Axiom Home Page Forums General Discussion Home Theater EP-600 Review thread.

Nat. I'm currently running 1 EP600, 2 EP500s and an Ultra in a quad setup. I've never had a problem with auto-start. The most important thing is to calibrate them properly. Also keep in mind the Axiom subs DSP chips react differently to single tone sine waves than analog subs when calibrating. For example some people report sudden surges in volume with slight changes in sub gain. It's easier to calibrate by raising gain above calibration reference then lowering sub gain at the processor/receiver to reference levels.

The trigger and XLR functions can be a bit confusing in the sub woffer manual. The following information is what I learned from Axiom folks about ten months ago when I was adding the second 600. So unless they have changed the software since that time, this is how the triggers should work.

A siganl sent to the trigger IN will fully turn the woffer on/off, this can be verified by the indicator light changing from green to red, or red to green. If one connects a trigger wire from the OUT to the IN on a second sub, then both will be controlled for the on/off operations.

As for an auto mode, my understanding at that time was the 500/600 do not have this function. They do however go into a low power usage mode after a period of time of not being active, using very little voltage, so leaving them on 24/7 is nothing to be concerned about.

Hope this helps clear up the questions.

Yes it does. Thanks to all.

This clears things up.

Well, this sound like the Sub to go for. I will talk to Axiom now to find some finer placement information and will probably order one when they come up with the real wood veneers (Feb / March).

Thanks to all.

Nat, I double-checked with Tom Cumberland, who engineered the amplifier:

The EP500/EP600 will easily handle 130 degrees F. Because it does not generate heat on its own, the ambient temperature is inconsequential. Also, CSA has done high temperature tests for this unit both in humid and non-humid conditions to verify its safety.

(CSA is like UL) So it looks good!

Thanks Amie.

I checked with JC@axiom with the same question. He replied with a similar answer


Quote:

Heat will not be a factor for the EP500 / 600. It has been tested by the CSA for room temperature exceeding 65 degrees celsius.It goes in a sleeping mode (power saving mode) after a signal absence of between 10 to 20 minutes. Back to operation is commanded through DSP software when an audio signal is perceived.

End Quote.


BTW: What is CSA & UL ?

UL

CSA

UL is Underwriter's Laboratory.

CSA is the Canadian Standards Association.

Both groups approve products which meet certain codes and standards of safety and health.

CSA = Canadian Standards Association

UL = Underwriters Laboratories -- not 100% sure, but I was told this started as a product evaluation lab for a collection of insurance companies and grew from there.

Thanks. So They are independant third party testers.

Excellent.

For the sake of completion of this thread with all EP 600 discussions, and to save the nice people in Axiom some more questions emails , please find the last email I exchanged with JC in Axiom relating to the EP 600 product.


Question 1: Through other owners of the EP600 on the Axiom Board forum, I found out that the EP 600 does not have an auto-on feature on detection of a signal detection. I live in a very hot country and am worried for the Amp of the sub to heat up when the temprature on the room raises. I understand that the sub goes into power saving mode when not in use for a while. How correct is this ? and is the sub likely to be affected by room temprature of slightly less than 50 centigrade (when not in use, but the switch is on) ?

Question 2: My room measurements are 18 feet X 14 feet X 10 feet = total area ~2600 cu feet. I know that the EP 600 will be an overkill for my room, but I like the idea of owning top of the range. My question is, will I be better off accoustically with the EP 500, or will the EP 600 fit well in my setup ? (my other speakers are the M80's+VP150+4 QS8).

There would be no acoustic benefit of an EP500 over an EP600 in your room.

Question 3: My Denon 3805 does not have separate crossover points for different speakers and it has a single crossover point. I know from reading some posts that the M80's can be crossed over at 60 or even 40, whereas the remaining speakers that I have require 80 of more crossover point. The Question is that, I am thinking about setting the M80's to Large in the 3805 and sending the full signal to the sub and setting the crossover of the sub to 40 hz and feeding it to the M80's. In addition, I will need to connect the Sub out from the 3805 to the new Sub. will that setup work fine or am I mising something ? Can the sub accept two inputs from the in speaker terminals and the sub line in ?

In your room, I would select small for all my speakers including the M80Ti. Select 80Hz at the receiver and select bypass on your EP600. You cannot simultaneously connect both the high level inputs and the line level input on your EP600. Use a subwoofer coaxial cable from the subwoofer output on your receiver to the line level input on your EP600. After you are familiar with the sound provided by these settings then you can try a 60Hz crossover setting in your receiver. Choose and keep the one you prefer.
