ENGLISH SAFETY AND OPERATING PRECAUTIONS Before connecting and using this product, please read this user manual carefully and keep it on hand for future reference. This manual is to be considered an integral part of this product and must accompany it when it changes ownership as a reference for correct installation and use as well as for the safety precautions. RCF S.p.A. will not assume any responsibility for the incorrect installation and / or use of this product.
ENGLISH 11. Hearing loss Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that leads to hearing loss is different from person to person and depends on the duration of exposure. To prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection devices. When a transducer capable of producing high sound levels is being used, it is necessary to wear ear plugs or protective earphones.
ENGLISH RCF S.p.A. thanks you for purchasing this product, which has been designed to guarantee reliability and high performance. DESCRIPTION MR series monitors are two-way compact speakers. Enclosures are made of self-extinguishing high-density plastic, with a frontal protective grille and four M6 threaded inserts for either the included or the optional mounting hardware.
NOTES ABOUT THE LOW IMPEDANCE CONNECTION (8 Ω) MR 40T, MR 40T W ENGLISH - IMPORTANT: on models MR 40T, MR 40T W, MR 50T, MR 50T W (equipped with an internal transformer), it is necessary to set the rear power selector to 8 Ω. MR 50T, MR 50T W - The total speaker impedance must not be lower than the amplifier output impedance. - A speaker total impedance equal to the amplifier output one permits to get the maximum deliverable power (but a higher impedance entails less power).
ENGLISH POWER SELECTION WHEN LINKED TO 70 / 100 V CONSTANT VOLTAGE LINE (MR 40T, MR 40T W only) If this speaker is connected to a 100 / 70 V constant voltage line, select its proper power rate by turning its rotary switch (by using a screw-driver) among the values 20 – 10 – 5 – 2.5 W (100 V) or 20 – 10 – 5 – 2.5 – 1.25 W (70 V).
ENGLISH The two INPUT contacts (+ and -) allow the connection of the input cable, the two LINK contacts (+ and -) can be linked to an output cable for the parallel connection of other speakers. Applicable wire section: from 0.75 mm² to 4 mm². 1. Connect the line positive wire to the speaker INPUT +. 2. Connect the line negative wire to the speaker INPUT –. 3. If necessary, connect in the same way the output cable (to link other speakers in parallel) to speaker LINK + and LINK –.
ENGLISH INSTALLATION WARNING: MAKE SURE ALL SPEAKERS ARE INSTALLED IN A STABLE AND SECURE WAY IN ORDER TO AVOID ANY CONDITIONS THAT MAY BE DANGEROUS FOR PERSONS OR STRUCTURES. ENSURE THE SUPPORT SURFACE (WALLS, CEILINGS, ETC.) HAS THE NECESSARY MECHANICAL CHARACTERISTICS TO SUPPORT THE SPEAKER WEIGHT.
