LC-1 Remote Amplifier Level Controller,Black,Small

This device some people call a bass knob which is okay because I do too. It's actually a line level controller which works similar to a base knob except you can add this to any aftermarket amplifier utilizing your RCAs coming from the back of your head unit. This controller has the line level input from the back of your stereo you plug that into the input then it has RCA left and right output you plug an RCA cable to the output side and the other side of those cables you plug into your amplifier. All it does is decreases or increases the frequency of output going to your amplifier kind of like a middleman that way if you have songs that have really strong bass You can turn the controller or knob down and vice versa similar to a bass knob except like I said earlier you can use it on any amplifier. I have an amplifier that has an actual bass knob and it started crackling because the knob was going bad after 3 years so I decided to purchase this with great reviews and great videos. I found this to be the best choice. I'll make a long story short. When I turn off my truck it is completely quiet as far as my sound system but when I turn it on or crank it up after a few seconds my head unit comes on and there is a strange thump in my subwoofer. When I had the bass knob hooked up even with the level all the way down it's still thumped. When using this line output controller/bass knob I turn it all the way down when I leave my truck and when I crank it back up I wait for the head unit to power up and then I have no thump whatsoever from my sub so this thing can actually cut the signal down completely instead of partially so there is very good control utilizing this knob controller. I would definitely recommend to anyone with any kind of aftermarket amplifier controlling a subwoofer to use one of these. They are relatively inexpensive and a good piece of equipment to have in your sound system.

I have used these PAC level controllers for many years now. In most cases I actually prefer using them on a subwoofer amplifier over the level controllers that come with some amplifiers and plug directly into the amp for a couple of reasons. The first reason being is that these PAC controllers are in cased in a plastic that can easily be removed with out damaging the circuitry. This allows you to just use the working circuitry inside of the casing which is a potentiometer and small chip. This makes mounting the controller much easier and nicer, because you can then simply mount the much smaller potentiometer into a small hole on the dash or other compartment in the vehicle hiding the potentiometer behind the dash where only the knob itself is seen. (Picture is controller mounted in my Tacoma) "Sorry I did not take a picture of the controller after removing the case". With the bulky case around it you are stuck with mounting the level controller via two small screws on the outside of the dash, which is an ugly eyesore. Some might think, "well wouldn't the level controllers that plug directly into the amp be a better option" than this PAC controller. Well the answer is in most cases is no. I will explain why. This PAC LC-1 controller connects inline to the RCA coming from the head unit to the amplifier. So it is directly controlling the signal going to the amp. Since it is controlling the signal going to the amp it is capable of completely turning the amp signal all the way down so that no signal reaches the amp. Thus there will be no output to the woofers, which means no sound coming from the woofer. This is great because there are times you want to have your music with out all of the bass. Now the level controllers that plug directly into the amp controls the output gain on the amp, so it can only turn the gain down as far as the amp will allow. In many cases with amps, even when the gain on the amp is turned all the way down it is still sending voltage to the subwoofers which will produce sound. The sound from the woofer will be much lower, but it will still be audible. Simply put if you want to be able to control the volume of your subwoofer from full mute to full gain. This PAC LC-1 controller is the way to go. They are quality made, easy to use, and work very well. One other thing is that since they control the signal going into the amp instead of the gain going out of the amp. They can be used on any size amplifer, because signal input from head units is usually no more that 5 volts. Which is easily handled by this controller.

Works tremendously better than I expected. A piece every system should have. And you can't beat the price

This is a line level control device. I use it as a remote volume control for a Pyle amp that is out of reach in my 2.0 setup. I just received it but here are a few of my initial thoughts. DESIGN It's a little hard to tell from the pics the exact design of this item so I thought I would offer a fuller description here. Basically, it is a 1" x .5" box with a volume knob on the front that protrudes about .75" and then it has two 6" pigtails that come out the back-one for in and one for out. Each pigtail has female, stereo RCA jacks on it. Although not excessively well built this device does seem sturdy and it should hold up to some abuse for a time. Not sure how long it will last as much of it is plastic. OPERATION In order to make use of this line level controller one would plug male stereo RCA cables into its input and then connect its output to a receiver or amp. The controller then can adjust the volume going from the audio device into the amp. It is straightforward and simple to setup and took me no time at all to configure. This, however, is where my two caveats come in. First, the volume knob produces some dirty noises, especially towards the low end. There is audible static when you reach lower volumes and at one point the left channel goes out and then comes back in as you keep turning it down. This is not till the last eight of a turn of the knob, but still a little annoying. Also, this controller does not completely cut the volume when turned completely down. I was still able to hear audio come from my stereo even at its lowest setting. I was hoping to be able to completely shut off the audio with this device. Perhaps if you input device as turned way down. Say, for example, if you were using an iPod as your source and turns its volume 3/4 of the way down. Then you may be able to completely mute the volume with this controller, but you top end wouldn't be as loud. For these two reasons I have given this device four stars. It does what it says it will, but with a couple minor caveats.

