Russound ADP-1.2 Speaker-level to Line-level Adapter

This little device saved the day after I bought a new Klipsch subwoofer that did not have speaker level inputs to connect to my vintage tube amp. I didn't know these existed outside of the car stereo world until CJ found it for me in live chat! Exactly what I needed, easy to connect and sounds great!

Pros: Small, easy to connect, effective in converting speaker level signal to line level signal, when your amp doesn't have a sub-out and your subwoofer doesn't have speaker level inputs.

Cons: No cons!

Works well but needs a case.

Pros: Easy setup,

Cons: No case.

This does exactly what it's supposed to do, and does it well. When the receiver lacks pre-outs, this is the only real solution. My only minor complaint, like others, is it lacks any enclosure as an option.

Pros: Great solution to a vexing problem.

Cons: Would like to have an optional enclosure.

Perfect for my need! I needed a way to hook up a subwoofer to a tube amp with no preouts. This little item did the trick.

Pros: Easy to use Purpose built Fairly inexpensive

Cons: Would have liked it to come in some type of project box

This circuit board worked great. It allowed me to connect my receiver to my Sonos system using the RCA jacks.

Pros:

Cons:

Nothing complicated about this product, it does what is supposed to do. Very pleased with the ordering process and receiving the delivery on time.

Pros:

Cons:

Works great! Just what I needed. Thanks for all your help and expertise.

Pros:

Cons:

The unit is without a costly housing, and cab be located anywhere....great!!!

Pros: Simple way to get from speaker output to signal input...it works!!!

Cons: None

My HK receiver does not have preamp outs. I wanted more power to drive the L and R speakers when listening to music. The adapter is working great driving a Crown 1002 amp. It is clean and quiet.

Pros: Works great

Cons: None

It may not look nice but it works! I am using it to send a signal from my integrated tube amp too my subwoofer. Fast shipping and great build quality. I also installed the unit in a home made enclosure to protect the unit.

Pros: Build quality and components.

Cons: Lack of an enclosure to protect the electronics, but is no big deal.

Exactly what i needed to support my Denon AVR + Parasound amp. Super easy install, no discernible noise or unwanted side effects - amp sounds amazing! Like that it is open (no case) and comes with a mounting bracket, perfect install on my DIY TV stand. Crutchfield got it to me in just a few days and i don't think it could have possibly been packed any better! Highly recommended if you have the need for such a device. Thanks Crutchfield for an overall excellent experience & very effective product.

Pros:

Cons:

This product works. My subwoofer only has line in input and my receiver only has speaker out; this is the only way I found to get the subwoofer to work, and it sounds really good to my ears. My only complaint with this product is that it does not have a covering; the electrical components are completely exposed to dust etc, which makes it very awkward to mount. In the end, I used the foam sheeting it was packaged in and created a cocoon around the product; then I taped this to the top of the receiver. Not very elegant but it works. For not having a proper casing, the price could have been lower, but I couldn't find any other products on the market that do what this does. Overall I am happy with the purchase.

Pros: works great

Cons: -no enclosure; -bit pricey for exposed electrical components

With my ONKYO HTR-494 Dolby Atmos receiver I connected Harman Kardon Speakers. The Center speaker lacked clarity. I replaced my harman center speaker with BOSE GS Series II Cinemate speakers with the help of Russound ADP-1.2. Solved my problem as there is no pre-out in Onkyo 494. If you have no pre out on AVR this is the solution. Awesome Russound. I am planning to buy 2 more.

Pros:

Cons:

Great Product, not pretty but it works very well.

Pros:

Cons: None

turn ok but then my denon avr would protec mode

Pros:

Cons:

I'm not an electronic tech guy. Was looking for a long time for this solution and finally got it. Installed between my Onkyo Entertainment 7.2 and M-Audio BX8 for using as the front L & R. Guess what! It rocks. Pounding my ears and chest. Chip solution for upgrading from regular speakers to a Studio Monitors. Gosh... Never before could heir sounds and noises coming from movies didn't know are included. Now just need more to upgrade all surround speakers for monitors and I will be a part of the games and movies. The cool tiny thing makes wonders.

Pros: Works awesome.

Cons: Two days long to figure it out that I need to flip up all the way above the conductors all four black plastics like a switch. That's the way should insert the speaker wires firmly. (No estar bueno)! ?? Dummies like me we're need more instruction details, please.

Worked great for conversion of my speaker level amp output to line level in for my home audio powered sub.

Pros: Ease of use

Cons: None

Speaker side connector difficult to open for wire insert as is disconnect feature Othetwise, audio signal processing does its job I would recommend

Pros:

Cons:

Had to connect speaker output of amp to line input. This device works great and easily.

