IMPORTANT SAFETY INSTRUCTIONS
WARNING: 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. 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. 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.
16. If this product is to be mounted in an equipment rack, rear support should be provided.
17. 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.
18. This electrical apparatus should not be exposed to dripping or splashing and care should be taken not to place objects
containing liquids, such as vases, upon the apparatus.
19. The on/off switch in this unit does not break both sides of the primary mains. Hazardous energy can be present inside the
chassis when the on/off switch is in the off position. The mains plug or appliance coupler is used as the disconnect device, the
disconnect device shall remain readily operable.
20. 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
8 90
6 92
4 95
3 97
2 100
11⁄2 102
1 105
1⁄2 110
1⁄4orless 115
According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Earplugs 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.

Graphic Equalizers
Thank you for purchasing a Peavey Electronics QF Series graphic equalizer. The QF family features one dual-channel
model and one single-channel unit, all incorporating Peavey’s legendary low-noise, low-distortion design. Ruggedly
constructed, QF Series EQs have 45 mm, center-detented control sliders enclosed in metal for durability. These two
rack-space units also offer ±15 dB gain control and an LED display indicating output level. Other shared features include
switchable low-cut filters, +21 dBu balanced inputs and outputs, and bypass switches. QF Series equalizer filters are
set at ISO center frequencies within 3% accuracy. Whether on stage, in the studio, or simply tweaking your home hi-fi
system, the QF Series has an EQ for you.
Please read this guide carefully to ensure your personal safety as well as the safety of your equipment.

This LED array indicates output level from –12 dB to +12 dB.
This calibrated, detented control regulates overall gain of the EQUALIZER SECTION (3). Unity gain throughout the
signal chain can be maintained by recovering lost signal gain at this point. The equalization process may result in
noticeable signal loss. To compensate for this loss, engage the BYPASS (5) switch and compare the signal level with
that of the equalized level. Increase the GAIN control until the equalized level approximates that of the bypassed
level. Let your ears be your guide.
These calibrated, detented controls adjust the amount of cut or boost at their respective frequencies. They are
adjustable from 18 dB cut to 12 dB boost. For units equipped with FLS®, the LED at the top of each band will
illuminate as an indication of feedback at that frequency.
This switch activates the low-cut filter that rejects frequencies below 40 Hz. Frequency roll off is 24 dB per octave
with the switch engaged. This filter will operate even with the BYPASS (5) switch engaged. The adjacent red LED
indicates activation.
This switch allows the signal to bypass the unit with the exception of the LOW-CUT FILTER (4). When this switch is
engaged, the signal is routed from INPUT (10 and 11) through the low-cut filter to output (8 and 9).
The green LED indicates activation.

This is a standard IEC power connector. An AC mains cord having the appropriate AC plug and ratings for
the intended operating voltage is included in the carton.
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 equalizer and all associated equipment is properly grounded.
If the colors of the wires in the mains lead of this unit do not correspond with the colored markings
identifying the terminals in your plug, proceed as follows: (1) 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. (2) The wire that is colored blue must be connected to the terminal that is
marked with the letter N or the color black. (3) The wire that is colored brown must be connected to the
terminal that is marked with the letter L or the color red.
These 1/4" tip/ring/sleeve (stereo) jacks provide balanced output when used with TRS connectors and
2-conductor shielded cables. When used with a mono 1/4" (TS) phone plug, the output is unbalanced.
These male 3-pin connectors provide balanced output when used with female XLR connectors.
These female 3-pin connectors provide balanced input when used with male XLR connectors.
