Uhlelo Lwe-PA Lwenethiwekhi – I-Network Preamplifier (2U, Okokufaka Okungu-10, Okukhiphayo Okungu-4, 1000W)
Incazelo Yomsebenzi Womkhiqizo:
1. Iphaneli emnyama ye-aluminium ye-2U ephezulu, ukufakwa kwe-rack-mount.
2. Uhlelo lwe-Linux, ukusebenza okuzinzile nokusheshayo.
3. I-DSP software audio decoding, ukudluliswa kwenethiwekhi kwekhwalithi ye-CD engu-16‑bit stereo.
4. Yamukela imiyalezo yesistimu, isekela ukulawulwa kwevolumu ukude.
5. Kusekela ukuthuthukiswa okukude kwesikhulumi.
6. Kusekela ukusakazwa kwezindawo namaqembu okulawulwa yisikhulumi.
★ 7. Iziteshi ezimbili zokuphathwa kwamandla ezihlakaniphile ezakhelwe ngaphakathi, ukuphuma okuphelele kufika ku-1000W.

10. Izimfuno eziyishumi: 5 imic, 3 umugqa, 2 eziphuthumayo.
11. Ivolumu ezimele yesiteshi ngasinye sokufaka.
12. Ivolumu enkulu, ukulungiswa okuzimele kwe-treble/bass.
13. Umsebenzi wokuthulisa, ukunciphisa okuzenzakalelayo kuya ku-30dB.
14. Okukhiphayo okungu-4 kwe-AV, xhuma kufika kuma-amplifier amandla angu-4.
★ 15. Isishintshi semodi yokuthulisa (sivaliwe/sivuliwe njengoba kudingeka).
★ 16. Isishintshi somhlaba/sokwezela isignali sokulungisa amaphutha endaweni.
★ 17. Izishintshi ezintathu zokuthola (0.775V/1V/1.5V), okuzenzakalelayo efektri kungu-0.775V.
★ 18. Ukufakwa kwamandla esignali kanye nokuphuma nesimo esakhelwe ngaphakathi esinamandla sokushintsha imodyuli.
★ 19. Okukhiphayo okulawula ukubiza izikhulumi okungama‑3‑wire (akudingi i-DC24V, amayunithi okubiza izikhulumi angenamkhawulo).
★ 20. Ihambisana nezilawuli zokukhala zezintambo ezi-4 (kudingeka i-DC24V yangaphandle).
21. Isekela i-DHCP, iyahambisana nanoma iyiphi inethiwekhi (multicast/unicast).
22. Ukuhlukaniswa kwenethiwekhi okwakhelwe ngaphakathi nokuvikela umbani.
★ 23. Ukuphakela amandla okubili (DC24V & AC100‑240V), ukushintsha okuzenzakalelayo kuya ku-DC yokugcina.
1. Iphaneli emnyama ye-aluminium ye-2U ephezulu, ukufakwa kwe-rack-mount.
