Russound ADP-1.2 Speaker-level to Line-level Adapter
Crutchfield Customer Review (What's this?)
Works great! Just what I needed. Thanks for all your help and expertise.
Use this adapter to convert a speaker-level signal to a line-level signal. It's great for sending the amplified output of a multi-room audio system to a more powerful amplifer, or adding a second amp to power more speakers. The adapter features a four-conductor speaker wire input and a female RCA stereo output.
Works great! Just what I needed. Thanks for all your help and expertise.

Works great! Just what I needed. Thanks for all your help and expertise.
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!!!
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
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.
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.
Great Product, not pretty but it works very well.
turn ok but then my denon avr would protec mode
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
Speaker side connector difficult to open for wire insert as is disconnect feature Othetwise, audio signal processing does its job I would recommend
Had to connect speaker output of amp to line input. This device works great and easily.
The product is just awesome and received on time.
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
Great product for using powered speakers with a receiver.
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.
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.
Simple, inexpensive, works as stated. If it's what you need, it will work.
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.
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....
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.
Overview: The ADP-1.2 is an easy way to adapt a stereo speaker-level signal to line-level; this line-level signal can then feed an amplifier or other audio device. It can be used send the amplified output of a multi-room system to a more powerful amplifier, or to add a second amplifier to power more speakers. The input terminals are screwless and accept bare wire up to 14 gauge. The output is female RCA jacks (stereo). The maximum input power is 250 watts RMS per channel.

An inexpensive home-audio solution to interface a stereo-level receiver with a line-level home speaker system. Unlike car audio adapters, this product will handle the power a home stereo receiver will generate. [ Alan Nov 13, 2017 ]
I just got one of these to connect my old organ speaker output direct to the PA... IT WORKED! [ WAYNE Oct 25, 2017 ]
Your description was clear and complete Opinions presented by users provided a vote of confidence [ Carl Oct 20, 2017 ]
Older Integrated Amp-only speaker output, needed line level for active subwoofer. [ Gerry Oct 18, 2017 ]
It was going to connect directly to Russound equipment. [ Daniel R. Apr 29, 2017 ]

