Receiver Power Outlets for Amplifier? - Blu-ray Forum

BACsader · 03-09-2009, 07:02 PM

Hey there,

So today I got my Acurus A100x3 amp and needless to say I am pretty happy with it. It sounds great and really makes a huge difference. My question is that I can see myself getting annoyed that everytime I want to watch something or turn it off I will have to walk up to the unit and turn it on and off using the switch. Do you think it is too much power to draw from my receiver and just use the receivers power outlet for it? Thanks for your help.

kpkelley · 03-09-2009, 07:06 PM

most receivers and pre/pros have outlets limited to about 100w. Your amplifier probably needs more power than that. I would even suggest not plugging it into anything other than a wall outlet, there should be ample shielding and power protection built-in.

Is there no voltage trigger or anything of the sort?

Opips2 · 03-09-2009, 07:21 PM

please. check your manual book on the AV/Receiver. if over much watts can failure or damage your AV/Receiver.

My receiver 50w outlets.

use best equipments

-CD-player
-DvD-PLAYER
-BD-player
-Tunetable

Don't do not with
-PS3
-Amplifiers
- heavy eqiupment

Ok wow. I figured as much. Thanks for your help.

You can get a remote controlled power strip. I was looking at one at newegg a bit ago. Also, it is my understanding that the PSW10 sub powers down after 15 minutes of not being used and then will power up when you turn on your AVR. I don't know if the PSW11 does this (is it PSW110?)

BACsader · 03-09-2009, 10:09 PM

Yeah, the PSW111 has a power toggle but I have that hooked up through the receiver right now and it seems to be doing fine with it. Do you think maybe I should hook the sub up to the wall.

Opips2 · 03-09-2009, 10:20 PM

oh i forget about Subwoofer!!

Don't do not on AV/Receiver. use best a Power Condititor. you'll fine!

You should never use a receivers power outlets for any type of external amplifier, they are not rated for that. In fact in my 20+ years in the industry, I don't think I have ever used them for any purpose. Source components can pick up noise, and should be connected to a quality line conditioner. Amplifiers should have enough internal protection/shielding to be plugged direct to wall outlet, which should be on a dedicated 20 amp grounded circuit. Best of luck.

Big Daddy · 03-09-2009, 11:53 PM

Some amplifiers have built-in power conditioners. Some don't. As a general rule, amplifiers draw a lot of current and their power requirements are high. Some amplifiers can be plugged into high quality power conditioners. Others should be plugged directly to the wall.

The manual of my 6 channel Cinepro amplifier warns about this and recommends that for best performance, the amplifier should be plugged into the wall outlet.

It is good excercise. Get up and turn it on and off manually. In addition to my receiver, I have to manually turn on/off 7 amplifiers in my HT room and I don't mind.

sokrman14 · 03-10-2009, 12:08 AM

My receiver and amp use a voltage trigger. I ran a "mini jack" from the back of the receiver voltage trigger output to the amp's voltage trigger input. It plugs in as normal to the wall or powercenter, but everytime the receiver turns on, the amp turns on, turns off accordingly as well. See if you can do that.

I don't mind turning my amps on/off either !
If you have A spare room Big Daddy , I'll turn the amps on & off for you !!

Congrats on the Acurus amp.

How much did you pay?

Why did you pick this 3 channel amp over others?

Just want to know because I'm interested in getting new fronts and center and new amp to drive them.

BACsader · 03-10-2009, 12:39 PM

For this Acurus, I payed $392 with shipping. It is expensive for a used unit but it is in excellent condition. I picked a 3 channel amp because I really don't think my rears would benefit all that much from being amped. I had never heard of Acurus before but I saw it on Audiogon and it was in my price range. I typed it into google and all the reviews for it gave it a lot of praise. The unit itself is pretty good looking and I read that it ran very cool, which it does.

It's too much power - don't do that

The amp needs to be on its own outlet.

I have to manually turn on 5 power amps when I power my system up...everytime. No problem - I look at it as just a little more exercise

That's not expensive for a used Acurus

good deal

Too bad your speaker manufacturer killed the brand along with Aragon

I added 3 dedicated outlets one for my TGA7400 amp and one each for my Sunfire subwoofers. My wife even agreed to this because she noticed a lamp in the living room that woud dim at low volume, and become a strobe light at high volume when any bass was present on the soundtrack. It was the only other thing on the circuit with the rear sub

In the end adding the dedicated outlets did help improve sound quality and dynamic range improved

Also have "NO" "Zero" noise or hiss

BACsader · 03-10-2009, 04:17 PM

Right now I have it hooked into the wall. The only thing I notice is a pretty distinctive hiss, but, it is coming from the receiver because when I remove the RCA into the line inputs on the amp the hiss goes away. Do you think maybe weak shielding on the cable or "dirty" power going to the receiver and putting noise in the line?
