Product Description
1. Chigadzirwa Summary
Yakakodzera kushandiswa mune bi-directional kutapurirana (inogona kuchengetwa) uye chiratidzo kuenzana kweakawanda-kirasi trunk kutapurirana kana yakakwirira-inodiwa yekugovera network. Adopt PHILIPS, NEC yakaunzwa kunze simba madouble modules. Odhiyo pre-amplifier yakaderera-ruzha microwave chubhu kusunda-dhonza amplifier kuti insure yakakwana kuwana. Iyo ine 1 yekupinda uye 2 zvinobuda, uye imwe neimwe yekubatanidza ine pamusoro-ikozvino kudzivirira. Bazi rinobuda kana kugovera kunogona kuchinjwa kuchitevera. Kaviri-equalizer inoshandiswa, saka kugadzirisa akawanda-kirasi kutapurirana flatness kuri nyore uye kuri nyore. Attenuator uye yakaenzana iplug-in, saka vatengi vanogona kusarudza yakagadziriswa kana inogadziriswa maitiro. Yakakwirira-yakavimbika chinja simba (kana mutsara simba) uye yakasimba isina mvura uye inopokana-kutinhira dhizaini inochengetedza yakatsiga basa rekuita.