I need to hook up my ancient amp which has no dedicated subwoofer out to a modern subwoofer which only take RCA input. [ ming Dec 23, 2016 ]
Connecting an older receiver to a wireless transmitter system requires this adapter so the volume can be controlled through the receiver. [ Mark Dec 10, 2016 ]
Need to conver audio signal from speaker to line out. [ Rudy Oct 28, 2016 ]
I want to use a powered subwoofer with a vintage Kenwood receiver and not use speaker wires. Crutchfield has the adapter for this application. [ CHARLES Oct 11, 2016 ]
With the help from Crutchfield chat, Larry pointed in the right direction....thank you and thank Larry. [ John Sep 23, 2016 ]
The Crutchfield advisor I worked with suggested that this item would work a lot better than the car audio line-level adapter I'd been using (D'oh!). He was right! Works perfectly. [ Bryan Aug 30, 2016 ]
Living room speakers were pre-wired, but I needed to jump off from there to ceiling speakers in the back porch. I'll use these to tap off the living room speaker terminals and run line level to the ceiling speakers amp. [ Richard May 31, 2016 ]
Needed to pad down the front 3 speaker levels to line level outputs for use with 3 powered speakers (front array) used in a home theater system. [ THOMAS Dec 26, 2015 ]
If I understand correctly you are looking to change a line output to a headphone output. This is not the product you are looking for. This device changes speaker outputs into line outputs. The Cruchfield advisors should be able to assist you with finding the correct product you are looking for. [ Carl Mar 13, 2018 ]
That's a rather unusual use case but sure; with a male RCA to female minijack (3.5mm) adapter you can connect a pair of headphones. Ideally, the receiver/amplifier would have it's own headphone output so you wouldn't have to use a line adapter. [ Ryan Oct 18, 2017 ] Staff
There are two rca outputs [ JASON Aug 08, 2017 ]
If the B channel speakers are controlled by the source AV receiver volume control, which you can check directly by plugging in some speakers,then this will work. I'm almost certain that it will work, but it is worth testing. [ Christopher Apr 02, 2017 ]
Yep that is how it works. I am going out from my receiver's surround L and R to an Evolved Sonic Transmitter/Receiver and when I kick up the volume on the receiver the volume on the surrounds increases as it should. [ Chuck818 Apr 01, 2017 ]
yes [ Craig Apr 01, 2017 ]
This unit works just fine outputting a standard line level signal. The gain on the external amp would depend on the source. Since the adapter is putting out the standard line level signal, for the consumer electronics industry, that is 0.316Volts (-10dBv) In the professional audio world that would be 1.23Volts or +4dbu. [ Alan Copeland Jan 12, 2017 ]
I sound fine. in my experience I had a lot interference noise. I connected my receiver to a vintage amplifier to play my turntable. So I think it depends what you need it for. I ended up buying a AV receiver with preout and phono input. [ Carlos Jan 12, 2017 ]
Yes you can, and once you set an appropriate level on the powered speaker, the volume controls on the receiver will also affect the centre channel. [ Richard Dec 31, 2016 ]
The Russound ADP-1.2 is intended to convert an amplifier's speaker level outputs to industry standard "line/pre-amp level". If the output you describe as "center channel speaker line out" is indeed an industry standard "line level output", then no, the ADP-1.2 will not work for that purpose. If, on the other hand, you are actually describing an amplified center channel speaker level output, the ADP-1.2 will get your job done. [ STEVE Dec 30, 2016 ]
This takes regular speaker outputs and makes it a pre amp out put so you can run it to an active speaker. [ JASON Dec 30, 2016 ]
If I understand your question, yes. I don't have preamp out terminals on my integrated amp, so I run speaker wire from my front channel speaker connectors to this. Then use RCA cables to run from this to my power amp. Works great! [ AARON Dec 17, 2016 ]
NO, it will take speaker level output and turn it into line level for mixing or cd/tape deck input. [ ANTHONY Dec 17, 2016 ]
You will connect two chanels that would typically go to speakers directly. The other side of this board is a reduced RCA signal that you will connect to your external amp. Be careful as this board has a max wattage that can be applied to it from the integrated amp. This amp will also control the volume to the second. [ Dustin Dec 17, 2016 ]
I couldnt get it to work on any of my Marantz amps, tried to use bluetooth, returned item [ DAVID Dec 17, 2016 ]
Bought this adapter for totally different reason. I have older model only integrated amp with no subwoofer input/output connection. I wanted to hook up Martin Logan sub which had typical sub connection Or ex jacks. The int amp had nether option. So I attempted to use speaker wire from int amp to one end of adapter and ex jacks from sub to other end of adapter,, did not work. My sub sits quiet. Will b buying better and newer Int amp (luxman) and pass currrent amp to my son. If anybody can offer advice on how to use sub currently,, I am all ears [ James Dec 17, 2016 ]
If I understand correctly, you wish to run your speakers and this adapter from a single pair of stereo-speaker outputs, that is, you don't have a speaker A/speaker B/both switch and A/B speaker outlets. I recommend consulting with the manufacturer of your amplifier. This device should not draw a lot of current, so it might work, but it would be a shame to destroy your amplifier. [ Christopher Oct 28, 2016 ]
Yes, this will be in parallel with the speakers and send a signal to the sub amp. This has a left and right in and provides a left and right out with RCA. If you only have one in, use a RCA Y to go to the amp or jump the line inputs on the board together (+ to + and - to -). [ Dustin Oct 24, 2016 ]
Wrong Direction - product is an adapter for "speaker-level to line-level" [ Brad Mar 07, 2016 ]
No I don't think so. This device is for reducing speaker output signal down to line level as to not fry your subwoofers power supply. If you're already at line level output from the receiver then this is unnecessary [ Alexander Feb 25, 2016 ]
CAN'T help, the produft didn't work for me, returned [ DAVID Feb 25, 2016 ]
In short, no. This device is used when trying to acquire a line level (pre-amp) signal from a device that only has a high level (speaker;post-amp) output. Your receiver has a line level (pre-amp) output which needs to feed an amplifier which will in turn power (drive) your in-wall subwoofers. Most home audio receivers are designed to be accompanied by a powered sub-woofer. That is why your receiver has a line level output. Depending on what kind of low end response (bass) you want a powered sub-woofer will most likely be the most ecinomical option. [ Michael Feb 25, 2016 ]
sorry i don't know as i used it to convert speaker wire on my amp to line level inputs on my sub [ mike Feb 25, 2016 ]
Tried it and did not work in my situation,,, never used it [ James Feb 05, 2016 ]
I didn't have any of the parts on hand, so I started to order them on line. By the time I got done with the 1/2 W 5% resistors, good-quality connectors, and a box to mount them in plus shipping, it would have cost less than $39.99, but it cost enough that I decided it wasn't worth the time to put it all together myself. If you have the components on hand, by all means make it, but you'll save time and get a very well-build item if you order it here. [ Christopher Feb 04, 2016 ]
It is well worth the price. Solved a very hard to find product. Most other similar products I found were only used in auto speakers that would not stand up to whole house speaker systems. They melted down. [ ROBERT Feb 04, 2016 ]
It was worth it to me because it solved the problem I had of hooking wireless headphones into my home theatre setup. My wife is happy because she can have headphones while the rest of us have surround sound. In my experience a happy wife is well worth $40. Your mileage may differ. Sure it's probably a high-margin product. So buy the parts and build one yourself. [ Peter Feb 03, 2016 ]
*works great [ AARON Feb 03, 2016 ]
It does seem a bit steep, but I bought one and it would great, so I'm happy. [ AARON Feb 03, 2016 ]
Yes sir it can be. I use one in my car and my home audio system. Buy this instead of those cheap ones. You will not lose any sound quality with these. Very good product. Highly recommended. [ CHRISTOPHER Jan 09, 2015 ]
This is for a home amplifier. Chat with the techs at Crutchfield. They have ones specifically designed for car audio systems. [ David Jan 04, 2015 ]
It's just a series of resistors, it will work with any amplified signal regardless of it being car audio, home audio or pro audio. [ ROBERT E Jan 03, 2015 ]
I would think so that's what I'm doing with my Lexus LX 470. I bought this one because it's higher power my old one actually burnt up [ Robert Jan 03, 2015 ]
