Axiom Home Page Forums General Discussion Advice from Axiom Owners Sub/AVR Volume and dB level settings?

Jack,

It's not as I say about the auto turn on, it simply can not be a factor if it does not exists.

And I say, at least with the early models, it DID have an auto turn on. I have witnessed (and solved) the problem with an EP500 and a 3805. The 3805 was set to -12, and the sub would not turn on until the volume was blasted. Like I said, they may have made a design change, but I wouldn't really want to try it on a long term basis.

I am going by Axioms own instructions. At no time do they discuss an auto turn on. If there is then I stand corrected

Step 5:
ON/OFF AC POWER/VOLTAGE SETTING: Your subwoofer is supplied with a pop-out voltage regulator set for use with 100 - 120 volts from the A/C line. It can be easily removed and turned over to set your EP500 or EP600 to 220 volts from the A/C line.

Once you have made appropriate connections from the A/V receiver or preamp/processor to the EP500 or EP600 and set the voltage regulator to the proper voltage, find a nearby AC wall outlet and connect the main power cord to the three-wire socket at the bottom of the control panel. Move the power switch to the ON setting and the LED POWER indicator should glow Green. Leave the switch at the ON setting unless you go away for an extended period. Moving it to OFF will shut down all power to the subwoofer

I'm confused. Didn't you say that there is no auto turn on factor with the 500? All I said was that "as you said," there is no auto turn on factor. I was agreeing with you.

Ken, There well may have been a change, but I seem to remember that it was said the 500 and 600 are always on, drawing very little power when inactive. I can't say for a certainty, because my 500 is plugged into a timed outlet on my power center. When I turn off my receiver, all power to the 500 is turned off. So, my 500 actually IS off when not in use.

I must have misinterpreted your post Jack, please accept my apology.

Guess we're going to have to rely on the kind auspices of the Axiom staff to resolve this one. Then again, the sub I am thinking of eventually got sent back because of other problems. So perhaps this was a symptom.

Note Gene DellaSala's comments re auto-on in his EP500 review .

OK, I'm obviously wrong. Makes the behavior of that sub really odd, though. Sorry, Wid.

Ken:
I don't see this as an argument, (but a discussion of a curiosity!), so I'll throw my two cents in:
I'm 95% sure I remember a couple of posts "way back when" where people were concerned about their sub not "turning on" and the suggestions of bumping up the receiver's sub level were successful in "waking up" the sub.

Can't say that I know it was a 500 that was being discussed those times, but I'll throw it out for what it's worth.

I'm not so sure you are wrong, Ken. Though it's a little confusing, based on what Gene had to say, it seems like we're BOTH correct.

"After several minutes of idle, I noted the EP500 back panel light remained illuminated green, indicating amplifier power was present. I questioned Axiom about this and they informed me there is no Auto On/Off feature on this sub, unless you utilize the 12V trigger connection. This was a concern to me at first until Axiom informed me the sub goes into auto mute mode when no signal is present, thus the power consumption is negligible since it’s a Class D amplifier design."

Hopefully someone will be able to clarify the difference between "Auto On/Off mode," and "auto mute mode." Regardless, if there is an "auto" mode of any sort, doesn't that imply the need of a signal to "wake" the sub from that mode? If so, then Ken is correct when he says too weak a signal may not "awaken" the sub. On the other hand, according to Gene, Wid and I are correct that there is no "auto on/off mode."

Well! I'm certaiinly glad we've cleared up THAT issue! DOH!!!!!
