Turning On / Off At Mains

[kinda]

Hello,

Wondered if anyone had advice on the safety of this?

I've got several pieces of equipment, all connected to the mains via surge protection sockets.

It would be easier to turn everything on and off with the mains switch, but I've worried it could damage components. Though ostensibly it should be the same as using their buttons, I wondered if AV receivers, subs, and so on, might have shut-down or start-up routines that don't happen the same if they just unexpectedly lose juice.

Anyone got any advice or experience?

I have been told that when powering up my system, to always turn the volume all the way down on the amp, and only then power it on ....

and then only to power up the cdp ... when switching off ... always to switch the cdp off first, then the amp

not sure if it has any merit but I do that anyway

my amp manual says the opposite

power source on first then the amp

power amp off first then source

I agree with one off recommendation , switch on the source - amp- sub ,switch off in reverse , this is to prevent pops going through the system to the speakers causing annoyance and possibly damage

OOPS .... will do it the proper way in future

I turn my equipment off using their own on/off switches, then turn off at the mains.

I'm with you ElectroMan - except for my TV - Samsung LE46A956. If I switch it off completely, I lose all the adjustment to settings. My amp (Denon 4310) and BDP (Oppo 83) retain their settings after power off at the mains.

I power off everything with this. No problems. Also confirmed with my dealer that it's safe.

I always power off components then turn off at the mains. No red standby lights equals no enticement for little fingers. I also only plug my x-box in when I'm using it. Don't know if this improves the sound/picture of the CD/BD/DVD player. The amp is plugged into it's own socket not the tacima.

Turning volume knobs down to zero is de rigeur when the signal actually goes through the volume rheostat as it prevents arcing across the contacts and subsequent black spots (no volume at all) on the diaI. It's not so necessary when the volume knob is controlling the volume electronically through a transistor circuit.

I would always turn the amplifier off first, then the source, follow the reverse when turning on, as this prevents the amp picking up the arc from the source on/off switch - if it too actually carries the current rather than simply tripping a transistor bistable.

I only ever turn off at the mains (or more usually pull the plugs completely) if I'm going away for more than a weekend or if there's a thunderstorm (live in Houston for a while and you'll understand that one). This prevents thermal cycling of the power supplies which is the main cause of their demise in most cases.

My "green" conscience, such that it is being in the oil industry and all, is clear. All our electricity up here in the North of Scotland is hydro-electric.

Thanks for the replies.

Sounds like in general people don't do this, although Chris has found no problems.

If doing by the mains switch, I would be turning on the TV, amp, and sub at the same time, but the DVD player and freeview recorder would be turned on separately.

Sounds like it might be OK, except the sub and amp would come on together. I'll probably play it safe and keep turning on off as most of you do!
