bose 901 and i pod

I actually used this forum for a recommendation of what  i needed to make this happen and i purchased this unit to accomplish the integration. . I was able to hear them with out the equalizer and was definitely not happy with the sound.So I returned the amp and B1 unit and going a different route.Got some advice that was not necessarily the best.

'Thanks for your help 

Yamaha A-S series has neither pre out/main in jacks nor a tape monitor loop. So you won’t be able to use the equalizer with this amp. Links below to the similar A-S801:

I would sell your Bose and look for some speakers that don’t require an equalizer unless you want to get a tech to add the pre out/main in jacks (an expensive mod no doubt)

It’s possible the EQ needs servicing. It’s somewhat common and there are a couple of places around the US that can service/ rebuild them.
