請教 JL Audio 的 Automatic Room Optimization
因為 AV Amp 會跟據所有聲道喇叭低頻表現的平均數據，自動釐定好將 High Cut Point 以下的低頻段由 Woofer 輸出。那麼 JL Audio Woofer 進行 Automatic Room Optimization 前，LP feq. 是否應該 set 去最大的 130Hz？

RECOMMENDED SETUP PROCEDURES
On the Fathom’s Front Panel:
Please turn off the home theater receiver or preamp/processor to make these
adjustments.
1. “Power” Switch
Flip each Fathom’s “Power” switch to the “On” position.
2. “Lights” Switch
Flip each Fathom’s “Lights” switch to the “On” position. If you don’t see any
lights on the front panel, you may have forgotten to plug the Fathom in or
there may be a problem with the electrical circuit.
3. “Input Mode” Indicator Lights
If you are using a single Fathom, confi rm that its “Input Mode” indicator light
is on the “Master” position. If not, you will need to access the upper “Input
Mode” switch on the rear panel of the Fathom.
If you are using multiple Fathoms in a Master/Slave confi guration, confi rm
that the unit connected directly to your receiver or preamp/processor is
indicating “Master” on its “Input Mode” lights and that all other units are
indicating “Slave” on their “Input Mode” lights. If not, you will need to access
the upper “Input Mode” switches on the rear panels of the Fathoms.
4. “Level Mode” Switch
Flip the master Fathom’s “Level Mode” switch to the “REF” position.
5. “LP Filter” Switch
If your home theater receiver/processor is handling bass management
(speakers set on “small”) or if you are using an outboard crossover/bassmanagement processor, fl ip the master Fathom’s “LP Filter” switch to “OFF.”
If not, select the “12 dB” position.
6. “LP Freq. (Hz)” Knob
Rotate the “LP Freq.” knob to the “80 Hz” position.
7. “e.l.f. trim (dB)” Knob
Rotate the “e.l.f. trim” knob to “0”
8. “Polarity” Switch
Flip the “Polarity” switch to “0”.
9. “phase (deg.)” Knob
Rotate the “phase” knob to “0” degrees
10. A.R.O. Defeat Switch
Press the A.R.O. defeat switch so that the red light in the
switch remains lit. chhanthony 發表於 2013-7-24 15:27 static/image/common/back.gif

Thank you chhanthony兄，咁喺80Hz做完ARO後，是否將LP feq.調回Max 130Hz，繼續做AV Amp的Auto EQ？ 如果你已經用咗AV AMP去做crossover嘅工作，咁係JL front panel個LP Filter制就可以用"off"
咁正常“LP Freq. (Hz)” Knob校幾多都唔會再起作用，但保險啲可以將“LP Freq. (Hz)” Knob校到最高"130hz" chhanthony 發表於 2013-7-24 21:41 static/image/common/back.gif
