Denon AVR-X3600H Power

I recently got myself a Denon AVR-X3600H that is driving a 5.1 system using Adam T7V / T5V active monitors.

The Denon and all the speakers are plugged into a Kasa smart surge protector. This way I can just tell my Alexa to power on and off all the monitors as needed.

I’ve noticed that even when the Denon is off, it’s drawing a few watts. It’s not a ton, but over the course of a month it adds up to 2 kW h.

So I’m wondering if there’s any issue with powering down the Denon and then cutting power off at the strip. Is that harmful to the unit in any way? How long will the unit save my settings when completely cut off from power? Are there any other issues / reasons not to fully power down in this way?

Thanks in advance!

You'd have to tirn the maibs supply off in order to prevent it using anything at all while in standby. You can also dissable some of the features such as HDMI passthrough in standby or the network in standby features in order to reduce the wattage it uses while in standby.

Basically, any device will continue to consume some electricity while it is in standby as opposed to being turned off at the mains.

Turn off the mains supply and the AV receiver uses zero watts, but you obviously lose the convenience associated with having it on standby.

That's a helpful chart, I'll play around with those settings.

But going back to the original question - since the AV is connected to a smart plug it's incredibly convenient to cut power to it. Provided I put the unit in standby first and then cut power to it, is that damaging to the unit in any way?

I've done this using remote control power strips to all my AV gear for well over a decade. No problems so far. The only thing to ensure is that the device(s) are in standby rather than powered on.

Just make sure the Smart plug itself doesn't use more power than the AVR would in standby. I suspect it might.

Awesome, thanks. Exactly what I was looking for!

Probably true, but the smart strip also powers all the speakers, so it’s not going anywhere.

If you turn off the HDMI passthrough, the network standby and the CEC, then (measured) it sits at 0.1w.

That 2.4Wh per day, multiplied by 365.25 (the average year) is 0.877kWh per year.

I don't think it will necessarily damage the unit but I would guess that the PSU is optimised by design to be on standby - that's how most people use it for less than 30p a year.

And that's assuming it's on standby 24/7 every day e.g. if it's used for 6 hours a day on average you can reduce that standby consumption by 25%.

Quick silly question, I assume if all your speakers are active that you have ECO mode on when in use? That saves significant amounts of energy.

At ~6 hours powered on a day, that's roughly .24kWh per day saving. About £2 a month.

Of course, I don't know what the idle consumption is of the speakers' active systems versus the x3600's idle with ECO OFF but you have already chosen the speakers :)

Thanks for all the smart ideas re: settings. I also contacted Denon support, who suggested similar things but also confirmed:

Just in case anyone cruises through here in the future and is curious.
