Axiom Home Page Forums General Discussion Technical Questions Ep600 Low Power Mode doesnt save power

Hello
I am on a power savings kick and hooked up a 12v trigger to my EP600. Also have a current monitoring system attached to breaker box on each circuit to see power usage in real time.

The EP600 light will turn from green to red when the receiver is turned off. However the power draw does not go down at all, well maybe a watt. If I turn the EP600 off the consumption drops by about ~20 watts.

Is the trigger really set to save power or is it just basically a mute circuit ? the manual leads me to believe otherwise.

Note I may have an older version of the EP600

thanks

from the manual. emphasis mine.

TRIGGER: Use of the trigger input is an optional hook-up. If your A/V receiver or A/V preamp-processor has a 12-volt trigger
output, you can run a 3.5mm connector cable to the subwoofer trigger input and your subwoofer will power on and off with your
A/V receiver or A/V preamp-processor. When the trigger signal is in the “off ” mode the LED will change from Green to Red and
the amplifi er will be switched to a low power consumption standby mode. If you have multiple subwoofers you can run a 3.5mm
connector cable from the trigger out on the first subwoofer to the trigger input of the second subwoofer.

Jim, I strongly recommend you turn your gear off. This will save the most energy and extend the life of your gear.

there has been a few conversations on this forum about the power being used, standby and the whole nine yards.

its very true that low power mode for electronics is a bit of a joke. I know that standby mode doesn't mean a whole lot to be able to get the energy star logo on the package. There are a few items that i have found in the quest to get the most out of my system without paying a fortune for the power costs.

first thing that i have found is the some of the smart switches are very good in providing a better standby option than i can get through the actual equipment. For some things its a bit harder as it stripping away the power consumption leads to more aggravation and chance for things not to work seamlessly (reduced WAF)

I currently have my FireTV, Anthem AVR and TV plugged into the wall full time with their standby as I haven't figured out any way to get the functionality I want with automation to power everything on and off in a controlled manner with these devices also being on a smart switch and themselves being powered off.

I have however gotten all my external AmpOne and ADA1500 amps sitting on a smart plug along with the EP500 and Active DSP for the LFR speakers. What I did find however in the process is that i require the EP500 and ADA1500 to also use the 12v trigger cables to first put them into the standby mode before I shut the power off otherwise I will get a nice loud pop sound from the speakers. Not what you'd want. But using some smart automation I have setup a 10 second delay for the power down on the smartswitch to allow the units to safely get into the standby mode with the 12v trigger before I cut the power off. I have also put into the automation the order that the units will power themselves back on so that the amps can turn on back into standby mode and be ready powered before the AVR gets turned on by my FireTV Cube and the 12v trigger comes back on. it really is a good method all around.

Thanks for the reply. I guess that is what I am finding out. I have been using some https://shelly.cloud/ shelly smart relays in other places. However the TV and Receiver are networked so I can use https://www.home-assistant.io/ Home Assistant to control them. hate to add a relay just for the sub.

Overall <20 watts for the EP600 idling isnt bad. I just had expectations that the 'low power consumption' mode would do something besides change a light from green to red. maybe red uses less watts. haha

I'm pretty much doing a 180 . Always wanted everything ready to go. Now with energy/all costs up I am revisiting my desire for instant gratification.

I coulda swore my earlier EP500 went into power savings without a trigger. The current manual shows a trigger. I got the EP500 new around 2006 and had to have the electronics replaced around 2011. It went out again in 2021. Thats when I got a used EP600. So yea Mojo, maybe could extend the life of the device but manually flicking the switch aint gonna happen.

seems pretty dead around here. My brother was able to sell his 2008~ axiom setup recently after selling his house. It was m60 / ep500 / vp-150 / 4@qs8 . He had the real wood veneer. got around $900

Pre-v3 DSP subs auto-mute and use less power when there is no signal.

This is one of my areas of interest. Luckily, I have a few projects in the works which I can extend to power up/down the axiom amps and subs. Note: the need to coordinate power down with the triggers to prevent transients. Also one needs get a handle on any shortening of components life (and how to mitigate it).

That said, it's best if Axiom incorporated this thinking into future products (minimizing standby power).

The question is "are you willing to pay for it" ... as the engineering and added complexity costs would need to be spread over the number of units they sell. That may be a significant number ...

With the global focus on sustainable practices, i.e. ESG, I don't think companies can avoid this any longer.

The product design is actually quite simple.

Instead of the present two-position, on/off rocker switch, a three-position switch can be used. These positions would be off/on/stand-by.

In off and stand-by, this design would draw zero quiescent power. I wouldn't even use an LED to indicate stand-by.

When the stand-by is externally triggered, the circuit would draw no more than 1W at 12V. That 1W would be used to power an electromechanical relay.

The stand-by circuit could be designed to trigger and de-trigger off 12V but then latch and unlatch the relay from 120VAC. This would unload the trigger circuit from the constant load. I'm not sure though if this would be beneficial.

Edit: Not sure there's even a need for the off position.

My subs are behind screen wall. Im fucked.

Trevor, wiring both a power switch and trigger in front of your wall is just cabling
