soundstream balance line pinout

russdeanlee · 29th June 2012, 05:58 PM

on old school soundstream reference picasso blue board chrome amp is it possible to use the balance line input without the BLT module. can anyone give me a pinout of the balance line input. i want to send my pioneer p880prs speaker outputs straight to the balance line input. i understand there is a +/- 15v on 2 of the pins i think the 2 on the bottom that are vertical from each other which i don't plan on using. Would this work or should i not do this?

I think that you'll have to try it to see if it produces acceptable results for your system.

thanks mr babin, from your experience if my rca is putting out 5v if i was to use balance line would my sound quality improve or it wouldn't make any noticable improvement?

I don't know. The speaker level outputs may be a bit noisier but you could reduce the gains so it may be better overall.

INPUTS ARE REVERS THE OUTPUTS FO THE BLT
BUT YOU MAY RUN INTO gl OR GRUNDING ISSUES USING THE SPEAKER LEVEL OUTPUTS INTO THE AMP SHY NOT GET A BLT AND RUN A BALANCED CABLE BACK TO AMP...

I used to have four BLT4's in my car, now I am only using one and using RCA for the rest of the amplifiers. I doubt they make that big a difference, but some say they do.

At 40 mph, many of the small improvements we invest in disappear in the background road noise.
