Is the fan usually on? Would it be noisy in a hometheater (sub amp) application? Amp will be placed under tv.

I purchased this for my church sound system and it works great. It is not noisy at all.

To be honest it's not really quiet but not annoyingly loud either. I have 3 of them in a rack mount in my 12 x 15 ft. living space and don't really notice them unless it's really quiet. Hope that helps! You'll love the power. The 4000 isn't much more cost wise if need a little xtra zing! I have 4 - 12" into 4 ohm drivers and that's what i use.

I call it quiet, even under load. I still hear fans, but they don't overwhelm my tiny speaker system. If you want zero noise, then this won't work.

Mystic-Buddha...This fan is whisper quiet and if it is noise you want, then get the portable double directional fans. One set of fan blades blows inward and the other blows outward they tend to be noisy.It's either that or turn the stereo/TV volume higher.The Lasko Oscillating fan is surprisingly quiet.Good Luck.

Just set mine up. I do have a home theater system, so it isn't an issue with me. But I am also not impressed with the sound from the tv. You certainly should be able to hear it over other noise, even though it could be louder.

I have one of my 5 fans on my receiver, so it is laying flat. So far, I have not hear any noise or vibration of any kind. Only time will tell.

While you do hear the unit, it isn't loud at all and shouldn't interfere with tv. It's a bit like a small fan - not half the sound of an oven vent or a large electric fan.

When the TV is turned off there is no fan noise coming from the TV. To my ears, it is completely silent. I have never heard the buzzing sound that some people refer to. Hope this helps.

Are you sure it isn't the subwoofer? It stays on all the time even when the system is turned off and produces a low level hum, constantly. That seems to be the norm for all the subs and the Onkyo receivers. I was surprised to walk into my media room and hear the hum coming from the sub and the system was turned off. Sub is always in stand by. Just a thought.

Probably, I find it noisy in the effects loop of my amp. Not so much directly into input.

Work fine! I believe it has a small fan. I have it running half of my whole house audio.

The sound is normal. The unit has higher power use and needs a fan to cool the unit.

My need for the fan is for an audio amplifier that during warmer days would automatically shut down after 20 to 30 minutes. I'd wait 20 minutes and i was able to turn the amp back on. Since it was an over heating problem I installed the fan. I connected the fan's power cable to the amplifier so when I turn on the amp the fan goes on, amp off fan off. This works for me, maybe might work for you instead of running 24/7.

I put the fan in the middle directly above the amplifier it cools. The area above the fan is clear of obstructions ensuring that the fan works efficiently.

You don't need to have the fan on if you are using it for the home theater. I believe it was designed for several network equipment running simultaneously. It doesn't bother me the noise, but I don't feel the need. The rack is excellent quality for what I paid. They raised the price by a couple hundred dollars right after I placed my order.

If you use the sleep mode it is a low hum but I usually can't tell it's on. On regular mode just sounds like a fan.

It's noisy, I have mine in my movie room and do not really hear it if the TV is on. But if ur going to put it in ur bedroom it will prob keep u up at night.

the amp is at 4 ohm load, 2ndly are you asking about the implications of series or parallel hookup, hook it up to stay at the 4 ohms,= series. read a bit on the net about series & parallel. try them one at a time, noting amp temp,! aka does the fan come on? mine never did, so if yours does your pulling serious juice & sensitivity how much pre-amp line voltage required. are these subs or full range & are they in stock cabinets?
