Onkyo TX-SR806 Power Usage

math wizard

I'm using my Onkyo TX-SR806 as a pre/pro only. Does anyone have any idea how much power this units uses when used as a pre/pro only? I'm also not doing any video processing. Just using the HDMI as a pass-through to the TV.

You could pick up a Kill-A-Watt and find out. That would be the easiest way to know exactly. I would not guess that it would use much power when in that configuration. What do you want to know?

I don't want to overload the circuit I'm using for my set-up since I've just added two amplifiers.

I would recommend installing dedicated circuits then.

I would just hook it up and try it. If the breaker trips, then see post #4. Otherwise good to go.

Well, better be on the safe side...

Doesn't Onkyo give any figures for running idle..which I imagine would be the level of power you're consuming?

As a pre pro, I would guess around 1-2 amps.

"Electrical Consumption

We also look at an AVRs idle power consumption since electricity use, especially as it relates to something "just sitting there" is of increasing importance to people. Not surprisingly the numbers are slightly lower than last year's model: the power-on consumption with no audio signal hovers right around 88 Watts in the default >6ohm speaker setting. In the standby state its consumption is below what our equipment can measure so it can be assumed to be less than 2 Watts which is excellent! As we expect, when switched to the >4ohm speaker setting idle consumption drops to just 56 Watts. At first it may seem point moot since that setting is all but useless, however if using the 806 as a preamp/processor coupled to an outboard power amp, placing it in the >4ohm setting might shave a couple kWh off your power bill at the end of the year (or make you feel just a little less guilty if you leave it on by accident when not in use), and the unit gives off marginally less heat.

Please note and be aware though that if HDMI-Control is enabled, the 806 consumes no less than 50 Watts when in standby....all day, everyday. The feature allows the 806 to "control" compatible equipment (say, turn on a TV for example), but would you really leave an incandescent lamp on 24/7 just for the convenience of not having to reach for its switch?"

I have an onkyo 805 hooked up to my power center and when I turn it on my amp reading goes from 1.1 to 1.5 so I would guess .4 amps or 48 watts.
