product, keep in mind the technical specifications indicated in the dedicated section of this instruc- tion manual.

9. Accessories – Install and use this productonly with

the accessories specified by the manufacturer or supplied with the product. Hearing loss - Exposure to high sound levels can cause permanent hearing loss. The sound pressure level which leads to hearing loss varies considerably from one person to another, and depends on the duration of exposure. The U.S. Government’s Occupational Safety and Healt Administration (OSHA) has established the maximum sound pressure levels that can be with stood without causing damage, which are shown in the table below. According to the OSHA regulations, any exposure over the maximum limits indicated in the table can reduce the hearing capacity of a person. To prevent poten- tially dangerous exposure to high sound pressure levels, anyone subjected to such levels must use sui- table protection. When an product capable of produ- cing high sound levels is being used, it is therefore necessary to wear ear plugs or protective earphones when the limits shown in the table are exceeded.

ENGLISHConsult the specifications provided in the instruc- tion manual to know the maximum sound pressure (SPL) the speaker is capable of producing. Unpacking the speaker Remove the speaker carefully from its packaging to avoid damaging it. Should the speaker appear to be damaged, put it back in the original packaging and take it immediately to your dealer or to the nearest RCF S.p.A. Description The MONITOR 55 (Black) and MONITOR 55W (White) are a compact two-way speaker system designed for constant-impedance system. The 5” (130 mm) carbon fiber woofer, in combination with a 0.75” (19 mm) soft dome tweeter mounted on a 110° x 110° constant directivity horn, provide natural, smooth sound repro- duction, ideal for use in business music systems and indoor/outdoor background music applications. The passive crossover is designed to reduce heat dissipation and optimise the power response of the loudspeaker. The connections are made using gold plated banana terminals or bipolar cables having a suitable cross-section. The enclosure is constructed of high-density plastic, with M6 threaded inserts for use with the optional mounting hardware, and includesa protective perfora- ted steel grille. Installation The special hexagonal shape of the cabinet makes it possible to position the speaker in various way, as shown in the figure. The RCF plate on the front protec- tive grille can be rotated to adapt it to the position of the speaker. The speaker bodyhasfour M6 threaded inserts, one each on the top and bottom and two on the back, used for attaching accessories for installing the speaker in different ways.

The MONITOR 55 and MONITOR 55W speakers are supplied with a black (white) ball joint support for wall mounting. WARNING - Consult a professional rigger or structural engineer prior to suspending loudspeakers from a structure not inten- ded for that use. Always know the working load limitof the structure supporting the loudspeaker array. Always make sure that the rigging hardware minimum rating is at least five times the actual load.

M6Connections The gold-plated banana jacks are designed to accept single or double banana plugs and two-pole cables. They provide a method of quickly connecting and disconnecting speaker cables to and from the speaker. Double banana plugs have a tab on own side to indicate the ground (GND) side of the connector.

In general, remember that the speaker positioned to the right of the ideal listening point must be con- nected to the RIGHT channel of the amplifier and the speaker on the left to the LEFT channel. Phasing For the best musical reproduction, it is essential that the speakers be connected in phase. For this purpose, the terminals of the MONITOR are marked with red (+) or black (-) rings. Make sure that you connect the terminal with red ring to the corresponding speaker terminal on the amplifier (+, POS), and follow the same procedure for the terminal with black ring. MONITOR 55 / 55W

The side connects to the negative (-) terminal. If you use bipolar cables, we recommend choosing cables that have a suitable cross-section (maximum diameter 6mm), as poor quality cables or those of unsuitable size may cause power loss and sound degradation.Specifications Enclosure: 2 – way reflex system Long-Term power handling*: 175 W (IEC268-1) Frequency response: 65 – 23.000 Hz ±2 dB 55 – 25.000 Hz –10 dB Sensitivity (1W / 1m): 87dB SPL in anechoic chamber Max SPL:

109.5 dB 1 m in anechoic chamber.

(175 W IEC Long-Term) Impedance: 4 ohm Crossover frequency: 3000 Hz Crossover: 12/18 dB/oct low impedance compensated crossover. Components: Low frequency : 5" (130 mm) carbon fiber woofer. High frequency : 0,75" (19 mm) driver loaded by 110° x 110° constant directivity horn. Tuning frequency: 65 Hz

• Long term maximum input power isdetermined by submitting the speakersto a power test lasting 1 hour, in which a special signal (IEC268-1) is applied 20 times for 1 minu- te each, with an interval of 2 minutes between one application and the next. The spe- cial signal is generated by filtering pink noise with a weighting device that makes a cut with 12 dB/octave slope below 55 Hz and above 5 kHz, and maintains the 6 dB peak/average ratio. The maximum power the speaker is able to withstand without any permanent damage is taken as the value of long-term maximum input power.
