[. . . ] The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated , , dangerous voltage" within the product's enclosure that may be of sufficent magnitude to constitute a risk of electric shock to persons. install in accordance with the manufacture's instructions. Do not install near heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or the grounding-type plug. [. . . ] For fixed amplifier installations in a device control room that incorporates a central air-cooling system or air conditioners, calculating the maximum heat emission may be necessary. They are not running permanently but the running speed of the fans is controlled continuously depending on the ambient temperature. That in return ensures very silent running during idle state. The temperatures of the power amp`s channels are registered and monitored separately. The MODE switch on the power amp`s rear panel defines how the audio inputs handle the input signals. In the following description of the modes DUAL, PARALLEL or BRIDGED the generic letters A and B are used for the two audio inputs of a MODE switch (e. DUAL In DUAL mode, the two channels of the power amplifier work independent from each other. This mode should be used if a high number of speaker with medium or low power rating should be driven in low impedance mode (LZ). In 4 Ohm mode the power amplifier reaches maximum output power having a load of 4 connected. Up to 2 cabinetts having a impedance of 8 each can be driven by each amplifier channel. This mode should be used if speakers with high power rating (e. Subwoofers) should be driven in low impedance mode (LZ). The 70 V mode allows connection of 70 V loudspeaker lines (Direct Drive) in high impedance mode (HZ) without using output transformers. In this case the maximum number of loudspeakers connected to an output channel is only limited by the amplifier`s output power (500 W for CPS4. This mode should be used if the distance between amplifier and speaker is larger than 50 metres (approx. 150 feet) and/or a high number of small speakers (e. The 100 V mode allows connection of 100 V loudspeaker lines (Direct Drive) in high impedance mode (HZ) without using output transformers. In this case the maximum number of loudspeakers connected to an output channel is only limited by the amplifier`s output power (500 W for CPS4. This mode should be used if the distance between amplifier and speaker is larger than 50 metres (approx. 150 feet) and/or a high number of small speakers (e. 3 shows all possible combinations of output power and connected load for power amps operated in low-impedance mode. 5 it is possible to freely select the output power in a range between 100 watts to 500 watts for loads ranging from 2 ohms to 10 ohms per channel. [. . . ] The LED blinks rhythmically every 3 seconds, when the module's address is set to "00", which means that it is disconnected from the CAN bus and software control. The LED blinks rhythmically in intervals of one second, when an address in the range of 01 to 250 has been assigned to the module and there has not yet been any activity on the CAN bus. As soon as communication on the CAN bus is recognized, the LED lights for at least 100 ms, when the power amplifier sends data on the CAN bus. 4 REMOTE CAN BUS Connection The RCM-810 module provides two RJ-45 sockets for connecting to the REMOTE CAN BUS.
