered system is comprised of an 800 Watt dynamic peak power amplifier driving a
15" BWX Black Widow®woofer (1508-4 SPS) with a Kevlar™impregnated cone, surround and dust
cap specially treated for excellent weather resistance. The RX™22 compression driver is driven by a
200 Watt peak dynamic power amplifier and features a 2" titanium diaphragm, covered by U.S.
Patent #6064745 (UK GB 2 329 789) for the Radialinear Planar Phase Correction System used in its
phase plug. It is coupled to a patented Quadratic Throat Geometry constant directivity horn (U.S.
Patent #6059069) with a coverage pattern of 90˚ x 45˚, molded integrally into the enclosure.
Balanced inputs provided to the preamp/EQ electronics are one combo female XLR and 1/4" TRS
phone jack, and one male XLR, all connected in parallel. A separate, switchable microphone input
(female XLR) is also provided. The power amplifiers providing the bi-amplification are low distortion
units pushing 400 Watts RMS into the nominal 4 Ohm load of the woofer and 100 Watts RMS into
the nominal 6 Ohm load of the tweeter. They were selected for their reliability and superb musical
performance capability. Both amplifiers feature our patented SPS™compression, which virtually
eliminates audible power amplifier clipping.
Multiple molded-in handles make transport easy, while multiple mounting points (top, bottom and
rear) for the Peavey Versamount™70 and a molded-in stand adapter provide maximum utility.
The Quadra 15P powered loudspeaker system shall have a frequency response from 56 Hz to 18 kHz.
The peak SPLs with inaudible distortion shall reach 130 dB with music as a source, when measured
at a distance of 1 meter and driven to full output capacity. The system shall utilize a 15" BWX Black
Widow®woofer and an RX™22 compression driver tweeter. The nominal radiation pattern shall be 90˚
in the horizontal plane and 45˚ in the vertical plane.
This powered, bi-amplified loudspeaker system shall have a group of medium impedance input
connectors consisting of one combo female XLR and 1/4" TRS phone jack and one male XLR, all on
the rear panel and connected in parallel. Additionally, a separate, switchable microphone input
(female XLR) shall be provided. A Loop Out and a Loop In jack shall be provided. A Volume control
will be located next to the input jack group.
The system’s power amplifiers shall have an unfiltered frequency response of 10 Hz to 30 kHz, which
deviates no more than +0, -1 dB up to rated power; a damping factor greater than 100 @ 1 kHz into
4 Ohms; hum and noise better than 90 dB below rated power; and THD and IMD less than 0.1%.
The woofer amplifier shall be capable of 400 Watts into a 4 Ohm nominal load and the tweeter
amplifier shall be capable of 100 Watts output into a 6 Ohm load, and both shall incorporate
independent SPS™compression.
The input signal shall be electronically divided into high frequencies and low frequencies by a
staggered pole, third order slope, line-level crossover at 1.8 kHz. The low frequencies shall be
processed to provide bass boost, subsonic filtering and overall response shaping, and the high
frequencies shall be equalized for constant directivity horn EQ and response shaping.

The enclosure shall be constructed of 1/4" injection-molded polypropylene with a UL flame rating
and internal reinforcing ribs. A handgrip shall be molded into each side of the woofer and on the top
rear edge.
A vinyl-coated, perforated metal grille shall be provided for woofer protection. The cabinet shall
incorporate four tall, sturdy rubber feet for floor-standing use and four mounting point inserts on the
top and bottom each for flying use.
The outside dimensions shall be 28.5" high by 21.25" wide (11.5" wide in rear) by 17" deep, and the
weight shall be 69 lbs. Power requirements shall be: 660 Watts, 120 V AC, 60 Hz Domestic and
240 VAC, 50 Hz (European). The loudspeaker system shall be called a Peavey Architectural
