Important Safety Instructions

WARNING: When using electric 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. 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 manufacturer’s 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.

Q 231F Dual specifications

The Peavey Q 231F Dual is a sophisticated dual 31-band graphic equalizer designed to provide unmatched audio performance and versatility, catering to live sound engineers, musicians, and audio enthusiasts alike. This high-quality equalizer delivers precise control over audio frequencies, allowing users to shape their sound environments with unparalleled accuracy.

One of the standout features of the Q 231F Dual is its dual-channel design, which enables simultaneous control of two audio paths. Each channel offers a full 31 bands of equalization, covering a frequency range from 20 Hz to 20 kHz. This extensive bandwidth allows users to target specific frequencies that may cause feedback or muddiness in a mix, ensuring that the overall sound remains clear and balanced.

The Q 231F is equipped with a unique Constant-Q filter design. This technology not only preserves the bandwidth of adjacent frequency bands when making adjustments but also ensures that boosts and cuts have a more natural sound. As a result, engineers can make precise corrections without introducing unwanted resonances or artifacts, leading to a more professional audio output.

Another significant characteristic of the Q 231F Dual is its built-in 12 dB/octave high-pass filter on both input channels. This feature helps eliminate low-frequency rumble, allowing for cleaner mixes and clearer vocal performances, which is particularly beneficial in live sound settings. Additionally, the equalizer includes a switchable bypass setting, allowing users to easily compare their processed sound against the original audio signal.

The Q 231F also boasts a reliable LCD display, providing visual feedback for the adjustment of gain settings and equalization levels. The illuminated sliders offer excellent visibility, even in low-light conditions, a crucial feature for performers and sound engineers working in dynamic environments.

Furthermore, Peavey has designed the Q 231F with rugged construction and intuitive layout, ensuring it withstands the rigors of live performance while remaining user-friendly. The unit is housed in a sturdy 1U rack-mountable chassis, making it easy to integrate into any existing audio setup.

In conclusion, the Peavey Q 231F Dual excels in providing extensive equalization control, advanced filtering technologies, and user-friendly features, establishing itself as a top choice for audio professionals aiming to achieve exceptional sound quality in any live or studio application. Its robust design and high-performance capabilities make it an essential tool for those seeking to elevate their audio experience.
