Uma izipikha zingasebenzi ngendlela elindelekile - ikakhulukazi ezikhiqiza umsindo ongafuneki, ukuhayiza, noma umsindo - akuthinti nje ikhwalithi yomsindo, kuthinta indlela abantu abazizwa ngayo ngawo wonke umuzwa womsindo. Kusuka kumsindo wasekhaya kuye kumasistimu ekheli lomphakathi lezentengiso (PA), izinkinga zomsindo zingabukela phansi ukusebenza kahle nokucaca. Kulesi sihloko, sizochazakungani izikhulumi zibhuza futhi zihayize, bese wethula ngokwemvelo ukuthi kanjaniImikhiqizo ye-PA ye-VNETPA yobungcwetizakhelwe ukuletha umsindo ohlanzekile, onokwethenjelwa-ezindaweni zomhlaba zangempela.
Kungani Izipikha Buzz?
Isipikha esihayizayo noma esivungamayo singaphezu kokucasuka - siwuphawu lokuthile okuphazamisa ukudluliswa komsindo okuhlanzekile.
Izinhlobo Ezivamile Zemisindo Yesipika Engafunwa
Nazi izinhlobo ezimbalwa zomsindo abantu abavame ukuwuzwa:
● Ukubhuza:Umsindo oqhubekayo onephimbo eliphansi noma eliphezulu ongavela ekuphazamisekeni kukagesi noma ekuxhumekeni okubi.
● I-Humming:Imvamisa ezinzile-imvamisa yokuvungama, ngokuvamile kusukela ezindabeni zaphansi noma ukungafani kwezintambo.
● Kwakhe:Umsindo ocijile, -ofana nonganyakazi ongase uvele kumakhebuli angavinjiwe noma amasignali akhuliswe ngokweqile.
● Ama-Pops & Crackles:Imisindo esheshayo, ephuthumayo ebangelwa ukuxhumeka okuxekethile noma izintambo ezigugile.
Ibangelwa Yini Le Imisindo?
Ukuqonda umsuka kukusiza ukuthi uxazulule inkinga ngempumelelo - ikakhulukazi ekusetheni umsindo okuphrofeshinali:
Ukuphazamiseka kukagesi nogesi
Amadivayisi aseduze afana namafoni, izibani ze-LED, noma-amarutha e-WiFi akhipha izinkambu ze-electromagnetic ezingahlanekezela amasignali omsindo uma izintambo zingavikelwe kahle.
Izinkinga ze-Ground Loop
Uma izingxenye zomsindo eziningi zixhunywe emithonjeni yamandla ehlukene, iluphu yaphansi ingakwazi ukudala umsindo ongaguquki ngaphandle kokunaka ivolumu.
Ikhwalithi Yekhebula Engalungile
Ikhwalithi ephansi-yezintambo noma amakhebuli alimele awanazo izivikelo ezanele, okuwenza abe sengozini yokuphazamiseka nomsindo.
Real-Ukulungiswa Komhlaba
Nazi izinyathelo ezisebenzayo ezithuthukisa ukucaca komsindo kakhulu:
● Sebenzisa-izintambo ezivikelekile zekhwalithi ephezulu- lokhu kuvimbela amasiginali angaphandle ukuthi angene endleleni yomsindo.
● Xhuma izingxenye endaweni kagesi efanayo- lokhu kunciphisa i-ground loop hum.
● Qinisekisa amandla ahlanzekilengezivikeli zokuhlinza noma izitolo ezinesimo.
● Gcina ukuhleleka okuhle kwekhebula- gwema amakhoyili aqinile noma amakhebuli awela izintambo zikagesi.
Lezi zindlela zibalulekileprofessional PA izinhlelo, lapho ukucaca komsindo kubalulekile kuzimemezelo, ukusakazwa, noma umculo ongemuva.
I-VNETPA: Izixazululo Zomsindo Ezichwepheshile Ezinciphisa Umsindo
Manje njengoba sesiyiqonda imvelo yomsindo wesipikha, ake sibheke ukuthi kanjaniI-VNETPAibhekana nalezi zinkinga ngedizayini ehlakaniphile nobunjiniyela bekhwalithi.
