[. . . ] If this product is to be mounted in an equipment rack, rear support should be provided. 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. Government's Occupational Safety and Health Administration (OSHA) has specified the following permissible noise level exposures: Duration Per Day In Hours 8 6 4 3 2 1 1/2 1 1 /2 1 /4 or less Sound Level dBA, Slow Response 90 92 95 97 100 102 105 110 115 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. SAVE THESE INSTRUCTIONS! 3 ENGLISH QTM SERIES EQUALIZERS Thank you for purchasing a Peavey Electronics Q Series graphic equalizer. The Q family features one dual-channel model (Q2151) and one single-channel model (Q1311), both incorporating Peavey's legendary low noise, low distortion design. These ruggedly constructed Q Series EQs have 20 mm, center-detented control sliders enclosed in metal for durability. These one rack-space units also offer ±12 dB gain control, switchable ±12 dB or ±6 dB frequency band boost/cut and an LED display indicating output level. Other shared features include switchable low cut filters, bypass switches and +21 dBu balanced inputs and outputs. Q Series EQ 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 Q Series has an EQ for you. FEATURES Q2151 · Dual channel (15 bands per channel) · 2/3 octave filter sets · 25 Hz to 16 kHz effective equalization range · Constant Q filters · Switchable ±12 dB/±6 dB of boost/cut in each frequency band · Output level LEDs (-12 to +12 dB) · 24 dB per octave 40 Hz low cut filter with status LED · XLR and 1/4" TRS inputs and outputs for balanced or unbalanced operation · Bypass switch with status LED · ±12 dB gain control Q1311 · Single channel (31-band) · 1/3 octave filter sets · 20 Hz to 20 kHz effective equalization range · Constant Q filters · Switchable ±12 dB/±6 dB of boost/cut in each frequency band · Output level LEDs (-12 to +12 dB) · 24 dB per octave 40 Hz low cut filter with status LED · XLR and 1/4" TRS inputs/outputs for balanced or unbalanced operation · Bypass switch with status LED · ±12 dB gain control 4 EQUALIZATION PROCESS Always begin the equalization process with all sliders at their center-detent (flat response) positions. Lower each fader until the feedback frequency is found. Lower the faders in small amounts to avoid adversely affecting sound quality. Likewise, excessive boosting of a frequency may result in feedback. EXERCISE CAUTION WHEN ATTEMPTING TO BOOST FREQUENCIES BELOW SPEAKER SYSTEM TRANSDUCER CUT-OFF. Typical sound reinforcement enclosures are not designed for 20 Hz performance, and transducer damage could result from "over-boosting" low frequencies. Excessive boost at very low frequencies could also limit overall system headroom. Engaging the 40 Hz low cut filter is the best way to avoid these problems. NOTE: Superb tonality, absence of feedback and great-sounding systems may not be attainable regardless of the equalizer used; all system components must be of high quality and designed for the application. No amount of equalization will correct poor acoustics, poor microphone/speaker arrangement or the response curve of a poor loudspeaker.
