[. . . ] SZI 1015 IR Audio Transmission Technology | Modulators/Radiators General Description The SZI 1015 is a 2-Watt radiator with a coverage area of up to 400 m2. The radiator is switched on and off automatically by the modulator's RF carrier.

It has a coverage area of up to 400 m2 in single-channel operation and can be switched between mono and multi-channel operation. Please note that in multi-channel mode, this maximum coverage area decreases proportionally with the number of channels transmitted. The RF signal from the modulator is fed to the radiator via a BNC socket (1) and can be daisy-chained to other radiators via the BNC RF output (3). Alternatively, the modulator's RF signal can also be fed to the barrier strip. Terminal 5 is the RF input and terminal 8 the RF output for daisy-chaining the signal to further radiators. [. . . ] You should also keep in mind that signals can cancel out when cables are very long and coverage areas of radiators overlap. In order to avoid reception problems, you should use both RF outputs of the modulator and set up two RF chains (see also Planning Theory). 1 1 2 3 4 5 6 7 8 23 4 5 6 7 8 RF input (BNC) Mono/multi switch RF output (BNC) Thread for mounting RF input terminals DC input terminals DC output terminals RF output terminals Sockets and controls of the SZI 1015 50 50 Creating RF chains [. . . ]
