I forget where I got this from, maybe Brian?
I've never used these particular settings as I use the bass management in my Denon receiver, so YMMV.
Also, assuming you're using a PEQ3 amp, if you use the LFE input, you disable the Phase and Crossover controls on the sub. Something to keep in mind if your preamp doesn't provide any bass management controls or room correction.
3. Recommended initial 2-channel setup (without AVR or pre-processor)
The standard PEQ3 amplifier does not have HPF output. This means that the front speakers will run full range.
The following setting also assume the subwoofer is placed at a distance to the listener
similar to those of the front speakers so no additional delay time adjustment is needed.
Recommended plate amplifier settings (from top to bottom, left to right)
1. Input: LINE-IN
2. PEQ: OFF
3. Gain: 0db
4. Bandwidth: middle position
5. Frequency: middle position (40 Hz)
6. Delay/phase: 1 o’clock – sealed speakers, 10 o’clock for ported front speakers.
7. Crossover: Set Crossover knob to match natural bass extension of the front speakers.
8. Volume: middle position (12 o’clock)
9. LOWPASS filter: 5” woofers - 80hz/24, larger speakers - 50hz/24.
10. Rumble filter: OFF/1 for one port configuration and ON/2 for 2-port configuration
11. Extension filter: 14 Hz high damping for articulate sound and 14 Hz low damping for full bodied HT sound.
Hope that helps.
