[. . . ] Este símbolo tiene el propósito de alertar al usario de la presencia de instruccones importantes sobre la operación y mantenimiento en la información que viene con el producto. PRECAUCION: Para disminuír el riesgo de descarga eléctrica, no abra la cubierta. Deje todo mantenimiento en manos del personal técnico cualificado. ADVERTENCIA: Para evitar descargas eléctricas o peligro de incendio, no deje expuesto a la lluvia o humedad este aparato Antes de usar este aparato, Iea más advertencias en la guía de operación. Ce symbole est utilisé dans ce manuel pour indiquer à l'utilisateur la présence d'une tension dangereuse pouvant être d'amplitude suffisante pour constituer un risque de choc électrique. [. . . ] Cables can be connected with banana plugs, spade lugs, or bare wire to the 5-way binding posts. Pin connections are noted on the rear panel of the unit. Connecting Power The CS 1200 power requirements are rated at 1/8 power (typical music conditions). The maximum power current draw rating is limited only by the front panel circuit breaker. Consult the specifications in this manual for figures on the current that this amplifier will demand. Make sure the mains voltage is correct and is the same as that printed on the rear of the amplifier. Damage caused by connecting the amplifier to improper AC voltage is not covered by any warranty. Unless otherwise specified when ordered, Peavey amplifiers shipped to customers are configured as follows: North America: 120 VAC/60 Hz Europe, Asia, Australia: 230/240 VAC/50 Hz South America: 120 VAC/60 Hz or 240 VAC/50 Hz Operation Modes Stereo For stereo (dual channel) operation, turn the amplifier off and set the mode select switch to the stereo position. In this mode, both channels operate independently of each other, with their input attenuators controlling their respective levels. See the specifications at the end of this manual for standard voltage gain and input sensitivity information. When operating in the bridged mode, the channel A attenuator controls the signal. See the section on Bridged Mono Operation for more information and precautions. Front Panel Indicators The CS 1200 features four front panel discrete LED indicators per channel: ACTIVE , DDT , TEMP and DC . This output remains at low frequencies independent of the Amp Function switch setting. Speakon® Output Connector (19) Each channel features a four-wire Speakon connector for the output. In both channels, the 1+ pin is the channel signal output and the 1- pin is chassis ground. On the Channel A connector, the 2+ pin carries the Channel B signal output and the 2- pin is chassis ground. Binding Post Output Connectors (20) Each channel features a pair of shock-proof binding posts connected in parallel with the Speakon connector. The red binding posts are the signal output from each channel, and the black binding posts are chassis ground. The Channel A red binding post should be considered the positive output for the system and should be connected to the positive input of the associated loudspeaker system. AC Line Cord Connector (21) Provided to accept the removable (IEC) type AC line cord. Connect only to proper source (see back panel markings). 9 Protection Features The CS 1200 incorporates several circuits to protect both itself and loudspeakers under virtually any situation. Peavey has attempted to make the amplifier as foolproof as possible by making it immune to short and open circuits, mismatched loads, DC voltage, and overheating. If a channel goes into the Distortion Detection or DDT gain reduction mode, the speaker load remains connected, but clipping percentage or output power are instantly reduced. When a problem occurs that causes a channel to go into a protection mode, the TEMP LED or DC LED for that channel will glow. DC voltage on the output, excessive subsonic frequencies, or thermal overload will cause the channel's output relay to disconnect the speaker load until the problem is corrected or the amplifier cools down. DDT Peavey's DDT compression system allows maximum performance of the amplifier/speaker combination by preventing the power amp from running out of headrooom (clipping). This compression system is activated by a unique circuit that senses signal conditions that might overload the amplifier and reduce the amplifier's gain when clipping is imminent.
