User manual ELECTRO-VOICE 667 DATASHEET

[. . . ] A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. I the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] The power amplifier remains cooler and dissipating the developing waste heat in a specific direction gets easier. In general, setting up or mounting the power amplifier has to be done in a way that fresh air can enter unhindered at the front and exhausted air can exit at the rear. When installing the power amp in a case or rack system, attention should be paid to these details to provide sufficient ventilation. Allow for an air duct of at least 60 mm x 330 mm between the rear panel of the power amplifier and the inner wall of the cabinet/rack case. make sure that the duct reaches up to the cabinet's or the rack case's top ventilation louvers. Leave room of at least 100 mm above the cabinet/rack case for Since temperatures inside of the cabinet/rack case can easily rise up to 40 °C during operation of the power amp, it is mandatory to bear in mind the maximum allowable ambient temperature for all other appliances installed in the same cabinet/rack case. CAUTION: Blocking/closing the power amp's ventilation louvers is not permissible. Without sufficient cooling/ventilation, the power amplifier may automatically enter protect mode. Keep ventilation louvers free from dust to ensure unhindered airflow. Do not use the power amplifier near heat sources, like heater blowers, stoves or any other heat radiating devices. To ensure trouble-free operation, make certain that the maximum allowable ambient temperature of +40°C is not exceeded. Following section describes the four different OUTPUT settings of CPS amplifiers. In 2 Ohm mode the power amplifier reaches maximum output power having a load of 2 connected. For using VLD in a power amplifier with a Remote Control Module installed, please proceed as follows: · Use the DIP-switch OUTPUT (see page 10) to select DUAL or PARALLEL output mode for power amplifier channels to be operated in VLD mode. Use IRIS-Net (see page 15) to configure output power, impedance and High-Pass filters of individual channels. Detailed information on the configuration, control and monitoring of amplifiers with Remote Control Modules installed can be found in the documentation that comes with the IRIS-Net software application. the configuration of power amplifier channels is stored nonvolatile in the Remote Control Module. Please keep in mind that the VLD configuration in IRIS-Net only affects channels set to , , 2 /VLD" mode. The use of VLD considerably expands the adaptability of a power amplifier. Following table shows possible switch settings and corresponding delay times in seconds. Whenever possible, using balanced audio signal feeds at the input of the power amplifier is always preferred. Unbalanced connections should only be used if the cables are very short and no interfering signals are to be expected in the vicinity of the power amplifier. [. . . ] CAUTION: Each address may exist only once in a system. Address 0 (00 hex, delivery status) disables remote communication between the RCM-810 and the bus. The module does not appear in the system, even though it is physically connected to the CAN-bus. 3 STATUS LED The STATUS LED is for monitoring the communication on the CAN bus. [. . . ]
