  • Input: Stereo 24K gold-plated 5-way speaker-level binding posts allow bare-wire, spade, or banana connectors.

Description

Add pristine speaker-level to line-level subwoofer connectivity with no loss of fidelity. For use with integrated amplifiers and legacy stereo receivers that lack line level or subwoofer outputs. Easy setup with high-quality speaker-level binding post inputs, and stereo RCA line-level outputs. Many integrated amplifiers and legacy stereo receivers lack line-level outputs, leaving enthusiasts without the ability to connect a powered subwoofer to their system. The SVS SoundPath Speaker Level Subwoofer Adapter elegantly solves this problem by stepping down the loudspeaker amplifier speaker-level voltage to RCA line-level voltage, allowing for a safe connection to a powered subwoofer with no loss of fidelity. With a minimalist design and premium components, the SoundPath Speaker Level Subwoofer Adapter ensures pristine and transparent signal transfer to the subwoofer without compromising any part of the playback system. Stereo Gold-plated 5-way speaker-level binding posts allow bare-wire, spade, or banana connectors. Gold-plated stereo RCA line-level output jacks ensure a secure connection to the line-level inputs of the powered subwoofer. Works seamlessly with a pair of SVS SoundPath RCA Subwoofer Cables. Features premium grade narrow-tolerance resistors and wide-trace PCBs for high-current and extreme power handling. The uncompromising design yields wide bandwidth and ultra-low distortion for pristine signal transfer, pinpoint accuracy, and compatibility with all high-end audio systems. -30 dBV attenuation will not draw any power from the loudspeaker amplifier ensuring a safe signal for the subwoofer line level inputs. SVS SoundPath Bi-wire Speaker Cable can be used for an easy and elegant connection to both the loudspeaker amplifier and the SoundPath Speaker-Level to Line-Level adapter.

Outstanding product
This is exactly what I needed to run my Klipsch powered 10 inch sub with my vintage Pioneer VSX-4400 A/V receiver. It was easy to wire up and the sound quality is outstanding. SVS makes a quality product.

Perfect for Feeding My Audio Meters
I use the SVS SoundPath Speaker Level Subwoofer Adapter a little differently than intended. I needed a clean line-level signal from my speaker outputs to feed both my VU meter and spectrum analyzer, and this adapter does the job perfectly. It gives me the signal I need without interfering with my normal speaker setup. It's compact, well-made, and has been completely trouble-free in my system. If you need to convert a speaker-level signal to line level, whether for a subwoofer or other audio equipment like mine, this is a simple solution that works exactly as expected. ... show more

No subwoofer - I had a different problem
I run my L/R speakers in a 7.1 system through an external amplifier and the AVR does not pass digital input. It was only after I connected everything did I find that the L/R speakers go silent with HDMI (move/TV) input. I attached this thing to the L/R speaker outs. I could have tried a cheaper, automotive style converter but after the time and hassle of this installation, I didn’t want to waste more time dealing with potential noise issues and this thing is quiet. Any perceptible signal degradation from using high level outs is IMHO impossible to detect in a movie context. Or any context. Some people slam these things for theoretical, audible differences, but numbers belie this. For the truly obsessive, here’s the RMS calculation from my adding this device: Rated distortion for the AVR and my PS Audio S300 power amp respectively are .08% and ≤.02% totaling √(d12 + d22)=.082% (that's SQRT(distortion 1 squared + distortion 2 squared), no superscript here), a difference you cannot hear as the threshold of IM distortion human audibility is generally considered to be .1%. This is simply a well made voltage divider. It adds no noise and solves a big problem very economically. I recommend it. ... show more

Works great just a little too expensive
Works as advertised. No problems. Little expensive though.

very very weak signal.
the line level signal coming off this thing is so weak that I have to run it through 3 separate amplification stages just to hear anything. There is so much gain that you can hear a hiss from the speakers like you do with a phono preamp. For reference, I do have this connected exactly as it is described in the instructions. ... show more

One Soundpath works fine with dual subs ....
I have a pair of SVS PB12-NSD subs that compliment my Klispch RF7-II tower speakers. I needed a solution to get the best performance when driving this combo with a KT88 push/pull tube amp. The Soundpath adapter works very well. I simply run a parallel set of speaker wires from the amp to the Soundpath and then a pair of subwoofer RCA cables to each of the subs. One cable is "Left" out of Soundpath to "Left" IN line level on the left sub. The same goes for right side sub. The crossover for each sub is set to about 50Hz with gain at about 75%. The Klipsch go down to 30Hz so filling in the area between 30 and 50Hz using the Soundpath works extremely well after tweaking until everything is blended nicely together. Volume control between the subs and speakers is very linear, one does not dominate the other when using the volume control. The mixing seems perfect in my setup. So, I seemed to have solved my issue and very happy with the Soundpath. It's affordable and well constructed, no complaints. ... show more

Perfect for Home Systems including Vintage Receivers with no RCA outs
PERFECT - this solved my issues with my Garage vintage Home Receiver conversion to running a powered 12" subwoofer from Klipsch. Tried 3 top tier car converters, but they all sucked. Also purchased the PAC boost controller knob to make adjustments, perfect. With some fine tuning, this system sounds awesome - now I'm constantly getting yelled by my wife to turn it down because it's rattling things in the house. I'm sure my neighbors love me even more now. Highly recommend... ... show more
