QM350i User Manual WARNING When Installing the Unit • Do not expose the unit to rain or an environment where it may be exposed to water or other liquids, as doing so may result in damage to the bass driver or corrosion of the steel protective grill. • Do not cut, kink, otherwise damage nor modify the speaker cable. Also use speaker cable of at least 1.5mm core diameter. In addition, avoid locating the speaker cables close to heaters, high traffic areas or locations where the cables can be damaged.
QM350i User Manual General Description These are intended to be used with the WB350i wall bracket. The QM350i is a passive two way bass reflex design speaker suitable for mobile or installation use. The design characteristics of the QM350i make it suitable for both full range use or as the high-mid component of a multi way system with sub-bass enhancement.
QM350i User Manual Getting The Best From Your QS350i Connections Suitable Amplification The QM350i is an 8 ohm enclosure and can be connected in multiple parallel connections to an amplifier channel that can operate at speaker impedances of 4 ohms. The QM350i is a mid power level high efficiency system, so ultra high power is not necessary to obtain high sound pressure levels. The recommended power range per amplifier channel is 350 - 500 watts RMS into an 8Ω load or up to 1,000W RMS into a 4 ohm load.
QM350i User Manual Speaker cables Speaker cable needs to be as heavy gauge as conveniently possible for low-loss results. Light gauge cable (below 1.5mm) will create extra resistance and waste amplifier power. This particularly applies to long speaker runs. The amplifier’s damping factor statistic (“punch” for the non technical) is greatly diminished, so keep your speaker cables short and as heavy gauge as practical.
QM350i User Manual Flying the QM350i 6 Before suspending any speaker system always inspect all components (enclosure, rigging frames, track fittings, etc.) for cracks, deformations, corrosion, missing, loose or damaged parts that could reduce strength and safety of the array. Do not suspend the speaker system until the correct preparation of the installation site has been taken to avoid health risks during and after the completion of the installation.
