For connection, part of the sheath of a co-axial cable must be removed, then about 1 cm of the neutral conductor must be stripped. The copper braiding is then twisted and inserted into the frame earth terminal and the neutral conductor into the terminal next to it (see drawing). When connecting the last radiator of your RF chain, do not forget to use a 50 terminating impedance. The modulator's DC supply voltage is also present at terminals 11 and 12. The SI 460 can thus power up to two SZI 1015 radiators or a single SZI 1029-24 radiator via a two-core cable. You can also use co-axial cables with additional conductors for direct current, e. g. Your local Sennheiser dealer will be delighted to supply you with more information on this easy installation method.
