1. Ringkesan produk
Cocog digunakake ing transmisi loro arah (bisa dilindhungi undhang-undhang) lan ekualisasi sinyal transmisi trunk multi-kelas utawa jaringan distributif sing dibutuhake. Ngadopsi PHILIPS, NEC diimpor modul daya dobel. Pre-amplifier audio yaiku amplifier push-pull tabung gelombang mikro sing kurang swara kanggo njamin gain sing cukup. Nduwe 1 input lan 2 output, lan saben sambungan duwe proteksi over-current. Cabang output utawa distributiveness bisa diganti sawise iku. Ekualiser kaping pindho digunakake, saéngga nyetel flatness transmisi multi-kelas gampang lan trep. Attenuator lan ekualiser minangka plug-in, supaya pelanggan bisa milih gaya tetep utawa luwes. Daya saklar sing bisa dipercaya (utawa daya linear) lan desain anti banyu lan anti gludhug sing ketat njamin karya duratif sing mantep.
