User manual YAMAHA VXC4/VXC4W ANNEXE 1

[. . . ] Prolonged use in this condition could cause overheating and result in fire. • When choosing a power amplifier for use with this device, make sure that the output power of the amplifier is lower than the power capacity of this device (see SPECIFICATIONS). Even if the output power of the amplifier is lower than the power capacity of this device (program), use of excessive input signals resulting in clipping may cause damage to the device. Malfunction or fire may occur especially when the following sounds or noises are generated: - feedback, when using a microphone - continuous and extreme volume sound from a musical instrument - extreme continuous distorted sound - noise caused by plugging/unplugging the cable while the amplifier is turned on NOTICE To avoid the possibility of malfunction/damage to the product, damage to data, or damage to other property, follow the notices below. Grille Shape Back Can Material Baffle Material Material CAUTION Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the device or other property. [. . . ] • Construction work should be carried out in accordance with constructionrelated law and always by a professional constructor. If the device installation requires construction work, make sure to observe the following precautions. - Choose mounting hardware and an installation location that can support the weight of the device. - Avoid locations that are exposed to constant vibration. - Use the required tools to install the device. - Inspect the device periodically. *1: IEC shaped pink noise with 6 dB crest factor. *2: Half-space (2π) *3: Calculated based on power rating and sensitivity, exclusive of power compression. DIMENSIONS Unit: mm VXC4/VXC4W O-ring 243 164 85 Ø243 Ø183 Connections • Before connecting the device to a power amplifier, turn off the power for all devices. Before turning the power on or off for all devices, set all volume levels to minimum. • Use only speaker cables for connecting speakers to the speaker jacks. Use of other types of cables may result in fire. Maintenance • Do not wipe the outer packaging with benzine, thinner, or synthetic detergent and do not use electrical contact cleaner. These may damage the outer packaging and dissolve the parts. ● About This Manual The illustrations as shown in this manual are for instructional purposes only, and may appear somewhat different from those on your device. Yamaha cannot be held responsible for damage caused by improper use or modifications to the device. Tile Rail 608 38 644 32 28 INSTALLING THE SPEAKERS Install the speakers onto the ceiling with the supplied hardware. Ensure that the strength of the ceiling rail is sufficiently strong. Pre-installation (Preparation of the Cable) Use stranded wire for cables attached to the Euroblock connector. Strip their insulation as shown in the figure and connect them. About 7 mm (0. 3 in. ) There are two acceptable wiring methods. CAUTION When connecting with low impedance, take note of the combined resistance. Using Loop-Through Terminals For this method, cables are connected from terminals 1 and 4 to the subsequent speaker. If the Euroblock connector is disconnected from a speaker, all subsequent speakers will not work. This can be useful to identify which speaker has a problem. 7 Hold the cable in the strain relief clamp, then tighten screws A and B. When all the Anti-Drop tabs cross over the O-ring, the speaker is held temporarily. You can release your hands from the speaker. NOTE Do not plate stranded wires by solder. Doing so will cause the wire to break. 8 Close the terminal cover and tighten the screw. From amplifier or previous speakers To subsequent speakers To subsequent speakers To release the speaker from the O-ring, press the Anti-Drop tabs. These are located above the U mark near the edge of the cabinet’s face. 1 CUT OUT A HOLE IN THE CEILING 1 Put the supplied cutout template to the ceiling and draw a circle by tracing it. [. . . ] Otherwise, the speaker may fall or malfunction. 3 CONNECT THE WIRING TO THE CONNECTOR AND FIX THE CABLE 1 Pull the wiring from the amplifier through the cut hole. 2 Loosen the screw at the right of the terminal cover to open the terminal cover and remove the Euroblock connector. Speaker 5 SET THE LINE VOLTAGE/IMPEDANCE AND POWER Select the line voltage/impedance (100V/70V/8Ω) and power tap for 100V/ 70V line distributed system, by rotating the tap selector switch on the front side of the speaker with a flat-blade screwdriver. 4 Plug the connected Euroblock connector into the socket in the speaker. Euroblock connector CAUTION The “X” position should not be selected. The 8Ω position should be selected for 8Ω audio systems only. If the setting is incorrect, it may cause malfunction of the speaker and amplifier. Terminal cover 5 Loosen the screw A of the strain relief clamp. [. . . ]
