User manual YAMAHA VXC4-VA VXC4-VAW

[. . . ] Connecting an impedance load outside the amplifier’s rated range can damage the amplifier. • When connecting the speakers with high impedance, be sure that the total rated input capacity of the speakers does not exceed the output power of the amplifier. • When using a high-impedance speaker connection, make sure the audio signal is passed through an 80 Hz or above high-pass filter before being input to the speakers. • Do not swing the speaker by its carrying band. [. . . ] - Inspect the device periodically. ● Protective circuit This speaker system has an internal protection circuit that shuts off the speaker unit when an excessive input signal is applied. If the speaker unit emits no sound, reduce the volume level of the amplifier immediately. The sound will return automatically in several seconds. ● About this manual • The illustrations as shown in this manual are for explanation only, and may appear somewhat different from your device. • The company names and product names in this manual are the trademarks or registered trademarks of their respective companies. Connections • Before connecting the device to other devices, turn off the power for all the other 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. The specifications data was measured in an anechoic chamber, according to EN 54-24. Reference axis: Axis is on the center of grille surface and perpendicular to the grille surface. Reference plane: Plane is on the grille surface and perpendicular to the reference axis. Horizontal plane: Plane is containing the reference axis and perpendicular to the reference plane. *1: Half-space (2π) *2: IEC shaped pink noise with 6 dB crest factor. *3: Calculated based on power rating and sensitivity, exclusive of power compression. The contents of this manual apply to the latest specifications as of the printing date. Since Yamaha makes continuous improvements to the product, this manual may not apply to the specifications of your particular product. To obtain the latest manual, access the Yamaha website then download the manual file. Since specifications, equipment or separately sold accessories may not be the same in every locale, please check with your Yamaha dealer. The dimensions are shown in “Technical Specifications”. Handling caution • Do not insert your fingers or hands in any gaps or openings on the device (ports). • Do not rest your weight on the device or place heavy objects on it. • Do not operate the device if the sound is distorting. Prolonged use in this condition could cause overheating and result in fire. • Do not pull the cables connected. • 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”). [. . . ] 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 ceramic terminal. Strip their insulation as shown in the figure and connect them. About 7 mm (0. 3") Note Prepare a cable gland of AVC part no. CAUTION Use an appropriate tool for opening the hole. [. . . ]
