- #1 [Qwea], 21-02-27 08:10請問各位師兄,我有一部AV擴音機,一部兩聲道擴音機,可否同時駁落一對喇叭,但只用其中一部機聽,因不想成日將D線,又拔又插,太麻煩,請指教,謝謝!
- #2 [audio338], 21-02-27 09:47建議用 閘刀開關,contact resistance 較低。
例如:正泰HS11-200/48B - #3 [kit271], 21-02-27 09:50洗唔洗禁誇張呀

- #4 [alexanderkoo], 21-02-27 09:51Only for fun, question being too difficult. Can't have your cake and eat it, too.
- #5 [audio338], 21-02-27 10:15閘刀開關有膠蓋的
- #6 [Edo], 21-02-27 10:33之前有人問過同樣問題!說實話懶就唔好多心,玩一套機就算啦!
一係就買個switcher
最後修改時間: 2021-02-27 10:34:35 - #7 [alexanderkoo], 21-02-27 10:55Simply buy the best affordable theater amp. Can use a good pre-amp for 2 channels.

什麼型號丶有沒有AV bypass - #9 [Richmond168], 21-02-27 17:45DIY 一個relay 組合。

Mechanically interlocked Telemechanique contactors, as used in Industry to avoid parallel operation of mains supply and generator supply.(used one source at a time) At least 32A for termination of rubber hose speaker cables. Inexpensive. One push button can changeover the devices.

Have fun

- #13 [Qwea], 21-02-28 01:28原來咁複雜,要加刀制,我重諗著是但著一部會無問題,同埋會唔會變衰聲。
- #14 [alexanderkoo], 21-02-28 07:39If it were pre-amp only, simply having bypass at the AV amp. but now, 2 power amps. That's why the suggestion of 4 pole 2 way switch or contactors for changeover.
Or simply connect the 2 channel amp for music, then as front speakers for 5.1/7.1 via processor(or from 5.1 channel blu ray player). The other channels of the AV amp used for centre and surround speakers.
- - #15 [吹吹水], 21-02-28 09:39你就甘接兩部機,你可以就下,不過燒左部機就唔好出聲
最後修改時間: 2021-02-28 09:40:44 - #16 [alexanderkoo], 21-02-28 09:54There is a price to pay, either before or after.
- #17 [254mm], 21-02-28 12:19如果識 Diy, 用 relay 整,不難。選擇 比电/唔比电 个relay, 就可以了。
- #18 [mm452], 21-02-28 14:04又出黎猪up
- #19 [徐福], 21-02-28 15:43樓主 ; 其實可參考管迷的喇叭切換器,自已DIY不難做,可用塑膠箱代替鐵箱。
