Wifi router 與 HiFi

Audiophilelp

今日多手再玩下個舊phono，著機發現有"撘撘撘"雜聲來自phono，初時以為hum聲但hum不是搭搭聲而是嗚嗚聲，試過移動啲線和phono，可以減少或增加雜聲但不能完全清除。phono下層是wifi router，相隔只有半尺，試過移動antenna，又是有影響，再將router息機，即刻靜晒，聲音靚晒，將wifi router 搬去遠處，問題解決

結論：wifi router 是衰聲來源

Couldn't agree more

I have the same experience as you when I switch off/move away the the wifi router from the tube phono amp, all the "tat tat" sounds is gone and the background becomes dead silent.

Yes i find my system sounds better too without wifi signal at home, even my router is already very far away from my system. Sound is more relaxed and natural. So i turn off router everytime for serious listenimg.

咁我呢d要靠router傳遞訊息作訊源的點算？
個wifi要來做ipad 音響搖控，唔知有無方法

對，就係要玩FAS/streaming冇左router唔得，只好將佢搬遠D，另外，聽黑膠嘅時候息左佢

任何音響羡品也是愈少干擾愈好。簡單如關燈音色也好些。

咁其實歸根夠底，袞聲原因是Wifi Wireless Signal Interference, router本身，or power supply of wifi router, etc...?

我試過電視高清盒亦有此情況！

息埋手機,電腦同所有用電子牛與音響無關嘅家庭電器,即時好聲到你唔信

到底是不是 Phono Amp/LP turntable or related gears 特別sensitive呢？上面 Ching話平時冇聽LP時冇出事..."今日多手再玩下個舊phono，著機發現有"撘撘撘"雜聲來自phono...再將router息機，即刻靜晒，聲音靚晒，將wifi router 搬去遠處，問題解決" 所以phono & Wifi router 之間應該有事發生.

其實會唔會同phono cables有關?

hehe...以上只是mo liu 諗下! 可以不理

對！phono是非常敏感的，phono cable，phono amp，phono power 全部都有影響，只是今次干擾phono的是wifi router，其他器材冇禁明顯

咁若果WIFI ROUTER用乾電供電或經隔離牛或三相電中唔同相供電會唔會有改善？

仲有室內無綫電話都係雜聲來源⋯尤其是對蛋機

都唔一定，我對有源喇叭一開 router 都有撘撘聲，而且試過攞開遠d 都還有少少，只有熄機

由於我個 WiFi router 可以 support 2.4ghz/5ghz, 我試過關掉2.4ghz 只用 5ghz 都會靜哂，估計應該同個電池波訊號有關

How about all other wifi related equipments? If you had them in the house, did you also switch them off as well?

BTW, I would imagine the problems related to the wifi router are related to the power supply of the router & the location of the WIFI routers. As per the previous messages, once the wifi router has turned off, issues were all gone! But even the wifi router is further away from the hi-fi system, the issue is still there but the symptoms are not as bad!

IMO, if you really want to solve the problem, you may have to test every possible cause one by one! Like just have one wifi router installed. NO other wifi equipments are power on! Then Check the symptoms again. Then try to put the wifi router as far away from the hifi system as far away as possible. Lastly, turn it off!

I think try to perform those tests to see if you could figure out who is the suspect!

Just my own opinions, pls ignore it if you think they aren't make any sense!^.^

係我個情況來講，都幾肯定係個電池波問題了，我把所有屋企電器都關掉，只開wifi & 有源喇叭，前級， cd player 都無開 (router & 喇叭電源位是分開的) 不論 router 離喇叭有幾遠都好，始終有撘撘聲，我嘗試把 router 放置在喇叭附近，d 撘撘聲大到企遠些小都可以聽到

但未換喇叭前冇咁嘅情況出現過，估計 router 同某些電器電池波有衝突時就會有咁嘅情況

即係如果turn off router 就可解決問題！如果係咁，一係聽歌時關掉wifi router. 一係就用LAN cable 駁電腦&modem while listening to music.

另一個方法係買個有開關制既wifi access point駁router，將router既wifi長關。如需要wifi先開access point。NAS同cas/fas player用LAN cable駁。咁就唔會因為熄左router而無得玩cas/fas。

In my case when the wifi router is moved away from phono(>1m) the noise becomes inaudible. Fortunately my other gears are not affected by the router.
