SPECIFICATIONS
The EM 3731/3732-II is a true diversity receiver that is characterized
by high transmission reliability, exceptional audio quality and simple operati-
on. The frequencies are adjustable in 5 kHz steps. Special features include the
DSP-based HiDyn plus expander and its transformer-balanced audio outputs.
The EM 3732 COM-II is also equipped with a command audio output. The EM
3731/3732-II is available in L, N and P frequency range variants and as a twin
receiver (EM 3732-II) or single receiver (EM 3731-II).
