Should this knob be placed before or after amplification from the source? I get a lof of noise if i plug in before amplifier.

After ....... And I recommend Checking out Autotek 7007 this will change your music quality , but I still have my PAC knob but it's unplugged ! The Autotek has knobs SubSub bassMid bass Mid Treble and the blue light is very cool looking and had a built in crossover but if your using the Pac knob u will need two Couplers one for the head unit and one to the amp ..... U can email me if u like blessedwithfaith78 at gmail

If you are using a guitar cord from the output to the amp, you will get noise. What I do is use speaker wire which has no winding ground wrapped around the main (lead) wire. This prevents the cord from picking up outside interfernce.

Honestly I'd go with the Rolls solid state pre-amp filter and not the passive like I have - I'm going to have to call Rolls and to see what's the best device to boost the input signal into the passive filter - I'm getting excellent sound but I want more volume when using the G5 - for most people it would be more than loud enough - it's really a simple fix of having a good pre-amp - I see what your doing - all I can say is I'm not having your problem with my set up - you need to make sure your signal is clean

Greetings: I am using this inline with my ignition wire to cut out engine noise to the amplifier. It worked a little and only after I turned the gain down on my amp did all the noise go away. That's all I know about the operation of this product.

The pre-amp is self contained in the unit. It's output is fine to plug into an aux input of your receiver.

I grounded my turntable to the pre amp. Look. At the back of the pre amp for a ground bolt

The low humming noise is normally caused by not having a "ground" wire connected from your turntable and the pre-amp/amplifier. There must be a "grounding" connection between these units to alleviate background noises. Make sure there is this "grounding" connection. If there is a ground connection then it means that there is a break in the wire between your turntable and the amplifying unit. If there isn't a grounding wire, then you must provide one to have a "grounding" effect between your turntable and the amplifying unit. Hope this helps.

Yeah its normal, it'll start to cut off if it overheats.. what i did was attached two 1x3, one on each side of the amp, just to raise it up a little for air flow. (Essentially you can raise it a little more, probably like 2 inches)

You have a left and a right channel. Each knob controls it's respective sides output. There is a blue power led to tell you the unit has power. A yellow protection led for low voltage or over heat events. And a red clipping led above each knob to indicate a signal clipping issue when over cranking the amp. Clipping can cause severe damage to your speakers if left unchecked. To hook up a microphone, it would be a good idea to utilize a stereo mixer. If you read this and have no idea what I am talking about, then go to best buy and get something with instructions and flashy light panels because you won't get how this thing works.

Yes. While I was turning the knob it went down. So I pulled it back up and I'm careful not to push down on it anymore. I also rolled the tubes to WE396A. The sound I have now is unbelievable. That's no joke. I thought it was all hipe, but I was wrong.

About the noise when the volume is turned up high, keep in mind that it's usually static creating that noise. If your speakers and amp unit is too close to your tv, computer or anything of that nature, it's bound to create noise at high volume levels. Some can actually create noise even in low volume levels. Always test the area first.

I had no problems. You are turning on the toggle switch on the back of the amp, correct?

Does the amp work and power your subs? Trace your wires and make sure everything is in the right place. Do not turn the knob to full on yet cause it can't break easy, put it halfway or under half. And turn your car over and see if it works? If not send me another question and ill look at mine specifically

MAKE SURE YOU HAVE THE VOLUME BUTTON THAT'S ON THE TOP RIGHT-SIDE IS TURNED ON....It's a volume knob!!!!! About an inch and a quarter in diameter. THere's a slight indent on it....turn music on...and then rotate dial both ways until it starts booming. I hope that is your problem. I think it got me when I bought these used...I didn't know about it until I ordered a new amp panel from Definitive Technologies....$95. But when I went to replace the amp panel...that's when I realized this circle WAS A VOLUME KNOB! UGGGGG!

Same response as the others -I would recommend against that. Unless the switches are "break before make" - meaning the switches break their connection to one output before making contact with the other output - you will be shorting together two amplifiers. IF (underlined) you only switch from one amplifier to the other WHEN (underlined) both amps are turned off, you might be OK. A bit risky, though. All it takes is one time to forget while one or both amps are turned on. There are AB switches specifically designed to do what you want to. I would suggest buying one of those. I know that Niles makes one. Same response as the others -I would recommend against that.

There is a level adjust knob on the back of the unit, have you turned the knob up as to not be on "0"? Confirmed the LFE input is properly seated and also that the subwoofer power supply is plugged into your wall outlet?

If your not changing the amp stick with the same ohm. Otherwise it might sound like crap or worse and blow something.
