AV AMP 應該 set 6ohms 定 8ohms?
想問下Ching們，如果我d喇叭又有6 ohms 又有 8 ohms，咁我部AV Amp 應該set用 6ohms 定 8ohms的 speakers呢？前置：6 ohms (Monitor Audio RX1 Max, 80W)
中置：8 ohms (Monitor Audio BX Centre, max 120W)
前後surround：8 ohms(Mirage Nanosat Prestige, max 100W)
AMP: Yamaha 2067 如果我冇記錯, 應該係SET最低果個!!! You quick...quick..as "Mr. Yamaha" la{:1_253:} 回復 1# happypanda1666
yamaha有得set ohm 既咩 ?????
係邊度set ??

Advance setup 度有得set

Yes..ar...see...see..Menu{:1_351:} 6 ohms....{:6_211:} 即係set 6ohm 係好 d ??? 我比較相信鬼佬, 較6 ohm嘅話會大幅減弱power output, 所以set番去8 ohm會好啲:

Editorial Note about the Impedance Selector Switch
I recommend the "Minimum 8-ohms" setting even for 4-ohm speakers of moderate efficiency ( > 89dB SPL). Yamaha includes a" 6-ohm" setting to satisfy UL heat dissipation requirements when driving 4-ohm loads, as well as easing consumer concerns about driving low impedance loads. These switches step down voltage feed to the power sections which can limit dynamics and overall fidelity. My advice is to keep the switch set to "Minimum 8-ohms" regardless of the impedance of your speakers and ensure proper ventilation of the Receiver. To illustrate this point further, I have tabulated my measured differences between the 8-ohm and 6-ohm setting for driving 8-ohm and 4-ohm loads.
8-ohm setting: 134wpc into an 8-ohm load @ 0.1% THD; 210wpc into a 4-ohm load @ 0.1% THD
6-ohm setting: 95wpc into an 8-ohm load @ 0.1% THD; 180wpc into a 4-ohm load @ 0.1% THD 好似話除非部AMP好熱，否則keep住用返8 ohms既 setting係會好d。