Mayelana ne-VNETPA
I-VNETPA ingumkhiqizi wemishini yomsindo ochwepheshe onguchwephesheIP-ikheli lomphakathi elisuselwe ku-IP, izikhulumi ezihambisana ne-VoIP/SIP, nakho konke-kumasistimu{2}}e-PA eyodwa. Le mikhiqizo yakhiwe kucatshangwa ngenethiwekhi eqinile nokusebenza komsindo, iletha ukucaciseleka okuthembekile kwezikole, amahhovisi, izimboni, amaplaza, nokuningi.
Imikhiqizo Eletha Umsindo Ocacile
Nansi eminye imikhiqizo emele i-VNETPA ohlwini lwe-VNETPA - ngayinye yakhelwe ukugwema izingibe ezivamile zomsindo njengokubhuza:
Izikhulumi zekholomu ye-IP
Izipikha ze-PA zekholomu ye-VNETPA ziza ngezindlela ezihlangene ezinoxhumo lwenethiwekhi oludidiyelwe. Lawa mamodeli asekela i-SIP ne-PoE, enza ukufakwa kube lula futhi aqinisekise ukudluliswa komsindo wedijithali okuhlanzekile ngaphandle kwekhebula ye-analog enkulu.
Kungani kubalulekile:Inethiwekhi-yomsindo osuselwe kunethiwekhi wehlisa ekonakaleni kwesignali kanye nokuphazamiseka uma kuqhathaniswa nokugijima okude kwe-analogi - okuyimbangela evamile yokuvungama noma ukubhaza.
IP Horn Izipikha
Izindawo zangaphandle nezimboni zivame ukubhekana nokuphazamiseka kukagesi nomsakazo. Izipikha zempondo ze-VNETPA ze-IP zenzelwe ukuphatha izimo ezinzima ngenkathi kugcinwa ukucaca:
● Amandla e-PoE phezu kwekhebuli yenethiwekhi eyodwa
● Ukuhambisana kwephoyinti lokugcina le-SIP
● Yakhelwe-ngokukhulisa idijithali
● Ilungele izindawo zokugcina izimpahla, amakhampasi, nezindawo zokupaka.
Kungani kubalulekile:Ukulethwa kwedijithali okuhlanganisiwe nge-PoE kugwema umzila ongcolile wekhebula lamandla nomsindo - okunciphisa ithuba lezinkinga ze-ground loop ezibangela ukubhuza.
IP Ceiling & Wall Izipikha
Ezimweni lapho ubuhle nokufakwa okubanzi kubaluleke kakhulu, izipikha zesilingi nezindonga ezine-SIP kanye nosekelo lwe-VoIP zitholakala:
● 8W kuya ku-15W izixazululo zomsindo zenethiwekhi
● Ukusekelwa kokucushwa okukude nokuphathwa
● Hlanza indlela yomsindo wedijithali iqinisekisa ukuthi umculo wangemuva nokupheja kucacile futhi kuzinzile.
Kungani kubalulekile:Amasistimu omsindo wenethiwekhi yedijithali anciphisa ukuba sengozini yomsindo wemvelo kanye nezindaba zekhwalithi yekhebula, izimbangela ezivamile zokuhayiza noma ukuhlanekezela.
Imicabango yokugcina
Umsindo wesipika ongafuneki uyinkinga evamile - kungakhathaliseki ukuthi usekhaya noma ezindaweni eziyinkimbinkimbi ze-PA. Ngokuqonda izimbangela eziwumsuka ezifana nokuphazamiseka kukagesi, izinkinga zokubeka phansi phansi, nokuklanywa kwekhebula okungekuhle, ungathuthukisa kakhulu ukucaca komsindo. Izixazululo zobungcweti ezivela ku-VNETPA - ezinomsindo wenethiwekhi, usekelo lwe-PoE, nokuhambelana kwe-SIP - zakhelwe ukunciphisa izinkinga ezinjalo zomsindo kuyilapho zinikeza ukuguquguquka, ukwethembeka, nokusebenza okuhle kakhulu komsindo.