Pros:

Cons:

The product is just awesome and received on time.

Pros:

Cons:

I am using this because my onkyo receiver does not have pre-amp outs, but I want to power my new Polk RTi A7 speakers with a stand alone power amp (Crown XLS 1502). Works great, was easy to connect and the sound is clean! I can't tell that there is any added noise in the signal due to adding this device. I am happy with the purchase and would highly recommend if you want to run an external amplifier, but your receiver doesn't have pre amp outputs.

Pros: Small and affordable

Cons: None

Great product for using powered speakers with a receiver.

Pros:

Cons:

Exactly what I needed to add an amp to power my outdoor speakers on my Sony receiver. I would of had to disable a pair of speakers to use the preamp output on zone 2 but by installing this everything is working together

Pros: Easy to install

Cons: Should be enclosed

Worked exactly as expected. It could use a simple cover to make it more attractive.

Pros:

Cons:

When my house was built I pre-wired for speakers in the living room, but did not consider speakers in the back porch. I installed speakers in the back porch last year and tried a couple wireless options to get sound outside with poor results. I also tried to pull wire all the way back to my receiver, but because of concrete construction was only able to get to the living room's speaker posts on the wall. This unit was a simple, straight forward way to connect to those speaker posts and get a line level signal. Once I had this I hooked up a simple small T-Amp and now I can drive the speakers in the back porch. This solution is working much better than either of the wireless solutions I tried; no extra load on the receiver, no delay between the rooms, sufficient power from the T-Amp and the ability to turn off the T-Amp when no one is outside. If you have a need for something like this, highly recommended.

Pros: Does exactly what it says

Cons: I wish it were enclosed. A little pricey compared to other options, but those are for car audio purposes and this one is from a home audio manufacturer, so it just works.

I purchased this for a solution to send my Center Channel on my Denon AVR wirelessly via Bluetooth to my soundbar in my home theatre that doesn't accept speaker level inputs. I purchased a small enclosure for it for protection since its usually a vehicle under-dash install.

Pros: performs exactly the needed unique solution for signal transformation.

Cons: An option to buy it with an enclosure would make it perfect

Was looking to solve multiroom, multi-amp challenge. Had tried feeding secondary amp with RCA backconverting high grade inwall speaker wire. Got signal but way too much noise. Initially tried car line to rca converters but no signal at all, prob impedance issue. Ordered Russound product and appeared to cause the dreaded hum from primary amp even if powering channel to Russound was off. Called Crutchfield tech support they went above and beyond to help troubleshoot prob (several calls). Long story short we solved a polarity issue in wall jacks followed by a ground loop issue (used PAC rca filter). Difficult challenge, all issues solved with the help of Tech support. Nice work

Pros: Can be used to feed secondary amp in home audio system where few options were available

Cons: Not much in terms of install trouble shooting. Be sure to be aware of polarity and ground loop

The device does exactly what it is supposed to. Brought my speaker output on my vintage pioneer receiver down to line level for input into a powered subwoofer. I only question the design. The circuit board and all components are exposed if left the way it is. Would be sturdier if encased in some sort of housing. Could "DIY" it but for the price, would be nice if it came that way out of the box.

Pros:

Cons:

Simple, inexpensive, works as stated. If it's what you need, it will work.

Pros:

Cons:

Works as advertised. I used three of these to provide signal to three power amps on my living room surround system (Receiver did not have audio preamp out). Would have given 5 stars if there were a cover for the unit, but I suppose they're intended to be mounted to an amp board in a vehicle. Work well.

Pros: Small and inconspicuous.

Cons: No cover... board will collect dust.

I purchased this device to run a pair of subwoofers from my Line Magnetic LM-518IA (integrated amplifier). The 518IA does not have any pre-outs to connect to a subwoofers and my subwoofers do not have speaker level inputs. I was able to use this device to convert the 518IA speakers outputs to line level inputs for the subwoofers without any noticeable issues. It works perfectly for my needs. Your mileage may vary.

Pros:

Cons:

I bought this product after discovering that the Russound Amp that I purchased could not be joined with another amp unless I converted speaker level to line level. After adding this product, everything works fine. I'm not sure why this product is so bare, but it works....

Pros: Works

Cons: I little pricey and bare

This little gadget saved the day.

Pros: Does everything it's supposed to

Cons: If it had a case it'd be better.

This device takes amplifier speaker output levels and converts them to line levels for input to another amplifier, or any device requiring low level input. It works perfectly for me. I use it to provide surround sound signals to my Recoton transmitter which are picked by by a recieiver connected to self-powered rear speakers. The alternative would have been to crawl under the house to route speaker lines to the rear speakers. My wife said laying them across the floor was not an option.

Cons:
