Using DBX-40 without a tape deck

I just picked up   DBX-40 noise reduction unit  and a couple of lps with DBX  compensation . I do not use a tape deck and there is no "tape output" channel"  on my discrete preamp and amp.   Can I connect the DBX-40 directly between my preamp and the amp? Will it introduce much distortion if I leave it in when I play "normal" records?

Thanks in advance for anyone who can answer this stupid question. 
Could my DBX-40, alternativiely,  be introduced immediately after my high level phono cartridge and before the preamp?
Might my post be better placed on another thread? Digital or whatever?
Dear @mazikrav: You can do it but that unit will make a " terrible " degradation to the audio signal.

Its specs are really very low-fi: 

Frequency response: 50Hz to 15kHz

Total harmonic distortion: 0.5%

These is what owners posted ( from those old times. ) on that unit:


  1. The problem with the NX-40 is that it was a super cheap unit that dbx introduced in the early 80s that was based on their new (at the time) dbx ICs. Unfortunately the NX-40s never worked very well. I know this becuase I used to own one when I was a kid.

    They overload super easy, making it more diffcult than it should be to set your levels.  """"

Thank you VERY much. I'll only plug it in when I want to play lp's encoded with their program.  I do this on your advice and I thank you again.
