[. . . ] The following rule of thumb is valid to determine the number of power radiators required: For an area of 2 m2 one diode is necessary, that means one power radiator covers up to 24 m2 at stereo operation. [. . . ] The built-in power supply of the infrared transmitter is able to feed ei 9 h t 8Z11 012 directly. The number of the connected power radiators can be increased without limit. The input stage works as limiter amplifier giving the guarantee of an optimal amplitude for the built-in output stage - independent of the output level of the infrared transmitter. Mounting flexibility is given by means of a 3;g" internal thread. For portable use we recommend the table clamp MZT 237 or the floor stand MZ8 142. The power radiator is connected to the transmitter by means of a flexible control cable. [. . . ] The power radiator is connected to the transmitter by means of a flexible control cable. [. . . ]