Nice little bass knob, which worked perfectly with my pioneer head unit, and recently installed mono amp and subwoofer. Highly recommended!

I ordered this product recently, to use in addition to my existing car audio system. It arrived promptly, and in good condition. The reason I ordered this item, was because the existing audio system in my truck, was wired and equipped with upgraded sound with includes: 2- amplifiers (1- Rockford Fosgate 150RMS x2ch amp, and 1- Kenwood 900RMS x1ch) which powered three speakers (2- Infinity 6 x 8 Front speakers, and 1- 15" Orion XTR2 Pro Subwoofer), but I had no control over the volume of the aforementioned installed amplifiers. After some research, I discovered that certain types of amplifiers (JL Audio, some Rockford-Fosgate amps, Boss, Memphis, Hi-Fonics, to name a few) come already equipped with a "Volume", or "Bass Control" knob (which connects directly to the amps) but mine did not. So I tore into my system and put this lil bad boy (PAC LC1 Remote Amplifier Level Controller) in between the Line-out converter, and the Amplifiers. It works perfectly, and provides me with the overall control of the volume of the amplified speakers (subwoofer included.) I give this Item 5 stars because of it works exactly as described, because of its ease of installation, and because of the price. It really is an amazing value!!! I definitely enjoy having such control at the tips of my fingers, as I am quickly able to turn down the volume of my upgraded sound system. It has the ability to completely mute the amplified sound. Which I like to do when traveling through residential areas, purely out of respect. I would recommend this item to literally EVERYBODY! Especially audiophiles, and other people who are really into building, or creating noticeable improvements to their car audio systems. This item isn’t limited to only car audio, as it will also work with home surround sound systems. I thank you for the time you have taken to read this review. If I left out any important info, or you have any questions, please feel free to leave a question, and I will gladly respond. -LGV

Got this to turn down my amp' accordingly/ since touchscreen 2din mp3 unit doesn't have amp/sup aux rear out control, this is great alternative. Mounts with 2x tiny screws, kind of crappy and PiTa' Too get started.. but they work when pre-drilled. rite size screwdriver... Or use you own small screws.. pre-drill, small self tappers.. you'll need a short 1.5-3ft RCA cable too connect this too your head unit from under dash.. The cables attached are long, almost reach but, not long enuff for a truck or tall dash. Id grab a small 2-4ft extension of RCA male-male cables just in case.. depending were you mount it. As for the controller. its great. handle 2k watt amp no problems.. Solid build quality.. The fade from 0-100% seems too work great. Nice smooth dial. It goes all way down too 0% or off. I listen too all music, so its nice too be able too reach down and turn my sub' up or down a tad- Or off if I need.. Only things could be better, maybe the screws, bit longer atleast on input of RCA too reach head unit on big vehicles.. and last, a tiny bit of glow in dark on dial, or led would be awesome too help find it at nite.. But I can live with it as is, especially for price an how it works..

Love the lc1 bass knob my dad used it back in the day for bass competitions and now im using one and all I can say is this thing is pretty smooth.

音楽のジャンルによっては異常に低音がうるさくて・・・。 そんな時に役に立ちます。

Well made does the job

Excelente producto, robusto se siente de buen material y construcción, hace exactamente lo que se espera, espero dure muchos años, muy recomendable

Does the job and I have no complaints that worked out very well I love it

生産終了しててどこ探してもリモートコントローラーがなかったので困ってました ここで興味深いのを発見！ 二つも買ってしまった。 いやぁ 助かりました。 音質にも変化ないし、音量0もできます！ リモートコントローラーって0にできるやつ無いですよね…(あったらごめんなさい) それにノイズもありませんでした！ デメリットは 配線がかさばることだけです！
