Congratulations on purchasing the Q
215FX! Peavey engineers have taken graphic equalizers to the next
level with its introduction. We trust that you are eager to place this unit into YOUR system ASAP.
The Q215FX offers two channels with 15 bands of 2/3 octave filters featuring superior constant “Q” devices.
Each channel has Peavey's exclusive FLS
Feedback Locating System that consists of LED indicators
above the frequency bands to identify the presence of a high energy signal (usually feedback). This sophisti-
cated feedback detector system will allow you to quickly identify and remove feedback. It works like this:
when the feedback detection circuit detects the frequency band with the most energy, it causes the LED
above the associated frequency band to illuminate. By moving the fader downward for that band, the likeli-
hood of feedback is reduced/eliminated.
Most use the Q
215FX in one of two ways:
1. To catch and reduce/eliminate feedback “on-the-fly” during a performance.
2. To determine frequency bands that are susceptible to feedback BEFORE the performance, eliminating
them in advance. How do you do this? After the system is set up, slowly bring up the microphone levels.
As they start to feedback, note the LED activity on the Q
215FX feedback bands. Move the faders to
decrease the “identified” bands. Now you have eliminated a high percentage of potential feedback
problems before the performance even begins!
NOTE: It is common for feedback to be active over several frequency bands. Also, go easy when making
fader adjustments since extreme movements will affect your performance and be counter productive. If any
operational questions come up, be sure and contact our Customer Service department at (601) 483-5365.
Thanks for supporting Peavey!
OPERATION NOTE
For best results, set the mixer levels high enough to cause the Feedback Locating System LEDs to become
active (0 dBV, 1 V RMS). This may require you to turn down the power amp to maintain an acceptable
volume level.
This equalizer is designed to provide room equalization, feedback control and system tone control. No
amount of equalization will correct an acoustically bad room/mic/speaker arrangement or completely correct
the response of a poor loudspeaker.
Always begin with all sliders in the “O” position and avoid excessively cutting large segments of the audio
passband, which would limit the system’s dynamic range.
Exercise caution when attempting to boost equalization below cutoff of the speaker system. Typical sound
reinforcement enclosures are not designed for 20 Hz performance and transducer damage could result.

FRONT PANEL FEATURES
EQUALIZER SECTION (1)
There are two 15-band 2/3-octave filter sets. The filters are constant “Q” devices located at ISO center
frequencies. Effective equalization range is from 25 Hz to 16 kHz per channel. Maximum cut per frequency
is 18 dB and the boost per frequency is 12 dB.
AUTOMATIC FEEDBACK LOCATING LEDS (2)
When feedback occurs, the LED of the frequency band that is feeding back will illuminate, indicating the
slider to be adjusted. The LED will remain illuminated for a few seconds even after the feedback is gone.
This is to allow you to see where the feedback is if the feedback goes away before any correction is made. If
there is no feedback occurring, the LED of the frequency band with the most signal in it will illuminate. Just
because the LED is illuminated does not mean that there is feedback occurring.
OPERATING THE FEEDBACK LOCATING SYSTEM
The feedback locating system is normally used in one of two ways.
1. To catch and reduce/eliminate feedback “on-the-fly” during a performance.
2. To determine frequency bands that are susceptible to feedback before the performance, and elimi-
nate them in advance. This is done after the system is set up, by bringing up the microphone levels
slowly to the point of feedback. As they start to feedback, note the LED activity on the Q
215FX.
Move the faders to decrease the “identified” bands. Now you have eliminated a high percentage of
potential feedback problems before the performance even begins.
Note: It is not uncommon for feedback to occur over several frequency bands. Also, go easy when making
fader adjustments since extreme movements will affect your performance and be counter productive. Some
feedback or ringing, although audible, may not be louder than the other program material and may not light
an LED.
GAIN (3)
Calibrated control for regulating overall gain of the equalizer section. Unity gain throughout the signal chain
may be maintained by recovering lost signal at this point.
For example: Assume the equalization process has introduced a signal loss of -6 dB by negative (-) adjust-
ment of the EQ section. The gain should then be adjusted to +6 to maintain unity gain through the equalizer.
LOW CUT (4)
Provides high pass filtering at 40 Hz in the “in” position. Low frequency roll-off is at 12 dB per octave.
LOW CUT LED (5)
With the Low Cut switch in the “in” position, this LED will illuminate indicating a low frequency roll-off at
12 dB per octave at 40 Hz
BYPASS LED (6)
This LED will illuminate when the Bypass switch is in the “in” position, indicating that the EQ and gain
controls are bypassed.
BYPASS (7)
In bypass mode (switch in), the input signal is routed directly to the output and is unaffected by all front panel
controls except the low cut filter.
LED LEVEL METER (8)
This multicolored LED ladder indicates output level.
POWER SWITCH (9)
Used to turn AC mains power on or off.

1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water. For example, near or in a bathtub, swimming pool, sink, wet basement,
etc.
6. Clean only with a damp cloth.
7. Do not block any of the ventilation openings. Install in accordance with manufacturers instructions. It should
not be placed flat against a wall or placed in a built-in enclosure that will impede the flow of cooling air.
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. When the provided plug does not fit into your inlet, consult an
electrician for replacement of the obsolete outlet. Never break off the grounding 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.
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. Only use attachments/accessories provided by the manufacturer.
12. 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.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. 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.
15. If this product is to be mounted in an equipment rack, rear support should be provided.
16. 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
8 90
6 92
4 95
3 97
2 100
1 1/2 102
1 105
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.
