When using the Trigger, the EP500 does not always wake up properly. The LED on the back switches from red to green however the sub output level is severely reduced. In other words it is working but at say 20% volume. The only way to recover is to cycle the power on the EP500.

The issue is intermittent and the last test I did I found that the issue occurred after 8 days with an average of 25 power cycles (i.e. turning on the home theater).

I have tried with two Denon receivers and an external Emotiva trigger box.

It's not a big deal as the idle power draw is real low (~10 watts) but it would be nice if it worked. Incidentally, I use the trigger on my ADA1000 without problems.

Andrew,
i got 2 subs: one PC12 Plus (Bash) and
one PC13 Ultra (Sledge) connected through a "Y" adapter at the AVR.

Levels: 12 Plus: 10 o'clock
13U: -12 dB.
The 13 Ultra is calibrated to output about 5 dB higher SPL than
the 12 Plus for the same signal input.

The 12 Plus is tuned to 16 Hz
The 13 Ultra is tuned to 10 Hz (2 ports plugged and HPF filter set at "sealed").

phase: 12 Plus: 0
13 Ultra: 180

Connection: RCA

AVR: Marantz SR5005

Speakers: M80
Xover: 64-80: can't decide which is best...

Trim levels:
M80: L: -3
R: -2.5
Subs: -6.5 (run 3 dB hot)

I haven't even looked to see if there are triggers anywhere in my system...

This is the same issue i was having... i discussed it with Brent, i made the decision to just let the amps idle as they were not "turning on" even though the LED was indicatig the circuitry had switched from off to on. i.e. red to green.... i verified the trigger being used was working by using it on one of the amps, the trigger in question works just fine. I was getting 0 out put though, not reduced output. As though the amp had not switched on at all....

I keep meaning to double check in the evening but I never do so here is what I can recall.

What Axiom subwoofer(s) do you own?EP500

Where do you have the Level, Frequency, Phase, and Subsonic Filter (if applicable) controls set?Level = 7-8 oclock, Frequency= bypass on sub, 80 on receiver, phase=normal

How are you connecting your signal source to the subwoofer (RCA/XLR/High Level)?
RCA

What receiver/processor/pre-amp/integrated amplifier are you using?
Denon 3608


What are you using for your main speakers?
Axiom M60

Where do you have the crossover frequency and trim levels set in your processor/receiver for your main speakers and your Axiom subwoofer?
80 Hz all speakers.
Center +1.5, rMain -.5 rSuround -1.5, Sub -2
Note on my sub trim: This results in the sub running hot in most of the room but still a bit weak in my main seating position. If I try to even out the seating position, it's too boomy in the rest of the room. I blame the room, not the sub.

Are you using the trigger on your subwoofer?
No

What Axiom subwoofer(s) do you own?
=> EP-500

Where do you have the Level, Frequency, Phase, and Subsonic Filter (if applicable) controls set?
=> Level is fairly low (can't see it easily), all other parameters at defaults (no subsonic on my unit)

How are you connecting your signal source to the subwoofer (RCA/XLR/High Level)?
=> XLR

What receiver/processor/pre-amp/integrated amplifier are you using?
=> Anthem Statement D2v

What are you using for your main speakers?
=> M-80s

Where do you have the crossover frequency and trim levels set in your processor/receiver for your main speakers and your Axiom subwoofer?
=> Mains at 60hz, subwoofer at 100hz (brickwall at 100 in my unit)

Are you using the trigger on your subwoofer?
=> YES, a lot

FEATURE THAT WOULD BE NICE:
Since I listen to a lot of SACDs that don't filter low frequencies, many recordings have annoying noises below 20hz. It would be nice to have a processor-controlled subsonic filter trigger (a second 12V trigger for subsonic filter would be fine).
Other wise some USB controls via PC interface would also be nice.

Loc: It's all about the location.
My HT is in limbo presently(darn renovations!)

I have a Paradigm DSP3400, I remember having it set at 1/4 gain, can't recall what it was crossed over at 40-60hz, run by Denon 2809 with M80s. One feature I really like is the auto on/off.

12:00 o'clock, bypassed (120), 180, N/A

RCA

Denon 2808

What are you using for your main speakers?

M80

Where do you have the crossover frequency and trim levels set in your processor/receiver for your main speakers and your Axiom subwoofer?

80 Hz, Trim was set using spl meter and test tones. Sub trim was adjusted up until the signal going into my Feedback Destroyer was just below clipping at reference

Are you using the trigger on your subwoofer?

Yes, Great feature!

I use the Feedback destroyer for subwoofer EQ. Filters were set using REW. With room gain, I get a response flat down to 21 Hz (no low end boost)
