Featured review
Using it on a receiver that has no pre-outs so that I could hook up an amp, works great. I did not realize it was such a simplistic circuit and could have built it myself for a fraction of the cost, but do not regret the purchase. Took a star away because there is no cover, WYSIWYG.

Features
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.

I needed to convert my amplifier's output into a line-level output for input to my SVS subwoofer. SVS recommended the Russound ADP-1.2 unit. It appears one of the few of these converters that is meant for home stereo application and not for automotive applications.

Q
Can a AVR speaker out ( amped with a speaker ) be split to continue to run the speaker, and using this, create a secondary line level output that could be hooked to a line level meter ?

I bought an old 1995 Technics rack system, which had no auxiliary RCA signal out. I use this to send a signal out into a modern Pioneer amp so I could run that system in conjunction with the old Technic system just for kicks. The Technic came with a CD player and a dual cassette deck and a graphic equalizer. It worked fine reducing the higher wattage speaker lines into a low impedance RCA out. The Pioneer runs two tower speakers and a powered subwoofer. It's holding up well. I assume because it reduces the higher wattage speaker lines to a lower level out impedance that it wouldn't give a true reading for a line level meter. Not an expert though.

Q
what is the frequency response of this device?
[ casey Aug 07, 2019 ]

I don't know the exact frequency response of the device(it's also not on the manufacturer's website) but I was using it for about a year to convert a speaker level input to line level for two Dolby atmos channels. My receiver had line outputs for all channels but only had speaker level outputs for the atmos channels and I was running seperate amps for all channels. It worked with no issues and I was previously powering the two atmos channels with the receiver. I did notice that after running the Yamaha ypao(yamaha's version of a parametric equalizer) after I installed the russound convertor that the corrected frequency response curve did not change at all. So even though the manufacturer doesn't list the frequency response I believe it is flat from 20 hertz to 20,000 hertz, or close enough to flat that most ears could never tell the difference. Also it can handle 250 watts rms per channel. I hope this helps in your quest for great sound!

It does works. It's a great product.

Russound adapter is rated for 250 watts per channel.
Your AMP exceeds this rating by 12.5 watts per channel.
So, unfortunately no.

Can I use this to convert second speaker out on a Fender guitar amp to line level to go into recording interface?

This Crutchfield Line-Level Adapter is well built and likely to work to give you an independent second speaker output. The Crutchfield product is a basic L-Pad attenuator circuit. I personally feel a T-Pad attenuator circuit is superior to an L-Pad circuit, particularly when your input impedance is different from your output impedance. I wish Crutchfield made an adapter using T-Pad circuitry. The Carver AVR product from the late 1980's employed the T-pad circuit, using three balanced resisters instead of two. Unfortunately, this product has not been available for over 10-15 years. I recently built my own T-Pad attenuator circuit, patterned after the Carver. It works beautifully with undetectable distortion. You can find these basic circuits on-line.
I recommend you try out the Cruchfield (low cost) product. Should you not get it to work satisfactory, you can explore the T-Pad option. D. Parcel

Possibly, but the problem I see is the wire entry points are to get their signal from the speaker out terminals of a power amp and the RCA jacks on the device are on to convert to the signal back to line level to go back into a power amp. I'm guessing the jacks on the guitar are meant to go into an amplifier as line level and are already at the line level. I'm using the device to take the speaker wire from the power amp and convert it back to line level to go into a subwoofer that has line level RCA inputs. My main power amp does not have subwoofer outputs. Sounds like you could just put the RCA from the guitar directly into the auxiliary RCA input of your stereo preamp and record directly from the guitar.

I had a home theater in a box receiver/speaker system with a passive subwoofer driven by speaker level outputs from the receiver. I wanted to substitute a powered subwoofer so I bought this device to convert the speaker level output to line level. The device did the job. Since it is a bare circuit board, I mounted it in a plastic box for protection. One footnote, after installing the device, the speaker worked fine but there was some ground loop isolation hum. I purchased a ground loop isolation transformer and that immediately solved the problem. I do not know if this was related to installing the line-level adapter.
I cannot state for sure that this adapter will work for your desired application, but given my experience, I think there is a good likelihood that it will work.
